PeterF Posted November 21, 2023 Share Posted November 21, 2023 I have an 1/4 scale 88" span moth that is electric and very scale like, a bit larger than your but should provide some guidance. For things like loops it definitely needs a shallow full power dive first and happily flies for 15 minutes if I do not do too many aerobatics. Flying weight 18 lbs 2 oz inc batteries Motor Hyperion ZS4035-10 Kv = 354 (discontinued) 100A Hobbywing platinum ESC 2 x 6S Overlander 3900mAh Supersport batteries in parallel giving 7,800mAh @ 6S 18 x 10 wooden Falcon prop (scale diameter) With full batteries the set up runs at 6,400rpm and draws 1700W (81A @ 21V) This is about 95W/lb which is just right for scale like flight.
