So I'm looking at buying a Revo 3.3 roller.
I want to put in a big block I had an OS .21 in a T-maxx pretty much a direct replacment.
I've read so many threads but I havn't got a clear head on the conversion.
How much is involved into getting an OS.28 into a Revo? motor mount, exhaust, clutch???
Or does it require many modifications the extra power from a .28 is not worth the direct drop in of the .21, or is the .21 even a direct drop in on the Revo??
Thanks for any help.
