Serum, gave it a quick go with some fully charged 3700's, and using a proper seperate reciever pack not the UBEC. Solved the stutter. So its my batteries being a bit lame. Damn NIMH's.

So it could be the ubec as well?

Possibly. I'm ordering a new one with my Mamba, so I'll test that one with the warrior to see if the ubec could be at fault or not. They're that cheap to replace its no big deal really.

Good to hear the problem is addressed then.

Aye, thanks for your suggestions mate.

Not a problem.
