Linear throttle curve for Mamba Max

[DrKnow65]

I thought about an eagletree but then I figured there were so many variables.

I suppose if I used an eagletree (throttle signal, amps, and RPM) with a constant load (say a propeller) on a bench it would get me the info needed, but then how to use the numbers to figure out what the curve needs to be?

Is a propeller a constant enough load? (I would think it spins very easily until it has a enough rpm to to have a little pressure forming) Mabey a brushed motor shaft to shaft with the brushless would be a better load?

The major fault at this point is not having an eagletree :) But christmas is on the way, and I've already used the B-Day excuse to pick up a Dark Impact (Dec9th)
