So far my luck with the gears have been fine but I've only spun it up on the bench a few times so far. I will keep you posted although your more likely to get your in the air before I do.

I like that mod you made to the gear box for the bell crank. I haven't decided how I'm going to control the tail yet. I might use a servo mounted in the tail to avoid the use of a bell crank or I might use some flexible "Golden Rod" mounted in some brass tubing for support. But after seeing your mod I might go with a traditional push rod.

Thanks Andrew. IMHO the size of the TR disc in this heli is a bit on the big side for goldenrod. Plus, you probably don't want any more weight that far back in the fuse. You can do it, but it will take a lot more ballast in the nose.

One word .. OK maybe two .. Flex Drive. I know some hate them but they are easy to set up and WORK!! All of my Large Turbine and Gasser scale helicopters use a Flex Drive!

I agree Tim, your flex drives do work very nicely. I just decided that I was going to build this one the way vario designed it...

So, I need to cut open a section of the tail boom for access to the 47 degree GB. Then I need to mold a new section to replace the one that I'm cutting out. I made a paper template, then traced it out on the boom. Then I taped down some release ply and laid 4 layers of 6oz glass cloth over it. Popped it off the TB and what I have is a female mold for the replacement part.
