Small progress update

Tried some different gearing on the tank this weekend, using Mecanno cogs to double the input speed to the gearbox, the idea being to make the tank twice as quick.

Sadly, there's not enough torque in the engine to make smooth turns with this arrangement, so I've decided to revert to the original 1:1 engine to gearbox ratio. No Speedy Gonzales for me, by the looks of things.

Also, I've noticed that there's quite a lot of oil in the steam exhaust, so I'm going to fit a Condenser to clean up the steam output.

Now, this is more like it

I started again with the Regner powerplant, and it's much, much better. And cleaner, too. There were a fair few difficult moments, especially when I had to silver solder the pipes from the boiler to the engine. Got there in the end, though.


It runs pretty well. The boiler and gas tank are mounted on a plate above the suspension, and the radio gear is held above the gearbox. The only exception is the steering servo, which needs to be on the same level as the clutch lever.

Time for a good few trial runs and then a strip down and rebuild once I've decided what to do with the bodywork.
