The 4mm ones use the little round slitted spring contact thing right? I'm not too fond of that style either, it does seem to work well though.
You slide both wires through the plastic sheath, tin the tip of the wire, tin the connector, touch your iron to them to melt the tin'd spots together, then hold the plastic body and yank backwards on the wires, and the pins seat into the connector. Takes me about 1-2minutes to install one. If you don't have the plastic sleeve all ready on the wire and you put the pin on, you need to unsolder it and put the plastic over the wires first, you can't force it through the back without mangling the plastic.
Glad you've got a boost

The soldering pencil looks good. Quality is impressive for $6. In my first use with #10 wire and 4mm bullets it did the job. Not as fast or easily as I expected. I'll hold judgement until I get more experience with it.
On the 4mm Turnigy bullets. I'm not impressed with the wimpy little spring contacts. Yes there are a few in parallel, but they don't have much current carrying cross section. We'll see how they do.
On the two pin bodies, how does one get the pins into the body? They don't want to push in from the back, and the hole is too small to take 10 gauge wire insulation through to solder them beyond and pull back. The 4mm terminals will accept 4mm wire, which is more copper than #10, so the fit is not great. Not sure yet how to make them work. I'm sure someone else on here can tell us how the insulator body should be installed.
On the whole, I have no idea why folks want to use soldered bullet connectors. It is absolutely a pain compared to crimping a proper connector with a good crimper. No wonder I haven't soldered a single Anderson since I got a good quality crimper. It has been so many years I forgot how not fun soldering them was. I jumped at the chance to buy a good Anderson crimper for only $50 after soldering them for years! These bullets have no decent mechanical grip on the wire. Their solder cup is very shallow. Solder wants to wick up the wire making it stiff. It takes time to heat them up. It is tricky to get a nice joint. It takes time to wait for them to cool. What a royal pain.
