Anderson PowerPole 45A and 75A Connectors – Amazing for RC Cars and Planes

Anderson PowerPole are the best connectors for RC cars, boats and planes

In the last couple of years I have tried a number of different connectors and I thought that I’d share my experience with one specific brand that has blown the competition away – The Anderson PowerPole’s…

I have tried the lot. For less demanding applications I have often used Deans, XT-60, EC3/EC5, Traxxas connectors and multiple brands of bullet connectors. For up to 300A applications I have used Neu bullets, Castle Creations bullets, the largest bullets from HobbyKing, Schulze connectors, Plettenberg’s largest connectors, etc, etc…

Then one day I cam across someone on a forum that recommended the Anderson PowerPole connectors. They are typically used in industrial applications but also lends themselves quite brilliantly for RC. As I see it the advantages are:

The absolute best is of course that no soldering is required and that they are quick to fit
Soldering will every now and then have a bad connection – but with the Anderson PowerPoles the connection is always perfect
If you are using an ESC without a spark eliminator system you do not have to worry as the spark on the Anderson Power Poles happen on the tip of the connector when you connect them and not at the actual area where they connect (it’s hard to describe but this is often an issue with bullet connectors and it makes a big difference in terms of the connectors durability and the quality of the connection over time)
You do not need heat shrink tubing
They are sturdy connectors and feels like they will last forever
The joint between two connectors is robust and will not disconnect accidentally (but unlike some connectors they are still easy to pull apart when needed)
Connectors can be stacked via a clever system
All connectors are identical (i.e. there is no male or female type of connector) and they are therefore perfect for connecting batteries in series
In my experience the nominal currents can easily be exceeded. Many use the 45A connector in applications up to 90A and 75A connector is seen used up to 150A and a few even 200A (do be careful here though!)

For some reason I have not seen many that use the Anderson PowerPoles and I therefore thought it would make sense to write a few lines about them now that I have had such a great experience with them.

Please check out my videos here of how they work:

Have fun!

Building a Losi 5ive-T Brushless (part 3) – Fitting the parts and testing the truck

When building this Losi 5ive-T brushless truck I had a set of criteria that I wanted to respect:

The car should have around 15-20 minutes of run time
I would prefer to have motor break and reverse option enabled
The steering servo should be capable = powerful and fast
All parts should be a-grade and have been put through their paces by other drivers (and with positive reviews)

I therefore decided on ordering the following goodies:

ZIPPY Flightmax 8000mAh 4S1P 30C batteries from HobbyKing
Hitec HS-1000SGT High Voltage Giant Torque Servo Conversion Kit for Losi 5ive. This beast deliver over 1500oz of torque!!
Killer RC Super Power Switch
RC Madness BL5 Version 2 Conversion

Here a few pics of the parts and mounting them:

The results

Before starting the project I had read tons of forum posts and seen many YouTube videos. I have followed most of the advice and chosen components that were all of high quality. Most however recommended the use of the Lehner/MGM combo and mechanical brakes but as you can see in Part 2 of this series I chose differently.

So how did it all go?

Well so far I can safely say that I am all satisfied with my truck and the decisions made. Batteries, ESC and motor have all been running smoothly with good temps and great runtimes. I have not timed it but I would think that I get at least 18-20 minutes run time on one set of 8S batteries.

The motor brakes (and reverse) have worked great. It may very well be that if you are a super competitive and very skilful driver there may be something to gain by having the (some say) better control using the mechanical brakes but I have had no issues whatsoever and love the setup as it is now. I have the control that I need when braking and love the fact that I can reverse whenever needed.

So for now I have had a ton of fun – building this vehicle has been a blast and driving it even more so.

If you have the funds and want to experience a brushless version of the largest 4WD RC truck on the market then you can’t go wrong with the Losi 5ive-T and I can definitely recommend the setup I have gone for here.

Have fun and drive safely 😉

Team Durango DEX8 – Fastet kit build ever!

I have built 1/8 buggy kits from Hobao/Ofna and Xray before I picked up this Team Durango DEX8 kit and hence thought this would be a somewhat similar build experience. I could not have been more wrong.

Just the unboxing experience is something different. The box and how it is packaged is the best I’ve tried so far with RC. They have no doubt tried to create an “Apple unboxing” experience and have in my view succeeded.

As for the build most of the parts are assembled in larger chunks. Diffs and shocks are all assembled (you will have to add diff and shock oil to match your preference) and front and rear drivetrain are almost also just a bolt-on. Very nicely thought through.

