I have just bought a Sirio .18 for my revo with the trinity eaxhaust system. I'm in the break in process, but it don't seem that powerful. Is this a good choice that I have made? Is this engine powerful? Is it hard to tune? Please any suggestion would be apreciated. I'm just not really happy with the upgrade.

Excuse me but I bet you that me and the intial poster are the only ones who own a Sirio .18 on this for or we are 2 out of very few. This is an excellent engine and puts out relatively the same power as the O.S. TM. As for hp and pricing they both have 1.9hp and Sirio has higher RPM's. The TM costs $180+, I bought my Sirio for $80 shipped. Be patient! This engine is very easy to tune and make sure you do a carefull heat cycle break in! My engine absolutely screams and i have already proceeded to strip my diff gear because of the power. Compared to the O.S., id say it is 5 times a better deal, similar power, more that 2 times less $$$!!! I am very satisfied with my engine and I hope that this little mill brings as much happiness to you as to me. A+ Tom[>:][8D]
