Need help picking plane for my power system
I have a Rimfire 22m-1000 GPMG4500 motor and a Electrifly BL-8 ESC and several Futaba micro servos.
What plane would do 3d with this system.
I'm new to electric's so need help.
Thanks

Rimfire 22m-1000
Max Constant Current 11A
Max Surge 15A
Voltage range 7.2-12v
Assuming 11v @ 15A surge and 11v @ 11v constant, that puts you in the 121-166watt range.
That would be good for 3D performance on a one pound plane or aerobatic performance on a 1.1-1.4 lb plane, or trainer like performance on a 1.5-1.6lb plane.
A 1600mAh 20C 3S pack through a 1800mAh 20C pack would be seeing only 50% of battery capacity at any point, though you may also be able to get away with a 1100mAh+ pack at higher "C" draw.
A 10x4.7 prop is what I would use given the specs.
So any plane that can use the above or has an all up weight in that range will do fine.
From there it is all your choice.
A full body foamy would be squarely in the target range.

RE: Need help picking plane for my power system
AUW is normally stated for the plane with all electronics installed.
Vendors tend to be a bit optimistic in their estimates.
Assume that you'll end up with a plane that has an AUW that is about 5-15% heavier than what the vendor tells you.
I would shoot for a foamy around 1lb or so.
