Hobbyking Walrus Plug and Fly Glider w/Flaps EPO 1400mm
The Hobbyking Walrus is a very capable, fun model that appeals to both new and experienced pilots alike, easy to fly and easy to build, the Walrus is great value for money!
Made from tough EPO foam, the Walrus is simplicity itself to assemble, the colourful decals are pre-applied and the brushlessoutrunner motor, ESC and all servo's are pre-installed, even the folding prop and spinner have been factory fitted! As well as being easy to assemble, the Walrus is very practical and features a stiff, CF reinforced 2pc Plug in wing and a large canopy area that allows you to fit a wide range of lipoly packs, it's somewhat portly proportions also make the Walrus super easy to hand-launch. The great looking scheme is perfect for orientation and it's appealing size gives the Walrus plenty of presence, as well as the ability to handle a little wind.
There is no doubting the versatility of this superbly priced glider, it is perfect for some gentle grab n fly gliding but the Walrus is also suprisingly capable as a Sport flyer, making it perfect for new pilots to progress with as they get more confident. The speed of the Walrus at WOT is quite suprising and with flaps fitted as standard, it is also capable of amazingly slow flight, this combination gives the Walrus an impressive flight envelope for a "reasonably priced" foamy glider! There can be no doubt, regardless of your flying experience.....you can't go wrong with a Walrus!
Features: Plug and Fly - Just add your own battery & radio and fly! Super Tough EPO Foam Construction Easy and Fast to Assemble Flaps Fitted As Standard Wide Flight Envelope 2pc Plug In Wing for Easy Transport Scheme is Excellent For Orientation Stiff Wing with CF Joiner
Includes: All Hardware Hook & Loop Tape Photo Manual Y-Leads
It also depends from how many "C" the batteries has.
1.800 mAh is good for Walrus, since with the original motor it doesn't "drink" so many Amperes, but requires at least 20C of discharge capacity (better if 25C).
In general, higher Kv is for speed, with smaller props, lower Kv is for higher paylad, with larger props.
If the differences are not so big, it's almost the same, but You can calculate everything with "ecalc.ch" an online free software.
Ioannis, I was forgetting an important thing: in any case, You'll have to change also prop spinner.
I must tell You because, if You'll order a motor and You'll wait for the delivery, You'll be disappointed because shaft diameter won't be the same of stock motor.
I destroyed the original spinner, trying to separate it from motor's shaft: there's a small hex screw that, in my case, was glued and impossible to unscrew.
Finally, I've cutted spinner with a Dremel.
It's not straight, has a diversion to the right and a little to down.
It's needed to compensate the effect of the right turning propellers: air goes back with an helix effect.
The air under the plane goes on the left (watching plane from the back), the air above the plane goes right and impacts the tailfin and the rudder on their left side, pushing the front of the plane on left side.
On real planes with one engine, when You give max thrust for take off, You must compensate this effect with right pedal (right rudder), for the same reasons (and also because left gear's wheel is more compressed because of engine and prop's torque)* on Walrus, are enough few degrees on the right of the motor mount.
Absolutely yes! It has been my first plane after some hours at the simulator and the first time I flown it was like I was flying it so long time!
It's very easy to control and stable at low speed but at the same time it can be aerobatic and enjoying.
With full flaps You can land it "on a stamp".
Is also a good soarer (good for an EPO plane of this kind).
I flown it with 10-12 knots of wind and it was even easier, most of all for landing.
The problem is when wind is not regular but this is a common problem for all the light planes.
When You'll have experience with this plane, You'll be also able to change his "character" just moving the battery to change the COG.
Or programming Your computer radio for different flaps and ailerons configurations, depending from wind and flying phase.
I suggest to buy also a spinner and prop replacemente: the stock one is too delicate and You risk to stop Your flights on the first rock...
It's crash resistant as other EPP planes but has a problem respect the AXN, Bixler and all the other push motor planes: the motor on the nose.
This is the Achilles heel if You have some hard land or if You beat a rock.
But at the same time, the flying characteristics are really better respect a push motor plane and it's really easy to fly.
I think that if You have a grass field to fly it, it is a supreme replacement for AXN.
Not good for FPV: there's space just for a small camera and the front prop doesn't help good video recording.
Upgraded the stock ESC to a Hobby King 30A ESC 3A UBEC and the stock prop n spinner (because the plastic mount for the blade snapped on a landing and was looking for something more durable) to these TGS 10x6F Precision Folding propeller, 45mm Alloy folding Prop Spinner with 3.17/4mm/5mm Adapter. The extra nose weight of the alloy spinner can easily be countered by adjusting the position of your LiPo .It pulls straight vertical no trouble and handles the extra power like a dream. Can only recommend this combo for people looking to get more out of their Walrus.
Be careful to the motor, most of all if You use it full throttle for long time.
Electric motors are really generouses under charge and they easily go over their limits.
They still work for a time, but they becomes hot and they quickly wear out magnets.
So, check the motor's temperature after each fly, most of all during hot seasons.
Just a suggestion, maybe it's everything ok *-)
Yeah of course, gotta take that into account. I wouldn't be boosting it around on full for long periods of time at all, just nice to have the herbs there when ya need it. No problems so far with the motor temps at 20C environment temperature
I've received my Walrus yesterday... The quality of the plane is awesome but I found some issues:
The packaging* the box is the exact size of the plane leaving no room to "play". The box was quite smashed so the tail of the plane, I read many reviews and this happend may times. Internacional shipping is like that, but would be fine with a slightly bigger box.
I can ensure the servos are not tested in the plane. The "red" flap servo was glued inside! When gluing it to the wing, some glue entered the servo (it was not well screwed) so the servo couldn't move. I had to remove it and clean it.
