Heljan OO Class 53 Diesel Falcon

Heljan OO Class 53 Diesel Falcon

Kit: MS450R; Howler10; MGOLANG

We haven't seen one of these models for a while, but always good to revisit the older models with new kit. Heljan's OO Falcone has an 8pin DCC socket, and enough space for a decent level of kit without any great work.

Example 1 Example 1

Using some plasticard, we build platforms at either end of the main PCB, just above the bogey levels - here we'll place our speaker at one end, and stay-alive at the other.

Example 1 Example 1

To give ourselves the maximum roof clearance, we just cut the exhaust outlet moulding off a bit shorter. A bit of black tape disguises this nicely from the outside.

Example 1 Example 1

Howler10 speaker (4 ohm) goes on one of the platforms, and an MGOLANG GoldCap array for stay-alive goes at the other end.

Example 1 Example 1

Wrap the MGOLANG in Kapton tape for protection from short-circuits, tidy up the wiring, and it is that simple! Our Falcon project uses Class 52 engine with Class 47 horns.

We've also separated the red lights so that these can be operated independently of the headcodes. Reds are connected to FA1 and FA2 (green and brown wires) outputs respectively, and CV changes made to control these on a different FKey from the codecode lights.
