I was asked to do a video for last weekend's 'virtual exhibition ' so I did another rc conversion especially for it. This shows just about the whole process in one go, for those who are interested. I don't think I'll post any more of these, unless there is something very specific of interest - as it's just repetition if I do..

And lastly, one of my axles fitted to a 4mm Series 2 Land rover.

I'm aware of someone in Germany making ridiculously small vehicles - and a chapnwith the handle 'Otherplanet' has converted a 4mm Scarab to RC, son in theory it's possible. The receiver can't be shrunk, one would do away with the servo, and use an Actuator instead, which is much smaller and less powerful. A very small battery...... finding a small enough motor gearbox combination would be a challenge......

Have you thought about using the motor which makes mobile phones vibrate ? Steve one of our club members has used one to power a 4mm WW1 petrol simplex, I don't know what gears he used.

What really 'sells' that picture to me is the undulating track. Well, and everything else......:thumbs:

Quite amazing! I've been into RC models for years but never seen anything quite this small!

Bless you all - it was a hit of a tight fit - but of course there are some amazing people who managed to do even smaller stuff!
The challenge I took on was the front axle, as I have a now tried and tested technique for axles which will work for 4mm lorries and anything larger, but not for something as small and narrow as a Land rover, so it was back to the drawing board. It proved relatively straightforward, and 'car's axles are viable. I have even looked at axles this size incorporating rack and quadrant steering (useful for when the servo has to be set back)

Thank you Mike!

I've now got the drive sorted, and fitted one of the diffs I made some time ago, as this will need to be agile with its short wheelbase etc.. I was planning on using a different motor and gear combo, but I couldn't fit the motor in transversely between the chassis. This is simpler in many ways, but takes up valuable battery space. The smaller motor for the last tilt is on the centre-line.
