Executive summary- Michael's presentation- Oct 2 Pilots'Meeting

[Frank v B]

For those who were present at last nights Pilot Meeting and did not quite understand the impact of technology on electric flight......

Motor:  The Speed 400 size brushless motor* is now 10 times as powerful as its 15 year old brushed cousin for only a minor weight gain (.8 oz).
Battery: A new LIPO 7.4 volt 1800 mah battery weighs 3.2 oz.  A website lists a 6 cell (7.2 volts) Nicad pack at about 10 oz.

Can somebody please post the weight of a 6 cell, 7.2 volt 1800-ish NICAD PACK for comparison.  I can't find a pack in my shop.
Please note that in he early 90's, Sub-C Nicad battery packs were upgraded from 1200 mah to 1500 mah!  Wow!!
