Traxxas TRX 3.3 Rear Exhaust IPS Shaft
This is a great engine .The break in was a breeze. Its very hard to tune though I had a rb .23 on my T maxx before this . and the tuning is way different instead of finding a great tune like hour s on a clock I had to do it by like min. maybe like 1/32 turn at the high speed needle at a time . If not you will be fighting the tune tell the cows come home. After 2 days of tuning and a 1/4 of a gallon later I have a great tune and I very pleased. If anything its got more power off the line then my .23 ever did.... I order this along with 2 gallons of nitro and a clutch bell and it all got here all atone time 7 days after ordering thats one week sooner then my lhs could have got it ordered for me at half the price.

If a 3.3 did not last past 2 gallons then it was probably run lean alot,or not taken care of,i have had mine for 3.5 gallons now and it is still strong,great motor for nitro rusty,polish the ports and get an ercm pipe to get the most out of them,do not try to fang port this motor,it will hurt bottom end,runs great ,idles all day!

Makes great power for a small rtr engine, mine didnt last very long (less than 2 gallons), but It could very well be a fluke that it broke so soon. It tuned very easy and was a breeze to break in, so all in all not a bad engine.
