Hobbywing/Speedpassion delay on startline?

[mdb_75]

I've got three different Hobbywing Xerun esc's, one 120a, one 60a and an Xtreme stock one. I've used the first two for over a year and they're generally great. Occasionally though at the start of a race they will have a slight delay, not much, maybe a second or two before the cars move. Even if I've driven to the start line.

The new Xtreme stock one seemed fine last week, but tonight at the start of my final it cost me pole down to fifth place because of the delay!

Now all esc's have had more than one version of firmware on them which hasn't fixed them. Currently the newest mod firmware's (as of a couple of weeks ago anyway) on all three esc's.

My radio gear's recently changed from a Futaba 3GR to a 3VCS (just to go 2.4) and that's made no difference.

I generally use Speedpassion V3 motors (7.5 and 8.5), but am currently using a Losi Xcelorin 8.5

Sensor wires have been changed too.

Any ideas, and does it happen to anybody elses??!
