I have one of the first versions, good for scale, not for combat. There is a very small delay when keypad is pressed. Probably ok for lights or music or any other simple non time critical function.
Awesome thanks for the info thegeek. I had no idea about the delay, that's great to know about for planning if I end up taking the plunge. I was thinking it would good for scale work and/or SFX work. Just the thought of all that functionality makes the old robotics nerd in me all giddy.
Take a look at any of the opentx compatible transmitters that support Lua scriping. Lots of opportunity for neat there
Thanks for the lead. I took a look at it and they look really cool. I'll definitely be putting some more research into finding out more.
