My FF-4 Chassis build

[icrawl2]

My first build using the UndergroundCrawlers FF-4 Chassis


So far I have:

Axial axles
R2 DIG Tranny
Tekin 55T motor
Tekin FXR ESC
CC BEC
3s Lipo
2.2 Rock Grabbers

Going to get:
Clockable C Hubs
High clearance knuckles
Losi shocks
Rear lockouts

The FF-4 Chassis


The lower links are made from 10mm Delrin with Revo rod ends, the top ones are 8mm. Also the rear top links are the same length as the lower ones.

Nice start. First thing I noticed was the Bulla Ice cream in the background and thought they don't have that in the US

Keep us posted with the progress.

Seems there is a couple happening down here at the moment one of our guys hopes to have one ready for our next comp.

Looking good icrawl. How long till its on the rocks.

From what i understand Juan has sold 3 of these chassis to Australia although there could be more by now.

Not sure still waiting on the shocks and have to pay for my daughters Debutante Ball in a couple of weeks so it might be a month or 2 away.

looks good. my R2D was a loooooot tighter when i put mine in. but, i was also using the RC4WD servo mounting bracket, too...

that blue looks good, too.

I bent some square Delrin using a propane torch (not really recommended) but it did the trick I think he may have used a heat gun with a "fan tip" or a blow dryer

[dragrcr]

I have been using the microwave, it works supprisingly well, and I put the bend in it and put it in the fridge to harden it up quickly, works very well.

So how long in the microwave? Are we talking a hotdog... some popcorn....or a frozen burrito?

[icrawl2]

I just used a cigarette lighter, it's not the best looking bend but there not the final ones anyway. Once i get it sorted out and tuned then i'll make some nice ones.

I like the microwave idea, i will have to give that a try.

I put em in for about 1-1.5 min. depending on how soft you like it, I like doing it that way because the link is heated evenly, and I can usually get a burrito done at the same time

lucky i didnt get upper link screws, no biggie though
also frozen buritos rock!!!

[icrawl2]

The Losi shocks finally turned up, i'm starting off with a 500wt oil and the white springs. I am going to be making some new front top links as the shocks press on them under full flex.
