Ialso recently switched to the RDS 8000. Ireally like it. It fits well in my hands. I looked at the new SD-10G yesterday, and it felt strange to me, a lot bigger.
With the new receivers from Airtronics, the RD will suit my needs for a long time. Ican't wait to get the new Park Flyer Rx, I've been wanting to try some of the Plug and Play airplanes, although the LiPo's scare me.
Hobby People has the RDS 8000 with an 8 channel Receiver for $159.00. It's a great radio!
