If Pierre is still active here, any chance you could repost the pictures on another server, maybe Imgur.com so more RV'ers can benefit from this design?

Pierre's locks are very similar to the ones Mike S. showed in Post #10 in this thread.

Perfect, thank you !

Here is what I built from Pierre's original photos. (WARNING: this link won't last more than a couple months)

You can also make one out of some aluminum like I did many years ago. I know of one person that used reinforced schedule 80 PVC.

They follow the design used in the Diamond DA-40 gust lock system and works well. The best part is that it is impossible to take off with the gust lock system installed. You can't even get in the airplane.









:cool:

Gracias. I built one like that but the problem for me in the RV-8 was you can't remove that type without getting in the plane (or hanging headfirst on your stomach over the side :D ) so once you removed it now you had to climb out to store it away then climb back in. I'm not 20 years old anymore and the hardest part of flying my plane is getting in it ! :):D:):p

Thanks. I got the top of the rudder picture and the yellow one is the aileron, so is the middle black picture the elevator trim tab?

I always have mine hangared but when I fly places for the day I'd like to take something that doesn't weigh a lot or use up a lot of baggage space.

I'm worried those small sizes might dent the aluminum, have you had anything dented with higher winds?

The rudder lock is made from 1/4” steel and the pin from 0.063” steel hinge pin. The aluminium plate is to prevent the legs spreading under load. I have another lock for the other side to spread the load to both rudder stops although I just use one for short term parking.
The elevator/aileron lock is made from 0.118” steel hinge pin which is inserted into holes in the panel flange. The flange holes are small which stops the lock falling to the bottom of the stick. Mine is slightly spring loaded pushing up against the bottom of the securely fixed stick grip. The seat belt is pulled up tight around the stick.
Both these locks are very secure.

I have the same pin for the rudder stop but only on one side and it's thinner wire. Don't have the retainer on the bottom but it has never come out once it's in unless I pull it out.

RV-10 Rudder Lock
 

The picture(s) attached show our approach. This plate has three hoses through the plate, the larger holes are sized so that our tow bar handle can be used to pull the lock into place. Likewise, the tab coming off the bottom fits inside the handle of our tow bar to install the lock. Worst case, you can just push the tail down and install the lock from the ground, or one of the partners in our airplane is tall enough to reach it. The gust locks for all of our surfaces are kept in a red bag, the red bag gets placed over the stick grip when the gust locks are installed as a reminder. This is very light and simple, it locks the surfaces so the control linkages are not worked by the wind.

I used to use the proper LJ control lock strap hooked over the top of a rudder pedal then secured to the control column.:)
I simply use the seat belt on my 8 and two pieces of wood with a bolt and wingnut for the rudder, too easy:)

These light weight control locks will fit into a small Crown Royal bag, and weigh less than a pound. The one with the red hook (from Steve Melton) is the aileron lock. The one with the two black dowels (now yellow) goes on the left elevator counter balance arm, held in place with a bungee. The other two pieces are the rudder lock. They go on either side of the rudder bottom hinge point and must be fit to your airplane for proper length, but when finished, hold the rudder tightly in trail.

If you have a counter balanced rudder, locking the counter balance arm is a better solution. If you have a non-counter-balanced rudder, this option may work for you.

You’ll probably have to spin these pics around to get a proper view. I know there is a fix to this IOS phenomenon, but I haven’t figured it out yet.

Simplest gust lock ever. Just drop from above. Self-adhesive velour inside. Did not test on the field so far. Fits 7,9 and 14. I am 5'8" tall and I can place it onto 7a but 5' girl will definitely need some step stool.

Very cool! Bring it next time you are in neighborhood I will test it for you. Couple days ago we had a winter storm with higher winds. Ripped the windsock off the frame. I was lucky the plane faced the wind :D

wow, it looks as if it bent the pole also and there is some SNOW!

Got solid 4” of snow Steve. On Sept 9th could you believe it? Still snowing. Siberia! :D

I don't know why the pictures loaded up side ways. When looking at the pictures, tilting your head to the left helps.

Here's my super low tech, cheap, and light weight, (12ozs), approach to control locks. The ailerons are just pipe insulation wrapped in duct tape with orange ribbon embedded. They stick up well above the top of the wing making them visible. One pushed/wiggled down on both left and right ailerons do a super job holding the surfaces still.
The tail section was made from some left over aluminum scraps. Stick on padding on the inside protects the paint. The center is wrapped in duct tape with the ribbon also embedded. Rivited on the side is where I slip a 3/8th dowel rod to get it up into place. Cotter pin keeps the rod from going through and holding the ribbon secures it to the stick as it's raised and slipped down the split at the top of the stab. Just enough duct tape around the center to make the slip a snug fit.
The elevator are a couple pieces of wood with the stick on pads for surface protection. A center bungie type line for tension and the ribbon. Stretched and slipped into the left and right elevators, they are very snuggly held in place.
A piece of pipe insulation wrapped in the tape and ribbon attached slips over the pitot tube.
Only thing I don't have figured out is something for the static ports. Still scratching my head on that.
When packing them up, they end up about the size of a grapefruit and slip easily into my little bag.
