Hey Ron, I was wondering because I just got a pee wee in a group of engines off Ebay . I never had one before and always wanted one as a kid, one of the kids in my 4H club had one on a Goldberg Stuntsman 18 and it flew pretty well, none of us had any understanding of trim or balance back then if they survived the first tankful we considered them good if not they usually got worse after we glued them back together! This Pee Wee needs a new rod and piston assy. It had a big 6-3 prop and spinner assy on it and judging from the firewall still attached to it I think it was used to get an R/C glider up in the air, it musta been working its guts out trying to get it to altitude! I figure about 20 bucks in parts and she should be good as new, and the little bugger is so darn cute, might just hafta get a Swordsman of my own or maybe a Black hawk EZ Trainer to run it on. T.J.
