3004 is similar to 3001... its basically a ball raced 3003 !
ok i still don't get this direct, indirect drive stuff. the motor drives a few cogs till it reaches the output, whats indirect about that? in which case i've never seen a direct drive servo with the output on the motor it's self.
i've got two hydride battery's in my planes, the Pheonix has a Overlander 1400 one, and if you leave it for a week you have to put 1000mAh in there just to fill it up, the Ripmax 1850 in the Capiche seams to hold it's charge and not go flat quicker than expected.
What amazes me is when i first started out i had a 5 servo funfly, i'd fly all day without charging on a 800Mah pack, a friend too on his plane. but we never had a flat batt problem, these days now we have checkers we peak before going out, and sometimes do again during the day!
sames true with the cars, 1200 packs were the order of the day back then and we lasted 5 mins easy with cars very much less efficient than todays tourers. weird..
