Hobbyking Yak 55 3D 1096mm EPP (ARF) (USA Warehouse)
This great size Hobbyking Yak 55 has been designed with 3D flying very much in mind, made from virtually unbreakable EPP Foam, it is ideal for practicing 3D maneouvers over and over, get it wrong? No problem, the Yak 55 will just bounce and even if you do get it horribly wrong, 5 minutes and a bottle of Cyano & Kicker is all it takes to restore your pride and your Yak.
This is a superbly designed, top quality Almost Ready To Fly model that features a proper profile wing and extensive use of carbon fibre rod & CF square tubing for extra stiffness. The control surfaces are large enough for any Hard-core 3D pilot, but just to make double sure you are happy, the model comes with servo horn extensions for maximum throws. Big wheels that can handle almost any flying field & plug in wings secured with rubber bands for easy strip down and transportation add to the list of practical features.
The motor mount is pre-installed and will accept up to a 35mm brushlessoutrunner, the lipoly mount with pre-installed velcro strap is a perfect size slot for a Turnigy 1800mAh 3s and to do this brilliant model justice, we reccomend digital micro servos all round. The Hobbyking Yak 55 flys really well, so well that even if you are not interested in 3D flying, set it up on low rates and it makes a brilliant parkflyer. However you choose to abuse....sorry.....use your Yak, its a huge amount of fun and at this price .........can you afford NOT to have one!?
I'm using the following with mine and it's awesome:
NTM Prop Drive Series 35-36A 1400Kv / 550W (USA Warehouse)
NTM Prop Drive 35 Series Accessory Pack (USA Warehouse)
TURNIGY Plush 60amp Speed Controller (USA Warehouse)
APC style propeller 10x5-E (USA Warehouse)
Make sure to get 4 digital metal-gear 13-15gram servos too.
Hi Lucas, Ignore the "4 x 9g digital servo" spec shown above. This plane is way too big for 9g servos. I'm using 12g-13g metal gear servos and they have stood up to the abuse of 3D flying with no problems. A few item numbers to look at are PRODUCT ID: TGY-9018MG, PRODUCT ID: DS-929MG, and PRODUCT ID: DS939MG. Just copy/paste the ID into the Search box at top of page and the link to the items will appear. I've used all 3 of these servos and they're great ... quick, precise, strong, and cheap. Cheers, EA!
Hello I have a Turnigy 480 1320 KV and 35 Amp HK ESC-Is correct? . What propeller and battery should I put in for it flies like a charm?? I fly park flyer for five years but I want to start in 3D! Thank you very much!
Hi steph005, You picked a great motor/ESC combo for this plane. I fly this plane with the same motor and a HK BlueSeries 40A ESC and it's great for 3D. For props, try a 10x5 or 11x3.8 and you'll have plenty of thrust for 3D without overloading the motor. I use both 1800mah/3S and 2200mah/3S on my plane. The CG is perfect for 3D with the 1800mah, but the 2200mah gives longer flight times without sacrificing too much 3D performance. Cheers, EA!
What the fuc hobbyking i ordered batteries and esc's last month i ordered stuff this month and its here already it take 7 day to get from hongkong to me in arizona and it takes 7 day if it comes from lakeside.. were going on a month for my order of the batt. & esc's.. whats up with that????? and its not the first time you have done this to me. is it any wonder why i have given my business to n/i/t/r/o/p/l/a/n/e/s and h/o/b/b/y/p/a/r/t/z/.. its funny too because i use to be a loyal customer untill you tried to screw me over one to many times. i can say that hobbyking keeps me from flying. hell of a note for a hobby store dont ya think. why dont you fix the way you treat people and do business. you went from my hero to a real zero and i think your suppost to do it the other way around
Couldn't agree more. Customer service is not only useless but downright rude and insulting. Only business I'll be doing is at the Lakewood warehouse 10 minutes from home so I can inspect the order at will-call and refuse it if it's wrong or missing parts or damaged which more often than not seems to be the case these last few months. I've spent thousands here but no more. HK has gone completely to hell in a hand basket and lost a ton of loyal customers including myself. Nitro and HobbyP for me too from now on.
