Replacing ESC and receiver, how do I choose?
Hey all,
If you read my last post, you'll know I recently had my Losi xxxt drive itself into a puddle, frying some electrics. Thanks to some help from my last post, I figured the problem was probably the receiver. So I removed the receiver. I then noticed that the brown wire from my esc to my reciever had torn off the esc. So now I'm planning to replace the receiver and esc. I looked online and can't find the esc I have. How do I choose a new one? I don't know if it depends on the motor (stock for the xxxt), or the reciever (JR r125) or what. Thanks for any input |

Does this look like the ESC? http://www.losi.com/Products/Feature...rodId=LOSB9522

Not even close. My esc is small, black, has dean's connectors, and doesn't have whatever that curly wire is on that one. it's named the V3R by gm racing

Do you use LiPo?
|
RE: Replacing ESC and receiver, how do I choose?
If all that's wrong is the wire came out of the ESC, why not just solder it back on?

RE: Replacing ESC and receiver, how do I choose?
No, I'm not running lipos. <div>
</div><div>And I have some very basic soldering abilities, but not enough for this. It's a VERY small wire, a very small spot for it, and it's cramped with other things. Also, the wire didn't come clean off, it tore, leaving behind some tangled wiring. I don't know how much sense that makes but the point is I'm not able to solder it. Nor do I know anyone who can.</div> |
RE: Replacing ESC and receiver, how do I choose?
well, to answer your basic question, the answer is: it depends.
it depends on what kind of transmitter you have as to what receiver you need to get. They have to be compatible. That usually means you have to use the same receiver brand as your transmitter. (There are limited exceptions) I've been very happy with the Fly Sky GT2 trans/rec I got from HobbyPartz.com. For $20 you get a 2.4ghz trans/rec that works great, no crystals, no interference. For $40 you can get the GT3 with a 10-model memory and lot's of other features like end-point adjustments and anti-lock brakes. As for the ESC, it depends on what kind of motor you have, whether you still want to use it, is it sensored or not. I have no experience mixing ESCs and motors of different makes. You would have to know how much power your motor draws and buy an ESC with the appropriate amperage rating. Again, HobbyPartz has EZrun and Xerun ESC/Motor combos for very reasonable prices. Your XXXT I think is similar to my Evader in weight and layout. I am running EZrun 35A systems in both my evaders with 4300kv motors on 2S Lipo. Plenty fast for me. and each system cost me less than $100. What YOU choose depends on where and how you drive. Street-running speed runs or off-road bashing? |

Thanks so much for the help EXT2Rob.<div>
</div><div>I'm kind of in between racing and bashing. I don't actually participate in races, but I like speed. Also, I don't completely wreck my car, but I do rough it up a bit. I found the receiver I currently have online, so that's settled. As for the ESC, I decided to replace my motor and ESC together (the motor has some serious use out of it, and can't have much time left). I was thinking about this:</div><div> </div><div>http://www.ebay.com/itm/SKY-RC-Leopa...ht_4730wt_1278</div><div> </div><div>Opinions? I'm running an Onyx 5000 mAh 8.4v </div> |

That would be a good combo for your setup, go for it.

And shipping is only $3.99. Plus, the combo you were looking at on ebay will come directly from China, so it will take forever (a month usually) to get here. This will come from Illinois: -ESC: http://www.valuehobby.com/power-syst...ezrun-60a.html -Motor: http://www.valuehobby.com/power-syst...or-3190kv.html |

Thanks a lot guys, I'll go for the ones Huntingterminator recommended!<div>
</div><div>Btw, this is random, but why not ask here instead of a new thread. What is the classification thing for batteries. People say 2s or 4s, etc. what does that mean?</div> |

RE: Replacing ESC and receiver, how do I choose?
I have 2 onyx 5000 mah lipos for my proboat, but they're significantly thicker then my nimhs, so I'm not sure that they'd fit

RE: Replacing ESC and receiver, how do I choose?
That shouldn't stop you. There are a number of folks here who've come up with clever ways around that issue. But I'm surprised your 5000mah Lipos are "significantly" thicker than the NiMh pack. Oh, and 2S, 3S, 4S, etc, not only is the number of cells in the pack, it also, obliquely, refers to the pack's voltage. 2S is 8.4V, 3S is 11.2V, etc.
|
RE: Replacing ESC and receiver, how do I choose?
Hahaha, I'll have to figure out something. So if my LiPo is 7.4 V, it's...less than 2s?
|
RE: Replacing ESC and receiver, how do I choose?
Oooops......my bad. Yeah, even tho a LiPo is rated 7.4V, it charges up to about 8.4V. A LiPo is discharged when it reaches about 7 volts. Rule of thumb: you don't want to discharge a LiPo below 3.2V per cell, 3.4V for safety margin, or 6.8V for a 2S Lipo. If you go below 3V your LiPo battery is damaged and should not be recharged.
|
RE: Replacing ESC and receiver, how do I choose?
Is the only way to check that using a voltometer
|
RE: Replacing ESC and receiver, how do I choose?
Lipo is simply 3.7v per cell nominally and fully charged 4.2v per cell. When buying, you want to use the 3.7v per cell rule to figure out what you are buying.
You don't need a voltmeter, but a multimeter is never a bad investment. |
