Yes, that's a T16000M and a CH Pro Throttle taped together with duct tape.

Process destroys T16000M; does not destroy pro throttle.

Currently 4DOF. With some work, planning to add rotation that will make it 5DOF.

Needed a screwdriver, dremel, duct tape and eventually epoxy/superglue.

Works great - even with just the duct tape, they are solidly linked together with no slippage. After dremeling the shafts slid into one another easily. Connects to computer with two USB ports. I may decide to make it shorter in the future.

I can post instructions and some photos if needed.

Currently I have roll/throttle on the big stick (once forward strafe isn't bugged, I'll have strafe on that y axis instead of throttle), and then lateral and vertical strafe on the mini-stick.

Lateral and vertical strafe are currently bugged and you can get "stuck" in strafe - to stop this you have to wiggle the mini-stick. No amount of deadzone, sensitivity, axes, or any kind of adjustment has been able to fix this for me. If you know of a way, let me know!
