I think this is about as good as a G95 motor/gearbox from Sol Expert will run, as the slow speed control isnt really there, but the top speed is about right if you want to drive along a road. Have you tried putting either one or two pairs of back-to-back diodes in the motor feed to drop the motor voltage ? That might give a bit better low speed control. I used that on my 2mm scale bus. For the currents involved, the diodes can be very small. I agree another ratio would be ideal, but with off-the-shelf motor gear-heads, its not an easy option. 1 Link to post Share on other sites More sharing options...

Pikey Posted September 5, 2020 Author Share Posted September 5, 2020 Haven't got a lot to show here for the moment, but I have picked up a few commissions - to do three near identical loaders (so I'm going to make a fourth one for myself at the same time) and a crane lorry But my order from Germany has been delayed - on the UK side (obviously) so I haven't done much other than cut holes for the motors so far. Hopefully my motors and servos will arrive soon and I can show some progress. 1 3 Link to post Share on other sites More sharing options...
Pikey Posted September 16, 2020 Author Share Posted September 16, 2020 So in actual fact the parcel had the wrong address on it - so it made it all the way from Germany to within about 100 yards of my house, before being returned back to Germany! 4 Link to post Share on other sites More sharing options...
Pikey Posted September 21, 2020 Author Share Posted September 21, 2020 The parcel finally arrived at the weekend Progress pictures on loader #1, I'm about 4 or 5 hours in so far (including thinking time - the other three vehicles will be much faster as I know what I'm doing now): Make hole for motor/gearbox, also drill holes for micro switch and charging socket I think the servo is going to sit approximately here, I want to get it as low down as I can because I want to retain the driver figure if possible: Make space for battery and receiver in the engine bay. I'm actually going to use a smaller battery because the servo location will eat ever so slightly into the space at the front of this piece: Take apart the arm/bucket - harder than you'd think, because its fitted together with steel rivets that need to be drilled/Dremelled out very carefully to avoid damaging the arm. Enlarge the holes to take 2mm diameter brass tube bearings (the ones on the end broke as the metal is too thin, but superglue should be strong enough for this to hold together in operation (I hope), and make space for the central cogs: 3 4 Link to post Share on other sites More sharing options...

Giles Posted November 12, 2020 Share Posted November 12, 2020 (edited) To be clear, it looks like Dave's packing in the Rx 6x series - but continuing the lower voltage receivers. I'm fortunate in so far as I use low voltage motors in my loco as well, so the Rx41s do me very nicely. Maybe the work-around is to consider re-motoring the chassis with a 3 or 5v motor? Assuming you need the higher speeds, That is. Conversion if road vehicles will be unaffected by this. Edited November 12, 2020 by Giles 1 1 Link to post Share on other sites More sharing options...
otherplanet Posted November 13, 2020 Share Posted November 13, 2020 But interestingly Micron appear to be taking up the reins, if not directly. See here http://www.micronradiocontrol.co.uk/rc_rail_status.html Unfortunately the Rx47 is at the end of the priority list. But as Giles says, the 41, 43 and 45 seem to be continuing. So hopefully the micron stock status is just a temporary blip 3 Link to post Share on other sites More sharing options...
Giles Posted November 14, 2020 Share Posted November 14, 2020 I just want to say that I've been buying small radio gear from Micron for ten years now, and Andy Rutter has been brilliant and helpful throughout. No other connection! 1 1 Link to post Share on other sites More sharing options...
Pikey Posted November 19, 2020 Author Share Posted November 19, 2020 Realised I havent updated this thread for ages! I now have the first loader working and it will be off to its new owner very soon: I had to use the next size up servo, 2.2g, as the smallest one that I use for everything else just wasnt powerful enough to move the steering. So any hope of retaining the driver figure / cab detail went out of the window - the cab is now full of servo and wires, in fact the wires are bursting out of the window a little bit as well. I crammed it as hard as I dared, but there just isnt quite enough room in the engine compartment! The next three, including the one with the logging attachment, are about 50% complete and I'm going to add lighting effects to the last one which is going to become the new star on my layout whenever we are able to do exhibitions again :-) 2 5 Link to post Share on other sites More sharing options...
Giles Posted November 19, 2020 Share Posted November 19, 2020 Looking good - on a vehicle like that, have you thought about using a linear actuator to steer, rather than a servo - or isn't there sufficient room? 1 Link to post Share on other sites More sharing options...
Pikey Posted December 17, 2020 Author Share Posted December 17, 2020 I think the ones I've seen on Youtube from Germany are controlled like that, but I cant for the life of me see how there's room for 3 of them - one to control the steering and another two to control the arm and bucket! The next pair of loader and logger are finished and in the hands of their delighted new owner You might just be able to see I did manage to cram the driver figure back in the cockpit, although he's a lot further forward than he should be. The logger is loads of fun I seemed to be pretty rubbish at driving it, hopefully new owner Bob will get the hang of it. So I can now FINALLY work on my own loader, and I feel like putting some extra effort into the lights - they have work lights at the front and rear, plus extra lights at the top of the cab and possibly tail lights and reversing lights as well, need to do some research. I've also ordered a 'rotating beacon' - which is actually 3 LEDs inside which flash in turn to simulate a single light going round and round 5 Link to post Share on other sites More sharing options...
Pikey Posted February 12, 2021 Author Share Posted February 12, 2021 Still nothing to report, mainly due to the fact that my garage is the same temperature as outside (due to zero insulation and an inadequate heater), so when its as cold as it has been recently, I just dont go in there. I've got another crane lorry that I'm working on at the moment, which I'll post pictures of when I've made some decent progress 1 2 Link to post Share on other sites More sharing options...

