Default Soldering is a Bi!#¤

Why is soldering still in this hobby!?

Why has there not been made clamp and a screw connection on the motors and esc?

Ok. I understand that you might save some milliwatts by soldering your competition car but for everyone else who is not so serious or is not racing a boltet connection should be plenty good.

Sorry, move thread to here please. This forum really need a delete option some time after after you post it.

Soldering is easy. But you need a decent soldering iron. It makes all the difference in the world. Get a crappy one and even someone who knows how to solder well will have issues.

You could get his system: reflexracing.net/QTEQ-Power-Terminal-Motor-Connector-Set-LV-Type_p_1058.html

You'd still have to solder that to the motor/speedo.

Its a step in the right direction.

I ended up just driving to my local RC shop and ask them if they can do it. i need a more powerfull soldering iron indeed.
40W is not enough. 60W or more.

Personally think i would have been able to do it with a tiny torch.
Heat it and quickly add tin. done. I also need a bunch of gripers.

I envy octopuses..

Good heat and zero pressure. I have great luck with my Hako 936 iron.
I love the guys that smash the chassis flat to the table when trying to undo some motor wires.

Yes wattage is important but technique & tip go along way. I use a 3/16 flat tip for most things. Wipe the tip on a wet sponge to get the tip clear, apply a little solder to the tip -should be shiny- this helps transfer the heat. Pre-tin both surfaces. Hold the iron in one place and paint the solder on from the other side, it will be drawn to the iron. A little flux sometimes help. If you pre-tin, may times you won't need any more solder to join the two items. Heat the larger of the two pieces first then add the second. You just need a fillet, not a blob. Fast in and out works the best. Good luck.

40W is plenty. I use an 18w for most soldering. I like the 60 watt to de-solder. I find the 60w gets too hot, the solder moves to fast and just seems harder.

Have somebody decent show you how to do it. After I watched my friend give me a quick lesson it seemed much easier.

Hi mats

I have for now 20 years used my 50w weller solder iron , its the one with magnetic tips. I know its a expensive one , but you have it for life. Everything can be changed with spare parts. I use a #9 tip and as wide as i can get ,think they call it a "screwdriver tip" with that one i have soldered many packs together back when we were using sub c cells. Another importent thing is the solder tin , buy the good stuff from a electronic shop and not the thick one from your local bauhaus

From an electrical standpoint soldering is best as it introduces less resistance in a circuit.

Less resistance = less heat = less wasted energy

MatsNorway, check out a more in depth look at the QTEQ Plugs in this thread. Yes, you still have to solder, but it essentially is one and done. Since the plugs are 24K gold plated and they are screwed on, the pressure between the connection is much higher than "spring loaded" connectors, this leads to much lower power loss.
