.12 or .15?

Why do so many people opt for .12 engines as opposed to .15 with regards to 1/10 touring cars? Surely a .15 with a tuned pipe is more powerful & will run the car faster, right?

for racing people use .12s to keep legal for racing

.15s are more suited to 1/10 monster and stadium trucks/buggies

Default but its ok to use .15

Hi, thanks for your reply.

Is it ok to use a .15 in a 1/10 touring car just for pleasure, as opposed to keeping them exclusively to monster trucks or buggies? And it will go faster, yes?

I disagree with that statement.......

back to the question..
If you buy a good solid .12 and gear your car correctly and learn how to tune it correctly then it will be plenty fast enough.. bigger isn't always better..

most .12s may be faster than your average .15 simply because to race you need a .12 and a lot of effort is put into making these things fast. there are exceptions. I have the RD logics .12 s3r and it's plenty fast. just got finished breaking it in, and starting tuning with 30% nitro and the thing is VERY VERY fast and strong. of course my last R/C effort was a micro RS4 with a 540 conversion... but the .12 is much faster than my friends RTR .15 equipped /10 sedan (same car)

If you can find a NS15S5 get it. Or a V15 RB.

Default gx-15

Ok, so I have just bought a GX-15 to replace my GX-12 on my car. The chances are that it aint really going to go much faster with the new engine? Also the engine came with a short crankshaft! Could I pull the old one out of the .12 & put it in the .15, due to the length that I need for the clutch.

I bought a tumed pipe & manifold, I should really put that on the .12 if I'm going to stick with it, right? Are tuned pipes made for specific engine sizes? Or could I use the same exhaust on both the 12 & 15?
