Just got my hands on some new beefy motors, T-Motor MN4014-11 KV:330, that I'm going to use instead of my current motors on a Droidworx Y-6 frame. They're supposed to be very efficient and I bought some new Maytech 60Amp SimonK flashed ESCs to go with them. I'm a bit stuck though because the motors are too large for my current titanium motor mounts. I have some larger ones but they're made for the larger booms on a Droidworx Skijib, so I'll have to do some thinking to get these motors on. They will be lifting a 2 axis brushless gimbal for a Canon 5D MKII/III by the way.

You're absolutely right, I do have bigger ones but I've decided it's going to be too much of a headache to get these to fit, which is why I bought those white Avrotos in the other thread. These will go on a Skyjib X8 instead.
