May I ask a question to the guys running this new engine, I'm building a 1/5 scale F7F Tigercat and am considering running 2 of these radials. My question is will they be enough power? My plane will probably weight in the 50-60 pound range, hopefully less but it's to early to tell. I'm shooting for 50 RTF. Of the few tigercats I've seen actually completed the engines used range from Da50's to G62's and even DLE 111's which is WAY overkill. Any info would be much appreciated.
