Webra 1.60XP -Mixture

[Rcmaster199 at aol.com]

Jerry,

It sounds like a heck of a combo to me. The great thing about this much power 
is that you don't need to run it at full,  even for planes at the upper 
weight limit, making the beastie even stingier. Do you find yourself using more 
than 5/8's throttle?

Matt
