I've seen so many people have problems with Spektrum. I've seen controls reverse, brown outs and just plain ''oh crap I ain't got it.'' People can argue back and forth all day about what is best, but all I know is that my Futaba never let me down. Sure, nothing is perfect and anything man made can fail at any time, but for my money and the welfare of my planes and the life and limb of those in the vicinity I want to go with equipment that has a good track record. That being said Airtronics is also a fine radio. The one thing Spektrum does offer as a lot of nice BNF planes. But what good is it if the radio craps out?
I am convinced that 99% of these control loss problems are not radio related at all but, are stalls. This summer one of our ''experienced'' pilots took off with his big corsair controlled by JR 9503, yanked her off the ground, she pitched up, banked left , level for a touch and snapped in. He swears to this day that his ailerons some how reversed as he was putting in right stick but, she was banking left. At the crash site controls all checked out ok so, he's decided that the ''reversal'' was intermittent.
I suggested he was stalled; his response was ''no way, he's flown the airplane many times before''. It happen to be at our warbirds event and someone caught the whole thing on video; you could clearly see the ailerons moving in the opposite direction of the airplanes roll ( ie. in the direction of his stick input so, no problem), the elevator at full up thus, the aircraft clearly stalled and not responding to stick inputs. BTW, the pilot is still convinced it was a problem with his JR radio.
Same thing again with another guy and his Aurora A9, yelling the proverbial '' oh crap, I ain't got it'' implying a radio hit when, again his aircraft was clearly stalled.
I've been flying JR/Spektrum 2.4 since it was introduced without a single hiccup.
