Definitely use the p-mix. The elevator surfaces are *large* on this plane - any out-of-sync motion at high rates is definitely noticeable.

Its also a good idea to twist the servo leads - especially the three running to the tail. I noticed a little jittering in mine during the initial range tests; this cleared up after I twisted the leads.

Really fast servos are a good idea. I'm using old-version FMA coreless servos on all surfaces... 100+ oz-in of torque and 0.12 transit times, and beat the Hell out of them



(doing a couple of KE -> KE snaps in a row with 3D rates on will do this.)
