But as of the neutral position, could dragbrake be applied at that position?

I thought about that when I saw the photo of my ESC, but I think it might be a little comples as the Mamba uses a different MPU.

Anything new yet? I got my Neu 1512 1.5d yesterday, and now my motor temps are down where they should be, but my MM is hot, hot, hot. I can get it over 200 running short bursts for about 2 minutes in my living room. Defiantely time for a new controller. Let us know how your project is coming.

I was hoping it would be done a couple of weeks ago, but the engineers had trouble with the car software. I will give them a call tonight to see what is going on.

Great work Lutach!

though the proportional brake seems to be a PITA to all the engineers. Did they took an existing design and simple added a bunch of FETT's?

I got some help from someone in the rumrunnerracing forum with the information the engineer was looking for. The design is very much like the Schulze 40.160 controller, but it seems like a simple design compared to the Schulze.

Bad luck is just raining on me this month. The engineer said he is really having trouble with the car software. He said he can have the airplane version delivered right away. I can't have that, mainly because he said he could do the ESC for cars. Maybe I just jinxed myself on this one. This is just one of the problem I was worried about. The good thing is that all the controllers are done, but they just need the right software.

Well, don't give up... this has been a common obstacle for all BL companies. Some are still trying to get good software after several years of product.

Xtremespeed · 09.29.2007, 08:12 PM

Well put. Keep the faith man. We need something better.

I wish I had learned Programming and Electronic Engineering when I had the chance.

I like to keep you all posted on the situation with the 200A controller. I asked the engineer to make 4 200A controllers, but he used sample boards and the unit(s) that was tested failed. Now I told him that is completely messed up since he said he could do a 200A car controller. He feels better doing a 100A controller, but I asked him to make a few 100A and some 80A and 60A controllers. I'm also waiting for another company to send me one of their controllers so I can test it. This one seems nice. It can use sensored and sernsoless motors and should come with a program box. Now the messed up part with this one is the fact that I missed the first delivery attempt on Friday and now it's past 7PM and I'm not sure if the driver will even show up today. I called UPS and they told me it's up to the driver now if he wants to deliver or if he wants to go home. Oh well, I hope it gets here LOL. I have attached a picture of the controller for you all to see.

Looks nice!

whats the cell count on them?

It can handle 2-4S lipos and it is 120A. I was told to keep it at 2S though. Kind of strange, but I will use it in my TC3 with 3S to see how it will do.

Seems like they are kinda balking at the higher voltages. Come one 6S (or more!)

I originally asked for something that can handle 12S lipos, but they want to see if their is a market for this one first. They said they can make a HV controller, but I have to see one first before I can say anything about it.

When do you think they will be availible? i think my competition buggy needs something like that ^_^