As for the build quality everything seems to be top notch but I have yet to test it out on the track. So far I have only managed to drive it up and down the street – everything was buttery smooth and only the steering needed to be slightly trimmed.

If I should have to point out something negative it would be the manual that came with the car. There were a few steps where stuff was incorrect – probably they wanted to get the product to market as soon as it left the factory. All it took was to download the latest version and here the issues were corrected.

Now – all I need to do is hit the tracks – Something I look forward to!

My Cellpro PowerLab 8 v2 charger – 2688W powerhouse in a Peli 1560 case

It’s been eight years now since I bought my first RC car. Since then I have had a ton of cars and planes and I have constantly bought new and better equipment. This however has not been the case with my Cellpro PowerLab 8 v2 charger. Why is that you may ask…?

Well the answer is simple – it is built like a tank, it has been working flawlessly and more importantly, there is yet to be a charger released that outperforms it in power and reliability.

My setup consists of the following:

2 x Cellpro PowerLab 8 v2 chargers – 1344W
2 x Mean Well SE-1500-24 power supplies
1 x Peli Case 1560

So… If you are looking for a killer charger that will refill your batteries faster than any other charger on the market and you want the best-of-the-best then this is the charger for you. I HIGHLY recommend it!

Traxxas E-Revo Brushless – The best all-round RC car money can buy!

Traxxas E-Revo Brushless 4WD Monster Truck

Through the years I have tried racing on tarmac, sand and gravel with everything from buggies to trucks and monster trucks. I have tried 2WD and 4WD vehicles powered by gasoline, brushed and brushless motors. All has been great fun and I have always enjoyed the great selection and thereby the versatility of this hobby.

A few years back I bought a Traxxas E-revo brushless car. My main purpose was to have something that was the “ultimate bashing vehicle” to be used in gravel pits. I had a long list of requirements:

It should be durable and capable of taking a solid beating when landing after big jumps
Spare parts should be readily available and not overly expensive
It should be 4WD in order for it to climb the big gravel piles and still make it to the top
It should come with a decent transmitter and not need a heap of up-grades before being ready to race
It should be fairly powerful but still have enough runtime to do bashing for at around 20 minutes on one set of batteries

Before the purchase I did a lot of research and found that all the boxes seemed to be ticked.

I had the car for around 12 months and drove it extensively over that timespan. Never have I put a car through so much and still had a car that just kept on going. Most of the time it was used in the gravel pit but I also tried it out on a 1/8 scale track and on tarmac only changing the tires to suit the surface. It stood out most when doing bashing on gravel but was aways a solid performer on other surfaces

But most importantly… I can’t recall I having had so much fun with as with the Traxxas E-Revo Brushless Edition. It is just THAT good and therefore I went along and bought one again after being away from RC cars for 2-3 years. A thing worth mentioning is that the car has had a few good upgrades in that timespan – the ESC has been made waterproof which was as a bit of a painpoint in the previous version and now it also features pretty solid telemetry if the transmitter is coupled with a smartphone using the Traxxas Link app via bluetooth. I have briefly tried out the telemetry and it seems to work well giving data such as speed, battery voltage, temperature and RPM.

As you can see from the pictures below I have bought the Traxxas Rustler VXL for my son who is 7 years old and I am also building a Losi 5ive-T brushless car that I plan to finish over the coming 4-6 weeks (waiting for parts to arrive from multiple hobby shops).

So all in all – this vehicle comes with the best of recommendations from my side and I look forward to having as much fun again with it as I did in the past!

Building a Losi 5ive-T Brushless (part 2) – Choosing the motor and ESC

Castle Creations 2028 Extreme 800kv brushless motor

Back in 2010 long before HPI released their HPI Baja 5B Flux 1/5 scale brushless car I made a Baja 5B brushless conversion using a big Schulze ESC and tested two different motors – one being a Neu 2230 and the other a Lehner 3060. This was a very capable setup and even though I really enjoyed the build and had fun driving it a few times I must admit that the setup was just too powerful for the car to put down the immense power to the ground.