Hi Peter, The site shows slightly lower prices (members price) when you're logged than it shows when you're not. You might want to check your order confirmation email to verify which price you paid. Cheers, EA!
i just got mine in the mail today feb. 4th still waiting on hk to get my new batterys to me so i can maiden my 3 planes all at the same time.. i think ill goop the wings together on this one dont trust the rubberband. i found a old 3540 1300kv motor to start with ( im trying not to spend much more on this hobby and have more money in rc airplanes that most of my friends have in there house )ill run metal gear servos in the wing and some cheapies like hxt900 in the tail a hk 40 amp esc and rhino 3s 1750mah 25c with a orange 6 ch or maybe a sp[ektrum ar600 i got laying around will do a review when im done and maiden it... later dudes
Hi wild, This plane has a rep for high-G wing-folding. That little CF rod that joins the 2 wing halves via the spar will fail and the wings will fold up unless you 1) epoxy the whole area fixing the wings in place or 2) add another bridging piece(s) between the wing halves. Cheers, EA!
Withdrawn, you sound like me, I got the Zephyr V70, the Bixler after a three month wait and the Yak 55 now all new winter projects and will go up for the first time this spring. I did read up a lot on all three anticipating the builds and ended up using Goop on the Yak's wings. A lot of feedback on guys having problems with them failing.
I paid $57.28 Jan. 22. I think maybe after looking at my membership status it may be cheaper now because I am now a Platinum Member. So my theory is keep sending them orders and pretty soon the'll be sending everything to me for free. Very Cool
Hi wild, Sounds like you built your Yak good and stout. Our mods are similar, as I used two 1mm x 6mm x 400mm CF strips, one each side of the main spar. It's been bullet-proof so far. The plane can really take the abuse I dish out with no problems. Cheers, EA!
Did you guys beef up the motor mount any? I've seen a couple pictures of them failing and was thinking of notching out the foam and sliding another piece of plywood in and gluing it all back up. Mt props I chose are pretty stiff and might not give out before the thin ply they have provided.
Hi Peter, The motor mount is pretty solid and I didn't have any trouble with it until I dropped the plane on its nose from about 10 feet up. That snapped it right out of the plane. I made a new one from 4mm ply and it has been bullet-proof. It wouldn't hurt to brush the whole area with epoxy (if you have some) just to tighten/toughen the mount up a bit. Cheers, EA!
i had to drill out a new pattern for my motor mount and its real close to the edge of the plywood firewall mount so i m thinking maybe gluing some formica over the top its strong stuff and the samples are free at homedepot and are big enough to do a weedeater motor. lol a little gorilla snot should fix her up pretty good and bond it together like crazy without adding much weight to the nose. thats at the risk of looking like a flying counter top
well the only thing missing now is the batterys and esc's. i was able to put a formica sheet both in front and behind the stock motor mount redrilled the mount holes.. they say the weather is suppose to be bad this weekend so i m praying for delivery from hk before it starts.. if ya cant tell im dying to maiden the three of my planes the flying field is dried out and im ready
well another day and no shippment from hk. in a time long long ago and a place far far away the hk shipments took less than a week to get here or should i say back in the day! the funny thing is for a hobby shop hk sure keeps me from flying
Hi wild, If your order was from the international warehouse, it's pretty typical for this time of year .... the Chinese New Year period is at its peak. Half their staff are out celebrating. Cheers, EA!
I have been waiting three weeks on a Hong Kong order, their a bit slow right now, although I order a balance charge board from ebay and got it in 7 days from Hong Kong. Who knows. I'm not doing much better with HK USA as I submitted a faulty part claim, got one response after two days and hav'nt heard from them since then. I'm loosing faith. You would think on a $150 plane with a DOA servo, they would send me one right away. Good Luck withdrawn
Hi Peter, Keep the faith. I know it's frustrating to deal with a few problems early on with HK, but their general track record is pretty good. Look at it this way, you've probably used up your whole "trouble quota" by now so it should be smooth sailing from here on in. When you look at the price of gear from them vs. the other hobby houses, you're well ahead even if a few items go belly up on you. We couldn't survive without HK in Australia, as our gear is generally priced 50% higher than US prices. Cheers, EA!
