I am a little confused by what starscream was trying to say in his earlier post. But here are some tables that make for some interesting reading
Lehner BASIC XL 1200,

Lehner BASIC XL 3600,
http://www.lehner-motoren.de/diagram...6.7v_liste.txt
These 2 links show data from lehner's website. Both motors are doing 21-24krpm. One can cleary see that the XL 1200 is a good 4-5% more efficient than the XL 3600, it has about 50% more torque, and 50% more power (output). Lastly the XL 3600 is pulling double the current of the XL 1200 ( and yet the XL 1200 has 50% more torque!! ). I hope these figures prove to everyone that slower turning motors are more efficient, more powerful, far more torquey and draw much less current.
Ps. in the links, you see the bit that says 'basxl-12.18v' and basxl-36.7v', do you think that they are the more accurate kv ratings of the lehner motors. ie the XL1200 is infact 1218kv and the XL3600 is infact 3670xl? Seems likely......
