RE: Lightning Build
Under 11 lbs - EZ.
I have built stuff using ZDZ40 -well under 11 lbs
The BIG problem in using gassers is was and will still be the power pulses inherant in the rpm band used
Good balsa construction is the best forsoaking up th pulses (motor mounts will NOT fix this basic condition-just soften the condition some)
So I am doing - again a design using balsa /spruce -
I do have carbon fibre but basics will be wood.
