Hmmm...interesting. I checked a search and found nine pages of items listed for control hardware. ALL of the major manufacturers of R/C model control hardware (pushrods, links, clevises, etc.) are listed. If you can't find what you want, then you're likely looking for something very specialized and of very limited application.

As far as tailwheels are concerned, again, a search under "tailwheel" brings up two pages of manufacturers of tailwheels and tailwheel mounts, retracts, etc. Again, ALL the major players are represented.

As far as products go, Tower currently hasover 50,000 different items listed on their website.

Tower has multiple ship points. They use the one closest to the buyer, or the one that has product if another location is temporarily out of stock. That prevents holdups if one location is out of stock.
