Hi!
Sorry! But a bigger cone does not give more lever moment! More area tutching the spinner yes! but not more leverage.
I use a 4cell (14,8v) LiPo , 2000mAh, on my Sullivan starter! Awesame power!
ARRRGH!
The larger cone grips the spinner better on the OUTSIDE of the spinner.
That imparts FULL TORQUE onto the motor.
If the spinner is gripped by the tip using a small cone, the cone can and will slide and you will NOT transfer the motor torque to the motor.
Not only does the larger spinner grip over a larger area, but the point of the "grip" is further removed from the spinner center imparting a larger lever moment to the spinner, and hence less tendancy for the cone material to release...
I did not mean to imply that somehow the motor produces more torque than it does normally. However a larger cone transfers that torque effectively.
