Old "new" Webra Bully converted to gas.

Silencer: DA 50 canister on a 22cm long header.
Ignition: RCexl with an unregulated A123 pack.
Fuel: 2% unleaded.
Temp: 10-15°C.
Propeller: APC 18x10 "sport"

Maximum 7800, with a steady idle of 15-1600rpm, after warm-up.

I´m considering trying an APC 16x12 or 14 since the engine is going into an enlarged Hots, and I don´t have much clearence when running 18in props.
