Building a Slow Stick from scratch

The GWS motor will take 100 watts with or with out the gear drive. The prop size with out is 5x4~6x3 the prop size with a 3 to 1 gear drive is 10x6 DD. if you were to use a 5 to 1 drive it would be a lot bigger. The bigger the prop the more thrust is made for the same watts in general

Flying Weight
405~440 g (14.3~15.5 oz)
Rule of tomb is 100 watts per LB 40 watts would give an all up weight
Of only 6.4 OZ
They do have a double motor gear drive?
It is for the 100/350 size motors
As snappy has said the cost of a motor at HK is so low it would not make sense to get a gear dive at ~$10 each
The ESC (brushed) is cheaper and I use it all the time on a lot of my GWS kits. It is just as easy to use and the other components do not cost as much. You can make 2X6 cell NIMH (7.2 volt) battery for ~$12 and when the kit comes with a 400 EPS it’s the fastest and easiest to do

Thanks for the specs. I think I will try the EP6030 or the EP7035 without gear reduction.

Also, I may have read the specs incorrectly for the XFLy. At maximum power, the specs also states that it can pull 12.5 Amps at 6 Volts. This equals to 75 Watts.

I am beginning to understand that the power output of a motor is greatly influenced by the type of propellor that I use.

What should I be careful of when running the motor so that it does not burn out? Volts or amps? If the motor is rated at 7.2 Volts and I keep within this voltage then I should be fine. Right?
