Pushing on a spray can valve with your index finger can get tiring quickly. A spray gun handle with built-in trigger makes painting a RC body much more enjoyable.

In 2014 Tamiya changed their kit ESC to the TBLE-02S model. The speed controller features a low-voltage cut-off function, but it is set to 4.9V -- much too low for LiPo batteries that most RC enthusiasts use nowadays.
However, by adding a single resistor we can modify the cut-off voltage to a LiPo-safe 6.0V or 6.3V.

A few weeks back we were discussing with fellow RC enthusiasts how difficult it is to paint the eyes on the plastic driver figures, like the Wild Willy or the Rally Cockpit. Turns out help is at hand:

Companies like LRP make rounded LiPo batteries which fit into the round cavity found in older Tamiya bathtub chassis like the TA01, TA02, TA03, CC01, DF01 or FF01. However, compared to NiMH stick packs the LiPo cases are about 5 mm longer. This means that the battery is sticking out too much and the battery holder that comes with the car no longer fits.
We designed a 3D printable holder that solves that issue. For good measure we included a case for the popular 1-8S LiPo monitor -- often those old cars run speed controllers without LiPo cut-off.

The LANE Boys recently acquired a 3D printer. Beside printing spare parts and accessories, why not print a body shell?
A few years ago we were amused by the motorized furniture creations of Edd China. So we decided to build this:

Tamiya has a good range of colours for polycarbonate named PS. But sometimes a RC project demands a specific tone that is not available. What to do?
Using our favourite search engine revealed that it is possible to spray other types of paint over PS-55 Flat Clear. We gave it a try and the results was excellent.

After long consideration, the LANE Boys finally got a 3D printer. One of the applications we had in mind is printing custom light buckets for RC cars. The first results are very promising.

Recently we tried to sell a newly built Tamiya TT02 Lexus RC F Eneos Sustina. That did not go as well as planned; it took quite some time and we had to sell the car in pieces.
However, the photos I posted along with the ad led to someone contacting me, asking whether I'd be interested in painting a body shell and installing lights. My first client <smile>.

If you are looking for a low-cost standard size servo on Aliexpress, eBay, Banggood and such, you will stumble over the SG5010 servo. Four of these servos can be bought for USD 17.40 including shipping, which makes it an astonishing low USD 4.35 per servo. And that includes worldwide shipping!
But are those servos any good? Lets find out...
We are cheap. And therefore we like stuff that delivers a lot of value for little money. One of those items is the Team Powers Cup Racer TP-540B-94F "black can" motor.

Its always fun learning something new. Ever since we got a 2.4 GHz RC system a few years ago, I wanted to understand how these things actually work. How do they send data over the air? What components are used?
Well, in the last months we finally got around digging into it. And it turned out that it is a rather simple affair. So we built our own RC receivers.

In recent years LEDs are appearing on the market that contain a controller chip. Currently the WS2812B is highly popular. It is a RGB LED that contains a simple chip inside. The LED is controlled through a single pin using a serial shift-register-like protocol. Multiple LEDs can be chained together; like a Christmas light.

The WS2812B is an RGB LED with a built-in shift register like controller. It has 4 pins: GND, Vdd, Data-in and Data-out. With only three wires going from LED to LED, one can control each LEDs color and brigtness individually.
Using such LEDs makes wiring up a vehicle very easy: one only needs to run 3 wires from one LED to the next.

The PL9823 is of particular interest to us as they are in the traditional 5mm dome type LED package and therefore can be installed easily in the light buckets that come with many 1/10 scale RC car body shells.
From a software point of view the PL9823 is compatible with the widely popular WS2812B, with the exception that the data format of the PL9823 is red-green-blue while the WS2812B requires green-red-blue.
The brightness of the PL9823 and the WS2812B seems comparable. However, a downside of the PL9823 is that even if it is not lighting up, it already consumes 7-8mA of current. In comparison, a WS2812B LED consumes less than 1mA when it is off. The 7-8mA is still acceptable for use in an RC car and won't hurt your run time much, but one still needs to take this into account when desiging a system around those LEDs.
The chart below shows the current used by the LEDs when set to white with different brightness values from 0 to 255 on the red, green and blue channels. The PL9823 current usage is ~8mA higher than the WS2812B at every level.

Most servos and speed controllers come with a wire that is too long for the average RC car. The usual way to deal with this is to either make a spiral by tightly wrapping the wire around a pencil, or by carefully bundling the wire up and securing it with a zip-tie.
A better way, albeit requiring more effort, is to shorten the servo wire to the exact length needed. The unused length of wire is just ballast, and also restricts current flow.
This post shows you how to shorten servo wires.

One type of vehicle that was still missing from our RC fleet was a truck. Tamiya has very nice models; we liked the Globe Liner a lot, but the Mercedes delivery truck would have made more sense for us.
One day we were looking at the offers on eBay and found an old kit from the German manufacturer Robbe. A week later the auction ended and we had the pleasure to win it. Another two weeks went by until we could hold our latest wheeled toy in our hands:

A few weeks ago we bought a cheap second hand TT-01 because LANE Boys Snr. wanted to have a 10th scale touring car for relaxing in the local park. Along with the TT-01 came another box: A semi-vintage FF02 Alfa Romeo 156. The body shell had been used quite a bit and was heavily damaged. The chassis was incomplete, but in excellent condition. The front uprights were stripped where the king pin screws go in; turn buckles, servo mounts and a drive shaft were missing, but the rest of the vehicle looked like the car was never run before.
So we've set out to rebuild the car to its former glory.

Want to control you 1/10 scale winch from your 3-channel RC system? Below you can find instructions to build the necessary controller!
First, check out the video to see how to operate the winch:
It has been a while since be blogged about our Light controller. In the meantime we have equipped more than ten cars with our custom electronics.
In this post we describe the changes we did along the way to the electronics and the firmware.
