MFD F2 Bodyless Chassis Rebuild

[mfawv]

So, to start out, yes, i know i misspelled bodyless , but i can live with it so i hope you can too.:lmao:

Let me start out with a history on the F series chassis. I designed the F1 and ran it for a few months but wanted more angle on the skid, so came the F2. I lightened up the F2 a bit and so far am pleased with the performance of it.

Now to the important part, this is a rebuild of my current comp rig that I've been running a prototype chassis on , but since its the same geometry i'm not worried. Yes, i will be comping with this build rig.

The parts list:
Berg V1 axles with drilled and polished gears, also shimmed for less slop
Mann 2nd and 3rd gears
Clover Customs rear tubes
Axle Master rear axle
SDS super 300's for berg
RC Bros zero ackerman over sized bearing knuckles
Tekin FXR ESC
Punk dig switch
Spectrum 3100 receiver
Futaba S9157 servo
Racers Edge servo horn
16GA wire for motors
Brood Apocalypse Type S HHK epoxy balanced 35t motors
Lunsford Ti links upper and lower
Big Bore shocks with Integy caps , Jeepin Doug mini-t spring cups, and mini-t springs, red up front and orange in back
D-lux knuckle weights with 1 300 ring and 3 100 rings
VP V2 1in. wheels in rear and V4's that were bent so i modded them to work again.
MFD custom triangle offsets
MFD berg 4 link mount
MFD F2 bodyless chassis
Aluminum and Ti hardware were ever i could use it.


Now for some pics of this great list of products from some great vendors.

Nice Cap'n get the thread going i already see things i wana do to your cases an its not decking them..:mrgreen::mrgreen:

Great looking little tidbits on this thing. Those triangle hubs are pretty slick. Are those integy shock caps made specifically for the big bores? Amy reason why you cap modded those instead of the stock caps?

Its a stock integy shock cap i did the same on my shocks. It just has to be shortened to seal rite. I did mine this way it was a lot better looking than the cap mod i think. An the stock caps seemed to bind up on mine a little when articulated so i did the same mod only cuz i had the shocks laying there not big used. That an the stock shock caps did not have a ball on it its going to travel that much more than a stock big bore cap will.

I hope this helps."thumbsup"

i had to shorten the length of the cap so the diaphragm would seal. yes, the reason is the integy caps have the same threads and a replaceable ball end. it works out well. "thumbsup"

well im up late so im workin.

got the chassis together.

 

[mfawv]

so in this picture you can see that the chassis plates are pretty thin. this is a set i had made out of 3/32 delrin. its not as ridged as the 1/8th in. delrin but i'm going to try it any way. im used to a very rigid chassis to leave the flex up to the shocks, or should i say articulation up to the shocks. i always thought that if the chassis flexed then the rebound would cause the rig to be inconsistent. we will see on that one. i am going to comp this rig and test that theory for my self.

i have noticed that some chassis have a bit of flex and some drivers like it. feed back on this topic would be great."thumbsup"

i also shortend the cross braces from 2.5 in. - 2.3 in. so the shocks lay over a little more.

 

[mfawv]

the next two pics show the 3 hole locations for the cab so it can be a 40/60, 50/50 or 60/40 set up for the lower chassis and the cab can stay 50/50 to keep the shocks @ the same angle front and rear, give or take a c-hair depending on the setup.

this is how i like to run mine. "thumbsup"

 

[Harvo]

I don't like chassis flex for the reason you mentioned. It looks like you have enough braces to keep it under control though.

Are those little wheels to keep the chassis from getting snagged during rollovers?

 

[Brackett]

Your topper looks very close to what I had in mind for making. Would like to see a pic. of it from the side view!

ya, the braces are well triangulated to not allow flex points. even with 3/32nd in. delrin upper and lower the chassis has very little flex.


that exactly what they are for, i got the idea from J-Fab Nor-cal.

thanks for the ?'s

Guess I'll have to do a build now too. I'll try to get to that next week.

Looking good Mike!

What are the two things on the back chassis brace?? Wheelie bars? :lol:

just weighed it and my RTR weight is 5.406 lbs.

my balance point is about an 1/8th in. in front of the front lower links.

thanks Kris,
it was the most work i've put into a paint job but it was worth it in the end. i don't want to scratch them up now."thumbsup"
