Heavyweight ESC's

[mattsdragons]

hi all

ive been looking at various specs of robots and ive seem a few different esc's used such as wotty 360, wotty 180, roboteq, sidewinder, 4qd etc

ive tried to find out prices and amp ratings of there and ive had success with some but not so much with others

it will sound tight wad (mainly since i am ) but i need to balance efficiency with cost but i really dont know what to go for since there is just so much choice so what could you recommend me?

Re: Heavyweight ESC's

Depends on what motors and gearratio/wheeldiameter you're using.

Re: Heavyweight ESC's

260mm wheels on bosch 400w (probably) but not sure on reduction yet

[maddox10]

Re: Heavyweight ESC's

Bosch 400 3400rpm@12V 50A

5100 RPM@18V.

13 or 14/1 gearratio

Sidewinder will do nicely.

Re: Heavyweight ESC's

[maddox10]

Re: Heavyweight ESC's

That was the old new-pricetag. $299.

Unfortunatly, Robotpower make's em on order now, and that's $499 the last time I looked it up.

Re: Heavyweight ESC's

Anyone know how much the Wotty's are costing these days? Looking at the Wotty 180EV or possibly the Wotty 100, though that might be pushing it a bit.

Re: Heavyweight ESC's

last i heard wottys were £290 for a 180, £360 for a 360 but best to ask Ian. I would go for a wotty over anthing else at the moment. Roboteqs are too expensive to get fixed (~£170), Sidewinders are abit too close to their limits and as far as im aware you still cant get Vantecs fixed.

Re: Heavyweight ESC's

Why do people use the 360 when the 180 can take 90a?

Re: Heavyweight ESC's

Because The 360 can take 160 amp
