RE: convert into electric?
Yeah, that's a great combination as a .46 replacement.
If anything the higher voltages you configured will make a .46 size plane scream due to the light weight and decent power.
It would be akin to putting a .60 engine on a trainer, but without the weight of the motor, just the weight of fuel.
I take it you've done it on your planes, given the specifics you posted.
How's it working for you?
