Posted: Fri Apr 29, 2011 5:31 am Post subject: Rudder gust lock

I am trying to figure out how to create a rudder  gust lock that is on the rudder, not the pedals. I would rather control the  movement at the source rather than 20 feet away at the pedals. My RV8 has a 1/8  inch thick angle longeron that runs aft at the same height as the rudder horn,  to which you mount the external rudder stops. A couple of U shaped pieces of  stainless rod connecting the horn to the stops acts as a ground lock. The  problem with the 10 is there is no longeron down by the rudder horn to mount a  similar type of bracket. I could make a bracket that mounts through the skin and  into the aft bulkhead of the tailcone at the proper height to mate up to the  horn, but I would like to hear if anyone else has used a similar approach, and  could send me a picture of the  results.

two alumium angles (1/8") 24" long); padded with  foam (attach foam with RTV) single long bolt thru the center of each angle;  paint RED; use wing nut on bolt. This will securely lock rudder  when inserted at/around the lower hinge.

  

 If desired make a smaller one for the aileron  and/or elevator.

  

 I use the belts for control lock, except rudder,  for short periods; otherwise I use individual control locks on each  surface.

  

 light weight but very secure.

Thanks Sean!

OK, on all my other RV's we built gust locks that "dropped" down instead of the way this one is done with one down leg & one leg going up. This was a test unit that worked well so I moved on to other items on "the list". At some point we may fabricate a new unit that just "drops" into place. There is no benefit to the one up one down design. Regardless it works GREAT in either configuration but the drop into place design has gravity working for you and is a touch easier to install.

I did something similar to Robin, but with the ' drop down' . One     word of caution, when I initially installed the gust lock, I     installed it only on one side, and I did not put 'retainer     pins/clips' to hold in place, During a trip, we experienced some     extremely strong winds one evening  (40-50 mph gusts) and with the     drop down retainer 'crept' upward bit by bit until it allowed some     movement in the rudder, and then it progressively crept up until the     movement was large enough to pull the attachment bracket off the     plane.

     The solution for me, was to replicate the gust lock on 'Both' sides     of the rudder, and to add retaining clips to the drop in brackets     that do not allow for any 'creep'. The retainers are just some 3/16"     ss rod bent in a wide "U" and drilled for some retaining clips which     are wired together ( so as not to loose them) with a Remove before     Flight flag. It's rock solid now and haven't had any subsequent     issues.

     

     Attached is an early picture before I added the other side and     snugged up the retaining pins.

Group,  



Could the angle be mounted on the inside of the fuselage skin with a slit in the skin for the tab to stick out the side...structurally speaking? 



Thanks!



Jim

Thanks guys for the response. Robin's method is  just the ticket, however I'm not sure how much of the tailcone structure I need  to pick up, so I don't damage anything in winds like we had all day long  yesterday, here in Vegas. If I was building the tailcone now, and things were  accessible, I would put in some serious reinforcement to carry the load, but now  as an afterthought, I think an external bracket could be made that goes forward  and bolts to the little stiffener that attaches to the aft bulkhead. The  bracket could then go down to line up with the horn, and catch a couple of  inches of the aft bulkhead along the way. Or maybe  just one that runs up  and down the bulkhead a few inches is strong enough? A bracket on both sides  with retaining clips is also a good idea.
