Well if you are shopping at HK then why not go for the Funfighter motor at $9.99 http://www.hobbyking.com/hobbyking/s...dProduct=24497
. Similar weight to the 2408-21T and I'm getting over 10 mins of mixed flying on a 1300 nano-tech 45-90 c 3S pack http://www.hobbyking.com/hobbyking/s...dProduct=18207
. Or you could go for the parkjet standard motor http://www.hobbyking.com/hobbyking/s...dProduct=24239
which is available from the US warehouse. Go for a 6x5 or maybe a 7x4 prop with this one along with a 40 amp esc to give you some headroom but as always check out the numbers by using a wattmeter.
My FB is using a 7x5 prop and this 1800kv motor on his Funbat http://www.targethobby.com/hb2822-rc...p-4161589.html
from Target Hobby. A lighter set up with around 20 amp esc and 3S 1000 mAh pack
I doubt you would have enough room for a 2200 mAh pack and even if you did, the weight would hurt the performance.
