Well after breaking my bloody conrod last month on my 7 port just as it ran out of fuel (and 5 minutes after thinking "I'll just run this today and then change the rod before racing tomorrow!!!"and since having some slight tuning problems I decided to give the sleeve a pinch..Job done..back on top form and with the 2072 pipe absolute screamer..around 9 minutes runtime so a bit less than the 2047 but well worth it for the improved bottom end punch..gotta back off the front brake though as stopping fast at the end of the straight I managed to lift the rear wheels with ease and flip the buggy over..and that's in dusty low grip conditions.
I'm really liking the 2072 on the 7 port, but after trying both I think the 3 port R is still better with the 2047..Next race is on the 5th july at a really tight track with the worst rocky ripped up surface..not my favorite venue at all..maybe now I have the car and both motors soeted properly I can get some points this time..
