Quality, performance, power much better than OE. Easy tune. Does not overpower but enhances and potentiates the overall driving experience on the Revo. Included exhaust manifold and reuse of stock (or aftermarket) clutch assembly make for a easy upgrade. Racing or bashing you can't go wrong with this drop-in engine.
This is the top end motor for Traxxas Revo . An outstanding super heacy duty motor . Easy to adjust and tuned .
just put this in my jato today bought it off ebay and it is really fast has alot more power then the 3.3 and i cant keep it straight down the road i tried 3 different tires and none of them will hook up with this engine
*Excellent Quality Engine!! *Only Produces 1.9 HP. *Expensive Piston and Sleeve *Excellent Carburetor *Runs Better and More HP with 1/8 Muffler *Fit into my REVO w/ No Mods *Super Reliable Highly Recommend This Engine. Pricey but worth it. The 11k Carburetor is Awesome!!! YOU WILL NOT BE DISAPPOINTED
I bought this motor and installed it...I broke it in really slowly and easy...then tuned it in and this engine pushes my revo to its limits , over the limits lot of times.. this engine is very quick and fast..once I got it tuned in I have ran it for 3/4 gallons of fuel and haven't (had) to adjust it any..two times I could tell it needed to be leaned a hour cause of the heat outside..it would have still ran good had I not have tuned it in..never ever have to set Lo speed needle or idle again..it holds its tune as well as a few of my hi end Italian engines bb's also... They cost more than the 3.3 but for the ease of tuning and the tremendous amount of power you gain makes it worth it everytime you pull the trigger..you have no chance of goin wrong..
Most reviewers rate this O.S. .21 TM engine with Revo/Slayer manifold highly, praising its power, easy tuning, carburetor, and fit in Traxxas Revo and Jato models; several note it stays tuned well and is a drop-in upgrade over the 3.3. Some report the engine is expensive, and a few mention tight rear backplate Phillips screws and short throttle linkage requiring adjustment. Front-end grip complaints and one reported break-in failure, which the reviewer attributed to an improperly cut exhaust port, appear as outliers. Ratings are uniformly high apart from that single one-star review.
