I just ordered one on blind faith. We'll not totally blind but there are some good initial results on the FG site. It's a rail mount 20cc with supposedly the performance of a Saito 125 - 2-stroke 120....we'll see about that. They designed the motor to drop into the same mount/space as a 120 glow motor. I paid $270 US for mine but rumor has it they will be less than that once the initial rush on them is over. Here's a video of it flying: http://www.youtube.com/watch?v=svVlezIX0eg made by the company I ordered my engine from.
I'll be putting it into my EE60 3D profile plane as soon as it arrives (end of August hopefully) and will report back on it's performance, etc. The plane now has a Saito 100 in it so I'll have a good comparison between the two motors as far as performance, weight, fuel consumption, etc.
I'd rather see a detailed review of this engine though as I think, if it's as good as it seems, many will be wanting one.
