Backdraft Innovations Phoenix HPA Engine V2/M4

Selling my Backdraft Innovations Pheonix HPA engine for V2 gearboxes. Bought as part of a HPA project that I never got around to. I'm clearing out some stuff so this is up for sale. Has never been opened. Brand new and with a nice discount. Asking for £225 including postage and paypal fees. Open to offers.