Pikey Posted March 12, 2021 Author Share Posted March 12, 2021 My second HIAB crane lorry is driving and steering, with emergency beacons, test video below. This is the same chassis that my yellow one is based on, a Cararama Mercedes box lorry with the back chopped off. Pleasingly, the inside of the box is detailed with a slatted base which looks great as a flatbed by simply painting it brown, and it covers a slim 350mAh battery which I think is a better way of doing it than disguising a battery as a tarped load on the bed. The last part to do is the crane itself, you can see the white blue and green pairs of wires sticking out ready for connection to the three motors. 2 3 Link to post Share on other sites More sharing options...

Pikey Posted May 7, 2021 Author Share Posted May 7, 2021 Still not got around to the actual crane - its all prepared, just need to find the time to do it. In the meantime, I fitted a 'rotating' beacon to the Green Goddess I did earlier: 7 3 Link to post Share on other sites More sharing options...

Pikey Posted July 12, 2021 Author Share Posted July 12, 2021 Over the last few weeks I've been doing some work on the Faller Car System I've got on my garage layout at home. I now have 5 vehicles - three standard Faller vehicles plus two I've modified myself - and the latest one is a Scania timber lorry which I've chopped all the timber stuff off and made it into a simple flatbed. With a home-made route choice and stop section (servo pulling a bit of fishing line to bend the wire, and another servo-operated magnet that operates the reed switch on the underside of the vehicles) I can now bring in a flatbed truck and load it with my telehandler. It stops and starts abruptly, but its just a bit of fun 6 Link to post Share on other sites More sharing options...

otherplanet Posted July 12, 2021 Share Posted July 12, 2021 Very nice. I have often thought that a combination of faller and radio control ought to allow larger numbers of vehicles, whilst maintaining the interesting bit. It also occured to me that a hybrid system using a Deltang receiver with the buffer stop function enabled could help to control the abrupt acceleration. Potentially you could use an extra servo channel to swap between servo and wire controlled steering to allow it to break free. 2 Link to post Share on other sites More sharing options...
Pikey Posted October 3, 2022 Author Share Posted October 3, 2022 I've been absent from this forum ever since it completely changed and now half the page is covered in adverts, with additional adverts and videos popping up all over the place. What a shame :( Anyway, I have a facebook page, so if you'd like to keep up to date with what I'm doing just search for J P Models. I'll be exhibiting at the Cheltenham model railway exhibition at the end of October too :) I'm doing a couple of tractors just now, one with a bulldozer blade and one with a front loader, and I'll be tackling a reach stacker and a wheeled 360 excavator in the near future. 2 2 1 Link to post Share on other sites More sharing options...
