Using a short piece of fuel hose over a nylon clevis gives you false security. Yes, false security. Ever see a fuel hose, when used in normal fuel service, split at the end? If you have not you have not been flying much. When the short piece of hose is slipped over the clevis it is stretched 300% or 400% more than when the fuel hose is used on a fuel tank. The hose eventually splits on a fuel tank. When overstretched on a clevis it will not split?????? I lost two planes because I used nylon clevisis on the elevator, as the kit instructions directed. Now I put a Z bend on one end of the control rod, and a threaded Sullivan metal clevis, with locking clip, on the other end of the rod. This clevis cost a lot, close to $1.00 each. In the end it may be the lowest cost clevis there is since you can transfer it from plane to plane. You can purchase extral locking clips if you need them. At the throttle I still use a nylon clevis to prevent metal-to-metal contact. I change out this clevis occasionally. I try to eliminate problems. As a result all my crashes seem to be pilot error.
