Servo Gearbox

[Sariel]

I should have come up with it sooner.

Hope it helps.

Genius! I could really see this working off in a RC Car.

Hi

wow - that is great bevause it keeps many things simple. It is that simpke that even myself understands right from the video how it works.

Do you had to hold the trigger down to keep the gear in 3rd podition? Because the servor always jumps back to the neutral position - 2nd gear?

Yes, you have to hold the remote's lever. You can modify the remote if it's a problem, though, put some kind of a lock on it.

Like always a very genius and simple gearbox from your hands. Thanks Sariel i will try this gearbox

Brilliant design there! Fantastic work!

[Conchas]

Excellent realization!

Alternatively you can use the PF Speed Remote to address that issue.

Very nice!

Nice solution. Is it safe to hold the servo in one of the directions for an extended period of time?

I imagine it was made for it.

This is really nice solution. Even there is that gear skipping risk under high torque it is still very nice and elegant. With PF Speed remote this approach can be used as some kind of multiplexer - one input and multiple outputs selected by the position of the speed remote.

Great, only problem is that you need 3 separate channels to drive a vehicle.

Nice ! I'm supervised I also didn't 'see' this design when trying to make something in LDD

im busy making a similar version

[Kierna]

Fantastic!

[Blakbird]

Cool idea! The one drawback I see is that the torque of the drive motor will tend to backdrive the servo. This means that the servo needs to react the entire propulsive torque. I could imagine that a high torque motor like an XL, when under load, might force the servo out of gear.

If you used the train remote, at least you wouldn't have to hold down the button to position the servo. You could dial it to where you wanted it and it would stay there.

Great design

Nice use for the Servo, Make good use of the 3 main positions using a standard remote, I like it.

Gotta try this !
