Was talking about that at the hobby shop. Nice to know it can be done.

It's a little work, but doable!
You have to remove the spur gear to remove the motor and get access to the place you will drill two new holes.
I had a RC4WD 030 motor spacer laying around that I used as a guide to mark the new holes. I flipped it over and held it in place to make two new marks with my reemer. Drilled them and used reemer to widen holes as needed.
Now here is the catch I ran into...
One of the two new holes is directly under the spur gear once you put the spur gear back on. My spur gear was rubbing on it.
I used a washer to raise my spur gear up enough to clear that new motor bolt in the way.
The ECX 050 motor has a long spline so I poked a small hole out the back side of the motor cover with my reemer.
Raising the spur gear solved the motor bolt rubbing on it AND helped it with gear mess on this longer splined motor. The pinion is much higher on this motor because of the longer spine so raising the spur helped.
And finally the motor is not 100% level. The back end of the motor hits the frame and keeps it 1mm upwards. The motor bolts hold it in place just fine. It doesn't move. But the frame is technically in the way. Its hard to see. But the motor is being held up in the back 1mm higher.
I wasn't willing to notch the frame. And it works and looks fine. But thats the skinny of my experience with this change.
Good luck!
