I run mainly grass. I am going to do the sealing and see what stablend temperatures give me. Is the OS stronger than the 3.3?
Considerably so. Is it worth $140 more than the 3.3? I'm a bit on the fence about that. Considering there aren't really any other "drop-in" options, if you want more power, then you pay $140 more for it.
Or, you figure out an engine/configuration to put an actual big block on the revo, then your probably still in the $260 range the OS costs. That's with a new pipe, side header, traxxas big block kit/engine mount, various low end engines...
When it got up to 60F a week or two ago, I couldn't wait any longer and tried running my 3.3 again with the losi 3.4 carb. Only to have it bind up on me, then the following weekend I ran the 21Tm again and had a good time.The weather has been nuts for the nitro guys. Freezing, then we had a few days at 80 and suddenly it's 40. I just don't want to start when it's below 70.
Now, I'm trying to sort out putting the stock tank back in my savage x as my old OFNA tank is leaking like a sieve. Lost my mounts...
