Good job! well done!

It needs a big heavy trailer to make it "chuff" now!

Brilliant work!
Smooth running!

most steam engines run single pinned on the road anyway so you should be fine until you do heavy haulage or steep grades

There is rock available in the axle,  so no problem.

 

I plan on putting chains on somehow.....!

I found a motor yesterday that would have allowed me to operate the chain steering drum - but too late! This works, and I'll quit whilst I'm ahead. If I ever do it again, I shall have a suitable motor in stock.  

 

To clarify by rock I meant mimicking the slack of chains as the wheels hit obstacles not the pivoting beam.

Sounds good! So a road roller next?  

Looking good!
I like the steering mechanism maybe add a little slack in the system so the axle rocks as it goes over bumps like in the first video for realistic movement?
I guess chain steering would have been a nightmare to package?

Looking good Giles, you going to use a steering servo to turn the bar that controls the steering chains to mimic the full scale ones?
You may be able to get square profile O rings like the ones used for pneumatic cylinders to use as scale vulcanised tyres ?

Ah..... you can find the Berkeley's on an Ebay (international) search. Theyre not cheap, but they are very nice. I got one as I had three - although only one ever got on the road.... I ran it for a while both in the Valleys and in London when I was a student. Great fun.....

Yes they are brilliant fun! It used to be my job to lift the back end around to get it square to the kerb when dad parked! 

Nice work as usual Giles.
As well as being a huge Scammell enthusiast I also have an interest in vehicles designed by Laurie Bond (blame my dads collection) which leads to me wondering where you got the Berkeley T60 model from?

Loving that little Landy! Is there a build thread for it?

Loving the Imp!
We have a few of them lol

ERF also made a model nicknamed 'Sabrina'

On the Rx45-5, One positive is an input from the battery - the one one the bottom right - also labeled 'lipo', and the other one on the left is a positive 'out-put', used in conjunction with the F1 (and F2, presumably) for a single direction motor. (Instead of the H1 terminals)

 

I must say that I'm such a coward as far as soldering onto these teeny receivers, that I pay the two quiz extra for the wired versions to save me the trouble!!

Hi Giles, i only discovered the pre-wired ones after buying mine, going to have to do it the hard way.

Tim was right Dave was VERY helpful with almost instant reply, got an action plan in place now, just need to measure up for a tiny LiPo

Thanks Tim,

I have the RX45-5 and one that confuses me is the two 3-6v inputs?

Frankly, things have moved on so much in the last few years, and got so much cheaper, that I shouldn't use your old RC gear, as it will actually make life more difficult for you, and make the end result less effective. (I've been through that, and also have a pile of perfectly good, but 'unusable' transmitters, receivers etc. that I now have no viable use for, and am never likely to.....)

 

The DelTang 2 GHz 2DSM system is the one to use - it is cheap (under £30 for a combined 4 channel receiver/speed controller) that is only 10mm square, and the appropriate Tx can be bought on eBay for about £15 usually (check on the DelTang website for details.

The servos are the standard micro servos at about 2.7grammes or such, and the motor gear boxes are the micro-gear motors for places like Technobots (and EBay). I use the 6v 100:1 ratio.

thanks GIles,

I think i remember you wanting to try 260:1 combined motor, gearbox and axle, did you get round to trying that?

Also did you try the 1.7gm 'worlds tiniest servo' i think you also found?

I used to be into model railways and remote control models but these days i mainly work in 1:1 however im finishing my degree so im looking into something that i can tinker with on the kitchen table at Uni 

Im looking at a Scammell Highwayman to make as RC 00 Gauge so should be fun

Brilliant work folks! Keep it up!

EDIT:
Giles, after all the conversions youve done and the knowledge youve acquired is there a RC conversion set up you can recommend?

Im looking at RC converting Corgi 1:50 and 00 gauge model trucks and possibly build a plastic kit as RC.

I have some 2ch RC gear from my childhood so should have a Tx to work just want to know what motor, gearbox, servo, speed controller, receiver etc you would recommend to save me having to repeat your learning curve.
