HawkSky Gyro


Just ordered a HawkSky. I heard a Gyro can be added to the ailerons to increase stabillity. Any model gyro recommended or any howtos?

There are lots of threads on RC Groups that deal with the use of gyros on fixed wing planes. https://www.rcgroups.com/forums/show....php?t=1035605

From what I am led to believe, you want a rate gyro, not a head lock gyro.
I do not know what kind the gyro is that you posted is.

They should say what type they are in the description, so you may have to find the manual online for ones that you are considering purchasing.

I ended up buying the 704, although the head lock would be pretty cool also. From what I understand, if it is initialized properly, it will return the plane to flying horizontally if you let go of the aileron control stick. Someone in another thread said it wouldn't work with the stock rx/tx so I decided to just get the 704 since I know it will work.

It's a rate gyro so it will work fine.

yeah that's the one I ordered. Threw a 1800mAh 15C lipo in the cart to get free shipping.

The 704 gyro seems to be the best one for the Hawk Sky. I put one on my Hawk Sky and it definitely helps flying in wind. My maiden flight was in 15-20mph winds and I quickly lost control of the plane. With a little more experience and the gyro, I can now fly in 20-30 mph winds, though at that speed the stock motor can barely make headway directly into the wind.

Here's a video I found on how to install the gyro in a Hawk Sky:
Hawksky gyro install with Esky 704 gyro (14 min 21 sec)


That's what I did, though ignore the part about the plywood and the special tape. I just hot glued the gyro directly to the foam block, which in turn was glued in right over the wheel well in the back of the nose (make sure not to shove the landing gear into its mount too hard though--once I accidentally shoved it straight through the fuselage and dislodged the foam block with the gyro on it). The video is right, about 30% clockwise turn on the dial should be about right for the stock aileron configuration. I recently doubled the size of my ailerons and noticed the gyro seemed to be overcompensating because the plane was bouncing around constantly in any wind. Today I tried flying with the dial around 15%, and even though winds were much calmer, it produced a noticeably smoother effect in my on board video footage.

Regarding a rate gyro in a Hawk Sky, the 704 will fit on the bulkhead below the hatch
magnet and not interfere with the hatch fit. Will the gyro performance be affected by the
gyro being close to the receiver and the hatch magnet? The gyro functions in that position
but unsure how well it will work in flight. Will appreciate all replies and input.

Thanks, from Brookings Oregon

Personally I prefer the setup shown in the video I posted mounting the gyro on a foam block on the little ridge above the landing gear mount. It's less in the way there, and it's also perfectly vertical that way while if it was on that bulkhead it would be slightly slanted. I doubt it would affected by the receiver no matter where you put it, though I have no idea if magnets affect gyros or not. You may just have to test it and see.
