RE: 2.4G systems
I tried to keep up my FM system for years. I was finally convinsed to drop the cash for a spektrum. I'll tell you, I'll never go back. The servos/receivers are so much less expensive that I revived a crashed Carl Goldburg Piper cub. The Phoenx R/C 4 simulator plugs right in to the TX and is incredible. I recently had a issue with my TX. The elev. channel was intermittent. I sent it in to Horrizon Hobbys, and they took care of the problem and sent it back , no charge . That's a whole lot better than the reponse I had from airtronics.
