Fastback II build

[2006Shelby]

Ok i ordered myself a Fastback II chassis and i have been reading on most the builds on here the only question i have is most ppl use a 4 inch shock but are they extending them to make them longer to mount them on the front axels like i see in most the builds on here and also whats a good replacement for the D-Mount since there not avaliable anymore ? Also once i receive my chassis ill make this into a build thread.

I have been running fast back 2 for quite some time. Make your own d link mount as it is a huge help to the rig. Traxxas big bore shocks with mini T springs. No clearance issues.

Yup you can fab up a D mount with ease. Just read through some of the builds on here for ideas and if you need some measurements for the D mount I or someone on here should be able to get them for you. Trial and error is about the only way to set your rig up for your liking,but there is plenty of FBII builds on here to get a good starting point from

Well got my esc and lipos and found a D-Mount also got some losi 4in shocks . Tore apart my old crawler . Will be posting pics as soon as my chassis gets in hopefully in the next few days.

Ok im haveing mad trouble with my FB II build atm maybe i have just over looked this for the last 2 hours reading on here but does the front Reg MiP drive shaft not work as in is it too long and do i need to just get the dig unit shaft set for the front and also i have seen ppl ask this before but the rear lower links are 30* bends but what is the Eye to Eye distance and also i have 4in losi comp shocks and the seem really short for this build. Im just frustrated atm and been reading for so long not finding the answers im looking for any help would be great. thank you.

Yes you need to shorten the front driveshaft...I just cut mine down with a dremel. This chassis is a 60/40 set-up meaning that the chassis is not centered but moved foward between the axles to achieve a greater breakover point.

This is the premier thread for Fastback setup. Somewhere in there he mentions link length...although I have looked a thousand times and cant find it...
Underground Crawlers Fastback chassis

DickyT also has a FF-4 thread that I think mentions the correct length as well.

Now my only problem is shortening that drive shaft.

Dremel and a cut off wheel worked great for me.

Atm with only 5 inch eye to eye links that are straight yes it fits with some shaft left over but im gonna order some bent links for the front and rear tonight from a derlin dealer.

[2006Shelby]

Couple pics not thats great so far and oh mind the messy area its my kitchen table my garage heat is out so i had to move to the kitchen for now.

[2006Shelby]

Also and yes that is a Bender's SWX its sitting on and tires still touching the table its about 3 1/4 inches under the belly of it with just straight links on it its a work in progress.

[2006Shelby]

Well made a lil progress today got some stand in rear links untill my others get here and fixed my shock problem i was having and cut my front driveshaft down to fit also.









Any suggestions or comments on it are greatly appreciated i like to know where i went wrong on something. Front lowers are 4 1/4 E2E and rear are 5 1/16 E2E.

[xjcritter]

you going to try your hand at fabing up your rear upper mount or did you find one?

[2006Shelby]

i actually found a d-mount its in the mail atm on its way to me was the best 10 bucks i ever spent lol.

[xjcritter]

Have to agree with ya. Im using my stock plastic RTC lower links as rear uppers. Might not be exactly perfect but it keeps the pinion up nice and high. Oh a free to
