Hot Air Balloons

[reval]

I want to animate two hot air balloons on my layout and need to know what kind of slow rpm motor would work.  I have in mind to attach the balloons to a circle of line and have the motor move them around the circle.

Would hot air balloons travel in a circle without rising and falling to take advantage of winds af different directions at different altitudes?

This would look near.

I’m not sure I get the way you want to manipulate them, could you do up a sketch for what you have in mind.

 

I have automated all kinds of things on my layout but never anything airborne.

 

This guy is my latest.

 

 

 

It gets tough to hide the movement drive systems.  The guy with the hammer is driven with a micro servo and a .015” piano wire.

 

When you get into low RPM micro motor motors the gear boxes get pretty big.  The g3.7 servo is fairly small, they can be modified to operate 360° like a regular motor.  I use a slightly larger SG90 servo as a motor to turn the water wheel for my Mabry Mill at about 5 to 8 RPM.

There is a European layout in Helen Georgia where they have or at least had hot air balloons It was called Charlamenes Kingdom.

I have seen a layout here in Australia that used a small version of the system they use for cameras above football games. It is processor controlled and uses 4 motors mounted up high, that each have a fishing line attached to the balloon. The one I saw was controlled with a joystick and there were 4 possible landing spots. As you moved the joystick some motors pulled and some released the line so the balloon could go up and down as well as along in any direction at any height. I'm not sure if you want to go to that level of complexity, but it would be interesting to play with.

It was a Faller system 131003.

I have a movie of it working.

 We hd some hot air balloons on the layout of the old club I belonged to - whoever painted the basic brown color over the scenery base got a lttle sloppy at one point and got splashes of the dark brown color ont he bckdrop, which was alreayd painted sky blue with cloud stencils. So someone painted in some balloons around them. The interesting part is that the area this happened to was very close to an area where there actually is a huge hot air balloon gathering every year.

 Not animated though.

 But - a way to fix mistakes!
