My buddy's 502 problem........
 

Just a big THANK-U for all of the great input & suggestions on what might be the problem with the motor. The formula...hp vs. speed really helped. He did take it back and the builders jaw just about hit the floor with the results from prop testing it! He admitted that it was alittle over the hill with his formula. :(

He's gonna ck. her over from top-bottom and make'r right! Its just gonna be short summer 4 my friend! hahaha..... :eek:

PS. he didnt :blaster: the builder yet! hahaha
Thanks gang.......john
