Really, with the other items, the Tx itself is almost free.

I've heard good things about the SD-10G but so far I just haven't felt that I need anything fancier than the RDS8000. I'm really only interested in WWI scale so my radio needs are modest. I did read, however, that it's better to use digital servos with the Rx that comes bundled with the SD-10G (see the second to the last paragraph of this review). I I don't use digital servos at all. I also don't use Airtronics servos anymore. They just aren't available. So I use either Futaba (with the tab cut off) or HiTec.

PS. My problem is that I use the US-style Mode 2 radios but in Japan you can only get Mode 1. So I either have to order from the US (shipping is expensive) or buy one there and bring it back myself during a visit.

Regarding the twitching my plan is to first try a battery that I am 100% certain of. Then disconnect one servo at a time to see if any one servo is the cause of the problem. If I still don't find the problem, I might remove all the servos, connect them directly to the Rx to see if it might be the leads causing the problem. The only source of interference that I can think of would be the braided steel cable (1.0mm) that I used for the tail rigging wires.

For the hinges, I'm just going to have to cut off the aileron and start over. It feels plenty sturdy with just the 4 hinges, but that's just sloppy, lazy workmanship.
Yes the RDS8000 is a great radio.......Nice thing with the SD-10G is that you don't have to worry about which mode it is as it is very selectable with 4 modes , plus almost unlimited programing combinations that is only limited by ones imagination. Strange that you can't get Airtronics servos as they are readily available thru Ebay.com and other sources out of China. Same with receivers...... just have to shop. About using digital servos with Airtronics receivers , that is only a requirement for the FHSS-3 protocol but if using the FHSS-1 that the RDS8000 transmitter uses then your good with either analogue or digital. The SD-10G allows you to select either FHSS-1 or FHSS-3. If you have any questions , you are welcome to PM me any time.
Thanks

Your plan on how isolate your twitching servo ; is a good one. With the Airtronics system , I don't think the braided steel rigging wires , should affect it as I use pull-pull wires (short or long) for the rudder; all the time with no issues; even long servo lead runs but I do use twisted servo lead wire and make up my own extension leads.
