Designing my 4wd belt drive 3lb beetle weight

Thanks I'm going with the motors that you listed, I like that they are smaller and weigh less and the price is also good.
Do you normally use 2 or 4 motors or 2 motors with front belt drive, is their enough room for a banebot hub and a pulley?
Do you know if that seller combines shipping?

I believe shipping is combined, but I'm not sure.

I used 4 on a Rammer/Wedge. Power and speed were good with 1 7/8 Banebots wheels, the the 4mm BaneBots hubs fit nicely on these shafts. If you plan to do alot of pushing i would reccomend 4 as I was about even when pushing other wedges, and dominant vs spinners.

Qualitatively I think they are about as powerful as the B-series motors, slightly bigger/heavier, but at 1/4 the cost.

Edit: missed the part about the pulley. The hub itself barely fits, so i don't believe it would work with a pulley.

I asked the person on ebay with the slightly lager motors attached if they would put everything I order in a 4.95 small priority flat rate box and combine shipping and only charge me 4.95. So I might be able to mount a smaller powerful 25mm motor , maybe speed 280's or speed 300's.

Idk about the numbers but I would assume the for the weight of shafts pulleys and belts it would be a better option to just run 4 motors and have the extra power

That's what I'm planning on doing I'm just trying to find the right gearbox and motor to fit into my design.
Here's the gear-motors that I think I am going to use but the motor is a little big long so I'm also trying to find a powerful smaller 25mm diameter motor to swap it out with.

And I think I will use this 100 rpm gear-motor to power my lifter assembly. http://cgi.ebay.com/DC-12V-100RPM-Very-High-Torque-Gear-Motor-Hobby-New-/300450318465?pt=LH_DefaultDomain_0&hash=item45f43c0881

Well I ended up buying 4 of the heavier gear-motors from the united states for $10 each and a 100 rpm (for the lifter) , The day before yesterday.
Then yesterday I found the smaller gear-motors from hong kong for $6 each with free shipping so I bought 8 of those to.

I have plenty of motors now.

Does Anyone know where I can watch the old Robot wars episodes or the old Battle bots episodes or something similar, I have Netflix but I didn't see them on there.

Ok well I finally started building my robot, the design changed considerably it's now made out of aluminum that I used a bender to bend and rivet for the base.
The top will be made from aluminum too, in the shape of a 4 sided wedge.(I might weld the top)
I will cut 4 holes in the bottom and mount the motors inside the box (so their protected).
(it looks thinner than it really is, And I will run it through tests before I take it to battle)

I will use 4 1000 rpm gearmotors
Would the banebots 3-9 amp esc work best for this?
Also I want to use a pistol grip remote instead of the dual stick so I will need a v tail mixer, could you recommend one?
How many mah do you think I will need to run 5 min?

That seems way to thin to be a beetle

agreed. not sure I understand how you plan on adding the wedge to it either

Does anyone know the stall amperage of the 1000 rpm gear motor?
Is their another esc that would work?

your just asking for too much from a single esc

what were the blue banebots? the're another controller that might have worked but have been discontinued

I might go with the sabertooth 12 (it might be able to pull enough amps)
Would the rc edition be enough?
Then I wouldn't need a v tail mixer because the sabertooth has the dip switch, so I could use a pistol grip remote right?

What do you recommend then, their has to be some esc that I can use for my 1000 rpm gearmotors?

I posted a few post's back that I wasn't using the 3-9. I am either going with the sabertooth 12 unless someone has a different solution.

Alex basically restated what I said for a reason. 4 banebot 3-9 would be perfect for your application.
I wouldnt recomend using any DE products for combat robots. There esc's just wont work with dsm technology and they arent built for the abuse.

Why are you going to use 4 BB 3-9's as they are the correct solution for this?

Would I have to splice the jr servo leads together?

that or just find some splitters

Could you please explain this? I have not had any real issues with the sabertooths that I haven't had with the 3-9s.
