Stick grip hits panel

Bart

Well Known Member
I've installed an Infinity Stick and find that the grip hits the panel in the full foward position. Have other folks had this happen? If so how did you remedy it? Do you need to if you are getting the Min/MAx travel on the flight controls?
 
2 things that helped me

1. Initially I had the problem with the grip (CH/TOSTEN) hitting the panel even after they were cut down to min. I cut the verticalupright piece off fromn the curved portion, rotated the vertical aft 22 degrees to provide clearance, then had them Tig welded.

2. Once I had all of the instruments and EFIS. installed in the panel with the panel in the plane I found that I had some interferrance wit hthe grips hitting one of the knobs on the EFIS. I remeasured the up/down travel and compared it to Van's spec and found that I had more than the plans called for in the down direction so I made a simple elevator stop out of some alum angle ind installed it.

I also had this concern, best advice was to wait until the tail was mounted, and the elevator travel checked.

There seems to be a lot of excess travel without the entire assembly.

In addition, at least for the CH units, you can rotate them a bit, gives not only better clearance, but is actually more comfortable fit in your hand.

YMMV with the Infinity grips.
 
Some grips are a bit tall....... so shorten the stick a bit!

When I changed to a different Ray Allen grip, I had to chop an additional few inches off. At least if you chop too much, a different grip can probably make up for it.

The bottom line, is that if you thumb rests on top of the stick for any controls, then the thumb should also miss everything on the panel. And this is assuming that flight surfaces are mounted and at their stops.

Wait until you have the elevator installed. The stops in my 7 kept the stick from going all the way and hitting the panel.

Also, if you are in flight and push it that far forward, you better make sure you are securely belted in because you are going neg G's very quickly and looking directly at the ground.
 
No doubt I'm going to have this issue

and will have to cut/chop/extend something on each stick when the time comes. Right now the issue is trial-fitting the Infinity grips on the sticks - will need some sort of insert between stick tubing and the insert JD provides with the grips. 7/8" thick-wall aluminum tubing should work, with a little lathe work possibly needed. Do I want 2024T3 or 6061 for this?
 
Good save!

Once again this place proves its worth :D

My two grips came with the 3/4" ID inserts. I need the 7/8" ID. Why the previous builder ordered them that way is a mystery, but who knows, maybe they were an ebay find.
 
I had the same problem. I cut the vertical as short as possible and cut 7/8 in off the bottom. I still couldn't clear the panel with the original Torsten grips which have quite a bit of forward angle. I swapped for the Tosten military style grip and adjusted the length of the elevator linkage at the swinging bell crank. Now I have clearance and full range elevator per specs.
