Interesting thread. I've had an RDS8000 since they first came out. So far, no problems like the one being discussed here. I do need to send mine in anyway, as the gymbal on the right stick is cracked where the stick mounts. I probably shouldn't trust the expoxy and microballon fix that got me thru this past summer. I really like mine, and can't see the added cost of the SD-10 given I fly mostly WW1 stuff.
