Big Al,

I had the same intermittent issue you described a while back. Drove me nuts, I tried everything... Someone from Tekin Tech Support told me it was my servo. I put a new servo in and have not had a problem since.

May not be your problem, but if you have access to a spare servo, it might be worth a shot.

I've been using this servo for about a year now, suppose it's possible. Just to clarify, It's not just the receiver and servo that stop working, the esc literally loses power. All leds are off. Went through all the connections just to make sure. Also, about a couple of months ago I accidentally spilled quite a bit of paragon fxII onto my chassis and electronics. Would that cause an electrical issue? I've cleaned out the receiver case and esc case as best as I could(took them apart), but I suppose some could still remain.

bigal, are you running ANY heat shrink on your solder posts on your RS?

If anyone is interested in a great deal on a netbook to use their hotwire on check this out:

Negative. I took special care to make sure nothing is close to or on the posts. As far as I can remember, this problem didn't arise until my paragon fiasco. Feel free to chime in people!!

if issue is related to temperature, check your wires and batt connector if they are heating up. If your wires have a bad connection or have deteriorated, they will heat up to the point that they will not be able to supply the amperage they were originally rated to. Add the ambient temp to your already hot wires, heat = resistance and if you have too much heat, it may be the cause of the current dump you are experiencing.

My guess is that you have some sort of internal problem. Semiconductors capacitors and resistors usually cause these impossible to replicate problems. Over time these become permanent.

If everything outside checks OK, I think the next step is to look inside the speedy. Unfortunate.

I had a problem awhile ago where my car just stopped and then did it intermittently from then on, finally found the connection (Corally plug) to the battery had been arcing and the slightest movement would turn the car back on. long story short changed the connection and problem solved.

Cheers

bigal- had the same thing when 203 first came out on 3 of my cars. All same servo. Few locals all changed servos and stopped their issues, I kept my servos but had to put a 3300uf or higher cap on the receiver. Never a problem since. Seems the cap smooths out the power so no dips causing the esc to sense this and shut off which kills the power to the receiver. Switch to a spare servo(different brand, seems Ko servos had the most issues) and see if it goes away or try a cap if you have one.

If you bathed your RS in paragon that's not going to help. However you should have been able to blow it out with some air after uncasing it and as long as you got it all out it should be ok.

Check your servo like the others are stating. Also make sure you've got solid battery connections.

What brand/model servo, that works fine with every other esc, are we talking about giving problems?
