brushless 1/5 4wd conversion about to begin! couple questions.

I think it's just a bad joke, selling expensive esc's which just don't work. and bad service doesn't make it better.

but anyways. some months ago I was about to buy one of those esc's:

My first 5s bl-esc had the same black programming box like that one. So I guess it has a "kind of" car-program. using that box was just so easy. great stuff. But, I didn't use one of the esc's shown above. you probably could use the car brake of that esc. maybe you add some caps to be on the safe side.

suppo used to have a super high voltage esc, but their HP is down. Just because it's "no-Name" and chinese, doesen't have to mean it's rubbish. As you see, you buy "brand" and it's not working at all.

I used to have a plane esc similar to that one http://www.bidproduct.com/part/Produ...20ESC_106.html and it was rock solid, worked absolutely flawlessly. Only problem is, they have no dynamic car brake, but that doesn't matter for you.

here's the suppo 10s esc, I am sure that they had a 100a esc:http://www.lightflightrc.com/HTML/pr...80A_HV_ESC.htm

further there are the etti boat esc, for more than 10s. They are known to be good, not that cheap like a suppo or a hobbywing. I had one, which smoked soon...

I don't know how high the amps are driving that big, bautiful car. using 10s, 100a could be sufficient.

ok, so here is the email i just got from castle. it appears it am just an inexperienced idiot. i knew it had to be something i was overlooking. what i dont get is why it didnt say this in the instructions. i guess becuase any boat guy, which is who this esc is for, would have known this without having to to be told.

quote from castle:

Ryan,

The ESC is opto coupled. It does not have a BEC to power the receiver. You must power the receiver and the ESC with a separate receiver battery plugged into the receiver.


end quote.


ok, so it sounds like i need a bec and a separate rx pack. lovely. at least its gonna run today. woohoo. fingers crossed. so, i want to make sure i get this right. i have only used a bec one time and it was a looong time ago. can some of you experts guide me through how to set this up. i have that little blue castle bec that was like $20. is that gonna work?

[florianz]

ooops...

well, w/out bec it won't work...

be careful with the ubec/external bec, it has to work for 10s. it also should provide enough amps for the big servos.

eg, the turnigy ubec/bec are quite good.