Now with the Losi 5ive-T and 4WD it should be easier to get proper traction instead of the 2WD on the HPI Baja 5B that I ended up crashing. So in choosing the motor and ESC I made five decisions:

Start out with something that can be upgraded to more cells if I need more power but don’t start out like last time and “overdo” it
Build a car that works well on the track and for bashing – I will not be doing speedruns or something similar
Even though it will put pressure on the ESC I have decided to use the motor and ESC for breaking
Get something where there is a reasonable balance between price and quality/performance
Get something that has been on the market for a while and has been tested thoroughly (no cheap stuff from HobbyKing or similar)

The motor for the Losi 5ive-T

Having looked at the options today I got it narrowed down to three options for the Motor. The Lehner 3080, the Neu 2230 or the Castle Creations 2028 (which is basically a Neu motor just mass produced). My priority list would be the Lehner 3080 as the preferred choice but I ended up with the Castle Creations 2028 instead for two reasons. It has had great reviews on many forums, it is by far the best bang for the buck and I could run the car on a range from 8-12 cells which is what I would prefer to start out with (more on that later).

It is also worth mentioning that Castle Creations recently made some performance-enhancing updates to this massive motor:

Revised stator and magnet shapes provide lower cogging torque for improved starting performance
The new 800Kv rating will make the setup faster
Rated at a higher RPM (45,000) due to improved manufacturing processes
Capable of operating on 12S

Here some photos of the unit as it comes right out of the box including a shot with the motor on a scale and a size comparison to a Castle Creations motor in a 1/10 Traxxas E-Revo:

The ESC for the Losi 5ive-T

Finding the ESC turned out to be a choice between two manufacturers and both options had its pros and cons. One option was going with the highly praised MGM controller lineup. From what I can gather going over tons of YouTube videos and forums the TMM 25063-3 for Cars X2-SERIES PRO should be a solid performer and I have yet to find anyone stating that this has caused them issues or that has complained about performance. This ESC is capable of handling 15S and 250amps continous. The only downside is the price tag at around 610EUR with a few necessary optionals (fan, on/off switch, water protection, wiring).

The second option was the Castle Creations Mamba XL2 ESC. This speed controller is an excellent partner for the 2028 motor and is fairly priced at 171USD. This has also been on the market for a few years but with that said there has been issues with the unit and many have experienced that it went up in smoke. Furthermore there is an issue with the warranty and the fact that the Losi 5ive-T will probably weigh around 35lbs. Castle Creations write the following on their website:

“The Mamba XL 2 and 2028 motor are recommended and warrantied in vehicles weighing less than 25lbs for 4WD and 30lbs for 2WD. Any use outside of these recommendations may lead to an ESC and/or motor failure that is not covered by the manufacturer’s warranty.”

Also the Mamba XL2 ESC is only capable of taking up to 8S batteries but going back to my wish to start out and then be able to upgrade I decided that with the affordable price tag, the fact that they should have fixed most issues by now and that I have seen a few videos on YouTube where this setup is tested made me confident that this was the right place to start. This would also allow me to upgrade to the MGM controller if and when this should ever become relevant.

Building a Losi 5ive-T Brushless (part 1) – Stripping down the car

After having tried lots of different brands on the 1/5 scale scene – including HPI, FG and MCD – it was time to try something new. I had been away from large scale off-road cars for a few years and initially wanted to build a HPI Baja 5B brushless car but then found that there was a new sheriff in town – The Losi 5ive-T!

Many things with the Losi 5ive-T caught my eye. It was bigger in every way when compared to the competition, it was four-wheel drive, reviews on different forums were good, it seemed easy to work on and to do a brushless conversion and last but not least – it looked bad-ass.

So the first step was to get a hold of a Losi 5ive-T roller. Contrary to the Losi 5ive-T ready-to-bind model the 5ive-T roller comes without RC-components like servos, receiver, telemetry sensors, receiver battery, charger, engine, clutch and muffler – all stuff that I did not need now that I was doing a brushless conversion. I found one in Germany at an online hobby shop and paid €949 including a painted body.

Here is the car and the parts you get with the roller:

Before going any further and getting started with stripping down the car I wanted to check the weight of the car. Not that I am fanatic about the final weight but with that said I still wanted to keep an eye on it making sure that no fancy upgrades were to be added if the had too much of an impact on weight. Here the weight before stripping down the car (13.6kg = 30 pounds):

So now it was time to start getting rid of things that were not needed in the brushless conversion. First thing to go was the fuel tank:

I had also decided to use the ESC and Brushless motor for breaking so next up was removing the standard breaks:

With these parts removed the Losi 5ive-T had already shed 500 grams (1.1 pound) and now weighed in at 13.1kg (28.9 pounds):

All in all this took 15 minutes and the car was now ready to start installing the first parts. Stay tuned for part two where we mount the motor and ESC and please do comment below if you have questions or things you would like to know more about.
