Those crimp connectors are aviation type and are used on just about every full scale plane out thier. I also used an aviation crimper that locks until the crimp is done. The duralite regulators would both have to fail with the AR9100 and thats not likley. I have lost little foamy planes all the way up to jets with spektrum. The transmitter is back at horizon now agian for the second time. It has something called a backup error now and does not work at all. I used the flight log all the time also. I feel that most of my problems are from the transmitter it self. The first time it went back the transmitter had a bad RF board and was sending out a reduced singnal.

Bottom line is the RF link with spektrum has been horrible. Having to use 2 receiver batteries 4 satlitle receivers and a flight log then still having to keep your fingers crossed for a decent RF link is total BS. My problems might be an isolated issue I dont know. But the more I look the more I see people having problems with the spektrum stuff. I dont see the RF link in question on any other 2.4 system out thier accept for JR spektrum.
