WHY DIN'T ANYONE REMIND ME THAT THE WHEELY KING GETS 20MINS STOCK????? I FORGOT.... LOL, DON'T EVEN BOTHER READING NOW THAT I REMEMBER THAT
this is my second thread that was useless.... i feel foolish now :(

well, I tried a searches. But so far I’m the only one whose has don this. if there is thread on this.... it not a huge biggie

THIS IS A ROUGH DRAFT OF THIS. JUST WANT TO SHARE MY MAIN IDEAS BEFORE I GET DEEP INTO THIS.

here is something i used on a mini rc. and i might use on a full sized maxx (with heavier duty parts)

this set up is perfect for lo speed, and long runtimes. Make good since for crawling

now, what happens is, instead of a speed control. you use a direct connection from the batteries to the motor. then you break the connection with a switch. A servo hit the switch. You can now use a low voltage, lo end motor. Lo voltage mean less batteries, so you can get more life from the same amount of charge time. i shale list they pros and cons

single speed (CONS):

need to make this setup
only one speed.... some won't even notice this difference

got to get: low voltage motor that still has a lot of power, you'll now need a receiver pack, and you got to make a motor mount.
the switches, wires, and mount to servo need repairing and replacing often, but it's REAL easy and cheap.
the hard part is finding the stuff.... especial the motor. but it's still not bad.

Speed control (CONS):

the ability to use the throttle position are often un used, with some practice driving on single speed, you don't need them.
expensive.... for the control and the motor (but easier too find)
not always efficient.

Single speed (PROS):

you don't need as many batteries, so basically longer run times per charging
with some practice you can drive it using a high speed setup. (but it's best for low speed)
lighter.
Cheaper
lighter (...or heavier)
the runtime is the best, I say it twice.

Speed control (PROS):

chose between full or idle wile driving
***********more popular.
les maintenance

as you can tell I’m favoring the single speed design....

some_guy · 08-27-2007, 04:18 AM

i think the reason no one has done this is because they like to be able to control speed

i know personally i like to be able to lightly touch the throttle and have the car crawl then get onto the road and go flat out or even grass between rocks

but that's my opinion others might differ

also the pro's you have listed for the single speed aren't that great
firstly it would be bigger than my tr2 and would probably weigh about the same
it would be harder to mount
also because you need a receiver pack it would be heavier

theshimonator · 08-27-2007, 04:22 AM

i think this has never been done becuse you need to crawl slow. except you need to sometimes get some good wheelspeed to make it up somewher. so in my opinion this is a bad idea and i don't think it will work. sorry to burst your bubble.

traxxas junky · 08-27-2007, 09:52 AM

hmmmm, well it's been working for me, very goood. I don't have anypic or vids, but so far i think it's a tun better.

Kamikaze · 08-27-2007, 01:04 PM

Sounds like a 1/18 nylint. Why would you want this again?????

Thorsteenster · 08-27-2007, 01:12 PM

ESC pro:
Reverse!
The whole thing behind hobby grade RC's is proportional control which isnt covered with an on/off switch. Most obsticles your nopt going to want full wheel speed on.

WheelChair · 08-27-2007, 01:15 PM

Why don't you just use a servo control board for a ESC?

If your hooked on single speed on/off, you could add resistors to slow it down more.

On/off motor control makes no SENSE to me. Way too jerky for crawling.

It would take away from the realism of wheeling.

Thats my $5

Oh no.....is this M715 reincarnated?!

WheelChair · 08-27-2007, 01:36 PM

If you have a 6 cell 3300, you have 6 times 3300mah and thats 19800mah.

Now take a 3 cell 3300- 9900mah.

I would like for you to explain to me how you get a longer run time out of 9900mah then opposed to 19800mah???

Your whole post does not make sense to me.

Half of the sentences don't even follow proper english, but that I can understand.

Its the concept of it all.
You lost me.

Big Mike · 08-27-2007, 01:39 PM

So - you use a servo to close a switch and POW instant full throttle?

That would not even be an ideal scenario for drag racing.

How on earth is it going to work for crawling??

There's a good reason why some of these guys have experimented with every esc known to man. And the same reason applies to why companies like Novak are developing crawl-specific esc's.

Low-end CONTROL, plain and simple.

As soon as you close your servo actuated switch, you'll have max power applied to your motor. Which means you have mad wheelspeed if you have no traction, and a rig that leaps forward into terrain willy-nilly like a scared frog if you do have traction.

Get some vid posted up, cause this I have just GOT to see...

Battery pack cells are wired in series. The voltages add but the capacity stays the same. 6 3300mAh/1.2v cells wired in a pack will give you a 7.2 volt and 3300mAh pack.

I can't understand why a single speed ESC would be useful at all.

WheelChair · 08-27-2007, 02:02 PM

Oh ok, well then I must have remembered wrong from electronics class...
I still don't see how it would last longer though...

I don't either.

traxxas junky · 08-28-2007, 09:17 PM

**EDIT, WELL RE REREAD THE NEW TOP OF PAGE**

i could get a a vid? but i only did this on my mni qake. before i made a big version on a solide ale 1/8.

but i mean, i'm going to trust that you need to go fast when you crawl? and go slow. My set up could only go slow.

so thank?a

?

oh and it lasted longer becase you could use a low voltage motror, so you wouldn't need to use as manny cells. less cell mean less charge. So for the same amount of charge your getting twice the run time.

War Pig · 08-28-2007, 11:28 PM

Dude, you need to shut up and go buy an ESC. Learn to spell and punctuate, too.
