Thanks guys,

Hi flyinwalenda

Good read on the Lipo thread, so I can eliminate the mAh. How long do you guys run your boats for per run? Everywhere seems to be about 10 min per batt. Im trying to at least get about 30 - 40min through however many batteries

- Water cooling is free and working and I always run the boat past me to check the water outlets
- Prop - Im running the standard 2 Blade Nylon and the standard Flex Shaft. Have only re-greased everything
- Plug connectors are brand new Gold 4mm Bullets that I changed so I could easily mix match and test across my RC's
- No engine sound anymore. When ESC was working, normal beeps and start up tune were coming from motor. I did notice that loudness changed randomly. When I initially plugged the ESC in, it was loud beeps, but randomly would be real quiet then loud again?

Thanks Wholehog, Ill get some 5.5mm connectors and I do have a batt checker and all batts at full charge are about 4.2v per Cell. Cut offs all occur at the 3.3v - Maybe its the programming. Ive just been putting the options to (default) as per manuals

I have attached some pics if this helps?
