got given a couple of low rev motors...

They are Hype -Alpha AL28-760M, small motors but very nice, seem to good to waste !! and I got a couple of 25A ESC too. I am wondering what kind/size/pitch of prop I could use for these to get some performance...maybe a 3 bladed one?

Any suggestions would be welcome

Thanks in advance

Well a google suggests they are 760KV motors, suitable for about 10-15A or so.

So I'd say 10x7 or 11x7 or 12x6 on 3s.. and go from there.

These are not high power motors, but wonderful slow RPM motors for big props on light models, judging by the specs anyway.

Any data you can find from an Axi 2212/34 (740Kv) should be in the ballpark for your motor.

There is a YouTube video of a MiniMag using that motor - with 9x6 APC E on 3s.
