Electric flipper?

[mattsdragons]

just been reading a few of the old RRC articles and ive seen that he used a wiper motor on a rack and pinion system to build a flipper

just getting opinions from people on if a modern version (speed 900 maybe) with a similar type of system might fair?

Re: Electric flipper?

The selfrighting action of Kasheis axe is rather strong.

So, with the right gearing and leverage, a fairly fast lifter or low power flipper ain't unachivable.

hear is were i got the idea, it could work

Re: Electric flipper?

What motor/ratio combo would be recommended to not only flip sufficiently but self right?

Re: Electric flipper?

Kashei used a Speed 900 @ 19.8V with a 20.25-1 gearratio on a 12 shaft.

Re: Electric flipper?

Would using a timing belt on the final stage of reduction be an idea to give the Nike a but of room to slip at full extension?

Re: Electric flipper?

Timing belts and slip in 1 sentance... nope. Timing belts that slip ain't good conduct.

V or O belts on the other hand.

Re: Electric flipper?

Care to explain how a v or o belt is better and will still slip?

[maddox10]

Re: Electric flipper?

Because a timing belt is made not to have any slip. Maybe the shape of the teeth?

A V- or O-belt inherently, due the profile-less design, have the ability to slip. Not intended to, but still.

Yet, would it slip under load?

Re: Electric flipper?

If a timing belt slips, especialy under load, it's a bad design.

Re: Electric flipper?

As long as I design it properly it might work, may be onto something here

[maddox10]

Re: Electric flipper?

If you design a setup that uses a timing belt that has to slip under overload, you're including slip clutches.

Using a timing belt in a set-up that needs slippage, is like using Big Ben as a stopwatch

Re: Electric flipper?

It depends really, I could just use gears and use a ESC that has automatic return?
