So I finally finished my gp310 after working on it on and off for about a year but now im looking for some insite on setup/parts. I finished the boat up in a rush to bring it out to our final outboard race of the year to test it out but ran into a few problems with the main being I puffed a brand new set of batteries first run but also was running into a issue with the boat not wanting to stay in a straight line, any help is much appreciated. Boat setup- Tenshock P-Limited motor flycolor 150a esc 2 5400mah 150c 2s lipos ran in series just cause that's what I had that would fit. 35kg servo from Amazon. I'll have to check the prop I ran but I can say the motor and esc were ice cold after running and the batteries were cooked. I will grab some pictures in the morning and add them on here of the boat and setup.
