Did anyone tried EDF and/or quad motors installed inside the ducts? What should I look for if I want to use EDF? My model's dry weight is around 1300 grams, only with servos installed. So I assume it will be around 1900 grams AUW. I'm using some locally available foam, which I suppose is a little different compared to original FT foam, hence the weight difference. I would really appreciate any help, for both of the situations. Planning to run it on 3, 4 or even 6S. Thanks!
