To go to the "Dark" side!

i wanna be one of them secret tester people.

It's probably too late now. I was "sworn in" back in August of last year, when there might have been fewer beta testers than there are now.

Good luck with your project. If you break it good, if you don't break it good, we'll know the strength of something. I'm actually interested in how the buggy runs.

There's only one company making a 7700 kv sensorless motor out there now, I have on good authority that despite the super high kv, they still make 87% effeciency! The company was initially going to try and adapt or use Feigao stuff, but ditched that idea because they just couldn't be as effecient as the ones they would wind up making.

Oh yeah, I've seen the 7700 motor run in a B4 recently on 3s lipo, flat out ballistic power that would make even the most hardcore nitro guys do a double take. They're stinking durable too, many HARD hits to the motor and motor guard didn't even phase it, truly amazing craftsmanship.

Hey Travis, you think Castle would still be willing to bring more beta testers on board? I got a T2 that'd be fun to get going with BL again.

Did you get to try the buggy out yet metal man?
I was looking at one for myself. Just curious to your thoughts on it.

I believe you've put it together already and its ready to run, right?

Need some pics, my friend.

For about a week I used a Speed Gems 13x2 brushed motor and a Duratrax 12t Reverse ESC that I borrowed from a friend. I think there was something wrong with the motor since it liked to overheat despite gearing changes. The Dark Impact ran well, it does have a bit of a push when you're on the throttle (all 4wd buggies have that) but its steering is pretty aggressive off-throttle. My Dark Impact has been sitting for about two weeks now in anticipation of my free Mamba Max system, and will be driven as soon as that comes in. In the mean time, I've done several things to it:
-Blue aluminum adjustable turnbuckles (the stock ones were non-adjustable threaded metal rods)
-Front universals. With this I was able to mod a part of the steering to get more steering throw, but you need universals (not the stock dogbones) to do it.
-Mounted a 40mm fan above the motor. The motor gets almost no ventilation, so this fan should help. Also, I now use Velcro to mount the body because the fan and the rear body post interfere with each other.
-Slipper clutch shaft that allows the use of B4 slipper clutch parts and spur gears.

Next up on my list of things to get is a DF-02 aluminum shock set. I've already got the springs to go with it.

BTW, RCCA did a review on it and that rated it quite highly. Now for the pics:





The last picture is the B4 slipper clutch.

And yes, I realize the front tires are worn down :031:, but I do have some Holeshots for the track :027:.

Hey, the pics dont work for me.

[MetalMan]

Are they not working for anyone else? I can still see them when I'm logged out of my Photobucket account.

[coolhandcountry]

They are working great for me metal man. I can see them clearly.
I can tell you it is sweet looking. Are you going to get a video of it with the mamba in it?

[MetalMan]

I might get a video, but my video man has to come home first (neighbor friend). After about 10mins of driving so far, the rear tires are starting to look a lot like the front tires.

[captain harlock]

Hmm, then you have a Photobucket account. Now that explains it all.

I don't and can see the pics.

i can see the pictures just fine with no problems at all.

Here are some pics with the Mamba Max mounted:


The wires are a bit too long, but I'm too lazy to shorten them right now.
