Thanks for the replies everyone. The Viper actually worked really well in the WGT, but others said it wasn't working so well in 12th and that it was hit and miss sometimes as well. Including resetting during a race. So ... that is out for me.
I did a bunch of research in the mean time and found excellent results on the ORCA
VX-1 so I decided to go that route.
Would really love to know what is up with my RS Gen 2 drawing almost 5000 mAh every race.
