Motorised 9392 Quadbike

I had a sudden urge last night to make a fast RC vehicle with suspension. So I decided to motorise the 9392 Quadbike set.
Motorised 9392 Quadbike

It is driven by an XL motor geared up 1.66667:1. This results in a reasonable amount of torque for it's size, and it is very quick.

The steering is done via a worm gear and 24 tooth gear assembly, placed above the suspension struts. It is a reliable solution and fits rather well, except for the M Motor poking out of the front.

I have retained all the original features (working handlebars, suspension and 1 cylinder fake engine).
I changed all the soft springs for hard springs to handle the extra weight of the Power Functions components.
I am happy with the result, even though it is very ugly, it is incredibly fun to play with.

Tank Destroyer

I am pleased to present my latest MOC; Tank Destroyer.

Tank Destroyer

I was originally planning to build the British A39 Tortoise Tank, however, due to limited pieces I decided to go for a generic Tank Destroyer design.

Tank Destroyers are tanks without turrets and with bigger guns, designed for one sole purpose, to destroy tanks. Some examples are tanks such as the German Jagdpanther or the Soviet ISU-152.



My tank destroyer's closest resemblance that I know of is the American T18.



Anyway enough history, onto the model.
It uses two M Motors geared down 3:1, the result is fairly reliable and it has only just enough torque, but does the job for the space available.

Tank Destroyer Drivetrain

I have used bogie suspension, which works faultlessly, except for the fact the suspension movement is very small.

And finally the exterior of the model, which, I admit, was a bit rushed, however, I am still pleased with the outcome.

The performance of the model is pretty good, it isn't fast but then it's not supposed to be, it's a tank. It can do some "off roading" on terrain like snow, grass, soil and Lego. The gears within the drivetrain do slip quite often awful creating the dreaded "grinding noise" which can be annoying at times. Finally a video, (yes it did snow in the UK in March...)