Update, my tracking number finally worked today. After ordering two weeks ago it finally made it to the Singapore post office. Zephyr V70 with bad servo, they finally responded today saying they need more proof that it's faulty after a 12 day wait, Bixler arrived with bend foam on wing-tips, requested RMA number for return and never got any response for a month now. Zippy 2500mah transmitter battery DOA. Never even tried, just took it to Radio Shack for free disposal. I'm beginning the 50% would be worth the lack of aggravation. Yea, I'm frustrated. Yak 55 sitting on kitchen table awaiting parts. Wife frustrated also. Always wanted RC planes. these three are my first. Never flown. Hope I live long enough to have my first crash.
Hi Peter, You've had the worst run of bad luck imaginable. Here's a suggestion that might get HK off their backsides to resolve the problem. Click on the "Forums" button at top of page. Scroll down to the bottom and you'll see "Complaints Department" which is where you should give the whole chronology of problems you've had with HK. Make the subject line something like "FIRST-TIMERS 3-MONTH SAGA OF PROBLEMS WITH HOBBYKING" to really get their attention. HK reads this Forum topic every day and they usually respond quickly because of the high visibility of your post to all HK customers. When they respond to you, demand that they credit your Bonus Points some reasonable amount ($50-$100) for all the trouble you've had. Cheers, EA!
It seems I can enter any forum I select except the Complaints Department. It says "
Only members with sufficient permission can access this page."
I could see that you we viewing Electric Aussie. When you were not viewing the Complaints Department didn't even show up in my forums list.
Hi Peter, Were you logged in when you tried. I don't remember if you have to register for the Forum before you can use it, but you should be able to log in if you've made a few purchases. Try again and if you can't get access then I can't offer any other suggestions. I had an issue with HK last year and became very vocal on that board .... it got resolved .... fast! Cheers, EA!
Hi wild, I use shims on an as-needed basis based on how the motor appears to sit when mounted. If I can't see a noticeable amount of right/down thrust I generally add a few shims until I can see 1-2 degrees of angle. Then I fine tune after I've trimmed and flown the plane for a while. Cheers, EA!
Hi ElectricAussie, Yes, I had to add a user name to my profile but even then it would let me use the complaint dept. You can see I had to add a number to the end off my name to get logged for the forums.
I HAD TO OPEN A DISPUTE TO DAY WITH PAYPAL ABOUT HK LAST TIME I DID NOT RECEIVE WHAT I PAYED FOR HK KEPT SAYING PLEASE WAIT THAT WAS TWO YEARS AGO AND IM STILL WAITING BECAUSE I LET MY TIME TO FILE A DISPUTE RUN OUT AND HK NEVER SENT THE ITEM I PAID FOR. I JUST GOT DONE TALKING TO ONLINE SUPPORT AND THEY SAID PLEASE WAIT. YEAH LIKE IM REALLY GONNA DO THAT AGAIN BESIDES THE ORDER IS FOR OVER A HUNDRED DOLLARS ON ONE ORDER AND 12 BUCKS ON THE NEXT THAT I PAID FOR LAST MONTH AND THEY WONDER WHY I CHAMPION N/I/T/R/O/P/L/A/N/E/S/ ITS CHEAPER OVER ALL PRICES CHEAPER SHIPPING AND FAR BETTER BY LEAPS N BOUNDS ON THE CUSTOMER SERVICE BECAUSE THEY COULD'NT BE ANY WORSE THAT HK'S ALMOST NON EXISTANT CUSTOMER SERVICE.. YOU CAN REALLY SAY HOBBYKING KEEP ME FROM FLYING AND THATS PRETTY SAD
Well Wild, I opened a dispute 17 days ago and have gotten two replies thus far. Neither to my liking or fair. I told them what I would except totaling about 22 bucks from them. This is all after jumping through hoops with pictures, then they wanted a video. I went and paid $229 for a video camera and then couldn't upload the video to their site so I put it on youtube. www.link it's not the fact that you ended up with a DOA servo, it's the principle of the matter. Hang in there, I am.
