I hope so! I thank it may be broke in. I traded two 'cat's' and a airplane for it! LOL. The cat's where tossed out at our flying feald and we can not have pet's , BUT! We could leave them there to dye, They where about 10 weeks old. What kind of 'BUTT HOLE' could do that to these baby? So we wrought them home and a buddy of mine has a cat sanctuary and he took them and there in a good loving home now! and I was telling him about needing an engine, He gave the engine and said that he has had it from new and it looked new. Nice finish! Theres a date on the box that shows it to be about 30 yr's old and so clean that I know that it don't have munch run time. He can not remember when he ran it last time and said that I will be disappointed in the performence. I told him that I was putting it in a Art Scholl's Chipmunk and if I wonted to 3D that I would fly my aeroworks 540T It's 35% and a LOT OF FUN! My wife is building a Canadian Chip-trainer and it's bigger then mine, @ 81in. mine is 71in. A buddy of mine has an 125 in a plane that World Engines built for the 125 and he said that IT FLU! That was the only thang nice he said about it! I like old stuff and if it will not fly it, I'm scaling up a Sr kadet to 80in and I will put it in it. I appreciate the come back and will post the out come. Thanks. ':~) P.S. I'm from TEXAS, Dallas/ft.worth. I live in Little Rock, Ar now! "GO PIG SOOOOOOOIE-UH-LONG HORNS" LOL!
