BENCH TESTING OF THE POWER UP ZOOM 450 MOTOR FROM HEADS UP RC

Just finished up some more testing on another motor, the Power Up Zoom 450 from Heads Up RChttp://www.headsuphobby.com/Power-Up-450-Zoom-Outrunner-Brushless-Motor-H-225.htm

I tested on the 6x4 APC, 6x3 and 6x4 EMP props at low, medium and high timing settings on my ESC. I used a Turnigy Plush 40A ESC, but based on the numbers I got from the wattmeter I could easily use a 30A ESC to save a little weight. Again I tested at 50% and 100% throttle to determine best cruising efficiency and high end power and efficiency.

Here are the numbers for the 6x4 APC prop at 50% throttle -

• ESC at low setting - 14A/166.8W 520 gr/18.3 oz of thrust;
• ESC at medium setting - 13.2A/158W/515 gr/18.2 oz of thrust; and
• ESC at high setting - 14.6A/172.1W/560 gr/19.8 oz of thrust.

6x4 APC at 100% throttle -

• ESC at low setting - 25A/285.6W/820 gr/28.9 oz of thrust;
• ESC at medium setting - 25.9A/291.5W/840 gr/29.6 oz of thrust; and
• ESC at high setting - 26A/293.3W/830 gr/29.3 oz of thrust.

6x3 EMP at 50% throttle -

• ESC at low setting - 13A/150W/590 gr/20.8 oz of thrust;
• ESC at medium setting - 12.6A/147.5W/580 gr/20.5 oz of thrust; and
• ESC at high setting - 13.8A/158.6W/580 gr/20.5 oz of thrust.

6x3 EMP at 100% throttle -

• ESC at low setting - 22.3A/250W/848 gr/29.9 oz of thrust;
• ESC at medium setting - 22.9A/253.8W/898 gr/31.7 oz of thrust; and
• ESC at high setting - 24.9A/287.6W/860 gr/30.3 oz of thrust.

6x4 EMP at 50% throttle -

• ESC at low setting - 14.5A/174.1W/522 gr/18.4 oz of thrust;
• ESC at medium setting - 15A/177W/540 gr/19.1 oz of thrust; and
• ESC at high setting - 14.8A/181.5W/534 gr/18.8 oz of thrust.

6x4 EMP at 100% throttle -

• ESC at low setting - 27A/309W/760 gr/26.8 oz of thrust;
• ESC at medium setting - 28.4A/324.5W/792 gr/27.9 oz of thrust; and
• ESC at high setting - 28.6A/319W/814 gr/28.7 oz.

I did a bit more distilling down of the numbers from my test today on the Zoom 450 motor and based on the numbers I got, this is the setup I would use. Please don't take it as the only setup to use on this motor, depending on your motor, ESC, etc, you might get better numbers than me, this is just what I got today and how I would run this motor in my planes.

I did some calculations based on thrust produced versus weight of the motor and thrust versus amps drawn to determine if the weight and efficiency of the motor produce good results for the overall performance of my plane. The Zoom 450 that I used with prop, X mount and bullet connectors weighs 87 gr/3.07 oz.

The setup I would use -

• prop - well balanced 6x3 EMP;
• ESC timing set at medium;
• at 50% throttle this gives me 12.6A/147.5W/580 gr/20.5 oz of thrust;
• at 100% throttle this gives me 22.9A/253.8W/898 gr/31.7 oz of thrust;
• at 50% throttle I am getting 6.1:1 thrust to motor weight ratio, but an excellent 1.6 oz of thrust per amp drawn, this is one of the best mid range efficiency results I have seen in all the motors I have tested; and
• at 100% throttle I am getting a 10.3:1 thrust to motor weight ratio and 1.3 oz of thrust per amps drawn, again a very efficient ratio and this is also the highest amount of thrust I saw in testing today.

I have tested and flown this motor in a few planes, it is a very solid and strong motor, I think the numbers with the right prop and ESC settings give great mid range performance and pretty decent high end performance compared to some other motors. After the 6x3 EMP prop, it is probably most efficient based on my data on the 6x4 APC and not very efficient at all on the 6x4 EMP, but again your results may differ.

Cheers,

Scott
