I was just able to check on the motor, I'm running the A40-12s on a 15x8 prop. I haven't checked watts but I wouwld imagine somewhere over 1200 watts. Its great power for me up in Salt Lake City, which the Elevation is about 4500msl.
You may have to come back on the prop a bit down in lower elevations.
I also have another 59 setup on 4s and its running the A40-10s. I have it on the same prop and it flies just as good. It was basically because I have a bunch of 5s packs that I went with the 12s. If you have a lot of 4s setups for your planes to run 8s on the bigger stuff I think you will be happy with 4s.
Once I get the Orange 59" back from Mark Leseberg I'll measure the CG and give it to you. This airframe is really happy with running a bit more forward CG and still 3d's extremely well. It tracks amazingly well, probably the best tracking small plane I have flown. I was actually out practicing a ton of IMAC with it before the weather got nasty.
