Thoughts on the best 80cc engine.....
Yeah, I've seen the 3W75i go as well as the ZDZ 80. The 3W is a nice engine but doesn't have the power of the ZDZ. A nice engine for warbirds is the GT-80 because it is very smooth and relatively quiet too. Doesn't make as much thrust as a ZDZ or 3W 75i but is fairly compact and easy to run.
