RE: Most powerful 46 size engine ?
Dave, Chris,
With his first post in RCU (Welcome!) IronHands just 'revived' a three year old thread.
I could have told Jim (w8ye) that the OS is NOT the most powerful of the engines listed, being out-revved by the ST GS-45 on virtually any prop, but I didn't...
It would beat the Magnum .46 too.
