Honestly I would go with the 4000kv motor , it is just as fast as the pro-4 4600 with more low end smoother and runs cooler. Very nice motor you wont be disapointed.

Ok thanks I will have to try it next time I ordered the 4700 combo this time so we'll see how it does.

you could do that on condition your receiver and servo can handle the 7.2V.

Most servos are 6V servos and will eventually die if you give it 7.2V.
Also, dont forget to remove your red wire from the ESC cable going to the receiver. this is voltage from the internal BEC of the ESC. A nice trick so you do not have to snip the red wire out of the ESC's cable is to get a servo wire extender and take the red wire out of that. This way when you need to plug your ESC to your programmer you dont have to worry about putting back the red wire.

Most of the hobbywing ESC's have 3amp internal BEC's which is current enough to run the servos and receivers. there are a few servos which tend to draw more current than others. Savox servos I have used in the past are an example. Plug a glitch buster into your receiver and you should be fine; in most cases you would not really need it but in case you experience any brown outs this is a fix. The glitch buster is nothing but a simple capacitor and all it does is stores charge; when the servo draws too much current instead of loading the BEC the current is supplied by the glitch buster.

Nice answer Rohan..............next time leave your name so people know who you are..................

Negative boss. Already tried the glitch buster and it still would have intermittent glitching.

Wow installed the SCT Pro and 4700kv in my SCTE yesterday what a power house and no BEC needed love it! We'll see how it runs in our Reedy Memorial SC points series this weekend.

I have a hobbywing 150amp xerun esc. The question is, will i need an external bec? I'll be using a hitec 7955, 1900Kv motor, futaba 2104GF reciever, and 4s batteries. Had problems with the esc in my 4wd sc, but that was when i switched to a different radio, and i've heard the 150amp doesn't like 2s setups. I figure i won't have glitching problems with a 4s setup due to the higher voltage, like the esc was designed for. Should i need an external bec, or will i be alright? The stock internal bec is rated @ 5.75 volts, and 3amps. Is that enough?

On 4 cell, no, you won't need an EXT BEC. I didn't need on on 3 cell either.

I don't remember who was asking but I have an answer on how to UN-solder the wires from the speed control. The user could not get the wires UN-soldered. I suggested that the user get a hotter iron and he said it still did not work, What you need to do is cut the wires off as close to the unit as you can then the wires will no longer act as a heat sink and they will heat up easier. I had the very same problem and after cutting the wires off it was much easier.

Hi Guys. Bought a used xerun 120 v2.1 and 5.5 combo. Didn't come with that capacitor. Is it necessary? Is there an aftermarket part I can use instead? Will be going in a b44.2

Any issues on the 150 amp XERUN 1.8 esc?

Its absolutely the best 1/8 esc you can buy. Its reliable, powerful, tuneable and inexpensive!

I finished 2nd after triple A/mains with my 150 amp speed control today in my Tekno eb-48, great speed control.

It's better/safer to use one

You find them in many shops and on ebay (search this: super capacitors module)

I have a fresh 120 A v3 esc & the fan has failed with very little use , is this common or is there a better replacement ??

Thanks
