Actually the esc brakes work fine on my redcat/axi setup. But the clutch idea would be nice. I am going to do a twin outrunner, twin hv85 setup. We will se how well the castle air controllers work!

With mixed throttle you could have variable braking or throttle from front to rear.

I have read on the Croco site and other sites, that you want the wind resistence to be as low as you can get it without resect to how many turns it is. That is a goal with motor winding.

Manufacturers make compromises at the cost of effeciency with motors. Small wire is used because it is easier to work with. The larger wire is harder to work with but produces a wind that has a greater Cross Sectional Area. Less Resistence. :yes: This Raises the Power Handling ability and efficiency.

I also feel like they steer away from the Wye wind because of the added termination point that can create problems if not done correctly.

They settled on a Delta termination, because in their testing with a prop, they are only measuring thrust at top speed and total amp draw.

They don't start the motor under a load at all compared to a Monster Truck. The amp draw doesn't come up hardly at all until some rpm's come on to the prop and make the load.

This makes the Delta wind easier and more profitable for them.

I have reached a point where I need a data logger. I have a brand new factory delta wind in the 3530. It would be VERY interesting, to collect some data from several runs with this custom wind. Then put the factory motor back in and collect some more data. Comparing that data would tell alot of things I'm sure. The difference is enough to see for sure. It performs alot better.

I put the factory wind on 6S one time and blew the transmission on the first run. I'm tempted to bump up to 5S on the custom wind, but I think that would be enough to make the transmission go Poof. I'll try to get some video soon.

The new E maxx should be hitting the market anytime. One of them has my name on it. I'll do this conversion with it. A transmission that can handle 2 1/2 times the torque of the original? Let's make that thing dance! LOL

How do we figure or gauge efficiency of a motor?

Huh? What do you want? Build you what? LOL

The problem with a clutch and this setup is, current clutch designs are up on the factory drive train where torque levels are much lower. How do we design a clutch that is inline with the shaft to handle the higher torque?

ESC brakes work fine with this setup. I've never had a problem with that aspect.

Hi Linc,

I'm very interested in what you're getting ready to do. Please keep us posted. We need pics. :yes:

If you can swing it, go with the HV110's. I've often thought about the Castle Controllers, but the lack of reverse and suitable brakes steered me away from them.

I believe with the mechanical brake setup that you have, they will do great! :yes:

If you really wanted a clutch that could handle the torque load, a modified baja 5b clutch should be able to hand an outrunner, it seems to cope with a weedeater motor in a 20lb truck!

Any specific reason to go with the hv110 over the hv85? Do you think that I will be able to pull more than 85 amps out of those outrunner with only half the load? It will be setup for an road running, so the rear motor should not have to work as hard, less weight transfer due to lower cg and stiffer, short travel shocks.

Well I'm not sure, depends on the setup. I am sure my Revo is spiking up more than 85 amps on take off. It performs much better with batteries that can deliver more current.

I like to over size in the ESC department if possible. You can't have one too large as far as ratings go.

That's going to be an awesome setup.:yes:

It should be pretty cool, would be better if this guy i know could custom wind my motors so that they have lwer internal resistance:wink::whistle:

I'll try the motors stock first and see how they perform. :tongue:

I received my fan yesterday for the redcat axi and plan to do some more testing, and a new chassis layout with more permanent mounting!:mdr:

Let me do some more testing, get some practice in and I'll consider doing a custom wind for you.

I intend to do a Wye wind on the 4130 for my Revo. Let's turn it up and see what happens. :lol:

My method of doing the Wye termination needs perfected also. In the 3530, I had to bring 3 groups of 7 - 22Ga. wires together. Solder a permanent connection, while having each of the 21 strands pulled tight. That's hard to do. This connection can't ever touch anything either, or an internal short will occur.

I'm thinking about using a miniature "hog ring". Slide the hog ring down onto the strands, pull each strand tight, then clamp the hog ring. At this point, cut the strands off with a dremel tool even with the top of the ring. Then cap the entire thing with solder. This connection would be small in size and alot better. The space to do all this in, is already pretty tight.

@JohnRob - Any thoughts or suggestions on the best way to do the Wye Termination?

I think your idea of a ring would work well. I would use a zip tie to hold it all and solder, then take the zip tie off and epoxy the winds tight.

E maxx Video's
 

I got some video's of the E maxx with the custom Wye wind.

Let me know what you guys think. :yes:

In, my opinion, your Maxx is very cool :mdr: It has a lot of torque and is accelerating really fast. :yes:
But i would use other tires, it looks like they are not the best ones for this type of surface....

I hope you understand my poor school english :whistle: :lol:

Way cool!
 

Looks great. The Maxx always was fun to drive, not too stable, but drive-over anything (almost). Check out my truggy wheels with Bowties if you want some better grip. It looks like you've got the acceleration nailed and really good control. I am so jealous of all that nice dry, snow-free ground you've got there. We have another storm on the way.

I ran my Maxx last night at an indoor track. Kept it in 1st gear and it was still too fast for the track. Really nice and driveable, smooth power, good brakes (The sound the ESC makes under braking makes me kind of nervous). No problems at all, just fun to drive. Hard to control in a small space with lots of jumps though, I had to pull it off the track after I ran over a couple 1/10ths.

From what I've seen so far, I would not hesitate to order whatever new toys Sikeston34m comes up with. When there's a direct drive that works, sign me up!!

How do you link the video to YouTube like that...
I like the Video bro.... is that a stockie E-Maxx?...
