Dynamite Mach 2 .19T 5 Port Traxxas Vehicles Replacement Engine
I purchased this engine to replace my TRX2.5R which was toasted having a broken piston skirt. I read all the online reviews available for the Dynamite Mach 2 .19T and we concerned that there were issues with this engine, however the more recent reviews I had read suggested this be a good engine. So to answer the criticisms from the past.

1, the one way bearing doesn't fit correctly - This has been corrected with a new version of the back plate.

2, The bearings are easily destroyed - Time will tell but the information I have seen is that these have been revised.

3, The run in process is hard to do - This is true, I did have to lean the engine out after tank 2 to even get it to start, but over all the process was easy to achieve.

So far after about 10 tanks through I have found that the engine is way too powerful for my 2WD Rustler with road tires on the pavement.

I had to heat the engine with a hair dryer to get it to start on tank 4-9 but since tank 10 it seems better.

Over all for what was $30 more than replacing the piston and sleeve in the TRX2.5 this is a much better option. When I have saved up some more I will be ordering a spare engine to either have as a spare or rock in my Kyosho V-One SIII if I can get it to fit. That thing will be lethal with a high revving engine and its 2 speed transmission!

It looks very much like the manufacturer has listened to the previous criticism and improved this engine.

Ok, after running a gallon through engine, i have run into a serious problem which has dissapointed me alot. The bearings are garbage! The rear bearing tore itself apart and destroyed half my engine and the front bearing leaks like crazy. I never encountered an airleak due to the front bearing but i'm pretty sure if the rear bearing hadn't died and i kept on running the engine, it would have happened. At the end of the day, i had to spend 100 bucks to replace both bearings with better ones, (ceramic bearings are recommened) the piston, sleeve, and underhead. Thanks Dynamite. But, apart from that problem, this engine is fantastic. Once the engine hits the first gallon it runs like a champ. It's got power, speed, economy, rock-solid reliablity and it's a piece of cake to tune. If you get this engine, replace the bearings with ceramic ones before you start it for the first time. It might be a little bit expensive but you'll thank yourself because you'll have so much fun with this engine for a long time.

Bearing dimmensions - Front: 7*19*6 mm Rear: 10*19*5 mm

Very nice engine for the price. Bought this once my 3.3 went bad. Doesn't have as much top end as the 3.3 but only by a little. Great bottom end. Lots of torque.
I wouldn't recommend it in a tmaxx or a revo, but for a jato or rustler anything small its great.
