UL-1 2030 KV HOW many watt's output ?

[Andris Golts]

Hi all looked at the specs for this motor stated 6 poles butt no watt rating .Would any one know the watt rating for the 2030kv ? I trying to compare this with my 4-pole 3674 1900 kv 3.5D Leopard rated at a 1000 watts to decide which motor to experiment with in my JAE.21 rigger.Regards Andris Golts.

From logged data in a P-Ltd rigger for a 1:20 second race I show 975W average with a peak of 1400W.

A motor's rating and what it can actually handle are usually two different things. It is common in FE boats to exceed the "rated" watt output with many motors and still have them last - the AQ2030 is an example as it is rated at 50 amps continuous but most of us exceed that by 50-80%. There is no universal "rating" method either, each manufacturer decides this for himself making comparing different motors difficult. One manufacturer may rate his motor at 1500W while another with an almost identical motor may rate it at 1775 watts. One is rated at 14.8 volts and 100 amps and the other at 22.2 volts and 80 amps. And these are not usually output watts, but input watts - again no universal rating standard. The AQ2030 has a maximum voltage of 18.5 and 50 amps continuous for 925 watts, but on 14.8 volts it would be just 740 watts.

In the OP's case, he is comparing two motors of different sizes, compounding any comparison issues even further...

I thankyou both for the excellent information. Regards Andris Golts.

The AQ motors will pull 50a continuous, 100amps for 3 seconds before starting to over heat

The other users here have provided some very useful and valuable information. Another thing to consider is that you are dealing with different pole counts. If everything was equal, a motor with more poles will usually have more torque due to the fact that for the amount of input (work) it takes to turn the shaft 1/6th of a rotation. Now there is a factor of overheating on a smaller motor and the efficiency of the ESC with regards to how well it handles the additional pulses in order to achieve a single rotation. At the same time, a larger motor will have more torque courtesy of the increased size and magnetic fields. Also, you have to take into account the differences in weight and the changes that it may impose to your CG and ride attitude. This means that if you didnt change anything and swapped the motor, one may seem more powerful than another, but if you moved the CG to the same place on both setups, you may get a different result.

This is why most of the seasoned users will rarely ever say that one motor is faster than another for a particular model unless there is a consistancy of where the motor could be placed for CG or limits because of how much you can move the battery.

Meanwhile, we haven't even begun to address how well a prop runs on a particular setup which can be another factor all together.

Regardless, if you decide to try different motors on the same model, consider starting from scratch with respect to ride setup, prop choices (start small) and work your way up. You may discover that you like running one setup over another, especially as it relates to the props you have available.

I hope this is helpful. Happy testing!

Both motors will work well in the JAE, the UL1 motor is the most popular motor for it by far, the 3674 is not really comparable it is a much bigger motor with a lot more mass allowing more power or the same power for a longer time before overheating. I have run a Leopard 3674, at similar power levels to Tyler's UL1 powered JAE, but for 5 minutes 10-20 seconds while still maintaining reasonable temperatures.

The UL1 motor is a direct drop in fit using the stock Zippkits hardware, whereas the 3674 isn't quite, set in the Zippkits motor mounts using the predrilled holes in the tub sides the tail end of the motor will stick up past the top of the tub a few mm, and it needs either; a small power bulge in the stock ply hatch, a vac-u-boats/Zippkis ABS canopy, or elongating the holes in the tub slightly and laying the motor down a couple of degrees more (possibly needing a very slight S bend in the stuffing tube).
