Graupner motors

[razerdave]

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

would using 2 work?

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.)

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

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.

you would do better getting a actuator off ebay like this

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

[razerdave]

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 .

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

[jonny]

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