Randall,
Yap, even though these days I barely have enough time to assemble ARFs, the builder in me just won't leave well enough alone. For a while there, I was putting quad flaps on every ARF I touched. I get a kick out of programming my 9C to do all sorts of quad flap mixes (CROW, AIL->FLAP, ELEV->FLAP, etc.) For the price of a couple more servos and a bit more work, they sure are fun. I power my Hobbistar 60 with a Super Tigre .75. I didn't like the shelf paper covering so the first thing I did after I got the kit was the rip it all off and recover with Monocote. The wadded up ball of shelf paper weighed about a lbs!

By the time I got to the Spacewalker, I was trying very hard not to go nuts with the mods. Still, I did away with the wing-mounted wire gear and bolted a set of GP 1/4 Giles gears. I also replaced the tailwheel with a Ohio Superstar unit and mounted dual elevator servos under the stabs. G23 is the latest choice of power plant. Here's a pic of the progress so far.

I'm a member of both Fort Bend RC Club and Southwest RC Club. FBRC has by far the better field, but SWRC is closer to home and much less crowded on weekends. Of the fields you mentioned, I've only been to Scobee, but even that's more than an hour drive.
