Thread: Does Horsepower Count in a Gear Motor for a FCG

Tweet

Ok, because I know NOTHING about motors I need to ask this question. My hubby is going to build me a FCG this Halloween and went out and ordered a gear motor. The original motor from Dayton (the 2Z806) as you are all aware is no longer available so he had to go with another Dayton motor.

The motor he has bought is the 3M096 and it is slightly different than the 2Z806.

The 2Z806 (discontinued motor)
RPM 6
Horsepower .03
Torque 25

The motor we bought
RPM 6.9
Horsepower .01
Torque between 27 and 35

My concern lies with the difference in the horsepower of the motor. The RPM is higher, the torque is higher but the horsepower is lower. Will this effect the movement of the prop in a negative way? Am I worrying for nothing??

No, torque is more important. Horse power is more a measure of efficiency. I would be more concerned about the RPM at 6 a FCG is on the fast size 5 or less looks better in MO

Most of the time if a motor is just a little too fast you can add some weight to the prop and it will slow it down. It's never good to bog a motor down but I don't think going fro 6.9 to 5 rpm will hurt it much.

Something a lot of people forget is that there are other ways to change the speed besides lowering the voltage to the motor. Put a small gear or pulley on the motor and then a slightly bigger one on the shaft that is actually going to run the prop. Connect them with a chain or belt. The final speed will be slower than the motor speed.
