What is the most rugged and strong linkage to use with a servo that controls the nose wheel and rudder? I didn't get a set of plans with my partially built .40 type trainer and I'm trying to take off on somewhat ruff turf. I need a linkage to my nose wheel that can handle some pounding. A diagram with photo's would be appreciated. The company that made the kit, CraftAir, is out of business. I've had to go back to the drawing board twice already because of this. Thanks.
