Default Smaller engines

Ya know I tried something different. I took the G3.0 (.18) outta my fireStorm and replaced it with a Hobao Hyper .12 engine. This engine speeds the truggy along just as fast as the .18. Wierd? I have the same gearing as before and the .12 is not quite leaned out yet (still running it in). I guess you don't need to use big block engines to have performance. I have obviously doubled my run time as well. The way the engine performs, I might not lean it out any more. I just can't believe the .12 is giving similar performance as the .18. The only discernible change is the holeshot, it isn't quite as quick but for bashing who cares.

Most of those kind of engines have arround the same RPM range so yes, no more speed. But you will have more torque which you can use with a different gearing to gain more speed.
