New ESC and it's looking good

[johnrobholmes]

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.

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 . 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 .

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 :)
