Although the attention on this forum is currently drawn to the TC5 challenge, I hope that you still might be interested in another c-model, this time built without limit of 600 pieces. So, here it is - a heavy duty diesel-powered forklift made of 42009 set.
Features:
3-section mast;
mast extension & tilt (obviously);
working steering wheel & HOG;
fake piston engine.
The key feature of the model is not only that both main functions can be operated simultaneously, but they are also reversible, e.i. you don't need to use the polarity switch to change the direction of the movement (of course, switching polarity still works). It led to a bigger gearbox and more troubles during design, but it was worth it. I also tried to reduce color mess as much as possible, but a bit of it still present (well, it should be acceptable for c-model, right?).
See model's page at Rebrickable for LDR file.