THATS WHY I OPENED IT WITH PAYPAL THEY WONT PAY HOBBYKING UNTILL I GET MY STUFF OR THEY WILL BACK CHARGE THEM IF ALL READY PAID.. I M GETTING REAL TIRED OF HK BULL**** ALL THE TIME TAKING ADVANTAGE OF THE COMSUMMER THE ONLY REASON I BOUGHT THRU THEM THIS TIME IS THE OTHER SUPPLIER WAS OUTTA STOCK.. HOBBYKING HAS GOT TO KNOW THE WAY THEY TREAT PEOPLE IS RUNNING CUSTOMERS OFF TO THEIR COMPETITER.. I USE TO BE A LOYAL CUSTOMER BUT NOT ANYMORE NOT AT THE RATE HK IS GOING. ANYWAY DUDE I WISH YOU LUCK ON YOUR DISPUTE.. LATER DUDE
Hi Bob, I set mine up with lots of throw (>45 degrees) on all control surfaces and 70% expo. With the high expo it's pretty docile around the middle of the sticks, but the 3D moves are there when you want them. I don't use dual rates, but 60% would probably be about right if you're a bit nervous on your first few flights. This plane is very linear and predictable in its flight characteristics. Little or no tip stall or other bad habits. Cheers, EA!
RC_Rick * * * *7/11/2012 9:55:00 PM
Hi, is anybody have wing dimension at the fuselage and the dimension on the tip of the wing. I want to calculate the wingloading to know of it can fly slow like th�* reaktor 3D. Thanks
Hi Rick, 305mm at the root and 190mm at the tip. I have the Reaktor and these 2 planes have become my absolute favorites. The Reaktor is a little more floaty than the Yak, but the Yak will do everything the Reaktor can do, just not as quickly or in as small a space. The Yak slows nicely for landings and never drops a wing, but needs a little more speed than the Reaktor. The upside is the Yak is much more wind-tolerant and stable/precise thru most 3D stuff. The wing can fail at the center under hi-G if you leave them removable. Epoxy them in place. Cheers!
hey EA what setup are you running in both the reaktor and yak i having trouble finding a great setup that cheep.. oh and my yak is 55 1200mm w.s.from a different supplier up to 900g a.u.w. any suggestions
Hi wildthawn, In the Yak55 I'm running a Park480/1320kV on 1800mah or 2200mah 3S. AUW in the mid-800g range. Flies fine and can do most 3D stuff, but feels sluggish compared to the Reaktor. On the Reaktor I've been using the HK D2822/14-1450kv (PRODUCT ID: D2822-141450) and it is awesome combined with 20A HK BlueSeries ESC, 850mah/3S nano-tech, 8x3.8SF prop. AUW comes in around 340g but the plane floats at a slow walk. Cheers, EA!
Has anyone had trouble with the wings folding under high g maneuvers with max elevator throw. Any ideas on good ways to reinforce wings? I LOVE this plane. It really locks in for a good hover / torque rool and has great slow flying characteristics.
YES! I had a pretty bad crash where the wings folded up under a high g maneuver. The unfortunate solution is to glue the wings. On the plus side, I have crashed with glued wings and they will *tear* at the fuse, slide off the carbon fiber rod (don't glue the rod in), and still make a clean break that is very easy to fix with CA and kicker. Once glued you will be able to do unlimited 3d with no fear.
I can't seem to find the right CG spot, book says nothing about CG, I was told by someone online to try 130mm and that was too far back it flew like it had a lead ball on the tail. I have it set-up with the same equipment, bat, ESC, etc. as the recommendations and video! I rechecked my build out for mistakes, all is OK, wont fly right! Using the 1/3 rule for CG I have to add a 3s 2200amp lipo bat. under nose, just under motor to get it to balance at the 1/3 rule..way too much dead weight! I tried it anyway..no go, now too much weight in the front! Can someone give me a good CG and possible issues, am I doing something wrong?
I built by the plans and used metal gear servos so mine came in tail heavy. I found the best cg at the center spar, 115mm from leading edge and I had to add 2 oz of nose wieght. Flys like its on rails, this is a great plane just play around with the cg until it flys best for you..
Will any of these Motors work with this plane? If so, which would be most suitable for a fast, powerful, capable of hardcore 3d or just a fast parkflyer plane?
If not, any motor suggestions?
Turnigy G25 Brushless Outrunner 870kv
Turnigy G15 Brushless Outrunner 950kv
Turnigy G10 Brushless Outrunner 1200kv
Turnigy Park480 Brushless Outrunner 1320kv
Thanks for any help, it is greatly appreciated.
