XY 50cc A-Spec Gas engine
The 50cc A-spec differs from the C-Spec and with most other gas plane engines of the same capacity because of its highly refined head design and casting. The cylinder head of the A-Spec is cast using an extremely accurate process which results in a lighter head with the same cooling efficiency as larger thicker cylinder heads.
XY engines come with a CNC milled crank case and a Walbro (Japanese) carburettor as well as a 2yr warranty on the electronic ignition parts & 12 months on all mechanical parts.

This is not a modified scooter motor. It has been designed purely for R/C large scale aircraft. Unlike most other gas plane engines built in the region, this motor was designed, milled, lathed, forged, cast, tested and assembled with the single goal of providing the best power to weight ratio, needed for big scale R/C planes.
