A piece of bungee cord was placed between the marker back end and the hull 
floor because the barrel part was the heavy part of the cannon, but this 
might even worsen the problem now that I think of it. Every downward 
movement is followed by a bungee cord enforced upward movement. Will try to 
add some weight to the end of the barrel.

I set the end point adjustment correct so thats OK

I'd like to keep the main battery 'clean'. I guess 12 V is a bit much for 
the servo, I might need to find a spot to hide a 7,2 V pack.

Thanks for the tips.
