The YAK54 is a very neatly designed EPO 3D parkflyer. With smart features such as side-flip canopy for super fast battery & wing removal, 1 nylon bolt wing brace and unique rudder hinge system. This YAK54 doesnt borrow hinges or horns from the parts bin, its all totally new, resulting in a plane comprised of parts that work together better, reducing weight, increasing strength and ultimately making it a more enjoyable plane to fly and work with. Because of its weight, the YAK54 only needs a very economic motor system, the 2408 sized brushlessoutrunner gives more than enough power on a 2S 1,000mAh battery. You dont need to buy expensive batteries to enjoy this plane, 20C is all thats needed! The large control surfaces and quality included servos make this very 3D capable. Wing moulding and fuse fit together perfectly with unique servo locations and you wont find any ice-cream container cowling here, its all EPO!
This is a well designed and totally new 3D parkflyer that wont dissapoint even hard core 3D pilots. Its scale details visiually appeal and are backed up by its flying ability!
Plug it into another channel (elevator) and see if it works.
If not the servo is bad and will need to be replaced. If it works, then there is a problem with the receiver or the transmitter.
Troubleshoot this if need be by trying a different receiver.
If it is the servo, they are easy to replace.
Look at Master Airscrew 6X4 3 Bladed prop. You might need to do some slight modifications or some slight creative installation, but when you are done, "the improved performance is well worth the effort".
Ignore it hekitoo. It's some blow in from a kid's forum who doesn't help anyone just comes here to make a nuisance of himself. He thinks he's Kim Jong II. Thankfully dead North Korean dictator, probably one of the worst if not the worst case of "small man syndrome" ever.
Just received this plane today. My first HK order. Plane arrived pre-crashed for my convenience. The box was undamaged. What gives? Wings are warped, damage to fuselage and wings, no instructions?. The also shorted me 1 battery.... Sent a request for help, how this pans out decides if I will ever order from HK again.. cannot recommend this airplane, keep looking. anyone else have this issue with the Yak?
So if you have an issue with HK, this is what to expect:

Thanks for emailing support.
If you have any other questions, please let me know.
So how many people happen to have a gram scale that can weigh 5 lbs or - 5g just laying around?
I've had this plane for a year. was missing a part and they said they'd send me one when they got it from the manufacturer. It's been 1 year since I ordered this plane and i still have not received the missing part.
I have PZ su-26xp for flying when I don't want to go to the flying feild. I TO and land in the street, and with houses and cars everywhere I like that it can't do much damage. Do you think this would be too big to use in the same manner? It is twice the size and roughly ten times heavier.....
I also like to fly a slow and light PZ plane in the street where I live, but there aren't many in that class. From what I have seen of this plane, it is not really a slow flying machine* and I would only recommend a stable slow flying and very light plane to avoid damage to plane and other property. I have been impressed with the flat foam 300S type planes based on simulator flying and have my eye on one of these or ver close. I have seen other planes being used this way, but can't recommend due to what happens if things go wrong.
Can someone please convince me why I should/n't get this Yak, and not the Piper Cub? I used to own a cub, but broke it. Was a really fun, easy plane to fly. I want something capable of aerobatics. I really can't decide :/ Thanks in advance!
i just got this thing yesterday and did the maiden this morning. I used 850mah 2cell, 800mah 3 cell, and a 1000mah 3 cell. the 3 cells rips your socks off but the 2 cell is still very nice and smooth. I really had a ball with it and would absolutely recommend it. I would def beef up the motor mount after a few rough landings. i split it at the seam and loaded it with epoxy and bam! ready to go!
that bigger they are the more stable they are with the wind and all that. I wouldn't be able to comment on electronics quality but it all looks like it would be fairly decent for some sport flying but hardcore 3d needs gnarlier stuff for sure.
Great. I have a 3m roll of hinge tape, very good stuff, cost no more than $3. It really is a good looking plane, isn't it. I might one day buy the 1.5 metre model, which I assume is like this one, but bigger motor, batt. and ESC?
This plane is a scream. I moded it out to fit a 2100 Mah 3S Lipo and I think this is the fastest plane I've ever flown. You can just about take off from vertical and it will do a couple hundered feet of straight up barrel rolling before it stalls.
This thing flys great using the listed 1000 2s battery. Watch the landing gear, mine fell off first flight and is now glued on. had to belly land and broke the prop. The esc roasted after about four flights, now using turnigy plush 25amp. Rudder is useless, flys best just banking and yanking, plenty of power for 3d on 3s, not nearly enough control surface. Watch the landing, this sucker comes in fast.
does anybody know if the esc has programming options? I have added the turnigy 3s 1000mah battery pushed all the way to the front and balanced out nicely at 54mm. She flies fast so reduce throws to 50% to keep this bird under control. any advice or links for esc would be greatly appreciated.
Does the ESC have any model information? Usually the Files tab has the manual file or someone in the Discussion section has more information. Since it it a HK product, I would guess it has a 20 amp HK ESC and you could match model photo.
I did not get any manual with mine where is the CG on this unit at. Also is there something mounted on the inside for the magnet to attach to like a piece of metal or something mine has nothing there to stick to.
boredom is correct for most part
dimensional weight stinks, but i have been buying online from orient for years and they really do offer best shipping prices
most china sellers on ebay charge 10 to 15 times items shipping price from hk for similar larger www.link
I am in the process of making a review on this plane. I will post the review with recommended modifications in less then one week on youtube here, http://www.youtube.com/user/dhdsracer
there are a few more reviews on there and many many more to come.
The esc this plane comes with is made to handle 2 cell batteries or 3 cell battery. Choose your 3 cell carefully for the battery cavity in this plane is very limited to what battery you can use. Make sure you check the dimensions of the battery cavity before you purchase any 3 cell.
Yep, you better get out the Dremel, and start grinding foam, cause it's tight up there by the nose. I am running all my 800mm warbirds on #S batteries. They need it, oh and all the ESCs work fine.
Fun, fast plane. I made a very comprehensive 2 part review on youtube, please check it out if your looking into this plane. http://www.youtube.com/watch?v=PrX79oxretg

