440 prop on a jae21

[Mike lasorsa]

Had anyone tried this ? Just curious to how a small prop performs on these boats

I have tried, but it is not enough load for most 21 motors. You will want something closer to 47-50mm if using a 1.4 pitch ratio.

I use something close to that now. I have a small pond close to my house so I wanted to try the 440 prop to slow it down some since the bigger prop is more like a wide open only kind of deal

Mike,

Try a 1445, H-4, or H-5 they will go up and down
Easily on a small pond.
