Sorry, but I was so happy to see you get frustrated while soldering connectors. I end up yelling like I did 30 years ago when I started working on cars. There a fine art to soldering for sure

@richarddegrace4557 7 месяцев назад

Scott one thing to note. With solid wire the electrical field flows around the wire. With stranded wire the electrical field runs through the wire. Most of the stranded wire is aluminum. Try using Rosen core aluminum solder. This will make a better conducive connection with less heat. You don't want to heat and break down the wire jacket. as far as separating the wire, try using some automotive plug wire insulator clips.

@M5PerfHydros 7 месяцев назад

Oh I hadn't thought of using aluminum solder. Or more correctly, I didn't know that was a thing. But yes I'm familiar with how those little electrons prefer to travel, and even with stranded wire they continue to travel around the perimeter, but the beauty is there is more perimeter area upon which to run in stranded wire. This is what bothers me most greatly about soldering in general. Presumably they (those little electron buggers) travel only along the outside of the solder, which then effectively becomes a resistor. This then becomes heated as they get frustrated in their travels, only compounding the problem. So... What then is the best possible method of connection?

Trick to zip tie bags. Cut a slit down the middle of the bag shorter than the zipties. That way they can slide out and they're easy to pick out. My Dad thought me that one.

@jefferyferguson9232 2 года назад

next time twist the wire in the opposite direction of the original twist. you want it to fray. work rosin flux into the wires into the original twist direction. it will then work into the core. make sure your solder joint is shiny . that's the way we did it on titan 2 missile wiring .

@M5PerfHydros 2 года назад

Interesting!

@jamesfackenthal 2 года назад

Believe it or not, Volts and current going to The motor are converted to 3 phase Alternating Current in the ESC. And by reversing 2 of the 3 wires, it reverses the tractive direction of the field windings changing the direction of the armature. Without changing any of the built in timing between the armature and field windings.

Get yourself or build yourself a “The Jigs Up” soldering tool. It will hold everything you are doing firmly. And like was said before...I used kester 60/40 and I take all wire but especially the heavy battery wired and work some flux into it really good before tinning and I also use some on the connector and tin that first with it before making the connection.

@stevesballisticrc8770 3 года назад

I use a little flux when solder my connections. Helps the solder stick.

@remkojerphanion4686 3 года назад

For soldering those large connectors, I use a heavy old-school soldering iron. It takes ages to warm up, but it has such a large heat capacity! It heats a big connector and those fat leads up in like 3 - 4 seconds. Boom, done!

@M5PerfHydros 3 года назад

Nice!

@georgegonzalez9281 2 года назад

A small butane torch works best for soldering bullet connectors - especially for those big 6 to 8mm honkers. Thin gauge solder melts faster too. Love your channel!

@M5PerfHydros 2 года назад

Thanks George!

@jjh.rc.videos8863 3 года назад

You can wipe the solder iron tip on a wet paper towel or sponge before you solder, cleans it for a nice connection/heat transfer. Don't know if its easy to remove the liquid tape if you need to re-solder. I usually put a smaller diameter heat shrink wrap at the base of the wire, solder connector, slide shrink wrap back up to connector, then slip over a larger diameter shrink wrap over the 8mm connector. Then when you heat to shrink it, you don't have trouble getting the large diameter shrink wrap to shrink enough to grab the wire, it will grab the smaller size shrink wrap for a nice fit.

@timstebbins6295 3 года назад

Good video Scott! Very helpful on how to connect everything up. Thanks.

@M5PerfHydros 3 года назад

Glad it was helpful!

@InspGadgt 3 года назад

Over time those types of connectors get compressed. You'll see the gaps in the male end get more narrow. The connector relies on some spring force to keep a good connection. When they start getting compressed you get a loose connection causing arcing and heat in the connector. It's a good idea to periodically check the connector and use a thin flat bladed screw driver to open the gaps back up and provide that spring force to keep a good connection.

