Re: Converting a MONI motor glider to electric

Just adding some details (.pdf attachment) on my prop/motor combo test stand that I broke. A few mods (and new propellers) and will give it another go :) Will find out if the combo will run for 30-60 minutes at some reasonable power level (3-5 KW?). If so, will get serious and start on the retrofit ...

Re: Converting a MONI motor glider to electric

Nice motor (Emrax 188)! Weighs about the same as 3 of the rotomax 1500's, but it definitely has more than 3x the power. How much do they cost? I'm cheap, think that's why I was thinking 3 big model airplane motors (about $500 each) BTW, watch the weight and balance from the start. If you don't want ...
