 Posted: Fri Jun 19, 2020 4:23 pm Post subject: Anti-Splat Gust Lock |
 |
|
Now that my RV-10 has been banished to the outdoors for the foreseeable future I broke down and ordered the gust lock from Anti-splat. It does well with the elevator, fair with the rudders but only adequate with the ailerons. I was wondering what experience anyone has with how much tension to put on the rudder cables? I’ve got it pushed pretty hard and don’t want to overdo it but realize I may need to extend the rod by another hole or two if it want case unnecessary stress.
Thanks,
Marcus

I have no idea how much force exactly I'm pushing the rudder pedals
with when I use my rudder gust lock, but, I push them both with my
feet and then set the lock. When I get out, I can only move the
rudder back and forth maybe an inch or two without it being
real tight. I've had 60+ mph winds cause damage, but all before I
had this good tight rudder gust lock.
I don't think the ailerons need nearly the solid locking that the
very loose rudder does. wrapping a seat belt around the stick
could at least make is slower to move. There are designs that
do lock it in place though.
For the elevators, I do mine with the seat belt, but it's also
connected to the rudder gust lock, so that the elevator is
neutral. It doesn't make sense to do a full forward or full
aft stick to tie up your elevators, because you're just going to
make them much more wind-draggy if they aren't neutral and
be more susceptible to damage, or even lift, if they aren't
close to neutral.
The simple external gust lock made by a strip of aluminum
and a couple of bolts with vinyl covering on them may be
a good aileron gust lock that is simple and light, if you want
an external one. Just make sure to add the remove before
flight streamer to it.

Would you be able to send me a photo of your anti-splat gust lock installed on your -10? I bought one a few years ago and could not make it work on my airplane. When installed, it holds the elevator and ailerons neutral, and of course the rudder pedals are even. The problem on mine, is that the elevator is not truly locked in the neutral position. In other words, with the unit installed, I can pull back on the stick (or walk to the back of the airplane and raise the elevator above neutral) and that pulls the rudder locks off the pedals and now the rudders are unlocked. I have talked to Anti-Splat more than once, but they have not been able to help me. There is no way I would consider the controls to be locked if a gust can pick up the elevator and pull the lock mechanism off.
I know of a couple of others who have had this experience. I also know of a few on this forum and others that say theirs work fine.

Tim,
I very much like and copied your design. Having some surfaces on earlier aircraft scraped, or dinged by external control locks, I much prefer locking the controls at the rudders and stick.
Obviously, Cessna felt that way when they put control lock through the control column. In both Cessna's case and your internal lock, it is impossible to operate the controls without removing the lock.

I built this gust lock out of PVC for less than $20. I have been using this since 2012 and over 1000 hours and never had a failure in all kinds of wind etc. It holds the rudder, elevator and ailerons with just a slight amount of flex in the pvc. The hinge is designed so that it locks in over-center thus putting pressure on the rudder pedals. The rear end is held in place by a number 8 screw with a dome nut the fits into the end of the gust lock. It can't move out of place.
Sorry in advance for the size of these photos
