I installed my new gust lock from Antisplataero in my -9A today for the first time. I had watched the video twice to insure I was doing it right because I couldn't see how this thing would work with a simple angle on the stick and the fork on the rudder pedals. But with a 60 day money back guarantee, I figured, what the heck, the other items associated with the nose gear worked well so this probably will too. After installing I still quite understand exactly how it works but it does. With a few adjustments to the length of the rods by changing the matching hole alignments and getting the small pin inserted, it fit as advertised. I really suggest you make only a small mark on the inner tube for first fitting reference, because it took 3 different adjustments to get it just right. Additionally, you must lock the device to the stick first, just under the stick grip due to the angle it is welded to the tube. If you do as I did the first attempt you will find you can't get the pin through the two holes behind the stick. Next I extended the tube until the reference mark showed on the inner tube and inserted the smaller pin. Then bend the device upward at fork attachment and place the forks in position so that as you straighten the bend the forks engage the rudder pedals. The last action is to simply straighten the device and slide the locking ring into place. You do this by lowering the lever and pushing with you foot until it is straight enough to allow the locking ring to slide into place with little effort. It took me about 5 minutes to figure all this out and after a couple practice fittings, I could get it in place in less than 30 seconds from start to finish. It really looks professionally made, very "airplane" looking piece of equipment. It folds up very nicely to probably less than a foot long and 4 or 5 inches wide and is very lightweight. I called Allan with what I thought was a problem and he said if I wanted, I could make a slight bend and not to worry, if I messed it up he would replace it at no charge. I decided not to bother, but I think that's pretty good confidence in your product to make that offer. I expect the gust lock to last as long as the aircraft, it is made that well. I recommend this product to anyone who wants a quality 1-piece control lock that fits inside the cockpit that is a snap to install and remove and stows away behind the seat back. It is light enough to Velcro to the back of the seat back if needed. Dan
