RE: HB engines??
When I was a teenager (about 1986) I flew Q-500 races with my local club just for fun and bragging rights, nothing real competitive, Everyone in the stock .25 class could run OS .25fp's or the enya or any of the stock engines from STor fox or K&b. Anyway I got this HB.25 in an auction and stuck it on the front of my Scat cat Q-500 racer. MAN! i ran circles around the other guys, won every race I entered. the guys in the club looked at the engine and decided it was ok but theyaskedme to move to the .40 class races. Well I won most of those as well, until guys started showing up with Nelsons and YS engines. Fun while it lasted, and that engine was light and powerful for it's size, probable the nicest engine I have ever run, didn't have to fiddle with it, just gas and go!</p>
