    Converting a MONI motor glider to electric

    Hi Giovanni, I agree a bigger prop at the right RPM is ideal. However I'm presently planning on (2) motors, high reving props (~6K RPM) primarily for availability and cost. Been a while since I posted, got busy at work....need to get a life :) Haven't rebuilt the fixture yet that I broke...

    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...
