Stryker control loss at speed????

OK I built a stryker from spare parts I purchased from Horizon Hobby.

I didn't want the stock paint job and I put in my own electronics.

With my latest setup every thing works fine except when I am firewalled straight and level the controls are ineffective…
It’s not radio loss because when I slow down I have control again.
And the control comes back proportionally with airspeed reduction.
I found this out by pointing it straight up, full throttle and it does stay in control.

Two things I suspect, elevon flex, but there stiff??
Or servo stall

Would love for another opinion, or confirmation

Here is the setup

DX7 for control

2 HS 56 servos
Wrong they are hs82


power....
Of course it's HK stuff

Turnigy 2836 Brushless EDF Motor 3200kv

70 amp speed control (a little over kill)

3amp turnigy BEC

4 cell 35c 2200 mah battery

APC 5 x5 prop.

Runs exceptionally cool…and fast
Thanks
Dave

Agreed. Get servos with a higher torque and you'll probably be fine.

Nope they are HS 82

Nope they are HS 82 and I was below 100mph.
now my eye goes toward the BEC, It is a 3 amp unit.
