No, no, no. I was replying to Mongo's post about single stick radios. That post had nothing to do with curtis, it only had to do with the timeline of R/C radios. I have trouble seeing curtis doing a chaos with 2 button radios!
I only meant that single stick TXs came first because of size and cost, then the 2 sticks came around, and then the single stick heli radios came around. (No, I'm not an expert in "vintage" RC equipment but I'm pretty sure about this)
