Replacing stock setup

[xkos]

Tomorrow will try neu 1518 (2340kv) with 4s2p (10000mah total) and m545, and 5s2p (9000 mah total) with x642.
Can anyone estimate amps draw? I have a swordfish 200amp esc.
thanks.

how fast do you want to go mine hits 55 regularly on a leo 4074 2200kv a t-180 with a m445 prop and 4000 nanotechs 4s2p and i am going to try a 447 or a 545 maybe both as temps are good

I want to check if parallel connection can give me more speed than series. Yesterday i tried the 1518 with 4s1p (5000 25c - m545) and with 5s1p (4500 25c - x440/3) and the result was disappointing, 44mph on 4s and 47mph on 5s while with the same lipos and props and neu 1415 2200kv the speed was 47mph on 4s and 53mph on 5s. I'm sure that i need lipos with higher C ratting.