@M5PerfHydros 3 года назад

@protator 3 года назад

zip ties are a good solution for more permanent connections like motor-to-esc ... in models with a single battery pack I also make the wires different length. I usually shorten the battery's negative and the esc's positive wire by 2x connector length and tape the battery's wires together ~ 1" behind the short wire's connector. This way it's still easy to connect/disconnect them, but physically impossible to short the battery pack.

@rhipp100 3 года назад

I use bow string rosin from a music store or by the commercial liquid rosin, put your gun in the rosin to heat it up and dip the wire into the melted rosin then tin your wire add a small amount to the connector also, it will suck it up no problem. Cleans the wire, connector and gun, Good stuff trust me so much easier.

@M5PerfHydros 3 года назад

@bigharrykochenbauls4567 3 года назад

Use a separate Flux for tinning solder, plasti-dip (for tool handles) easier for the connectors.

@sailr 3 года назад

You should always use silver bearing solder on your battery and motor leads as it has a much higher melting point than standard rosin core solder. I have seen some high amp applications melt the solder and stop a boat in the middle of a race!

Yup!

@patruddiman4228 3 года назад

I have a speed master rudder when mounting the rudder bracket I used a square to align to the transom. Before drilling any holes i attached the rudder and it didn't look square to the bottom of the boat. I took the rudder off and noticed that the machined surface of the hinge for the rudder was thicker on one side causing the rudder to tip put of square. So should I use my angle finder to make the rudder 90° to the bottom of the boat?

@M5PerfHydros 3 года назад

Well that must have been pretty disappointing. An angle finder would probably work fine so long as the spine of the rudder is equal width top to bottom and you hold it carefully on that spine. Plan B would be to send it back to Speedmaster for replacement!

@pcooper985 3 года назад

Great Video. I was hoping you would talk about the cap bank on the ESC. Like the proper way of wiring it in . You've set up for series on the batteries. Does it matter Series vs Parallel on the cap bank on how it's wired or is it the same both ways?

@M5PerfHydros 3 года назад

I'm not an expert on the "Why" side of the capacitor question, but I do know a couple basic rules; Capacitors must be added in parallel and should be mounted fairly close to the ESC (within 1" - 2") on the two input wires only.

@sailr 3 года назад

Cap banks are to survive 'ripple effect'. That's when the prop leaves the water and then bites back in the amp draw can serious spike. The capacitors cushion the blow. They are wired parallel with the batteries.

@watchman1629 3 года назад

I think youre not supposed to use dielectric grease between the electrical contacts, just around them.

@M5PerfHydros 3 года назад

There's plenty of debate about that, and it's easy to find logical arguments for all opinions! Best I can do is go with what works for me.... I've used dielectric grease in sensitive automotive connections for literally decades as a career auto tech (recently sold our shop and retired, thank goodness), often solving connection problems with it's application alone. I first found it used in the multi-pin engine control module connectors in all the OEM vehicles starting sometime in the late '80's or so. Pin corrosion was a super common problem prior (computers started showing up in cars around '79 or '80) but was greatly reduced with the introduction of dielectric grease. So... I use it faithfully in all connections on my boats, and haven't run a radio box for years with zero (knock on wood!) failures!

@watchman1629 3 года назад

@@M5PerfHydros Point taken, Scott. Thanks for the videos and reply. I can see you certainly have a lot of experience with the hobby; sometimes whatever works is the best solution. You might see my point that putting a non-conducting grease between your metallic contacts may seem counterproductive, after all the pains you take to ensure optimal performance of your boat. May I ask....since you are adding the batteries in series, totaling over 30 Volts, what is the maximum voltage rating for your ESC and motor? Also how do you choose which electric motor to use? The Oxidene Marine website sells theirs for $150 and with ESC for $250. Are those reasonable prices? I was thinking of building a scratch nitro boat, but I have no knowledge about nitro/glow engines. Do you have plans for yours or similar hydroplane that I could download? Thanks again.
