To operate, push the right rudder pedal with your size 12 until you get the "ball" in the center, or where ever you want it, then start cranking the turn buckle to tighten the spring (this PULLS the rear pedal forward, and the right rudder forward) until you can remove your size 12 from the front rudder pedal, and maybe tweak it if necessary. I know your thought now is, "suppose I forget it all in the traffic pattern," no problem, the spring might cause a little more pressure to be applied to the right rudder, but it works fine...If you think of it in time, you can reach down and disconnect the spring without even looking. So you don't have rear rudder pedals?..No problem, get a aluminum rod, attach one end to the right rudder pedal right flange, drill a hole in your right side bulk head and install the rod through it, allowing enough length to work back and forth...For a long flight, get the "ball" where you want it, and IN THE FRONT OF THE BULK HEAD, attach a small pair of locking pliers to hold the rudder in place...LAUGH IF YOU WANT, but I used this for years to go to OSH and LCL before installing the rear seat rudder pedals (and never had right leg limp after arriving)...If you forget about it in the traffic pattern, KICK THE "DOG POO" out of the rudders and the pliers will fall off...(provided you didn't crank them too tight!)................Hope this helps someone out there, good luck and .....................CHEERS!!!!...............................Gene Smith. ________________________________ Message 2 _____________________________________ Time: 06:24:11 AM PST US From: Rob Ray Subject: Re: RV4-List: Rudder trim inside the cockpit Jerry, Gene's idea is great but is alot easier than that. All you need is a simple horseshoe shaped piece of .040 aluminum 3" wide. Drill a hole in one side and attach a small piece of mini bungee cord with a hook on one end and attach the cord to the horseshoe. You simply place the "U" in the Horseshoe over the rudder cable (next to your right thigh) with pressure on the rudder inflight with the hook over the edge of the fwd fuselage bulkhead. Release the pressure and voila' the cable pressure over-center moves the U to one side thus holding the cable where you put it. Same principal as a strap for climbing palm trees...:) Very simple, cheap and works. I'll take a picture for you and post it...
