what type shaft on the motor does the mtx 3 need?
Gentleman, please don't worry about options for the car at this stage. You need to spend time studying your instructions and very carefully build the car as best you can. Do not worry about hop ups to make you faster as the only thing that will help is a sh*t load of worn out tyres. A fast car is about 80% tyre, get this one thing right and you will start finding the needed items but remember your car is very good and fast out of the box.
Very few things have let me down over the past 18 months running the MTX but the following can fail.
The front dog bones bind a little at full steering and will pop out if you hit something mid corner.
Eventually the plastic wheel hexes will rub on the bearing especially if you lose a wheel and start putting extra effort into doing the nuts up tight.
Wire belt tensioners are just pox.
The two speed shoes will fail at some point, the grub screw that sets the gap can strip. This happens after the cam has a nice little groove worn into it. It's not a big deal you just need to keep an eye on it.
When you get this thing on the track go as slow as you need to make sure you stay on the track. If you need to be marshalled often you will not win.
