BENCH TESTING OF THE TURNIGY D2826/6 2200 KV MOTOR

Hi everyone -

Just finished up another round of bench testing on another popular motor that is on the RC Powers Master Parts list, the Turnigy D2826/6 2200 Kv motorhttp://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=12919&aff=46898

I have used this motor on several different light weight parkjets and it works very well. I tested it on three different props when testing my lightweight F18, but never played around much with the settings on my ESC to see what sort of thrust and efficiency numbers were being produced. Once again I found that this is another motor that seems to like the 6x3 EMP prop from a standpoint of thrust and efficiency. I have only ever used a 6x4 APC prop on this plane, but will now be switching to a 6x3 EMP. 

I tested on a Turnigy Plush 40A ESC as HK suggests this motor has a max current of 34A. I think from the numbers I got and also confirmation from Airflow on the RC Powers forums that I will be safe using a 30A ESC from now on to save myself a little bit of weight.

The battery I used was a 3S 30-40C discharge

Here are the numbers -

6x4 APC prop at 50% throttle -

• ESC at low timing - 14.4 A/168W/500 gr/17.6 oz of thrust;
• ESC at medium timing - 13.2A/153.1W/450 gr/15.9 oz of thrust; and
• ESC at high timing - 13.8 A/164.7W/480 gr/16.9 oz of thrust

6x4 APC at 100% throttle -

• ESC at low timing - 26A/280.9 W/720 gr/25.4 oz of thrust;
• ESC at medium timing - 29A/335 W/750 gr/26.5 oz of thrust; and
• ESC at high timing - 27A/299.7 W/745 gr/26.3 oz of thrust.

6x3 EMP at 50% throttle -

• ESC at low timing - 13.1A/156.3W/550 gr/19.4 oz of thrust;
• ESC at medium timing - 12.7A/148.8W/535 gr/18.9 oz of thrust; and
• ESC at high timing - 15.2A/182.7W/570 gr/20.1 oz of thrust.

6x3 EMP at 100% throttle -

• ESC at low timing - 26.8A/317.4W/870 gr/30.7 oz of thrust;
• ESC at medium timing - 23.6A/261.7W/860 gr/30.3 oz of thrust; and
• ESC at high timing - 23.7A/262.4W/860 gr/30.3 oz of thrust.

6x4 EMP at 50% throttle -

• ESC at low timing - 13.6A/159.2W/550 gr/19.4 oz of thrust;
• ESC at medium timing - 13.7A/159.5W/560 gr/19.8 oz of thrust; and
• ESC at high timing - 14.7A/177W/560 gr/19.8 oz of thrust.

6x4 EMP at 100% throttle -

• ESC at low timing - 25.5A/298.4W/835 gr/29.5 oz of thrust;
• ESC at medium timing - 26.3A/305.9W/860 gr/30.3 oz of thrust; and
• ESC at high timing - 25.5A/287.5 W/840 gr/29.6 oz.

This is another small motor that seems to really like the 6x3 EMP prop from a standpoint of thrust and efficiency.  The thrust numbers are slightly lower at medium timing setting, but overall efficiency especially at high throttle are much better than at low setting, so I think I would run this motor on a 6x3 EMP prop and a 30A ESC and it would be a great power combo.

I also did a walkaround video yesterday on my newest Mig29 V3 to discuss my build techniques, etc.  Here it is.

For my next build I am considering another FRC Foamies F35 600, I just love that little plane, I am going to build it as light as possible and probably try out the RC Timer 2212-6 2200 Kv motor in it on a 30A ESC and 1600 Mah battery, I think that would be a good power setup.  I will again activate all control surfaces, but I think I will do something a little different with my vertical stab and rudder setup over the previous two I built with full controls.  Paint job will probably be in Vancouver Canucks colors since hockey season starts this week!  WOO HOO!  GO CANUCKS GO!

Cheers,

Scott
