Webra 91 P5, comes with unused Factory Pump never seen fuel, spare Piston Ring for a future freshen up, extra head shims.
This thing is a beast, it’s the most powerful 60-91 engine I've ever experienced, it’s done about 30 mins test bench time, never flown.
it turns a 12x10 APC at 12600rpm on 10% Nitro.
Mounting dimensions are same as OS, 52mm x 25mm engine mount 42mm muffler bolt spacing.
Cheers
Greg
