If you mean the one like this
http://www2.towerhobbies.com/cgi-bin...&I=LXHDJ2&P=ML I've got it installed and it works out well for me.
sounds like you've tried quite a few different lubes. I would be interested to know which one works the best, vs how much dirt it attracts, and how often you have to relube it to have it working like it should.
The one I seen is from Scott Helmann, Northern Lights Electronics it looks to be the same idea a little more expensive. I'll let you know on the lube. I'll pay more attention to how long each one lasts and how well they work but I haven't noticed any attracting dirt. I tend to over lube puttting some oil on as many areas I can with the canopy off after every few flights or everywhere when rebuilding my heli after a crash whichever comes first. Rick
