    Hymax Motors

    Would a Hymax CR3516 contra rotating motor be the equivalent 46 size glow engine?

    RE: Hymax Motors

    Perhaps. What are you trying to use it for?

    The proper way to size a motor to an electric plane is by watts per pound. So if you have a plane that you expect to be 6 pounds all up flying weight then a 600 watt motor would give you 100 watts/pound.

    RE: Hymax Motors

    Thank you for the reference. I had in mind a pusher delta winged plane about 450 sqin wing area, 6lb weight. It seems I should be OK if I stay below 8lb. Ill use your reference again to select battery, ESC, prop etc. Thanks again.

    If you are coming from the glow world, I would recommend you stay above 100 watts/pound as that is the kind of power set-up a glow guy would expect.  At 150 watts/pound most aircraft can hover

    Electric slow fly can go down as low as 50 watts/pound and fly just fine.

    http://www.maxxprod.com/pdf/CR3516.pdf.... this document suggests that this motor is only the equivalent of a .30 engine. Reading the specs it seems that 35A/motor on 3s might be getting you 700W max. A decent .46 equates to around 900W.
