My 3906 Mutation

[redshift]

About 3 years ago I inherited a 3906 from around 2000, an oldie. It broke often, shock towers, bulkheads etc. and the drive to my LHS (one hour each way) was getting old.

So I decided to use the drivetrain and suspension and start from scratch. My overall goal was lowering the C.O.G. and roll momentum without losing any useable clearance, and had to be built like a brick sh-thouse...



It's a perpetual work in progress with many non-final parts but here it is.....

Is your avatar the only picture?

Ok let's try that again...

[brushlessboy16]

[bdebde]

WOW, that looks gnarly

I thought Brian was going to hit you with the "this thread is useless without pics" line.

Sorry guys I'm havin some trouble with this uploading...

The lowdown:

1/8" aluminum and lexan construction
Maximizer beadlocks, Zombie Max tires
Bigbore shocks, 8.5# Trinity springs single hole pistons and 45W silicone
3906 trans, still 2 speed with UE idlers
Full CVD and RPM carriers
Revo front diff, TMaxx spool & Integy aluminum case
Original short Emaxx A-arms
Spektrum DX3.0, Feigao 9XL, Mamba Max, 2x2S MA6000 & 2x2S FP 4900

Will post more pics, and a simple mod for beefing the shift linkage

Unique! I like to see real innovation like that!

[redshift]

First the shift linkage, all of you who had the double-spring overthrow linkage know that it's gonna get sticky, and one mis-shift is all it takes to wipe out the dog and whatever else, so all I did was figure my exact throw needed (with the TQ radio, which doesn't have throw adjustment) and used a piece with a slight bend for some give, but you will get positive shifts everytime, which is just peace of mind now that it has some @ss lol.

Some guts pics

Forgot to mention it's 14.5 lbs, driving this thing does take some finesse, but it has a real presence lol.

Now that you have some pics, it IS very nice. Sturdy and pretty too!

Although, you need to get rid of those pesky fans.

[redshift]

Thanks for the comments guys!

Brian, the fans are out of necessity because there is little airflow inside, and I like things to run nice and cool, so far MM temps are no higher than 110F, 9XL stays around 140 and the fans kick on 8.4. With the 6000's I can get well over an hour, the fans and led's consumption is very minor with 12 aH in battery lol. I definetely notice more punch with the FP packs, but the MA packs are like bottomless, I don't think I've gotten them below 7.2v. It's geared 20/64, which I thought would be tall, and it is good for 35, but I am underworking everything, which is working out very well, and I could go to 26/64 no problem, The Losi Zombie Max's stand it up in wet grass, I love the hook, but they balloon at relatively low speed and they balloon funny because there's no breather holes in the rims, and i'm not sure I want to. The truck 3 wheel steers, so I can get away with posi rear end, it really does handle remarkably well, it is not roll prone, but it is cool to see the inner rear pick off lol.

OMG this is one sick mutation....thanks for sharing

[What's_nitro?]

Awesome! It looks like a sci-fi moon buggy...

Love the custom work on that one!! Looks like it belongs in "Robocop".
