Well done Scoota. That is a very good speed.Several boats in various stages of destruction -
Bat temp. and good lipos. I ran low 50's a few times and thought something was wrong you could tell it was off just by sound. I did that a couple times at the end of the day, and it left me wondering. Then i had time to run again after a low 50ish run i charged the batteries up and warmed them up some more and ran a high 57.Comment

Adding 12-18 ounces of lead at the CG will keep the model on the water and make it less prone to take off. Sometimes you go faster by adding weight.

Sv 27
Scoota,
I see your in Australia, me also, I have just ordered a SV 27, and a couple of 2 S lipo's for it, do you charge your packs as one, ie, balance all 4 cells?
I am looking at chargers and are just a bit unsure of how to wire the balance lead.Comment
