These have somewhat become the default 3lb gearmotor:

The FingerTech TinyESC should handle them decently with the included .01uF capacitor- http://www.fingertechrobotics.com/proddetail.php?prod=ft-tinyESCv2

http://www.botbitz.com/index.php?route=product/category&path=59 also has some decent esc's based off of hobbyking brushless esc's.

Do you know how many amps the gearmotors draw?

I ordered a pair to have a look see, but didn't find that info on the kitbots sight

Thanks

I haven't really seen proper specs anywhere, they're slightly modified/tweaked gearboxes from china/ebay that seem to generally do well. On the fingertech site they've got video of a test and mention that the stall is around 5A ( http://www.fingertechrobotics.com/proddetail.php?prod=ft-tinyESCv2 )

This is a much harder question. I've had a good deal of luck with the Plush series esc from Hobbyking ( http://www.hobbyking.com/hobbyking/store/__186__182__Speed_Controllers-TURNIGY_ESC.html ) so I'd lean toward giving them a shot in a beetle if you don't need reversing. Pete (Kitbots) uses a Plush 25 on his 3lb bar spinner kit

As far as motor, there's a ton of options on Hobbyking. I typically replace the shafts with hardened O1 tool steel (mid-high 40's HRC) to get some serious toughness that the stock shafts often lack. Something in this section will probably be about right- http://www.hobbyking.com/hobbyking/store/uh_listCategoriesAndProducts.asp?whl=XX&idCategory=521&v=&sortlist=W&LiPoConfig=&CatSortOrder=desc

I think this is somewhat close to the one he uses in his kit- http://www.hobbyking.com/hobbyking/store/__18225__Turnigy_D3530_14_1100KV_Brushless_Outrunner_Motor.html

i have one of these in my 3

yet to detonate it.

1000rpm motors with 2 1/4" wheels at 3s is a really nice speed/power combo.

I've been trying to get a hold of the Botbitz people so as to order a few modified plush10's, but no response
ANy one ever order from them (australia)...if so, how long does it take to get here and how much does shipping cost?
Can't find anything else even close, pricewise ,etc.
Or...anyone have the code to flash them to brushed mode?

any other options...I need something very soon

thanks

I think you can find the software and flash instructions on the robowars forum http://robowars.org/forum/

Working on that, but I'm not sure which firmware version to use, just yet.
In the meantime, I ordered a few escs from Botbitz...

thanks
