Graupner motors

Re: Graupner motors

hmm
i know they are great for beginners but i am very fussy and i want more power
is that stupid
conker couldn't push satanix very well
plus i am really understanding gears and tomorrow will make a prototype from wood
the design is like the storm 2 of featherweights
is it possible

Re: Graupner motors

well, maybe get yourself a pair of astroflights?
or maybe look into a brushless drive

you can definatly get those options for under £20 :|

Re: Graupner motors

might these do the job

Re: Graupner motors

Gimsons will give you more than enough power. Conker couldn't push Satanix purely because Conker had nothing to get underneath. Satanix has a wedge, and so it lifted Conker up, reducing its grip and thus disabling much of its drive.

4 Gimsons, perhaps overvolted, will make for a plenty powerful featherweight. Tormenta ran four 12v drills at 18v with 100mm wheels. Thing did 10mph and it had boatloads of push.

It's as much in the design as it is in the power of the motors on paper.

Remember that bigger motors often require bigger ESCs and bigger batteries = more money spent later down the line. You could run 4 Gimsons with 2 Electronize 30a ESCs and a single NiMH. Perfectly adequate for a first featherweight, and perfectly powerful.

Re: Graupner motors

harry thanks for the options but i sense a hint of sarcasm :P
plargen i think those are slightly underpowered although they are the right size quality i think they are too cheap to be powerful. it actually looks similar to a drill motor i think although Max said they were size 500
Ellis i know tormenta was very good when i saw it
it did a sort of 180 skid and then drove straight into NST and exploded every where
(that was an epic death by the way man)
ok i will see where i get with my gearboxes then make my desision

i also cam across these

Re: Graupner motors

have the same shaft as a speed 900 so could be similar to the replicas

[psycho_fling]

Re: Graupner motors

don't buy those motors unless you've asked some obvious spec questions voltage, current draw, stall current

just becuase a motor looks like a speed 900 doesn't mean it will perform the same

my advise go with the gimsons few reasons

well made
good motor setup
cheap
and they won't depreicate too much aslong as you dont wreck them

Re: Graupner motors

Seriously just go for gimpsons or 4wd drill motors as its your first bot, don't attempt your own gearing! There's been a fw storm 2, I believe it was called stiff breeze and I think it had Astros for drive.

Build a simple robot, have some fun with it, learn about more complex things, check out what other robots use and how they're put together.

Re: Graupner motors

yeah my first will be a axe bot
thanks guys

Re: Graupner motors

hi guys do ya know what the file extention the FRA forum will let you add as an image
I mean on sketch-up you can only export as .dae or .kmz both of which are not allowed
like on an image its .jpg
or i could send it to shapeways and send a link
thanks

how does this work for people
only problem is you cant see it very well

[archie2000]

Re: Graupner motors

that dosnt work does it :l

[typhoon_driver]

Re: Graupner motors

do a print screen, paste it in microsoft pain and crop it to the image then save as jpeg

[archie2000]

Re: Graupner motors

cheers i will try that
ps my shapeways account is called cooldude6617
do i need a shop so you can search for my account?
