  • Don’t always consider cost an important factor.
Purchased for a new build of a fixed gear, fixed wing aircraft and found that channel 4 was faulty.

Have never lost a plane with any dual ant spectrum RX (636b, AR6210, 637T)...but I put this in and it went to fail safe for no reason and destroyed the plane 1 minute after take off. If you are in a city vs the country or in a high interference area vs low I would not risk you plane. Just like the 630, this is a park flyer RX ... show more
