I have been having  a great time with this sub ,to me its a hole new sub ever since I made the above mods,the cooling actualy works very well,when I run the motor out of the water for a while the cooling fins get warm ,in the wter they efectively transfer the heat out of the sub.

The running time has gone from 15 minutes to almost 45 ! Wow what a difference Lipos make and take about the same to charge,I do not need to remove the bats from the sub ,there is a charging lug installed.

This sub is so easy to use a cave man could have loads of fun,at full I have no idea how far up into the air she will jump as this thing put out pounds of thrust at full and its waight to trhrust ratio is way up there,so I need a good deep run to start of at and give her all shes got to make the highest jump ossible ,I will make a vid of her at the up coming Blue Spring run where the water meets this criteria for this subs aqubatics ,there is no way it can be done in my small pool,cant wait for that day on the 12 th of October,I wiull also bring the SB-2 and Octura ZX,it should be a blast with lots of under water Video!

She has been newly repainted to a bright red with auto mototive enamel and several  clear coats,came out nice and slick.
