I can asure you the conrod has the same strength as b4, even on a dummy prop load i hav spun the engine to 38k rpm's for 45sec with out a single loss, allthough i did see quite a bit more stress on the piston skirt B4 i trimed it up.

Your talking about KNIFE edgeing the crank, yes that help's with oil slosh and it might verry well help us here,Let me draw up a plan and order a new batch of crank's and try this once more shall we
BTW Here is my 3 .18 beauty's
I will be building up the OS engine there by request of a certain some one on this forum I need to find a good carb for it as that HPI is under sized for any real power.

Ok guy's i just tore my tranny down and found a piece of trash stuck in the 2nd gear clutch, could be why my shift's were wacked out..any idea's for preventing this?

Drive in a cleaner parking lot.
Actualy, that was a serious comment. Getting debris inside the 2 speed is pretty rare. I wouldn't worry unless it starts happening regularly.

There might be a lexan cover available for the NMT that would fit since it shares the same drive train.
