Graupner motors

Re: Graupner motors

Haz is right. Because brushless motors tend to go one direction only they would be useless for a lifter.

Re: Graupner motors

would using 2 work?

Re: Graupner motors

RC cars have brushless motors that go in reverse.
quite a lot though.
would a drill crusher really be able to crush through thick polycarb?
have RC car motors been used in combat before (brushed ones?)
thanks dave (sorry i forgot the obvious reason.)

Re: Graupner motors

Drill crusher would not be very effective, they can grab of built right but don't expect too go through much

Re: Graupner motors

dont touch brushless at all. leave it to the pros....

I never said something about a brushless crusher...

I think I was going on about the simple homemade linac in laser as the most basic weapon to have.

AS WE SAID EARLIER DONT GO INTO SPEED 900's AND GEARS!!!

ever heard of the phrase KISS??

Listen to our advice, start simple.
Drills and electronizes, make a simple first bot. Stop ignoring us we know what we are doing.

Re: Graupner motors

you would do better getting a actuator off ebay like this

Re: Graupner motors

i thaught you did Ben, oh well sorry
btw speed 900, i said nothing about them.
i don't want to use anything like one.
i am taking your advice

Re: Graupner motors

Yeah brushless motors can reverse but you need a special kind of controller to do that (which is why I said 'generally') which is why you pay so much for the RC cars with that function.

A drill motor crusher, as its been said, wouldn't be very effective as a crusher (might bend some plastic) but would be fine just to pin robots down so you can push them down the pit and such.

And he's right Ben, he hasnt mentioned using 900's for a few posts now .

Re: Graupner motors

ok i will now.shut up about brushless.
callums fw chassis that's for sale seems good to work on as a first fw.
i will have more experience if i build it myself though.
and it won't take my 7week summer holiday (God they're long) to fit speed control and add batteries.
cheers

Re: Graupner motors

yeh, callums fw is very cheap and would be a good starter for you.

Re: Graupner motors

i know i said i.would stop with brushless ideas but this is for an RC car.
1100+ watts http://item.mobileweb.ebay.com/viewitem ... 6176661487
could you use 2 escs.on each one?
this is just for extra info i am probarbly not going for a brushless drive.
although it won't cost as much as satanix, i just posted the link because it looks cheap.
edit: the motors and wheels from callums fw would be good as I'm not building a flipper.
flipper body's should have a fipper

Re: Graupner motors

First thing I notice when I click that link.

Shipping: Not Available to United Kingdom
Item location: Hong Kong, Hong Kong
Ships to: United States, Canada See exclusions

Please do a bit more research before posting things, sit down with a pen and paper and work it out for yourself then post questions about the build. It took me about 5 seconds to see that it wasn't available in this country.

Don't use brushless at all, forget they exist for the moment and use brushed motors. As a tip, if you have a working robot and therefore understand the basics about how its done at FW level people will take you more seriously, partially because of that very fact and partially because you'll see that what you're asking about wont work. Incase it needs saying in blunt terms, some people are getting quite annoyed.

Re: Graupner motors

You could easily turn the flipper into a lifter powered by a drill motor and threaded rod and nut actuator.
That would be simple and very cheap and give you a working robot.

Either do that or make a simple rammer like everyone is suggesting. You will learn a lot more from building it yourself though.

[archie2000]

Re: Graupner motors

probarbly a simple rammer
what are people suggesting as a motor for an actuator?
dewalt or something.
brushless dosent exist in my head now

Re: Graupner motors

car seat actuators are good ive got 1 in my robot and it can lift 24kg and you can pick them up for about £15
