I wonder why the Moki 1.35 doesn't seem to make these lists? I have one and am very pleased. I get over 8000 rpm on a Zinger Pro 18 x 8 with 5% nitro. The engine is extraordinarily reliable: I have never landed dead stick. I think it uses 1.1 oz of fuel per minute at full throttle. I saw a post a while back that said an APC 16 x 10 or 11 was used with this engine in someone's pattern plane with good results. They ended the post with why pay $600 for an engine when the Moki is around. Anyone else using the Moki?
