DIY throttle - Delta Throttle

Hey, don’t know if you guys have seen this but a dude on Reddit did a DIY throttle based on delta kinematics to allow strafe up/down/left/right and positive/negative acceleration. Pretty nifty. He’s thinking about doing a kickstarter to develop a kit using prefabbed parts but if you have access to a 3d printer and a bent towards soldering and model making you may be interested in his DIY instructions:

It’s an interesting concept, but I can see a few issues with this.

1.) How does it center itself when a user does not want to engage his strafing thrusters?

2.) The throttle mainly functions by the movement of his arm and takes the wrist mostly out of the equation, which the arm does not make fine adjustments and is not as accurate as the wrist. Fine motor skills use small muscle groups such as the hand, fingers, thumbs. His design focuses on gross motor skills, which use the larger muscles and focus on walking, maintaining balance, coordination, jumping, and reaching. (Hence the reason the Space Shuttle still uses joysticks and hats, because the wrists, thumbs and fingers are one of the best tools for very fine movement.)

3.) Because of reason two, it almost seems as if it is near impossible for the majority of users to center the joystick.

4.) Generally with how human adrenaline works, when you have someone enter a very intense situation the heart rate will skyrocket, and typically can cause one to shake, resulting in the loss of their fine motor skills. You want to keep as much of your fine motor skills as you can by controlling your ship with your fingers and your wrists, not your arm.

I’ve been thinking about trying this out. Has anyone else here built it before? Wondering if anyone has any personal experience with the Delta Throttle

A cool concept, but as Havok pointed out the hand/arm is overloaded by controlling so many axes on a fine-grain level. It simply won’t work without unwanted input interference unless you use larger deadzones, which makes the whole idea pointless.
