XRAY - Model racing cars

I had a EB mods motor. Ed mainly concentrates on the crankshaft, which is 90% of the improvement. Heard he Dynos all the mods on a motor to see which mods works the best overall. It was a very reliable mtor, easy to tune, made excellent power. Ed doesent mod a engine unless it is new parts. Ran about 5 gallons thru it before it popped. (rear brg failed)

I haven't bought any of the other 2 you mentioned so I can't comment on those as far as performance and reliability. Next in line that I would try would be a Hot Mods, just due to Jim Hottingers advertised background and from other peoples comments on his engines.

I have heard that RB mods does some good work, but the way and where he decides to do it kinda scares me. Heard stories that he wips the dremel out trackside and starts grinding away, that doesent set to well with me, just my opinion. Obviously you dont have to have hospital conditions to mod a motor, but the whole idea of dirt and grit and possible contaminant.

I have been running a Hot Mod 21-5 for a while now; going on 6 1/2 gallons. I got an EB Mod 21-5 for RCP Finals and the Futaba race, and it is a beast! The Hot Mod is awesome as well, great run times and plenty of power, but the EB Mod seems to have a little more grunt . Both do awesome work.

i have been running Rb mods and they are real nice. I tried one from one of the other modders and it was good but felt it should be more, so i sent it to Rick Brake to look at and i like his mod better.
