You have only mainly 1 issue, how many cells do you want to fly her on? It will need to be a minimum of 4S and best at 5S. Buying the batts are a long time commitment, you need to know what you want to use them for in the next plane. I say if money is not much of an issue go with a 5S set up. Why?Because a 5S set up will give you crazy power for a 40 sized plane and is enough to give good performance on the new 50-70 sized planes. May not 3D well but will give you very good aerobatic performance for sure. Later when you run them in series into a 10S set up you can fly 72"-80" planes.

Its a pusher with limited ground clearance so you want this baby to scream!For me if I had it my way, I will go with the following:

Motor - DualSky 4260-5 (680 KV), you can get the motor from 2DogRC, do not buy the Turnigy motors if you want to run on really high RPMs they tend to throw magnets.
ESC - Turnigy 80A (HobbyCity) or the DualSky 80A
Batt - Rhino 20C 5S 4,900 mAh (HobbyCity)
Prop - 11x10 (best size for the set up ) or 12x8 to 12x10 (with good throttle management if you use the 12x10, its pushing the motor to its limit)

This set up with give you unlimited vertical for sure. I have run this on a few planes and its awesome. The DualSky motor can take the punishment too.</span></span>
