2.4 was a common usable voltage it may not be a good deal after all.
I wasnt aware that 3.4v was a commonly used voltage. The ones that are having the problem are the same ones that were failsafing with 72mhz.
If you have a sytem that stays above FLAT then youre fine.
Its the same old thing..failure to read and failure to setup correctly.
The same guy who uses wire nuts for his servo connections also locked out a 2.4 system....guess what he declared the cause of the failure?
