I have had fast planes before, I just lost my 2/46 duellist.

I did not know the DD had no gear.... I wasn't able to find a pic of it. Thank you for the info, I'll look at more of a Q500 type plane or stuff a Jett 90 in by old curare.

I checked out the Jett site...holy crap, those are some fine looking engines. Are the performance and reliability as great as I have heard? Not a single person in my club (that I have talked to) has any real experience with Jett.

For the same money, a YS 1.1 could swing a lot more prop, but is a 4-stroke just not a good speed ingine? I don't hear anyone talking about using them in speed planes...

Makes sense, rather heavy and low rpm. My Mustang with saito 100 pushes 100mph with the right prop and fuel.

Thanks again for the help, I love this forum....so much info from experienced pilots.
