PilotLight,
Thanks for the correction on the gyro operation. Do you know if it is possible to install a HH gyro on an Axe CP without having to upgrade other components as well?

Schoobaka,
I'll dig into my heli-stuff later and post the name of the oil, the key thing is it's plastic compatible.

All the local heli-flyers as well as Finless's (Bob White's) videos say the same thing about ball links. You want smooth link joints with no binding and no slop. So if you start scuffing the flash-line off the plastic ball (male) side of the linkage, use 400 or 600 grit sandpaper and take your time, test fit the link often during the process to keep from over-doing it. Lightly drag your fingernail across where the flashline is/was. When your nail no longer catches on the flashline, and/or there's no bump that you can feel with your nail, stop.

I wouldn't mess with the "female" linkage at all, don't sand it or modify it in any way.

I do know that some oils/lubricants could cause plastic to "break-down/soften". So if the oil/lube you are thinking of using doesn't specifically say "plastic-compatible" on it, dont use it!

After you do this to your Axe, be easy on the sticks because your heli will be noticeably more responsive.
