trx 3.3 or OS .21 tm for revo nitro?
Hello friends
I see that you know well the engine 3.3
I have a Revo nitro, I already replace bearings several times.
I ask your help
It is better to change the original bearings by Ceramic bearings, or rather change the engine trx 3.3 for OS?
I think switching to OS engine .21Tm
I do not want more power or more speed, I want more engine life time.
I want to continue using EZ Start, I do not like recoil.
