Default RE: Purple Brushless Electric Ultimate BiPe

I have an E-flite 400 on a E-Flite Ultimate FX foamy. It is just about the equivalent of the motor I am using on my NP BiPE, hence my results. I believe the A20-30L is slightly more powerful... but not by much if so.

The 10x7 may be too much prop for this motor and the NP Ultimate... however it's hard to tell.

Your "cheap" motor may be capable of handling the additional load, it depends upon the number of windings and the wire used, etc.
On the other hand I'll bet it will be anemic with the 10x7E prop.

I would suggest something a little smaller or with less pitch... though you have nothing to loose if you install the prop and run a test.

I doubt that you'll blow the ESC with your motor and that prop... according to most of the calculators you are well BELOW the range of the ESC no matter what.

Hold the plane and run it up full throttle with the plane held straight up.

Does it feel like motor is capable of pulling the plane straight up? Can you practically let go of the plane?

If so the prop should be fairly good with your combo.

If you get less than this much output (as I do) how much less?

In my case it is as if the motor can ALMOST lift the plane, but not quite.
