  1. Thanks I will try that out, time to check all my wheel types
  2. Changing standards is not an option, apart from my ancient hands not being up to the job I have 47 code 100 points already installed. so what is the recommended solution
  3. For me the size of battery is dependent on how much the loco works in the operating session. For example my sessions last no more than 3 hours and a large pacific loco pulling a 12 coach train at speed consumes about 500mA . While idling in the fiddle yard it consumes 20mA. Half an hours running (over 50 circuits of the layout) consumes 250mAh and two and a half hours idling consumes 50mAh. So a 300mAh battery is needed. In my large locos I use a 2S battery so theoretically a pair of 160mAh will do the job. I use 190mAh or 250mAh. Actually a pair of 320mAh is just fine as the locos don't run for anywhere near half an hour.
  4. Wheels falling into the crossing Vee gap is what irritates me. all my latest Hornby, Bachmann and Dapol wagons do it. The points are all Peco code 100 so it must be the points that is the problem.
  5. From the pololu site they are discontinuing that series of regulators but you might find some online
  6. Yes, 1 inch = 25.4mm. As I understand it this was adopted to lock the US system into the international metric one. It might not work the other way round though. Converting 25mm to US gives you 0.9842519" and my calculator ran out of digits. The NASA incident was probably caused by quality control issues, someone should have checked with a laser that those components were within tolerance. The USA converting to metric would cost a LOT of dollars for little advantage. edit - I am of the generation that is comfortable with both, younger colleagues would look confused when I was marking out 7" x 50mm
  7. LOL, apparently they still use feet and inches over there. The metric dimensions are on the product page. I seem to remember that NASA lost a very expensive planetary probe because a fuel valve stuck closed. Nasa use metric and the contractor used imperial, doh!, there is no exact conversion
  8. The basis difference with o scale is the locomotives might need more power and or a higher voltage. The radio receiver (Rx) has to have a large enough output in amps. A typical oo scale Rx would be 1.3amp at up to 13V. Other receivers can go up to 6 amp at 18V. The advantage of O scale is you should have plenty of room for the electronics and batteries.
  9. Sometimes you do need a switch because swapping the battery out to charge it is just too difficult. It should be OK with a tender loco as the battery is in the tender and you modify it so the tender top is easy to remove. I think the Deltang Rx use about 15mA when not supplying power to the motor or 20mA with a Pololu regulator added.
  10. Ah, makes sense now. the Rx63 LVC function should handle any low battery issues It will be interesting to see how the conversion turns out. I have a Hornby Railroad Jinty converted but the mechanism is a bit crude.
  11. Ares 50mAh LiPo 40mAh LiPo Cell with BMS and Wires Interesting, different capacity batteries . I have never seen this combination I presume you are going to use the 2 batteries in series giving 8.4V when fully charged and 6V when depleted. Will the smaller battery with the BMS protection circuit shut down first? How are you going to charge the batteries? What loco are you going to fit this in? Maybe a good idea put it all in a trailing open wagon for testing before butchering the loco.
  12. I have no problems with TV suppression issues. I think the reason it was a problem was you had a very long aerial, the rails, to broadcast the errant signals. With radio control you only have the leads from the receiver to the motor. I remove the capacitors. Actually my RC locos can cause interference on my transistor radio AM/FM but only if the radio is less than 18 inches from the loco. Modern TV's are almost exclusively digital and people tell me this is much more resilient than the old analogue signal. Also, apparently anti suppression circuitry is not fitted in some other countries. Prepare for a long contradictory 'discussion' !
  13. Yes, however model railway locomotives require much lower discharge rates than hobby Lipo batteries are specified for. model plane and drone users need very large discharge rates because they need LOTS of power. For example one of my little hyperion single cell lipo batteries has 160mAh capacity and is rated at 25C. This means it can provide 160mA of current for 1 hour or 4000mA for 2.4 minutes, theoretically, but you would need thick wires! also with charging airplane users want to charge their batteries quickly while us sedate users don't mind using a slower charging rate. The same rules apply though, never leave a battery charging unattended and use good quality chargers
  14. The basic differences between Deltang and Protocab is Deltang has a much more extensive range of receiver and battery options. a more capable range of Transmitter (controller) options and it is a lot cheaper!. To offset this you have to do some of your own wiring, think of having to hard wire a DCC decoder. I await with interest the Protocab new product reviews. As far as the OP's question goes, you can get a Deltang starter system for about £112. The Protocab starter pack is £240. Deltang is British too. A caveat about the Deltang system is the announcement a few days ago that some of the components of their receiver boards and transmitters will no longer be available which means they have stocks to keep production going into 2021. This means that David Theunissen has about a year to redesign the boards around substitute components. See the news section on the Deltang site. I looked a Protocab but for me the killer problem was, although you could have 9 locos assigned to the controller, only one could be moving at the same time.. I have 3 continuous run circuits on my layout plus goods yards and a loco shed, so for my one man operation I can have 3 trains running on the through lines and one loco shunting etc. A Deltang Tx22 transmitter can have 12 locos running independently at the same time. Does the new Protocab controller fix this? edit - Deltang also has products for other radio control applications such as boats and cars etc (see the radio control vehicle topics here on RMWEB, they mostly use Deltang stuff. this is because it is based on model aircraft radio technology. I understand that David Theunissen was one of the leading proponents of electric power for model aircraft.
  15. Ok, if you think you will use DC then it might be better to spend the £112 on other stuff. None of my Lima diesels are dual motored, they must be conversions, so I have no experience of adding RC to such models.
