The engine fit right in my Tmaxx 3.3 and fit the ez start system. It was very easy to break in and after some quick tuning rips the entire tank on 30% with no hiccups. The Dynamite .19 has way better low end torque than the 3.3 and runs cooler.

Ok so I’ll start off with the good!It runs great and tunes easily, has a metal body carb and it runs alittle cooler than a traxxas 3.3.The bad is that the starter bearing binds up against the backplate, (you can see where it’s wearing on the plate in picture) you have to have the ez-start screws so loose that it moves around.What’s nuts is that this is the updated backplate that’s supposed to help this issue.Anyways you can shim the bearing more than the one you normally use but you may not be hitting the backplate anymore it’ll just bind up against the plastic cage that the bearing sits in on the ez-start, my backplate is being chewed up from the bearing and I really think this is a big problem, otherwise the engine is ok.Forget about using the traxxas pull start cause it’s worse on it.So now that that’s out of the way I’ll talk about the performance.It runs good and tunes easily, runs alittle cooler and doesn’t make as much power as the traxxas 3.3.If you have a 3.3 and want an engine that tunes better and makes alittle more power without spending an arm and a leg then just buy a O.S. 11k carb for your 3.3It’ll runs awesome and tune very easily and you’ll even make more power.I would stay away from the dynamite engine unless you want to try and figure something out or machine material off of the backplate.

First engine I got would not stay running.Followed most everyone's advice, pre-heat it etc still wouldn't run.Sent back and replaced under warranty by Horizon Hobby.Second engine fired right up although very rich it wanted to stay running.Adjusted hsn/lsn, idled for 5 tanks to break it in.Over 2 gallons later still runs great, rarely needs adjustment and even then only needs very small tweaks.Mine does not have the low end that the 3.3 did but mid range and above are good.I put smaller wheels on my Revo and now this thing rips. got all my low end back and then some.Motor runs around 230ish temp and loves it.Would definitely buy again as my first 3.3 blew up two main bearings in about 1 gallon.

Got it up and running after messing with the carburetor holds tune really well, but after about five fuel tanks, started to lean it out to tune it, and the carb slide gets stuck and it feels like it’s rough bad machining will update if I can get a new carburetor from the manufacturer to try and get this engine running when it did run it seem to be quite powerful

These engines are pretty sweet-once broken in and tuned they ripFor the money you can’t go wrong-20%They run well -33% will test your tuning skill a bit more-….they run as good as they look….

Revised review: Rear pull start bushing is garbage. Wore out in under a gallon, then they sent a replacement, it wore out again in less than a gallon and ruined the engine. Carb also sucks, very finicky. Lesson learned: spend more and get the OS .21!!! and have no issues!!

Used to replace tmaxx stock motor, this one worked great after I broke it in and is definitely faster than the 2.5r engine, easy to tune

The carb setting out of the box wouldn’t even allow it to suck up fuel let alone start, it’s a perfect mount up in a revo 3.3 but idle screw is hard access once everything was figured out and got her broken in this thing is a nice little motor for a replacement, highly recommend at this point for a cheap replacement motor, just check carb settings.

Really happy with this, bought it to replace my Traxxas 3.3 in my revoBroke in using Adam drake method, tunes really well, makes good power. Had to modify the mount to fit, also had to modify the carb horn to fit the throttle linkage by grinding off the ball. Had to modify the rpm sensor to fit by clipping off some plastic. Stock air filter is too big, but if you glue in the supplies exhaust gasket into the rubber intake elbow with rtv, it will fit after with a zip tie making a good seal.You may have to seal the carb pinch bolt and possibly the crank shaft to front bearing, check these spots for air leaks before hand to find out.

I highly recommend getting rid of your 2.5 or 3.3 and replacing it with the Dynamite .19. My T-Maxx actually runs like it should, it idles perfectly and has way more power than the 2.5 it replaced. The Dyanmite .19 has an aluminum carb that holds tunes, unlike the plastic trx carbs. For the price, it's the perfect upgrade for any Traxxas nitro powered rc.

Well I've had this engine on my Revo for about a month or so now and I have already ran about 2 full gallons through it and it's holding up quite well. It definitely has more power than a STOCK 3.3. But I have a T-Maxx 3.3 that I installed a Big Block Carburetor on and a CVEC pipe and the Tmaxx is JUST BARELY faster in a straight line and out of turns. I'm using the stock clutch bell and spur gears on both the Revo with this engine and the T-Maxx with the Modified 3.3.I do have a Buku pipe on the Revo. So the power is also influenced by that pipe I'm sure but I'm happy with the engine. For a little over 100 bucks compared to almost 300 for an O.S. 21TM. This little dynamite just might find it's way on a couple of my 4-Tecs and maybe even an RS4. Don't get me wrong the O.S. engine is FAR superior to this engine but since all of the race circuits in my area no longer allow nitro. I'm back to just bashing and this engine is great for that. As well as the occasional park race between friends.The break in procedure went smoothly after realizing that it was set FAR TOO rich from the factory. I had to lean it out almost a full turn to get it to start and idle correctly. And even with that it still completely SOAKED the rear of my revo during break in with oil and even after performance tuning still saturates the revo with oil. The break in procedure is almost identical to Traxxas's recommended procedure for the 2.5 and 3.3. So since I have that procedure memorized...I just used that. And have had no issues with the engine since break in. The more it gets used and broken in the easier it is to start and tune. Once broken in and tuned correctly this engine will idle all day and then go when you punch it. No hesitation, no bogging or stalling. Just power and fun!!!Don't worry about the two 1 star reviews in any way shape or form. They just aren't familiar with big block style exhaust systems. Personally I'm glad they didn't reuse the bolt on exhaust header from Traxxas. It's more of a pain than its worth in my opinion. It DOES reuse the stock header from your 2.5 or 3.3 powered Traxxas vehicle but instead of using bolts it has an adapter plate so you can run a spring around the front of the block to hold the header on. Mine has NOT leaked once in almost 2 gallons of run time. And I beat the Pi** out of this thing every time I run it.
