Sorry about your AMD Hawk.
The Fox Hawk has a very good mechanism with mechanical advantage working in your favour.
I do not believe this issue will show it's self so badly as it does on others.
I have an 8kilo digital on mine and during the flight no issues were apparent with the tail. The crash was not caused by any issue with the plane that I can find.
Now...no more work done recently...sorry...University and other issues keep getting in the way[

]
However, more will follow soon once i return from Bickley jets this weekend.
I do have some news, hot of the press.
1) The new wing has flown, it was very successful and the mould is being made. I expect some pictures soon.
2) An electric version with the current wing has just flown very successfully. Very fast apparently and a perfect flight.
Video and pics of this will be posted soon.
Should be posting Monday or maybe Sunday if lucky.
