Rules of VTA: Motors and Batteries

Published by insulinboy at 9:57 pm under R/C Edit This

The rules of VTA racing are fairly simple. You’re restricted to older style motors and batteries or a newer sub standard motor and a newer style battery with gearing restrictions.

 

Your allowed to run a 4 cell pack of NiMh (nickel metal hydride) batteries with a 4600 mah limit, with either a 27 turn stock type brushed motor, or you may run a 17.5 stock type brushless motor. If you so chose to run a 7.4v lipo (lithium polymer) battery that you must run a sub stock 21.5 brushless motor. Currently the only Roar legal 21.5 motor is the Novak SS21.5 pro brushless.

 

When running a brushless lipo setup with the 21.5 motor you are restricted to final gear ratios no lower than a 4.2 final drive ratio.

    good to know, I’m always confused what VTA rules are. This is a great series you’ve started and I can’t wait to learn more.
