All i can say is ive got a couple of the Losi speedos, both earlier models and they work very, very well and have done for oohhh 8 or 9 months now - i just dont update the software.
If it works and does what you want it to do, leave it alone....
Not much help for you lot i admit, but honestly when they work they are a damn fine speedo for the price. Here's hoping they will sort you all out with replacements
