I had something similar happen to me when I switched to 2.4GHZ. I didn't crash but discovered that my regulator was dropping out because it was getting hot. I was using a 5.1 v regulator and a 2s lipo. The regulator couldn't dissipate the heat from dropping the voltage down from 8v down to 5.1v. I replaced the 5.1 v regulator with a 6 v regulator and haven't had a problem since.
I'm not saying this is your problem, but it's something to check.

Joe, were you running electric power at that time? I typically use about 50 mAh per flight in my electric power stuff, which equates to an average of about 300mA which would mean less than 1 Watt dissipation in the regulator. I doubt that is a problem unless the system was drawing a lot more current for some reason. I use a choke in the receiver to ESC cable now but I'm pretty sure I flew a lot of no problem flights before I installed it. However, I didn't have the receiver battery cables near the receiver/ESC cable. I'm kind of leaning towards that as the problem.
