Problems with the Synthesized JR
I installed a JR synthesized RX in my Cap and started flying it last week. The 7 channel Spcm Rx is a very nice unit with a 20 plane memory and full mixing. However from the first flight I have had some anomolies. It would once or twice during a flight just go nuts, in the elevater/aileron channels. I checked all connections and even swapped out the battery with no change. I tried different channels as well. It is not a repeatable fault. I can not re-produce it on the bench and have no idea what to do. It resulted in a catastrophic crash on landing when the plane snapped inverted and nosed in from about 40 feet above the runway. I am now out a beautiful flying plane that only had 15 flights in it.
Can anyone offer advice.
I did try to use the search funtion as i am new here and did not want my first post to be some "Help me I am entitled" type of hello

Had you flown this plane with a different receiver?
What transmitter are you using? You mention 20 model memories but receivers don't have model memories so I presume you are talking about the transmitter. With 20 memories, is it the JR 7202?
Did this problem only occur once?
What else can you tell us.

I bought a JR 6102 and it came with a 700 FM reciever. I bought an additional reciever, the 790 which is SPCM modulation. I put it in a second plane and programmed (scanned in) my radio to use it. It took about 5 minutes for the controls to go completly wacko and then finally it didn't work at all. It was alternating between fail safe mode and regular. In other words, the signal was intermittent from the Rx. It would go into fail safe and then out and back and forth until finally it worked no more. I sent it back to JR and they said the RF output board had failed and they replaced it. This could possibly be what is happening to you? Who knows but that was my experience.
I asked the tech if this was an ongoing problem and he told me it wasn't but I was a little unhappy because I had only owed it 2 days when I had to send it off for repairs.
