It's sure nice to see more than one company making advances in this segment of the hobby. Hopefully it will be a reliable option, and they bring on the HV soon.

That IR programmer is the stuff, I dig that big time. I would love a more portable programming option for the CC stuff, I dont like dragging the laptop everywhere.

Cool! we are back to the controllers in a bag!

i guess you need to teach those dudes we like the controllers in a housing Lutach..!

I ran the MBX5T again today, but I went a tooth higher on the pinion to a 15T to see if I could get the controller to hit it's Thermal Protection. Well it did and it worked beautifully. Keep in mind this is not the same controller that will be offered by Scorpion. Scorpion will add a larger heat sink and a fan (Fan might even be Thermal controlled). I still have the original heat sink and I will be changing it with a larger one and I will be adding a fan as well. Well motor and ESC got hot. The Max. Temp on both were 212F and the avg. on the ESC was 160.83F and the motor was 156.36F. The batteries were just warm and I put back 1639mAh after around 6 minutes of running the truck. Max. current was 85.69A and avg. was 12.34A. I don't now how accurate the min. voltage on the DPR-150 is, but the graph did not show 13.14v min. as it's says. Each pack had 11.34v in them still.

Do these have the same fets as the air version? Just different programming?

The FETs on the one I have are the NXP PHK31NQ03L. I have suggested another FET from NXP that seems a lot better as it has much less resistance then the ones there now. I have also suggested 3 or more powerboards to handle higher current. I will post some pictures of what I will do to the unit I have. Good thing my Schulze 18.97 failed as I'm going to use the heat sink from it and the fan from my Novak HV controller. I'll probably do a little box to fit the controller in and use some left over capacitors to make a big capacitor bank to see if it can help in the heat issue. John, I'm very impressed with this controller. All the safety features works, it went into the 50% power before it hit the Thermal cut off. The switching BEC works like a champ.

I have been pleased with all of the products I receive from Scorpion. Out of hundreds and hundreds of outrunners I haven't gotten one single bad one, not one blemish. Of the few ESCs they have worked great for a great price too.

I like how the owner of Scorpion seems to want to build a very nice car controller. I gave him some ideas and he liked them. After I'm done installing the heat sink and fan, I'll send him photos of it. I sent him a photo of a very nice heat sink/ fan combo and I hope he uses it. I'll see if I can do the changes to this ESC ASAP and get it out for some more testing.

Some pictures.

Some more.

And more.

Last 2. Sorry.

Now let me explain the ugliness. I was going to use shrink wrap, but most of the controllers I have with shrink wrap seems to make it shrink some more. So I had some of that Self Fusing Silicone Rubber tape here and decided to try it out. One advantage is that it will withstand higher heat and it should harden a bit in a few hours. You can also see that it makes for a much more water tight application. It also smells like my uncle's rubber factory :lol:. I will find my on/off switch and add it to the fan and use my rx pack that's already in the truck to run the fan. I don't need the rx as the BEC on this controller is just doing a great job and hasn't failed yet. Hope your guys enjoy my Frankenstein job :lol:.

What Lipo capable is this one??? Just 5S??

It is 6S. Scorpion will be changing the PCB to make it a better controller and the HV ones (12S and 15S) will be available soon as well (I'm keeping my fingers crossed for the HV ones).

Got the controller mounted and fan working. Tomorrow I ill see how it does and hope fully it will stay cool.

Just came back from a quick run to see what was improved with the Heat Sink/Fan combo. I must admit, I've extremely impressed now. The controller performed very solid and didn't get hot at all. It was just warm and I guess the heat sink/fan made the difference. The Mega is getting a beating and it is just an awesome little motor. If Mega comes out with a sealed version of the ACn22 series, I'll be adding some to my collection.

Nice! Did you get this one straight from George?

Yes, I've been talking with him for a while now and I gave him some of my ideas. Georges is a great guy and he is open for suggestions. John, this controller changed after I installed the heat sink and fan. It's a monster now. I changed a few things on the setting and I'm going to try the reverse function, changed timing from auto to 15 degrees and I will see what the Motor Start Booster will do. I hope he can use the MOSFET I suggested and I will wait to see what he says.

When you get bored with that one, I will take it off your hands if George will allow. I want to see how well it starts up an outrunner in a bind, more specifically the motors that George makes for me! I suppose I should just email him direct about it.

Which Mega are you testing with. I use Mega is some of my planes and I do like them. I almost got one for my E-maxx but went cheap and ordered a Medusa instead.

