John, thanks,
Yes it is indeed but snapped as I motorcycled past last year. I wish I was in Argyll but I'm up in Aberdeenshire near Longside. I'll make contact with the local Buchan Aeromodellers soon and get back into things.
All makes sense yes. I'm a bit wary of Spektrum and think their RX's quite expensive although the DX6i I own has DSMX on the cover of the manual.
Another solution I have is to continue to use the cheap but excellent Ikonnic KA-6 I have that was supplied with an ARES model I bought a couple of years ago. I notice Wheelspin models are selling off the last of their Hitec red 6 ch Rx's for under a tenner so will have some of them. That will get me flying cheaply right now and when funds allow I'll buy a Hitter TX.
Many thanks for your reply.
