wasdavetheroad Posted September 12, 2020 Share Posted September 12, 2020 Neat even at over $50 a pop. How about posting the links on the radio control forum, once they get their hands on them they wont be looking like minis for much longer 1 Link to post Share on other sites More sharing options...
PenrithBeacon Posted September 12, 2020 Share Posted September 12, 2020 What components did you use for such a small BPRC model? I'm surprised it's possible. Cheers 1 Link to post Share on other sites More sharing options...

Cheers There is a chap who scratch builds his own 009 locomotives and he uses motors from mobile phone vibrators, these motors are tiny, no more than a centimetre long and 3 mm diameter. They are proper motors as well not the 'make and break' type. Link to post Share on other sites More sharing options...

A pity. 1 Link to post Share on other sites More sharing options...
Giles Posted September 13, 2020 Share Posted September 13, 2020 For radio control locos, I use gearmotors of various sorts, which give me the output speed of the desired wheel rpm. I then use bevel gears for the final drive. You can get such a large variety of gearmotors that there is usually a solution. 1 Link to post Share on other sites More sharing options...
PenrithBeacon Posted September 13, 2020 Share Posted September 13, 2020 I was thinking of cars in the context of 4mm railways. The idea of an BPRC Mini is very attractive, but it is attractive only if its speed can be realistically controlled which, as you say, means an output RPM of around 100. When I've finished the Jinty I'm currently working on I've every intention of doing a road vehicle, a Bedford CA van. I already have the motor for it, one of the planetary gearbox motors shown in your earlier post. Cheers 1 Link to post Share on other sites More sharing options...

Giles Posted September 13, 2020 Share Posted September 13, 2020 Do you mean one with the bevel gears, David? 1 Link to post Share on other sites More sharing options...
PenrithBeacon Posted September 13, 2020 Share Posted September 13, 2020 Not sure if we're not getting at cross-purposes. What I meant was a motor that has an output of around 100rpm so it can be used to directly drive an axle using bevel gears. The motor can be geared to get 100rpm or it can be in it's 'native' state. 3 to 6 volt would be ideal. I've looked on eBay and can't find anything, 9k-20k rpm seems to be the normal design range which I can understand for their use as vibrator motors. Having said that, such a small motor would be great for 4mm private cars . The K20 is good for commercial vehicles, but I speak theoretically as I haven't yet got round to doing the business yet!

Giles Posted September 13, 2020 Share Posted September 13, 2020 Ah right - yes, the 6mm gearmotors I linked to above are 100rpm output at 3.7v, so they work quite well. 2 1 Link to post Share on other sites More sharing options...
Pikey Posted September 29, 2020 Share Posted September 29, 2020 (edited) I've not long received mine, and I have to say its really good - quite a lot better than the Carson VW offering, and I think a lot of that is down to the controller - these have a small trigger style controller much like the type you'd expect for a bigger RC car, with both trim and range control for steering and throttle channels, plus a button for a third channel (which is spare on the mini) They cost around the same as the Carson VWs, once you've paid for shipping and VAT / customs charges, and they both look better (being the right scale) and drive better too.
