Not exactly the same, but I've got a Sig Wonder (~37" wing, 338sq in, ~39oz AUW) that I converted to electric and it flys great. Here's what I've got in it:

Mega ACn 16/15/4
Castle Phoenix 25
APC 7x6E prop
7 Sanyo 1700 sub-c
Pulls about 25amps for about 175W of power.

I generally fly it for 6.5 min and usually have 1-2 minutes of full throttle reserve.

I'd say the amount of power provided by that setup would be about right for that plane, but it would probably be a bit heavy. In that case I'd probably look at going with LiPo batteries to lighten it.

Yup, those big battery pack weigh alot, I'll go with Li-Po's for sure.

Yeah, I'm planning on switching to Lipos sometime, I'm guessing that with the weight reduction I'd get unlimited vertical.

Here are a few pics of my 43" HOB P-51.
Power is:
AXI 2808/24
Jeti 18 Amp controller
Aeronaut 10 x 6 folding prop
Apogee 3s2p 1660 mAh Lipo
AUW is 28 oz.
This plane is very fast, and with full throttle for most of the flight it will fly for at least 10 to 12 minutes, 18 to 20 with some throttle management. It will do fantastic big loops, and with a lower pitch prop would have unlimited vertical. The motor never gets warm, and the batteries are warm but not hot after long flights.

On the kit, they had a light ply spinner ring for the nose. I used it for a template and cut the middle out of the firewall, which was 3/16. I found the center of this piece and drilled a hole for the prop shaft. Then drill your screw holes, and cooling holes. Don't forget the cooling holes, they are essential for an outrunner! Then I mounted this motor mount in place of the spinner ring, and used strips of 3/4 oz fiberglass about a half inch wide by an inch and a half long and some CA to reinforce the joint. It works great.

Good Luck,
Darrell

Is this the 1/12 scale combat plane? Did you increase the wingspan? How many channels are you using? I just got one at auction with an OS FP15 and AET on three channels. What performance should I expect?

Thanks.
