i did go and call them today and they told me to find out which is bad, motor or esc. so im doing that at the lhs this weekend and then ill be sending back whichever is defective.

Does anybody know how many amps the vapor ESC is?.... Or was

spena

if the vapor esc was based on the mmp thenit should handle 120 amps continuous and have been tested to 300 amp burst setups, according to someone in ultimaterc

billymare

it looks like a sv2 to me...

Anyone fix the loss of range yet with these trucks? Seems like I go about 50 yards or so and my truck is dead on the water. I have to walk to it for it to move anywhere and such. Any suggestions for this?

Check the antenna wire it may have gotten caught on the rear center drive shaft causing it to rip apart.

starjammir

Already got a new antenna wire on there today so I don't believe it is that.

What do you mean? Did you replace the existing antenna wire that was on the receiver?

Computer was broken and I wasn't able to go on here for a few days. I am starting to realize that ESC amperage ratings are about as truthful and accurate as nitro engine HP ratings. The amperage readings I saw in this thread earlier (it was just one rating but the guy that posted it wasn't a dummy) showed 140A or so under hard acceleration for the stock motor and 110 amps for what I think was an SCT 3800 motor.

I wouldn't recommend anyone using the stock ESC at this point. This truck is best sold in the kit form.

What did you use to replace the stock antenna wire?

no need to buy a new reciever just solder a new antena wire

I'm looking to get this for a niece of mine. She's 7 and ready to step up to something a little bigger. But I don't want her to have all the power of the 2s. And it sounds like 7.2v nimh is only a little slower. Is there an easy way to limit the throttle without hurting the esc?

reut1

so upon further investigation, the leads going into the esc from the motor are starting to melt a little bit. heat shrink on the leads are gone and the case of the esc is starting to melt. so im prob gonna get a mamba max pro kit and send this stock stuff back to hpi to keep as a back up or other project in the future

Reut - you likely caught one of the weak ESCs that has the same problems but not as extreme, saving you the blue smoke.  I would take advantage of the warranty and use the replacement HPI sends you just in case it blows up.  Keep them on the hook.  Why get a replacement that will likely blow up as a spare since you will use it and blow it up after the warranty goes out.

starjammir

Hpi sells an antenna for replacement it is $4.00 at my lhs. That said mine broke like everyones and I put the new one on and still it sucks for range. It really seems like there is a huge delay too on the response of the car.

nitro-rob

Did you remove the wire off the board directly or solder onto the broken wire?

ThunderbirdJunkie is more interested in what wire he used...because if he used an AM/FM antenna, then his radio is not going to act properly.

Speaking of antenna wires!  My tube has come out, and so did the screw that helped hold it in place.  Also my wire has been worn down a bit and it dangerously close to the drive shaft.

What have you guys done to keep it out of the way, and the tube in place?
