ORIGINAL: Propworn No bearings or counterweight to eliminate or reduce friction for crying out loud
Propworn, Let me start with the bearing issue you mention. <span style="font-size: small">Would it not have been reasonable,for you to have first askedwhether bearings might be used in the Test Stand I have designed ? -<span style="font-size: x-small"> rather than just assuming that they are not ...?
</span>
</span>As you see from below,<span style="font-size: medium"> BEARINGS <u>ARE</u> USED ...</span>-They are 1/2in inner diam, 1-1/8in outer diam; Japanese high quality KLNJ</p>

I actually thought very carefully indeed about this Motor Test Stand design,and designed and built it over severalmonths -Also with the advice and input of Dr Kiwi, who has been testing brushless motors since 2004, and who has published probably well over 100 brushless motor tests -see: http://www.geocities.ws/dr.kiwitn/</p>

<span style="font-size: medium">So Propworn, we have tackled the first thing you mentioned-bearings. And we have shown they are of course used in the MotorTestStand...