My girlfriend purchased a plane for me for my birthday back in April 2011. That plane was on backorder for a month.. So she decided to get a different plane, one that was in stock. We chose the Yak 54. It arrived in a few days from the USA warehouse. The assembly went quickly and when I was putting on the final piece, the rudder, I noticed that the rudder was severly warped and the top clip was missing. I took pictures and notified the support center. They told me that they would have to request a new part from the manufacturer. It has been 3 months and they still have not sent me either a new non-warped rudder with both clips, or a single replacement clip for the one that was missing. Even though they have plenty of these planes in stock in the USA warehouse, they refuse to send me a part from one of those planes which would arrive at my door in 3 days. So, here I am, 3 months later, with a Yak 54 sitting on my shelf, unable to fly it because of a missing clip (and bent rudder part). Should they send customers that purchase the plane today a new plane from the USA warehouse stock and keep me waiting indefinitely for a part that may never arrive? You tell me.

This plane is way too responsive for a novice such as myself. Parts don't seem to be available at any of the warehouses. I would try to fix it if I could get a fuselage. Can someone point me to a part #.
I waited until I have flown this plane for 2 weeks to write this review:
I have ordered 2 of these planes, the first one arrived damaged, but it was an easy fix with some foam safe CA. HobbyKing also gave me a partial refund for the damage to the plane. The claim process is different from other vendors, but do what the HK rep says and you will get action.
The Yak 54 EPO - This is the toughest airframe I have ever tortured. I have literally broken this plane into chunks, glued it back together and it still flies like new. The included motor and ESC are excellent, but the servos should be replaced before taking this plane up. I used 7.5g mini servos and they work well. The wings arrived with about 7 degrees anhedral which was removed with hot water. You want the wings straight at 180 degrees. I also replaced the wheels with larger ones to keep from breaking props, and I also removed the 1oz metal slug from above the motor to get it to balance with the 3s packs. This plane flies like a brick on 2s. Only use 3s. Even the motor has 11.1v written on it. On 2s it will keep you on your toes trying to keep it airborne. On 3s this plane is pretty fast and fun! I recommend the Turnigy N1000.3S.45 they have been working great. I am getting 7min flights from them. Thinking about trying 4s with a different Motor and ESC soon.
The Yak is NOT for beginners. It must be landed with plenty of speed, but will take it if you still make mistakes like I do.
