Went to a model railroad show Saturday and could not resisit a Bachmann 0n30 Two Truck T Boiler Shay I found at a great price.  It looked like a simple RC conversion candidate.  After looking at the parts diagram and removing the fuel bunker I was convinced everything would fit well.  First I removed the Bachmann circuit board and cut off the three standoffs that supported it.  After removing the board all that remained were the two motor leads and the two headlight leads.  I unsoldered the leads to the truck pickups and pulled those wires out with the circuit board.  I made up a two cell Lipo battery pack with a battery protection circuit and installed it under the fuel bunker.  I made up a mount for the DelTang receiver and Pololu 9 volt regulator from card stock attaching the components and mount with RC servo tape.  This ensured everything was insulated.  The switch is temporary.  I have not decided on whether to use a switch or a magnetic reed switch yet.  I installed a charge jack under the frame at the rear.  Once painted black it will not be very visible and is easily accessed.  I have also not connected the LED headlight yet.  I will have to add a resistor.  It will be wired to be on anytime the power is turned on as a reminder to turn off engine when not in use.   I am pleased with the result as the Shay runs great and realistically slow with this set up.
In the right side picture you can see the battery pack wired to the protection circuit board.  The two motor leads are visible and attached to the DelTang receiver.  The two thin leads at rear are the headlight leads.  The two heavier wires coming up from frame are the charge jack leads.

Bob,

Very nice work!  :2t:


I've got a Shay also that I plan on converting to BPRC.

Good job! The installation doesn't look difficult, maybe your work will inspire more modelers to try BPRC. :)

Looks great. If you ever get the chance or desire, I'd love to see a little video of it running.

You mentioned r/c Shays?



From many years ago, a "converted" Bachmann On30 Shay with 7.4 volt battery and an r/c car board (now looked down at)...
but she's been running for maybe 15 years and still does switching when needed. Woodie

Woodie,  Is this the same engine as #5 - Lizzy?  Your Shays are the inspiration for me buying this Bachmann unit.  Not certain what I will be doing with it but probably convert to 1/35n2.
Model car type conversions are great.  Considering when you began proving the concept, it was the only option.  Not sure I would like to mess with the old 72 or 75mhz though as the antennas for both the transmitter and receiver were a bit of a pain.  With all the newer 2.4ghz and smaller sizes available it is nowhere near the challenge you faced "back when".
