Volfy,
I also plan to just fly mine around for fun that's what the plane was made for basically. I'm still learning a lot and can only do the norm of flying around, going vertical, loops, and rolls so far. I realize it's not a 3-D plane as mentioned above. What I'm also planning ahead for the future is buying an engine that I will use in the future for a 3-D plane when I think the time is right. I want to familiarize myself with the bigger engines, make sure the engine is dependable, and broke in all the way. Other than having fun flying the plane around, I think it would make an excellent engine experiment/breaking in plane. So, over the MDS, or the Super Tigre, which has more power ?

Razor,
Why do you not recommend the MVVS engines ? Too over kill ? Well, I'm hoping if I do choose to go with the 90, or 77 it will at least idle down enough to stop the plane when I land it...hee hee heee.

Thanks guys, for the replies, any others out there ?
Dennis
