Setup:
Turnigy 2826/6 2200KV
6x4 Diatone Bull Nose
Zippy Compact 3s 2200 mAh 25c
Aerostar 30A Esc 2A Bec. Very good results with a constant value of over 900g of thrust (the peak was slightly under the kilogram).
This will be the setup for my second foam f-22. Also i'll try to do a test with a more powerfull 40c battery.
