The cheap metal gear servo is really good, lots of torque but it is kinda slow (what do you expect for the price)
After checking my engine I found that it has poor compression after only one gallon (one UK gallon, 4.55l) It doesn't lock at top dead center any more. Unlike my other engines that have little compression it still starts up fine
Do some engines have less compression than others? I know that the RB engines have really good compression, I tried one in my LHS and it was hard to turn over without a glow plug in (with a pull start!!) Has anyone else found engines that run well with low compression?

teamatlas: when my HB .18 dies I'll probably get a RB .12 because they are one of the few engines that my LHS stocks (oh yeah, and they are powerful) Someone has a RB in his GT and it flies
