Hmm, maybe what happened to my 540T on Saturday when I lost control and pulverised the front end (again). Not fixable this time. Brownout makes sense - 60A Plush ESC in mine has only 3A BEC, and 4 digital metal gear servos moving large surfaces through large travel, probably draws reasonable current. Although mine was probably a radio glitch probably due to proximity to the power lines, 4th time I've had control loss while near those lines. Need to be more careful to keep distance from them.

This reminds me... on saturday we had a number of pilots reporting brown-outs at the end of the strip... no idea why. I had one myself with the quad, lost it for a second or two then got it back in time, at least to level it before the crash... no visible damage.

However I then noticed that my transmitter aerial was pointing flat parallel to the strip when I was seated in the pilots box, therefore at the end of strip where I had the brown out, the quad was at the extended axis of the aerial (dont know how else to describe), in other words, the lowest strength signal.

I pointed the aerial up to point at my head, then flew the same exact track 3 times, I was FPV so I knew exactly the landmarks of the track I had flown when I had the brown out... but for the 3 times I never lost signal.

Im not saying this was everyones same issue, there is a known interference issue at that end, but it's a reminder to minimise risk of brown out by making sure the aerial is pointing up(or down), so youre not creating your own 'brown spot' in the circuit you are flying... or anywhere else
