You can use 8x4 or anything near it. Prop sizes aren't exact so you can get anything close like 9x4 or 7x5. Just get different size propellers and experiment to see what you like. But here is a good one that works nice. OR001-00308A
Kevin, I use the FC 28-22 1200kv motors on lots of projects. This motor has similar specs, so I would recommend using an 18A ESC and either 8x3.8 Slow fly props, or 8x4 3blade props. This is a great combo and seems to have excellent power and the longest battery life. So, the best compromise of power and energy consumption. I'm ordering some of these motors too because the FC 28-22 motors are sold out. I intend to use them in the same manner. This Tricopter has the FC motors on it, but I'm building a Quadcopter and will put these motors on it. Hope this helps and Happy flying!
I have the (old timer) cub and I want to up grade to a bell (outrunner) motor instead of the stock 380, also want to upgrade with new esc,plus I want to use a 1000 3s lipo battery I am using a 7 inch prop,need help, any suggestion least amount of money..
assuming that the current motor is a brushed and gear reduction setup. I would remove the motor and gear drive, weigh it and get a brushless motor of the same weight. takes care of cg problems as gear setups/brushed motor are heavier than brushless setups. with a brushless mtr an ESC for a brushless mtr is needed.I don't know what an "Old Timer" cub is so' I can't be any more specific.
old timer is a J3-cub,hobby king number sku-j3arf, the 380 motor is brushed and has no gear reduction straight motor direct drive prop goes right on motor shaft.this plane is very similar to the piper cub harbor freight sells pretty basic, has a cheap esc and is powered by a 600mah 8.4v ni-mh battery. if you look at hobby kings planes you will see the old timer cub,
if you go back to the j3 page, it will give the specs for the stuff needed to get this plane in the air. the only thing is the motor listed turnigy 2408 must not be made as I can't find it. there are alternatives listed. the motor on this page might be a good one. check out the discussions below the plane.
Thanks I guess you Can't get something good for that price,, I'll keep shopping around.
i bought this to use in a non moving project. its 12 pole and the coils are not would ABCABCABC. magnets are strong, and coils are sloppy wound, but no rubbing and the construction seems good.

Just flew with this motor.....maiden flight was great with this motor in strong winds......second flight....welll.......the motor clunked out just after take off...You get what you pay for!!! would cost me more to ship back then what the motor cost.
