<span style=''font-size: medium''>Quick note:</span><span style=''font-size: small''> Why have I chosen these particular 12T 30-size motors to test ?
</span>1. It may be thought that the Hacker A30-14L motor -a 14T motor with a Kv of 800 -is perhaps a more popular motor than the faster spinning Hacker A30-12L.</p>

2. However, for 14T motors, there are less motors to compare with the Hacker, than there are for 12T motors see: http://www.rcuniverse.com/forum/fb.asp?m=11427116</p>

3. For 30-size 14T motors -there is only really (in Europe) the: Turnigy SK3, Gens Ace, HYPERION, and perhaps the E-F Torque 2814T (more easily available in USA) -to compare with the Hacker 14T motor.</p>

4. Whereas with 30-size 12T motors, we have: Turnigy SK3, LiPolice LP, OK Hobby Infinite, HYPERION, Foxy, and also the WAYPOINT-E3020-12 972Kv to compare with the Hacker. <span style=''font-size: small''>-That is why I have chosen to test 12T motors, rather than 14T.</span></p>

5. There is also the additional intriguing issue that HYPERION claims a Kv of 900 for its Z3019-12T motor, whereas all the other 12T motors all have a Kv near 1000. Proper testing will reveal the genuine Kv of this Z3019-12T motor ...</p>


<span style=''font-size: medium''>So: Here goes: Lets have some action ..</span></p>

I have worked for years with the University of Windsor SAE Aerodesign students who compete each year in international competition. If the equipment you use for testing is as pictured it not in the slightest professional in any way. A simple lever on a postal scale, give me a break. Cripe the students do a much more thorough job testing than you could ever accomplish with that hay rube cobbled together junk. No bearings or counterweight to eliminate or reduce friction for crying out loud anyone can see the wiring the way it is unsecured to the apparatus is one more variable. All you have done is basic static testing through a lousy fulcrum hardly a controlled environment or testing to destruction and no dynamic testing through out the range. Even the students do this before selecting props, motors or battery packs. Hardly the work one would expect from someone who claims a clinical and professional background.
