Just throwing up an idea from the F3F glider community. We have used LDS (Linear Drive System) for a long time now for both flaps and ailerons with good effect (big surfaces and big throw is not an issue; single-side-hinged flaps can deploy to 90deg) and the design can be leveraged IMO. There is no need to go this slim as the original design is meant for glider thin wings, and the rudder bulging pocket could be put to good use to disguise the linkage.

The issue with the LDS system is torque. I used a similar set up on my F15 rudders I built. It worked on the aircraft since it has tiny rudders with low stress on them. I tried to use it on the ailerons on my F15 and ended up not going that route due to torque. You would need a to have offset hinges on the rudder to increase the torque on the F22 using this system so that's a no go. Still a good idea though and thanks! We need out of the box thinking to solve this and keep it hidden.

Pics from FLjets!
super strong crosswind all week. She handled it well.
I had zero issues with the plane. Nothing broke and flew it allot. Kingtech 260 was flawless. ARsmooth flight helped out with the very strong crosswind.
video of crossword nd flight and landing.

The IDS or LDS system use in gliders does not reduce torque. The arm lenght at the surface and servo is nearly equal so there is not a reduction in drive torque.
It is best to use 100% of the servo travel to get the desired control surface movement. Then you get the full amount of torque. It is the ratio of the arm lengths that matter, not their overall length.
Having setup a few gliders with these, I'll say they can be a pain to install, so you are not missing much.

Am wondering where has the manufacturer landed with the solution for the vertical stabiliser flutter issue. Other than the straight-up CF overall usage to build the stabs, there hasn't been any further news about the part on linkages. Kris, which version of the stabiliser are you flying this FL season? My thoughts too about Looping31's case, whether an improvement was found somehow.

im flying with the original system with the tighter drive units. It’s working fine and I’m flying her fast and hard.

Just curious, is the tighter rudder drive unit the only update to the T-One F-22? Never flew this model, and just realized it's been nearly three years since I put this plane on the shelf. Planning to get it flown this year, but would greatly appreciate any info regarding any vertical fin improvements made available by T-One.

it was a problem on my first I plan on addressing it with the next one. Its an angle problem, the cylinder is in a position that even when full closed it pulls open will the cylinder remains full closed. Only way to fix it is to move the air cylinder attachment point in the weapons bay.
