[MOD] 42005 - Monster Truck - 2.4G RC conversion

[microwavefood]

Hello all!

I think 42005 is a good kit to convert into RC crawler. After a few weeks of work, here is the RC Monster Truck.

As I don't like the IR control idea, so I take some RC electronic:

1. RC 2.4g receiver

2. ESC (Electronic Speed Controller)

3. 9g servo with custom servo mount

With some soldering and drilling with custom parts, This baby now controlled by 2.4g RC transmitter.

The car can use both Lego power function battery box or 2S Lipo.

Powered by a 2S 900mah lipo, the running time is over half an hour with the L-motor.

Currently, the car is rear wheel drive, I have tried some simple steering design but as the front part is not horizontal, the front wheel is forced outward.

Anyone have ideas on converting this car to 4wd?

In before anyone else -> video?

nice conversion but I don't really like the use of non lego motors for it, it kinda takes the fun out of fitting massive lego motors into the small chassis. I have done a conversion of the kit but it was only front wheel drive and could have been all wheel drive, if i had another M motor at the time.

sorry for bad video quality, it's a older video.

Interesting solution using both PF and 3rd party servo.

There's a topic with AWD and steering done completely with LEGO.

Exactly.

It's not really fun when all the motors are not compactible so easily with lego bricks

After all, there is still the micromotor, 70823

The reason behind choosing a RC 2.4g TX/RX system over the Lego PF IR system is the natural of the model.

While Lego PF IR system is good for controlling multiple actions, the IR system has its limitation such as range and require line of sight. It is great for models with many different actions such as 8043 or 42009, but most likely you are controlling the model in a rather short range.

For this monster truck, I see the potential of this model that it will be great to be played in the field. The RC 2.4g Transmitter provide much larger range, for example, the Transmitter I am using have a range of 1km, and radio signal require no line of sight, which is more stable in controlling distance model.

Fitting massive lego motors into the small chassis is fun, but fitting RC parts into Lego model is also challenging. So why make the boundary to limited the possibility of this great model?

I will bring it out to the field and take some video later on.
