Speed Passion Reventon Pro 1.1EX help

[Tobyw]

Hi,

Hoping someone can help me here.

I have the above ESC and have loaded the STCK0 firmware (blinky mode) onto it and yet it wont power up on a 1s lipo. All the websites and even SP themselves say that the speedo is compatible with 1s lipo.

Any ideas? It powers up on any other profile with a 2s lipo just fine. Before you al say..Yes, I have tried several sets of 1s in case it was flat...

Please help

Cheers
Toby
