I am going to add above the wing battery mounts ( Velcro ) and double check latest planes.
The most noticable change is back to the old standard - lower wing loading .
In the following pics - the two models are identical in size but one is 3mm and the other is 6mm Depron (both braced with small cf rods )
(both with the new Hacker outrunners -small 34 and large 22L)
The white one with red yellow blue tip splashes is 7.7 AUW
The red black white one will be 11 -12 ozs.
We found that the light one at 300 squares (wl of 3.8 ozs /sq ft!) beats everything we have tried so far -so I duplicated it except for weight and power .
I expect to see faster flying - but I want to see what else really changes -good or bad.
This business of whacking things from foam then test flying the same / next day - is incredible.
I have learned more with this stuff in a few months than I could have done in a year with the gas stuff.
One noticable thing is getting aileron diff correct - the single servo for aileron -can easily produce too much down to up aileron and the rollers try to pull to the down aileron side!
weird.
