our other option is to use a bigger, more powerful motor (like the ones eddie is using - I still can't believe the specs on them!) and pulley-drive the wheels on the shell. It wouldn't be too difficult, and we wouldn't have to buy speed controllers...

I think we can fit a motor up to 4 inches in length. We would just have to make sure our total motor+pulley system weight is well under 3 lbs and it will be a savings.

Yeah... That is true.
Whatever ends up being more cost/weight/time efficient is what we need to do...

We have literally 4 builds left(Tommorrow, Saturday, Tuesday, and next Thursday) before Miami...

We could probably plug in more builds if we need to but...

The reason I suggested the motors I did was because they basically are just a quick swap of our current setup. More expensive most likely, but it would be easily done in a week...

yeah. wayyy more expensive. And I don't know how rugged those little brushless motors are. If they're the same size, they're probably not super-durable, so we may be better off going with bigger motors. I think we should skip the brushless stuff this year - we really don't have very much money, and we don't know anything about them.

On a different note, we can't build tomorrow, but we have no school friday, so we can build friday. I also got off of work for next wed and fri, so we can build four days next week.

fuckkk.

I was expecting these little motors to work.

Honestly, I think we'd be better off conforming to the norm and using bigger motors. They're definitely going to be more durable, and easier to work with.

stay with the brushed motors for Miami, and THEN decide what to do. that way, if they do end up working, then your not out of $450 in brushless motors and controllers. if they don't work, then you still have enough time to do it for Nationals!

We don't have the funds to do both....
Not unless we get some miracle donation...
As it is this is cutting into the Copperhead 3 armor funds...

Because shipping will be $600. And registration is another $300. Plus this redesign. Plus the $400 reimbursement for Jeff Curhan(well deserved reimbursement because we would be nowhere if it weren't for him)...

We don't have the funds. We simply do not have the money... I guess that makes the conservative choice the obvious one... Two larger motors it is. Neutral

Next year we will do some research on Brushless motors.

So. along that route, which motors would be best to use? Eddie found these which have very impressive specs, but I don't know how good they really are. We could use Mini EV's too...

Well.. at $8.99 may as well just get 2 of the Duratrax and test them.

You need to do like us, every year we send out a letter with a highlight DVD to every company we can think of, cant hurt anything, youd be suprised what you get, the 20 and 50 dollar donations can really add up. Alex sent emails to over 250 different businesses and we are now sponsored by Castle, its always worth a try

I think we should use the duratrax motors. theyre cheap, so they wont hurt the copperhead armor fund, and we wont have to do a significantly greater amount of work to incorporate them. but we will need to get them ASAP.
