Cheap remote control keyboards from china for flight!

Why is this better than using a trackball?

Why in your opinion televisions and remote appliances come with remote
controllers and not with a trackball?
Usability, they call it.
Apart from this, point me to a bluetooth HID trackball costing less than 10
dollars, with a LiPo battery, no wires please.
You can argue that your trackball is great. Nevertheless people with a
television at home do not use trackballs.
Watch the video and figure out yourself how many dozens time this keyboard
is, compared to the trackball.

Your reaction seems defensive, but I did not attack. From a "maker" point of view, I think that it is cool that you mapped the array of keys onto the screen. But it is not obvious what that buys you compared to a mini-trackball.

I only have space for one cursor controller in the sailplane, so I'd favor the one that works best. Bluetooth and batteries make installation easier, but I don't want a loose remote control floating around in negative-G. You could velcro your keyboard to your thigh.

I agree that using a trackball takes a bit of practice, but it is very usable after you get used to it.

I thought this was covered not that long ago in another thread - too lazy to look it up. In a nutshell, try using a trackball when scooting along on a ridge at 100kts with +/- 2G bumps every couple of seconds. Not fun. Key-based (up/down/left/right/select)controllers with positive tactile response and discreet actions are SO much easier to work with. HOTAS controls on military aircraft are a good example.

Before she retired, my wife had to use a trackball due to carpal tunnel
syndrome. At least with those that we bought for home use, the ball was not
sequred in the device and, under negative G, the ball would fly out.
