Savox Servo causing ESC to cut out

[mikeyscott]

Hi,

I've just fitted a Savox servo into my B4 and when I turn full lock to the right it cuts drive to the motor. I have reduced the amount of avaliable steering in my KO EX-5 Radio and the problem seems to have stopped. Any reason why?

It's plugged into a LRP Super Sport Digital ESC.

Crap BEC on the speedo causing it to cut out under load (of full steering lock).

Oh bugger, so what do I change to? Looking at an LRP 7.1 on ebay, would that fix it?

I have a 1001 KO FET in my spares box, so that as well?

Got a Tekin 700 Pro Plus in the box too

I've assumed that, but it stands to reason, a lot of the budget ones have low voltage and low current BEC's to save space/money.

If that is the issue then your options are, different speedo, different servo (a 7.2V servo would irradicate this problem and is one of the reasons I run a KO 2123 in all my cars) or a 'power cap' for the receiver. Something like this, http://www.shopatron.com/product/pro...=NOV5626/135.0 which will keep the voltage high enough in the recevier to stop it cutting out.

I had the same problem, as I was still running old skool 27 mhz. Then I tried a Novak XXL receiver and it sorted it straight away. So it does seem like cheap receivers can't handle it.

Mm, I am also running my 40Mhz AM KO Propo Reciever from back in the day. It too is circa 15 years old. What 40Mhz AM recievers would people recommend?

Also sounds like my Ko 1001 FET might be going back in the car after all...

That won't work as I've only got two inputs on my receiver

So what is the best thing to change -

1) The speedo?
2) The receiver?
3) The servo?

I'll prob give DMS a call on Tuesday, but I didn't particularly want to part with my 40Mhz AM Ko EX-5 radio
