I have just learned of a fault that resulted in loss of signal using the module upgrade on my two 10SXII. After the total loss of my scale P47 i sent both radios and both module sets i had just purchased,one still unopened, to Horizon. They found the antenna wire broken IN THE TX ANTENNNA and that it is a quality/manufacturing fault. He had to take the antenna completely apart to get to it. I was having range issues and was told to rebind and it seemed to cure the problem but i lost the plane on the next round at a contest.
Horizon is pushing the Brown out issue on the recvr battery voltages with major coverage of the Nimh packs made with the "new" battery chemistry. I will start to use five cell packs on everything and they agreed that would be a very suitable precaution. IF you find problems with range checking and or numerous failsafe faults please change to another TX module/ant and range check again. The chances of this issue being encountered again might be slim but it could happen again with newly purchased module/rcvr upgrades.
