Help me decide with this poll

Darin, in your opinion, which is a better motor regardless of kv, the BJ or UL1?

Well... the BJ26 motor is quite a bit better quality than the SV27. It has more KV and about the same torque.

I haven't had a UL1 apart. It appears to be a nice motor. I have a brand new one here to try for one of my applications...

The "Better" motor is the one that makes your particular setup work... In a P-Spec Hydro, I'd opt for the higher KV, less torque setup, because most riggers handle better with a smaller prop spinning fast, as opposed to a large prop.

For Offshore, I think the BJ26 is the motor to have...

If you can swing a decent prop, you can go JUST as fast with the BJ26 motor as other setups will go with the UL1.

The key, in my opinion, is to match up the package... It's not just a matter of dropping in a different motor...

i would like to see the b/j and sv27 motors tested in somthing other than a bench test were the motors are not being pushed very hard
then see what sort of numbers come up
looking at darins chart the sv and bj motor are putting out around the same watts but the sv27 motor is hardly dropping any kv under load plus the chart shows the bj motor producing more thrust yet the watts or power out put of the sv27 motor is slightly higher

Have at it, Man... Winding one of these up under max load on a bench isn't the safest thing in the world to do, especially when an airplane prop isn't exactly designed to spin at 25,000+ RPM... And I'm more interested in racing and building boats, than building water breaks or whatever would be needed to truely dyno one of these things.

I wasn't trying to get exact, ultra specific numbers... just some basic estimates on this stuff... And the numbers bear out on the water, so I'm good... Not interested in blowing these things up in my basement.
