Thanks guys for all of the great comments, I'm really happy to hear that everyone is enjoying their engines!
RC-ZOMBIE, no worries I plan on making the B5 for quite a while!
nitroxr, thanks for picking up one of our clutches. Just follow the directions that came with it, they are pretty spot on! Gold spring and start flush should put you right in the ballpark. If you make adjustments start with 1/2 turn increments and I'm going to guess that you will not need any more than 1/2 turn in from flush to be set!
stvnmcc, good to hear. Please let me know what you think once you get a chance to run one of our pipes!
