Steve,
Just having a bit of fun with you..

... As far as servos go, I look for lots of speed and excellent centering. JR certainly offers that, the 3421 digital is awesome. I pretty much run those in my Q40 and FAI planes. In Q500 I stick with the 3121, just because they are every so slightly lighter...
Props and stuff.. I only run the 8.8 x 8.75 and the 8.8 x 9.25 .. In Muncie at the nats, no matter what the weather is.. I run the 9.25.. My motors vary, but not much. The liner may go from 190 to 192, mostly staying at 190.. the total head clearance goes from .010-.012.. mostly staying at .010... sometimes .010 will get the motor hot on the line, especially running the 9.25 prop. So I have Travis choke it.. Plugs, I only run the heavy duty plugs from Shadel...
AND.. I don't think I'm the guy to beat, thanks for the smile though. I think you got about 15 guys accross this country that are super tough in Q500.
