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!!
