Good choice of motors, however most beetleweight wheels are a little smaller in the 35mm to 50mm range.

I use brushless drive which uses separate motors and speed controllers but is a lot more fiddly.

Hmm...I will have to design the bot up in CAD and play around with the wheelsize... i am swinging towards a pizza box type bot potenally with the wheels coming through equally as much on the otp as it does on the bottom to allow it to drive when inverted.... maybe larger wheels may be better for this?

Brushless motors huh? that does sound quite tempting... i like the idea of using slightly cheaper(they are cheaper right?) ESC's.... do they need gearing or can they connect directly onto a coupling and then onto simular RC wheels like above?

Hi there, I too use those couplings with RC wheels. And they work well enough, although they are a heavier solution in comparison to other methods.

Glad to hear the method works well. it seems the easiest to me as a newbie to get started.... heavier solution. do you mean effecting weight limits or that its a little overkill for a beetleweight?

Because of the bigger outer diameter you might want to look at the 800rpm or even 600rpm 25mm gearmotors. This will give you a lower speed but more pushing power for the same amount of weight.

hmmm... I didn't think about gearing the motors down to a lower RPM... do you not think 1000RPM motors on 60mm wheels will work well then?

Anyways, welcome and enjoy.

Thanks, i have a considerable amount still to learn but this forum is a massive archive of experience and help...

My birthday money(sound like a kid still lol) is coming together and im going to want to nail down my first set of components ready for biting the bullet and making a purchase...
