I think there was an article on this a while ago? I seem to remember he first boat I had mentioned in the mag (as a readers letter) was the first lander I made (ooo perhaps it was 15 years ago….) and in the same issue or the one before there was a 1/35 kit lander. Perhaps it was a trumpeter one? I will look it up.

A 385 motor is the thing to use…but what space do you have.?

I dare say the ramp could be made to go up and down with a bit of thought, but of course it would need a rotary servo to be put some where or other.

For working a ramp, something like

Mini 360 Degree Continuous Rotation Servo FS90R

or

might do.

The first is a servo with continuous rotation, the second a motor and gearbox requiring an ESC or switcher. Neither is proportional, you just turn it off when the ramp has got there. From posts about similar projects elsewhere, the ramp needs some extra weight to ensure that it will drop.

If it is the foot long one like the Italeri one, a 385 might be overkill. A 140/1 as sold by Component Shop might be more appropriate, and much easier to hide.

I have converted the Italieri Landing Craft.

I used two ex cassette tape player motors initially with 20 mm plastic props. But it was very underpowered given the barn door shaped bow. I changed the motors to 2 x 140's for more power. I bought a Sherman Tank kit for the load bay, this is used as the battery box.

To raise and lower the ramp door I used a small geared motor to turn 2 connected pulleys and strong thread to the door.
