Mike,
My modified prop pitch has been turning a TH6 / 40-2CD combination for
may years. It has turned this array in heavy winds with ice. Even
thou it is a modified unit, it has plenty of torque. I use a small
variac in the power supply/ indicator box so that I can adjust the DC
voltage to the motor to compensate for very cold temperatures, etc.
GL with your project!
