Xcelerion speedo issues. Help......

[jimmiprice]

Guys ive got a problem with my Xcelerion brushless combo which i need a spot of help with. I think its a physical problem rather than a programming issue but any help will be appreciated.
The problem i have is that sometimes the speedo doesnt brake, sometimes on slow sections sometimes at the end of the straight or other places where it can go all wrong quickly. I can do one lap where the car will brake on demand no problems then the next lap for one random corner ill lose all brakes, although i have the stick back to the stop the car just freewheels. The speedo motor combo is brand new, ive tried it with both lipo and nimh with no difference. Ive also tried adjusting the drag brakes and had no luck. Its not that intermittent either in a 5 minute heat it will have probably ten non braking moments. My thoughts are that its not programming as it would have no brakes permenantly if that was the case.
I need to know if its something i can programme out or if i need to return it. If it helps i can download the values from the speedo and post it up.
