So far it's great.. With a little preheat it fired right up, no issues in the first 10 tanks. Easy to tune, good idle, producing great power which will only get better....

Awsome. Thinking about getting one. Prob going on a Revo.

nice, how does it run.

 

[Ckeithnitro]

Runs great.. Holds a nice tune.. Doesn't have the torque of my picco .26 reddot tho..

I'm working on a project and I need someone to tell me the outer diameter of the rear exhaust port on the actual casing of the engine. Do you think you could do that for me? Or anybody with an os21tm for that matter.

 

[Ckeithnitro]

It's 3mm bigger in Dia... Than the 3.3 exhaust port...
