rg197r27:
I am finally getting around to finishing my 1:12 Tamar I was wondering where members have installed there lead acid batteries either forward of the motors or along side the motors please advise


Thanks in advance

Hi Rich,
I put mine on trays, either side and just aft of the motors. They can slide fore and aft on the trays to help trim the boat. Then held down by velcro straps.

RICH......you need your batteries as low as possible to stop rolling of the boat especially at high speed turns.


if you are running on brushless motors I wouldn't use sealed lead acid either, but lipo's.......and these could be Velcro taped into the bottom of the hull forward of the motors and speed controllers.

Flundle (Speedline Models):
Rich, if I were you I would put the batteries (two 4cell lipos) up front and as low as possible. The Out-runners for this model (BL4030) will cause lead acids (and maybe Nicads too) to stall internally resulting in the motors pulsing every second.
The Tamar naturally leans into turn so the C of G needs to be as low as possible.
Put the lipos along the keel, well forward of the motors.

kinmel:
The model is powered by brushed motors. Each has 2 wires from it's Esc.

Batteries still need to be forward and as low as possible.
