thanks i did the dont ever do it the other day.

i have a ).S. .30 EB modded engine and i put a CB on it and accidentally used an aluminum screw and broke the head off in the crank i got the screw off but damaged the threads then i tried to re-tap it and the tap broke off in it

so i just cut the crank down and used this http://www2.towerhobbies.com/cgi-bin...?&I=LXBZT0&P=7

i know it will not be as "true" as the crank, but it will work fine and not cost me to have a new crank put in, especially since the engine was brand new never even had a glow pug in it when i did it
