An update on the model evolution:

---

So after trying out the first model in different surfaces, I thought of making few design modifications in the model.

• Initially the gear ratio was approx 1:2 but now I have increased the ratio to approx 1:11. This modification is made to make the model move more stable on uneven surfaces.
• Double beam reduced to singe beam. The long connecting rod with addition of beam for power piston looks visually good but the losses due to moving parts are notably big.
• Proper flywheel weight distribution design.

See the results in below video..
Only thing left is to add the heat shield which has been fabricated. It just needs to be attached.
