you then need to get in touch with my god friend and mentor Darrell Sprayberry. He seems to have mastered the electrics and what makes them tick. he has a 1/4 scale jetranger that is electric powered.at about 36 lbs, it flies for well over 15 maybe 20 mins or so. he runs it on 12S lipos.
Thanks Emile. that is better than 8-12 minutes. Tell him to get in touch with me if he has a secret to powering one for 90 minutes! As near as Ican tell, I would need a loooot of batteries in parallel.