The ESC have forward/reverse/brake? If so can it disable the brake? I really think a 8S is what I need. I run A123 packs and 6s1p is a little short on runtime and 6s2p is kinda heavy. 9s1p would be just right, And a 8s lipo will handle 9s A123 just fine :)

Highflier

This controller is doing an amazing job of starting the Mega without any issues. I just ran it again and I'm more impressed now. I ran my truck on a football field and it was awesome and you can really feel the difference with the Motor Start Booster. The controller ran cool for 8 minutes as the pack dumped on me. I can't complain and it put out a max of 2055 watts, avg. of 242 watts and a max of 121A, avg. of 12A. Not bad at all. The Mega is getting a beating though.

I'm using the ACn22/30/2. Yes, the controller has forward/brake/reverse and I just came back from testing it again with the reverse option on and it works good.

Here are the Brake Settings:

1*: *No Brakes
2: Very soft brake
3: Soft brake
4: Hard brake
5: Very hard brake

*Default

Scorpion will offer 3 HV controllers as well, 2 will be 12S and one will be 15S. Scorpion will be using a better PCB for the new controllers to lower the resistance.

Are you using the 120 amp 6s version right now? Is this the same model as seen on fleabay or different in some way?

Also what is the expected cost to be of the 12s version? I assume the difference between the two 12s versions will be amperage, what will the two options be?

The one I have is the 120A 6S, but the ones being sold so far are for aircraft only. This is the only unit I know of that has the car/b mode working. Scorpion will go with a new PCB for the new units to lower the resistance. They are 1% lower then Kontronik and Georges doesn't like that. The 12S will be 90A and 130A and I don't know what AMP rating the 15S is.

So what's the word on when the car software will be available in all ESCs that scorpion sells? Also, around how much does the 120 amp 6s controller cost with the car software on there?

I haven't talked about price with them yet. I will most likely use their HV controllers for the kits I plan on making. I wanted to get the HV, but they only had this unit available. From what I've been told the new controllers will have a new PCB, heat sink, fan and from what Georges told me, he might redesign the controller to make the fan thermal active so the fan will only come on when needed. As soon as I get more info on the controllers, I'll come in and tell them. For now, I'll be testing this unit to see how it does. I will try other motors as well.

hows it work, where can i get it, and for running only 3s lipo, would you take it over a mamba max?

and your saying that your mega is getting a beating??? i have a ACn22/30/1 that i will be using. will it be too much for the motor(is that possible at all)???

I will try it again on Monday with 4S lipos and I'll get to 3S as well. Castle controllers do have an upper hand on service as Castle is US based. The Scorpion does have the wireless programming which is much better then taking your laptop to the field. I changed the pinion for a larger one to push the controller to it's limits, but the Mega is not taking that too well. I will switch to one of my Aveox 1412/1.5Y and later go with my Kontronik FUN600-17 to keep everything in the 1700 or so Kv range. You can use the ACn22/30/1, but gear it properly so the motor won't overheat. The controller starts my Mega with no issues at all and if you grab a hand full of throttle it will give you a hand full of power with no start up issues. The controller is not out yet as Scorpion will use a different (Better) PCB and a larger heat sink with a thermal activated fan. After I added the bigger heat sink and fan to the controller, I can definitely say it's solid. The switching BEC is working great and that is good as I can use my Rx pack to power the fan.

bluegrooveconcepts used the same motor in their revo geared for 46mph according to them. i was planning on gearing it for about 40-45 and keeping my 2 speed in my revo. do you think the mamba max will be fine? its only on 3s and i will probably add a fan soon enough since i have one that isnt really necesary in another car. i do want something that will give a handful of power. and then some if at all possible. haha

Yes, the Mamba Max will be fine for 3S. Later when you do want to try 6S or higher with a different motor, you'll have more options to play with.

so i should just go with the mamba max now? i wanted to wait for the MMM but dont have untill mid jun... i need to get my truck running by next weekend...

If you only plan on using 3S the Mamba Max will be your choice. When you want to upgrade later, you will have more choices to choose from.

alright. many thanks again man! you helped me pick out my motor a while back too

Glad I can help. The Megas are great motors and they deserve a little spot light :lol:.

i wish i could agree. ive had it for nearly a month now and still yet to be able to drive it... but ordering a speed control tonight so itll be running in a week!

The PS4...like playstation 4?:surprised:

Yes, the PS4.

:surprised:
