Or PM the users named ThunderbirdJunkie or 46u, they are both sponsored by STS. Even if you found the engines on the web, they can help you if you want to know anything about them (hope they don't mind me telling people this! [:-]). No, seriously, 46u is a top guy, he'll help you out with anything you need to know.
NO NO NO, WE CAN'T HAVE THAT!!
Just kidding, and 46u knows more than I do, but we can both answer anybody's questions. outside of that, supertib is the big expert on STS engines though, he's forgotten more about nitro engines in general than I'll ever know
And Jim, are you SURE that yours isn't the uber-tight one? I know mine is tighter than my 21B is...I should blow through more than a few sets of rotostart gears with this sucker during breakin, LOL
OH, and Foxy, we're not sponsored by STS the manufacturer...just the USA's highest volume importer of STS engines. Thanks for the mention though
