Bob, I recently lost a 38% Extra for unknown radio loss. After reading some of the posts here I think I have a scenario. I was running 2 4000 mah li-polys and regulators plugged directly into the RX. I have read in several posts that the regs don't like to be set up this way and one will always dominate. What I think happend and what I am seeking your opinion on is that it appears to me that one reg was dominate supplying power to the RX and servos. I was one flight away from having to re charge. The failure occured right after a 1 1/4 snap on a downline. What I think happened is that the doniate reg heated up and shut off. The only hole in this theory is that the other reg should have kicked in and kept the power flowing to the RX. Obviously by getting one of your Batshares it would solve this problem. I am strongly considering one of the power expanders as well. I just don't want to repeat the loss of another airplane.
