have a revo 2.5,currently has a picco.21maxx in it[],just never really liked this little engine,i have on my shelf an o.s18tm and a picco.26 maxx,both sitting on revo mounts. i just cant decide what is going to give me less problems in the long run.this is a stock revo aside from the 21 thats in it,so i would like to hear from anyone that runs the revo with any of these combos,and what drive train hop ups would make this truck a little tougher.

So far I love my os 18tm...WAY nicer to tune and run than my old 3.3.

if u would put the .26 max in u may need to upgrade the tranny to handle the power. but it depends u drive. sum ppl would upgrade it.

i run t-maxxs with the o.s18 and the picco 26,i love both of these engines,i am very heavy on the throttle,i did a little more research on dropping the .26 in,seems like some people have had issues with the engine mount,so it looks like O.S.18tm it is

well,dropped the O,S18 in the revo,love it,itt'll carry the front wheels,fast as sh@t,and to beat all i did not lose that much run time per tank.i tried to put the picco 26 in just to many mods to do to make it right(wife cut my r/c allowance[])plus i would like to research,pipes,foc.and the mount seemed sloppy,drivetrain upgrades,i'm very happy with it for now,

Glad to hear man. We have a 2.5 revo with a 3.3 in it and it's a blast to drive. I love my picco .26 but it's way too much power for my preferences.
