The Saito FA-150B will happily swing an APC 16 x 8 at 10,000 rpm, offering oodles of thrust and torque for power hungry 1/4 scale models. The case dimensions are the same as the Saito FA-120S, but with more than 20% extra displacement to play with, the Saito FA-150B should satisfy even the most demanding of model pilots.
Hi very pleased with saito engine runs well works great in plane has plenty of power thank you Reg
Hope to break it in in next day or so
Great looking lump of engine
Its a replacement for one at least 10 years old that shed teeth on its camshaft causing engine write off. Fitted to Piper 1/4 scale Sig Cub. Often used to tow gliders up to 2 m span. Yet to fly new replacement but it runs fine.
i have purchased these engines but haven;t built the planes as yet they will be fantastic when i eventually fire them up
