Thanks, Wayne

free tiger tank for the one who comes as a zombie hotdog

Thanks for coming out everybody! It was windy, and cold but we survived. No sunburn either!

Alas it seems to be true and my tanks are not infallible. My T-34 erupted into flames before it's maiden battle... oh boy! I will investigate the cause and update those interested parties on what happened. 

If anyone has a source for better main power switches, please share!

The wind did not help today, it did seem like the coldest outdoor meets we have had

Thanks to Wayne for bringing the lunch.

That was too bad, I can sympathise, having had a similar experience, I will be very interested to hear of any developments with diagnosing the cause and coming up with a fix.

I thought of you guys today. You must have froze your A**es off. you and me both Jordan. I am looking for much better power switches too. I guess should seriously start looking...

12 amp 125 volt single pole rocker switches how many you guys want?

I know I only have grade 12 electronics but why would you use a 12 amp 125V switch? That is way to much resistance in a switch for the systems we are using isn't it. Electronic guys chime in please?

There is no resistance on the switch. I ended up using the 125v switch as well as they are better quality.

Hey, it was a long time ago O.K. LOL! But wouldn't the 7.2 volts 3amp (at the most) have a harder time pushing through the heavier copper that would be in these switches? I'm just asking!... :-) There is a reason the switches get smaller and the metal components get thinner and lighter as you reduce the voltage and ampereage isn't there?

Well there is resistance on larger surface you are right but not significant enough that it causes a problem. After two HL type power switch failed on me I decided to move off them as much as I can. You don't need to get a big sucker, just the small rockers would be good. Single pole is important too since part of the problem with HL one is that technically it is always on with one of the poles.

Of course if you buy one that has LED in it then you will have resistance......  :-)

I second what Mike says, What resistance? Actually the blades on the switches I use are bigger and I have never had a problem except that one time I super glued the switch on lol
The switch itself is about 5mm L x 2 or 3mm wide and maybe 7 or 8 mm tall. Single pole rocker switches.

As an fyi ALL electronics in your tank should be rated to handle 10 amps imho. Most boards push 5 to 10 to the motors( elev, rotation may take 3 to 5 ) but always with electrics I do double the needed ratings.
 A 7.2v battery can burst up to 30 amps

I thought it was a bit of a cool day for riding.

My T-34 burst up to infinite amps for a moment or two hehe

Hopefully no board damage, and I suspect there is not. Will update asap.

Did you for a second thought the Heng Long smoker is finally working before realizing it was the real deal ?

As I said in my earlier email;

Thanks for posting that.

That video was nicely done.

Too bad it was a bit cold and windy there today, but we made the best of it.

Looks like i also lost a wheel today on the panzer IV and it had to be one of the tiny ones. IDK can you order the metal ones in singles?

Can we forget about mounting them into the former HL switch cutout under the tank?

It'd be nice but I'm going to assume a much higher rated switch just won't fit there.

I managed to jam one into one of the openings in my Leo. I think it is the opening for the smoker switch maybe ? Since somehow the smoker switched ended up on the old frequency switch pre-RX-18.

Failing that you will be better off with a round toggle since you can drill a hole anywhere you need and then Bob's your uncle, but for square ones you can definitely steal one of the openings.

This switch is for my Devo FPV only so it also can take higher voltage battery up to 12V but it is all the same.

Jordan  I regularly put these switches in the side door turret openings for the PZ111 and PZ IV. They are not big by no means. You could put these in the BB spot on turret hatches no problems. Since they are single pole they go down to the SW port on the Clark board

I like that switch installation.


A question for those with more electronics knowledge (just about everybody    ), since I had power wires fry and two other members have had the same thing happen, is there any benefit in installing a fuse in the system?

A lot of guys on the forums talk about inline fuses so I think it would be a good idea. Sounds like a good winter project to change over all my tanks to new switches with fuses! :-)

I am sure the fuse rating is important (too light and it would burn out all the time, to heavy and something will fry elsewhere), anyone have a suggestion as to what that might be?

Jordan's T34 fire on the 26th was a wake up call for me, if it weren't for some quick moves, it could have gone a lot worse

The only problem I see is that it could get bumped into a rock or something and turn it on/off but I don't run my tank that rough usually. I ran the Leo last week at a RC Off Road track and didn't have any issues.

The only time I ever fried a board is with my own stupidity with battery wires, or the HL switch basically connected the two poles together (Broken switch). With single pole it is either on and off and there is no chance of cross wires. Also, like Freaky says, with single pole switch you are actually using the Clark board switch connector and not a hack job off the battery in.

Clark site actually recommends that your wire it this way rather than the HL out of the box style (i.e. wire the switch off the battery feed) for high current draws like 400s/480s.