G25 and G15 is for bigger planes...
G10 850kv is a little heavy for this plane but still can do..
park480 should be good with this plane..
I have yak54 profile epp with motor EMAX BL2215/20 and 10X4.7SF and have plenty of power..I think it can be good on this plane also
I would definitely go with the bigger G10 motor rather than the E-flite 480. I am pushing about 400w with my motor and it fly's nice. i like that i can run either a 11x5 or 10x4.7 prop and this plane will 3-d. you wouldn't be happy with the 480 for what you described as being your goal. I built mine a little heavier than some i am sure. I used hs-82mg servos in the rear and 9g mg servos for ailerons, 40 amp esc and i use 1600-1800mah 3 cell 40c batteries. i built my own motor mount to accommodate the larger mounting pattern of my motor. The motor mount is one of the weak spots of this plane. Mine balances perfect though with this setup. Good luck this is a real fun plane.
Ok Jeebs thank you I thought 480 may be weak for my wants. If i may ask, what motor and esc are you using?
Ive read that the G10 shaft is not "square"
Which of hobbykings motors are equivalent to the G10's power and performance that ive also read about?
I am using an Exceed Rocket series 2814-1035KV Brushless Motor. It's around 400 watts with a 10x4.7 and a little more with the 11x5. i use a 40 amp esc. Even with a 10x4.7 I can pull out of a hover nicely. the 11x5 is even better but lately i have been flying with 10x4.7. The small prop creates a nice amount of airflow over the control surfaces and minimizes the torque effect. If i want to torque roll I do need to use ailerons. be advised though i did make my own motor mount to accommodate the larger mounting pattern of the motor. I have found the motor mount to be one of the weakest parts of the plane. the other is the landing gear. i put a piece of light balsa as a wedge to hold the gear in, it absorbs most of the stress so the actual landing gear mount stays intact. I figure i can replace the small balsa wedge easier than the whole landing gear. This plane is really fun so you'll be low to the ground in no time at all. good luck
Has anyone tried running a DT750 motor from HK? I have several laying around. The guys at FliteTest used one in their EOT Rare Bear which is a very similar plane. I'm not looking for maximum vertical performance, just a slow flying snappy type plane.
1 thumbs up!
Useing D-MG16 Metal Gear Digital Servos. Tacon 35mm 1100KV 450watt motor, 1550mah 40C 3 cell lipos, OrangeRX R610 receiver. Small issue during build, wing cut-out in fuselage needs to be cut larger for wings to fit. Wire landing gear a bit too soft and easily bent, could use larger diameter tires. Final flying weight was 850 grams. The motor was a bit heavy for this plane, but the power more than corrected for this. Was very 3D capable. Suggested CG is a bit too nose-heavy for 3D. I set my CG at 15mm aft of rear face of carbon fiber wing spar. Plane is far more capable than my 3D skills. Highly recommend.

Can I use this prop- Turnigy Ultra-light wood propeller 11x7 or 10 x 6 & Below is my setting -Test flight is tommorow TR 35.36 1100 KV MOTOR ,40 Amp ESC with BSEC & NANO TECH BATTERY 1800

What a great plane to have fun with, much better than the Telink version. No need to infuse carbon (already done.) Assembly was very easy. Only issues I had were the landing gear to bendy(now removed and I hand launch it) and the battery tray size. I had to make a minor adjustment to battery tray size now can fit 3s 2200/1800/1600 Nanotechs. I'm using a Donkey motor w/ 40A Mystery ESC and 10x4.7 sf prop, nothing gets hot, but the flights are awesome. Wings don't flex like a lot of EPP models. I'm very happy with it, with only minor customization required. Sorry no watt data, was to excited to fly it. Now have over 20 flights on it with no issues. Overall great plane, wish you had more like it.

Here is a Video of me flying my Yak 55! I have Corona 939 in the ail and 929 in the rudder and Elevtor! Great Plane for the price! I wish they would stock in www.link

Put a 480 in this, stick a 1300 3s in it, attach a 10 x 7, balance it on the "apar" and learn to hover, fly inverted, do clean inside/outside loops, roll, waterfall, more-or-less flat spin upright or inverted—all in slow motion. This plane is the perfect 3D trainer. It a great combination of snooze and adrenaline rush!
