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.
