According to the Horizon Hobby website, this engine is now in stock. The price seems right, and I am looking at this engine to power a Funtana 90 or Extreme Flight Yak 54.

I would appreciate any hands on experience that anyone has with this engine. I have an OS 91FX, I am hoping for something with a little more power (10,300 on an APC 15 x 4 W, with 10% nitro on the 91FX). I would also like to know if the engine has the mounting dimensions as the 91FX.
