so i found the lehner site last night and was thinking that the 1950 was closest to a 1521. they look pretty sweet. the 1950 is the same length as the Castle 2200kv Neu - 74mm. anyway, the main reason i was wanting to get the larger motor is for weight distribution. i wanted to get one of these 6600 mah TP lipos
http://www.robotmarketplace.com/prod...600-5S2PX.html and would need a heavier motor than a 1515 on the other side of the chassis to balance things better. my 5000mah does pretty good, usually 20-30 minutes but i went bashing with kulangflow and he was running 8000mah packs and wasnt halfway through is charge when my lipo was done. just thought it would be nice to have the longer run times but maybe i will just stick with the setup i have. other than more run time is sounds like not much would change. thanks guys for all your help.
anyone know how much the Castle 2200 weighs? the Neu 1515 finned weighs 12.7 oz or about 360g and the 1521 weighs 16.93 oz or 480g
