Rear suspension on a bit?
 

Okay I got this idea from my Epoch (if you don't know what they are, look on the forum, they're awesome).

Why can't a bit have a T-bar rear suspension?

I just cut the sides of the chassis as you see, and make sure to leave the bottom whole so you can still use the normal charger. I decided to use a piece of good ol' Oak for the mounting block. You could use plastic for lighter weight, but the oak is not too heavy, and I haven'e seen any wood mods yet.(haha)

Okay, so I used a rear axle for the pivot rod and ran it trough the wood block and epoxied the axle to the wood, and the wood to the front piece of chassis. If I have calculated and measured correctly, I will now have the same amount of suspension travel on both front and rear. I need to put some coil springs in front, and use a single coil compression spring for the rear. I may have to make a custom rear spring out of small guitar string.

The project is on hold, 'cause I'm bored with it. I'll try to finish it soon, though. The joint is tight, so tracking should be spot on, and there should be enough room for the cell with the PCB flipped upside down. If anyone does one of these before I finish mine, lemme know how it goes. I love the thought of full suspension!!!

woooooo
 

very cool
keep us updated dont get bored.:D

Go for it! Nice!

I was wondering; at the scale we're dealing with, and the average stresses these cars see when running, if a piece of foam rubber in there might give you the kind of action you're looking for in that confined space instead of a spring?
I'm sure different kinds of foam would give differing responses, but one might work the way you want ot to, singly, or in layers.

some other guy did this on the "other" forum but it was crapily done. hope everything works out for the best but since theese bits are so small the suspension wouldnt really help that much wouldnt it? unless you drivin your bit off your table ands it always landson its wheels thats really the only way it would. cuz there not like the 1/10th rc's

Suspension on the rear of one of these cars might help.

I watch the rears of my cars hopping up all the time on my kitchen floor.

I was thinking foam because of the limited space, but it looks like the space has been opened up by pushing the battery forward or something, it's hard to see.

Actually, I may ditch this chassis for an extended one, or a Zap chassis. (more room) The reason being I usually can't get my single cell cars going fast enough to jump very high, or to accelerate hard enough to get any wheel hop. I can't hammer my tricell booster Zap all the way on my kitchen floor tight weave carpet, because I get wheel hop like 1/2 inch high. Rear suspension may help alot. I also jump my multicell cars like 5-8" tall and 1-1/2' long. The landing 'may' be smoother, I dunno. I have noticed that with the front suspension, when I turn hard one way or the other, one of my rear wheels is off the ground. (the inside one) maybe I can get a bit better tracking if I can make it flex a bit more.

The foam idea is fantastic, if I can't make a coil light enough, I may try it. I want about 3/4mm to 1mm of sag in the rear. That's usually how I set up the front.

Cool mod! Sounds like it will work ok.

ive done it
 

yeh i did that like 2 months ago heres a pic

No offence and all, but that looks like hell..... And I don't get how it is connected to the rest of the chassis. I see that there is a spring on there, but is there a part under it?

nah it auctually works really good the spring is bent downward
at and angle and its kinda stiff

Weird, it looks like the spring is too small too be stiff.... Cool though!

I only see one problem; when you use a body, it'll lock up the suspension!

Never thought about that one...... Good thinking! And on the second one, the dam body wouldn't even fit on :p

hmm... i would REALLY wanna see this work... cuz i hate the harsh, hopping rides that lowered cars have to deal with...

maybe... you know the slots that the rear axle goes in? maybe drill them higher, but stuff it with foam, and very, VERY smooth film where the foam contacts the axle.. it seems much more simplistic, although im deadly afraid of trying it...

but this way, the body would not lock the suspension... and you could actually get the body on..!

feedback anyone?

That wouldn't work because the gears wouldn't mesh correctly.
