Harry, I am Bob Bellino, I am 69 years young, and have done slots since age of 8 and wish to say thanks for your web site! Have also been in RC for over 40 years, and made the mistake of trying to master helos? Anyway, not to insult you in any way, I have used an lubricate called Tri-Flow-it contains teflon and that helped me to keep tail rotor slide linkages working smoothly, have used this lubricate on some of the slot cars that I have, also, If you are aware of this, great, if not give it a try, thanks again for your really good articles, Bob B.
