Geert said:If you want the new motors which are less weight, smoother, and stronger, they require new metal frame arms... sort of. If the new motors are mounted directly onto your existing frame, the motors won't be able to spin because the metal frame of the gimbal contacts the C-clip on the motor... one solution is to use a 1/2" drill to cut away a small circle of metal on the frame arms, which will allow the motor to then freely rotate. If you don't want to do that, then a thin washer can be installed over each motor mounting screw to hold the motor slightly away from the metal frame arm, which also allows the motor to spin freely.
It's sort of a chain-effect, because as soon as you use the new metal frame arms, the top metal plate needs to be changed as well (the x-shaped one)... so essentially, you'd need new motors, new vertical arm, new horizontal arm, new top mounting plate.

Well, for $150+ to upgrade to new design, it doesn't seem to be worth it given my original design RP is working flawlessly. The new components would give me a weight saving, but IMHO, not quite worth the cost. So I think I'll stick with what i have and upgrade only if I crash and damage the RP.

I am curious if Keri is going to offer the third axis upgrade soon and what the cost will be.
