Thanx alot bro...

Getting a ball-head 2,5mm wrench will help a lot!
It's still not easy, but doable.......

I have a 2.5 allen driver but its not a ball tip, ill be sure to hunt one down and give it a go.

I am so used to being able to drop the motor out of my x-ray so quickly i thought there must be an easier / quicker way for the pro4 ...

thanks again

I found that the 2.5mm ball driver is good for tightening the screws and unscrewing them, but to get the screws in initially I prefer to use a normal 2.5mm driver because you can direct the angle of the screw better.

I just ran my Pro 4m last night for its first race and I noticed that the ball cups became very sloppy. I was wondering what some of you other guys were using. I race at RSJ's. I use to use rpm cups on my Losi car but I don't think they will work on the Pro 4 as the ball studs look way bigger than the losi ones.

I have ran mine with the stock ball cups for a few races, a little slop, they are still fine with me. All ball cups wear after a few races, you might just be used to the tight fit of the RPM cups.

I use purple RPM ball cups. Just pinch them on the socket. They will fit tight and be slop free. They will be a tight fit, unless you do this.

To stop the hex-hub binding when tightening up the wheel just remove the shim from behind the pin going into the hex-hub and put one of these shims each side the plastic spacer between the bearings. This stops the two bearings from binding which is what usally happens. Ive had this on my PRO3 & PRO4.

All I do if I have a bit of play in a ball cup is put a piece of plumbers PTFE tape on top of the ball stud (I fold a square piece twice). This does dont bind the ball cup because PTFE tape is slippery and thin.

just use a ball driver you can take off the motor screw on an angle i used to do that with my EVO3 looks like its the same process .

Those are professional setups. We won't see steel outdrives for a while. Come to think of it, we haven't even been given our promised aluminium spool