It's not much to worry about, just I let you know so you can improve the product.
I'm looking forward to have it ready for maiden this weekend...
Yesterday, I flew with a RC plane for the first time. I chose Walrus for my first steps. Before this first flight I absolutely reccomend this model. Here is a sum up video of the day. I hope this helps anyone make his choice.
Hi, would someone check their stock Walrus and estimate how many degrees of right thrust and down thrust the stock motor mount has if you are viewing from above the plane or from the front/side of the plane I'm rebuilding the nose after a crash.
In the pilot canopy is very bad. Japan is the country it is today, it was nice weather. The temperature was over 25C.
under the sun was two hours. Light melted in.
I upload a photo. Bad resin. heat-sensitive.
Yes it is. Very easy to fly. The size is also very nice because it's easy to see and much more staple than others small planes. With flaps on you don´*t need a long runway to land it. Recommended mate. Regards
It handles like a dream and with the eliptical dihedrel it self corrects it's axis which is great for newbies. Goes nice and slow and you've got plenty of time to correct any errors or you can throttle down and get some light aerobatics with it.
Only negative I've noticed so far is that the epo around the cockpit is so soft and thin the noise easily breaks at that point from inevitable newbie nose dives potentially causing the motor axis to become off balance.
Hi community, my buddy is considering getting into the hobby but doesn't have a lot of cashflow so I noticed the Walrus looks like it shares much of the airframe of a Bixler 2-style trainer but at a much better price. Would this be a good all-round plane for someone who has never flown and wants a budget bird, but is definitely more than capable enough to quickly learn to fly?
I've got both, the Bixler 2 and the Walrus.
The first one is easy to fly but not so aerobatic as the Walrus, most of all with the original motor.
The Walrus is absolutely more enjoying than the Bixler, but has some limitations:
- has the motor, propeller and spinner in the front part* this is a great position for dynamic reactions, but is the first part that You'll brake if You'll make a bad landing*
- has not so much space for gear, but this is a limit just if You want to do FPV flights in the future (and has the prop in front of the camera).
I use it when I want to enjoy and glide, as the Walrus is definitely more reactive and accurate than the other one.
At the same time, it can be docile, easy and slow, thanks also to the flaps, already installed and active.
If You'll buy it, remember to buy at least one spare prop and spinner from the spare parts list.
And remember to glue the four motor's screws with a medium screw locker: if You don't do it, they'll unscrew in few flights.
What is the best replacement motor for the Walrus? After a crash I must replace the shaft. Impossible to remove from the motor even when removing the mini screw on the motor cage. There was glue on the threads of the mini screw, so maybe the shaft is glued on the motor. So I must replace that motor... that runned really fine in fact !
the L2210-1400 with the stock prop drains too much Ampere for the stock ESC.
Stock prop is 9X6 and stock ESC is 20A.
With a 3S battery and stock prop You'll overload the stock ESC.
You've two options, if You want to keep this motor on You Walrus: change Your prop or change Your ESC (or both).
It seems the preinstalled ESC seems to be the Hobbyking 20A ESC 3A UBEC. My orginal ESC had problems and replaced with this one that works perfectly. There is no label on the original ESC, but both ESCs look the same like when comparing the location of components through the heat shrinks.
Tts wat I thought too but I tried using d manual/programming guide of d hobbyking 20A esc but it doesn't work. The beeps n alerts r different. Anybody had any success programming dis stock esc? Wonder why Hobbyking tech support neva answer any tech questions posted by users....??
Here is a video which is made from me using the walrus from Hobbyking by mounting a Gopro Hero 2 on the fuselage exactly to the CG very easy..! You can see a very beautiful place in Greece and really nice music..! Have a nice watching!
P.S: All the photos are from the air by Walrus...
The box is a bit longer than the fuselage and would hardly fit in a standard suitcase unless you have one of those extra large sportsgear bags* you should carry it as an extra piece of luggage. The wing comes in two halves and is attached by two srews on the fuselage and can therefore be unassembled.
Can someone tell me how big the original box is ?
I want to buy a plane soon when being in Hong Kong, but it (in the original box) will have to fit into my luggage in the airplane.
Other question, once it's assembled for first time, I hope you can disassemble the wing for transportation. Is it two half wings or a full wing ? I still hesitate between this one, the Bixler V2, and the Walrus. I'm rather like a newbie in planes. Thanks in advance for your answers.
The original box has the sizes 1,5m x 0,25m x 0,3m more or less. Yes the wing are in two parts so you can easily carry them. But i don't know if you can put them into your luggage. I am afraid that can be damaged...! Hope i help..
Hi Koniako. back from travel. A short video of my predicament can be seen on Youtube under "walrus esc motor malfunction". Maybe u can make something out of it...
6 thumbs up!
apperance wise it looks amazing, flying wise still not sure, however it looks great.cant wait to get one.

Well conducted three (3) flights today with 1800 and 2200 mAh 3S battery. All went well, very stable as mentioned, easy to solo hand launch, and the motor/prop combination is excellent. Very fast in a dive and low pass. Minimal pitch change nose up with flap deployment, countered with 3 clicks of down trim. Flapped landings are a piece of cake, and sooooo slow. It even has a respectable glide, and a bigger battery not required. The heat sink on the speed controller came off due to running hot, so I will elect to upgrade to something slightly bigger. My review is buy one if only because it looks great, the lovely flight charactaristics are a bonus. A strong 9/10 in my humble opinion, just love it.

I forgot to mention this goes together like a snap, there is no easier assemble to be had, and the wing, tailplane/fin mounts are awesome. HK you have done it again, well done.

The manual COG of 71mm is too far aft, 45mm to 50mm is a better position, with an 1800 to 2200 3s perfect.
