Hi

What prop do you guys reccomend for a Hacker A20/22L Electric Motor ?


As per the website they reccomend a 10x4.7 SE APC prop. I would like to use a regular prop not a slow flyer prop and am not sure which one to use.




I am using this motor in a E Flite Ultimate FX foam biplane !

Any help would be apprecitated.



Thanks Scott

Why do you want to use a"regular" prop? You will lose a lot of performance. Slow flyer props are optimized for the type of motor. They usually have more blade area, but are very thin and cannot handle the higher rpms of faster turning motors,

Hi




Here is a example of 2 props that I am looking at !

The prop I have been using is a APC elctric prop but i do not believe it is a slow flyer. The only difference between it and the "regular" APC prop is the base or shaft is thinner and honed out to accept the adapter or spacer rings.


WHICH ONE DO YOU THINK WOULD BEST FIT THE HACKER MOTOR IAM USING.

Thanks Scott
