Craig DX6's are great for robots, but unfortunately there now old hat and all DSM1 rx's are getting hard to come by...

Jeroen - I'd suggest a dx7, I use one for my rc plane/robots etc and it's great... Plus it works with DSM2 rx's and it failsafes on all channels, also are a good price on eBay now. Dx6i I'm told only failsafes on the throttle?
