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.
Bearing dimmensions - Front: 7*19*6 mm Rear: 10*19*5 mm
I wouldn't recommend it in a tmaxx or a revo, but for a jato or rustler anything small its great.
