Do you have lipos for 4S or 6S set up ?

[eboat]

1521 1D 2900KV

I think you want a 6XL 2871 KV

[CornelP]

Yup! Feigao 540 6L, 4116rmp/V, max amps 102A,

This seems to be the right place for this question...i was thinking about building a MM that will hit 60+ i am on a budget of about 500 any suggestions? I would like to try a twin set up but a single would do and oh the 500 doesn't include the lipos is there a feigo motor that is close to the neu 1521 1d?

thanks scott, running 2x2s 30c 5000 flightmax (zippys)

was asked for acouple pics of my MM setup, thought i mite as well put them here

Looks neat and tidy, nice one! What packs are you running?

[ozzie-crawl]

i would have thought the same thing, i work for a electrical switchboard company and we have rolls upon rolls of diffrent heat shrink

[eboat]

Sorry it looked like it still had the factory shrink on it and not water proofed yet

[ozzie-crawl]

it is conformal coated, i usally only run for acouple of minutes at a time so no water cooling needed, if i do start getting some heat issues i will just add a fan

[CornelP]

If you waterproof and watercool, it will be bulletproof (almost)... Ran it sunday on Feigao 10XL, 45mm prop, 4S2P 4800 and it was barely warm

Looks good but you should pull the shrink off the esc and water proof it (I have the same one and have seen one that got wet at a club race and melted)

[bustitup]

Doesn't that depend on the esc? Some have cutoff set at the volts per cell, eg. 3.2V and some are set as a multiple of 3.2V X #of cells.

I was referring to how to determine HOW to choose the voltage cut off you would choose if the esc gave you a bunch of options

for instance the castle link gives you a list of voltages to choose from....the formula i presented shows you how to choose the proper one

Well on rc cars this how you figure it

There are 3,7 volts per cell so. A 6s lipo has 22.2 volts

So to figure cut off take the number of cells x 3.2 so in you case 3.2 x 6. = 19.2 would be the safe cut off

hi guys the whole thread got some great setups but has anyone try the 580motors from steven. i have got an 90amps quickworldwide.com esc starts at 6s can this setup be eff, props x440/442/447 i do my own prop mods/ s/b/det also cupping. speedmaster strut/5"rudder.could this range give 50-60mph.rreyes.

I think I saw a MM with a 580 and it was nuts!
