Marco
That ought to fix the arcing. Before you go to the trouble of mounting them in tank test them with the battery on the bench. They should run fine direct connected to battery. I cannot remember...

Mark/Jerry
That is great news. A scratch built metal tank in Any scale is worth salvaging! Good work! Motor wires arcing to metal body would definitely cause some smoke! Great to hear nothing is...

Marcocaster - Sorry things did not work on this for you as planned. Like the others said tho - Don't give up on it. If the model is mechanically sound - and it appears to be on the outside - then its...

Marco
I think 50A is too much. Your motors run around 5A, with a Max of 8-10A, So I would fuse your track motors about 8-10A

As for the Sabertooth it has overcurrent protection built in. But...

It doesn't hurt to have extra amp handling capability in the ESC - esp at same price. I'm using the 2X60 in my Stuart which is probably overkill - but it has been flawless performance wise. I figured...

Sorry to hear about that. There could have been some defective components in the ESC which caused it to fry. Overtime (especially 20 years) components can go bad. Buying something used we...

Do both motors run ok both forward and backwards hooking them direct to battery? It may be a ESC compatibility issue with the radio. You should be able to switch the Vantec from one stick drive to...

Marcocaster
Try switching the leads from the Vantec to motors. If problem now moves to other side (left side only runs in reverse) may not be ESC. Test motors with just a battery as well - do they...

Mark,
I've heard this problem occurs only with Spectrum radios. Haven't had trouble with mine yet. Surprised adjusting the trim didn't resolve it however.

Its usually something simple if it doesn't work. I solder all terminals on the wires (even though they are crimped etc) to avoid the dreaded partial intermittent connection. 24V motors will...

Jerry,
Totally agree with you - I think your Amp range (5-12) is probably correct for the JP in question. Its difficult to determine what is correct on older motors with no specs.

I made a few redlines. The redlines are similar to how I wired my tank drive motors, but my track motors are 1/4 HP each and 80A @ stall. Your 1/10 scale will be smaller power/amps. I'm also...

You will want the biggest gage size wire from the batteries to the buss-bar, main switch, and power into the ESC. The wire for the motors can be smaller. What is the amp rating of your...

Electronics have changed a lot since that model was built. The only reason I can see to use a six way switch would be to activate 5-6 things at once via a mechanical switch on/off. Or...

Can you share where you got that slick resettable 100A switch / breaker? And the heavy duty bus-bar? I've looked high and low for something like that and not found any like it. Those are very...

Marcocaster,
I'm not sure you need a 6 wire switch. But you do want to break the red power wires with a switch. I have had good luck with the Hella marine 100A

Very nice find indeed. That is a very well done model. Actually 1/10 is quite popular in Germany, a few places sell parts and components. Definitely not that popular in US. It is a great scale for...
