Assembling the loco

• Locate the wheels, axles, axle boxes and O rings
• Drive pulleys have already been prealigned on the axles - note they are correctly in slightly different places on the axles

• The jig is to help set the gauge at 32mm or 45mm
• Put the wheel on the jig as shown
• Use a small hammer to tap the axle into the wheel
• Repeat for all 4 wheels
• Check the back wheel back to back distance with a ruler - it should be 28mm for 32mm gauge or 40mm for 45mm gauge

• Gently push the motor into the hole in the chassis - do this just once so as not to strain the connection to the wire

• Push the motor holder right through the hole on the underside of the chassis to secure the motor - it is a tight fit and you will need to wiggle it
• Put an O ring onto each axle
• Put the axles into the bearings in the axle boxes with the pulleys on the side away from the motor block as shown - it does not matter which axle is which
• Push the axle boxes into the chassis firmly - these are a deliberately tight fit and should not need gluing so they can be removed for maintenance later if needed
• Check the axles rotate freely
• Carefully stretch the O ring on the axle with the pulley closer to the middle onto the motor pulley nearer to the motor - you may find a pair of tweezers helpful but be careful not to damage the O ring
• Stretch the O ring over the pulley on the motor
• Repeat the process for the other O ring and axle

• Glue the buffers to the chassis - note the orientation with the larger part above the chassis floor
• Make sure the buffers are square - you can check by putting the body between them

• Glue the bonnet ring around the holes on the front of the bonnet

• Locate the LED, light surround and 12mm clear round lens
• Push the LED into the surround - its a 5mm LED so use a 5mm drill bit in your fingers if necessary - remove the LED
• Peel the protective film from both sides of the lens
• Fit the lens to the light holder - you can use Glue 'n' Glaze but it is a tight fit and should not need this

• Feed the wires through the hole in the bonnet and push the light surround in place

• Place the body on the chassis feeding the motor wires through the floor
• Push the bolts through the floor and into the body
• Note the orientation of the switch and charge socket holder - the charge socket should be against the same side as the Mini B
• Gently bend the wires on the bottom of the switch and charge socket inwards
• Push the nuts fully into the holes on the top of the holder
• Screw the bolts up through the floor into the nuts

• Do not connect the battery yet
• Push the on/off switch towards the charge socket so that it is off
• Connect the white power plug into the Mini B white socket - it is keyed and should only go one way with the red wire on the outer side
• Connect the 2 yellow and orange wires from the motor to the 2 pins on the edge of the blue board with the orange wire plugged onto the outer pin further from the white socket so that loco goes in the correct direction - if you get this wrong you can always swap the wires round later
• Connect the (optional) black LED wire to the pin marked F LED - on the edge of the green board
• Connect the (optional) white LED wire to the pin marked F LED + of the green board adjacent to the black wire
• The onboard resistor at the other end green board has been set to 100 ohms - you can change it to 50 ohms if you want a brighter light but NOT to 0 ohms as that will blow the LED

• Push the Mini B into the slot inside the body
• Put 4 AA NiMH batteries in the holder and connect this
• The charge socket is a standard 2.1mm DC power socket with positive centre pin
• The batteries can be charged directly using a smart charger suitable for NiMH battery packs - contact Strikalite if you do not already have one and ask for a 2.1mm DC power plug with positive centre pin
• If you don't have and don't want a smart charger then just remove the batteries from the battery holder and charge them individually in an AA charger

• Mini B setup guide
• Wi-Fi connection and controller operation guide

• Turn the switch on - push it away from the charge socket
• The blue LED on the Mini B board and the (optional) clear LED should do a brief flash
• Connect your smartphone to the Mini B as described in the Mini B setup guide
• Run the controller from your screen
• If forward and reverse directions are the wrong way round swap the yellow and orange motor wires
• The LED should go on if you tap Lights and the direction is Forward - note it is directional and will go off in Reverse
• You can change the name on the screen (for example to Motor Rail) and password if you wish as described in the Wi-Fi connection and controller operation guide
• The Mini B has already had it's 'Shutdown on low battery' preset to off since you are not using a lipo
• Once you are happy everything is working correctly, turn the switch off
• Always remember to switch the power off when you have finished running so the batteries do not fully drain

• Cut the 2 strips of weights into individual pieces
• DO NOT remove the blue backing from them
• Push the 10g weights into the larger space and 5 g weights into the smaller space in the seat support

• Glue the seat base onto the seat support
• Glue the floor box to the back of the body and floor - one only one side is flat and this should go against the body

• Glue the small oval cover to the side of the body as shown

• Glue the throttle to the back of the body, noting the orientation

• Glue the seat on the seat holder with the seat front aligned with the edge of the holder

• Glue the brake lever against the back buffer aligned with the whole in the floor

• Glue the rear bar to the buffer - note the orientation so that the flat part is attached to the buffer
• Cut the rivet coupling pin to length for the buffer hole

• Drivers Ron and Violet have been specially designed to fit and are available in 1 inch scale from the Clavey Models eBay store
• Power it up and enjoy
• Always remember to switch the power off when you have finished running so the batteries do not fully drain
