You will need those batteries to be 3 cells. The 900 would be perfect for the following

Motor: Axi 2208/34

Esc: Jeti 8 amp

Never flown one but it will be next on my list

Check out the foam profile kits that are out there (Great Planes Flatouts, Fancy Foam, etc.) Most of them have recommended power setups. Take note of the following specs, and make sure the components you buy meet or exceed those specs:

1) Battery: Number of cells, max constant current (Amps), total capacity (mAh)
2) ESC: Max constant current, max voltage, BEC current rating
3) Motor: Kv rating (get similar rating), max current or power rating, size (get similar size)

If you want to use your existing batt packs, the specs on your packs will determine the max weight of the plane you can fly. Take the nominal voltage of your pack and multiply it by the max constant current rating for your pack. That's your max power in Watts. You typically want at least 10W per oz (for planes under a pound) or 100W per pound (for larger planes, say 2lbs+)) for sport flying, and for 3D you will want up to twice that.

Outrunners have the outer casing that rotates, therefore producing more torque, eliminating the need for a gearbox, which can be noisy and adds weight. Inrunners have higher rpms, and lower torque, therefore making it so that you need to run a gearbox, or use the motor in a faster plane. Inrunners are more for sporty or high speed planes, whereas outrunners are for generally anything that requires a big prop.

IMO, any 12-16oz. foamy is perfect for your lipos.

Just purchased the Aeroworks Extra 260. Built it yesterday and flew it today on the Axi mentioned above along with the Jeti 8 advaced plus and TP 3s910.

The first flight was with the APC 11/3.8 slow fly. Needs a 10/3.8

AUW is 14.0 ounces. Lightest I've flown for a built up profile.

Flew great, a supurb 3D plane. Flies great even without the side force generators.
