Default Rudder Control Lock

After a suggestion from fellow -14 owner at OSH, I am trying to fashing PVC tubes to hold my rudder pedals firm against wind gusts. No good. The slant of the pedals just pops the device (looks like a PVC 2-tine pitchfork at the moment) up and the rudders move freely.

Any other suggestions for a usable rudder control lock?

I sorta copied this from the one in Van's RV-14, which was made out of wood. The aluminum is the C-01442C spacer used in the canopy frame construction with a hinge bolt at the aft end, The forward ends are rounded and padded to fit the pedal bar. The aft end presses against a piece of thick leather to avoid damaging the carpet. You have to adjust the length to make a tight fit. It's worked well for 4 years with no tendency to slip. Very easy and fast to install/uninstall. You can even reach down and yank it off on the takeoff roll if you forgot to remove it :-)

Here is what Iíve used on all three RVs. The lines are tied (using a bowline knot) to the middle elevator hinges. The elevators are held in the nose up position using the seatbelt looped over the stick.

I shamelessly copied this idea for the -10, should work for the -14:
Take the standard Bogart tow bar; add two tabs facing aft (when on the nose wheel) attached to the pieces on either side of the nose wheel. Put the tow bar into the cockpit, tab end down, handle up. Insert the tabs over the rudder bars. Move handle down, feeding control stick thru the triangular opening, pushing the handle firmly into the seat back. Loop seat belt over handle to keep it in place. Use other seat belt to pull control stick into the V of the tow bar. All three axes are now locked.

Steve and Allan are probably industry leaders. Here are my control surfaces locks. I am parked under the elements for nearly a decade and these held the gusts up to 50 knots.

Here's what I use in my -10; I've seen a couple of -14s, but haven't paid enough attention to the cockpit design to know if it will work in that model.

The PVC portion is a minimal modification from what I received from the original builder when I purchased the A/C--thanks John and Teresa. I slip the short PVC segments over the bottoms of the starboard rudder pedals. The "arm" length was trimmed and the angle adjusted to allow a tight fit with a slight "over center"--when the crutch tip is jammed into the junction of the floor and bulkhead beneath the seat, e.g. the arm slopes up slightly in the direction of the rudder pedals. Note that the arm is offset from center so that the stick itself doesn't interfere with placement. The combination of pressure and rubber crutch tip minimizes slippage risk. I can install or remove while sitting in the cockpit. That locks the rudder, and if I'm just refueling, going to breakfast on a calm morning, or similar, that's all I do besides tiedowns.

If it's windy, or if I'm going to be away from the A/C for any significant period of time, I also secure the elevator and ailerons. Basically, one nylon strap passes through the outboard port-side seatbelt (Hooker) buckle, wraps x 2 around the starboard stick and back. That is repeated for the second strap on the opposite sides, creating an "X" pattern. The styrofoam cylinder (as used for physical therapy, and readily available from Amazon, as are the straps) is placed between the starboard stick and front of the seat before the straps are drawn tight. That leaves the elevator in a very slightly up orientation (it could be changed to slightly down by using a cylinder with a larger diameter). I've left the A/C for multiple days at KWJF (Lancaster, CA) on several occasions. Typical winds are in the 25 knot range there, with higher gusts--no issues.

No risk of departing with the locks installed. You couldn't get in and buckle up with the ailerons/elevator secured, and it would be difficult to taxi without noticing that the rudder pedals can't be moved.

Default Rec antisplat lock

I used the pvc for several years but it would sometimes slip off. Feel Alan Nimmoís device is much more secure and worth the cost.

I use the PVC rudder gust lock and never had a problem. I think the key is that you need to widen the base at the stick end by giving a wider base with the "T" fitting. No chance of it slipping out of position.

I donít have the bogart bar but would consider getting one if it was easy to
Lock all three controls.

Thanks

Did you use a tee with half cut off at the pedal ends and fit to the bottom horizontal bar? That wont slip off. Pictures?
