favorite position for suspension links

[EGRESSor]

the steel axle crawler

i´m new on crawling
have build my own axles for a homemade brushless crawler

but where is the best position for the mounts ?

 

[bRIBEGuy]

Nice lookin' axles there man. Are you trying to figure out where to mount the links on the axle itself, or where to mount them on the chassis?

I dig the brushless idea............but you may find its a lil' bit on the "Too fast, Not enough torque" side of the motor spectrum.

 

[jordanator62]

not really, brushless have a lot of torque if geared down, and also have that high end you need for some wheel spin and MUD BOGGIN!

What BL system are you gonna use??? Its gonna have to be senored cause a senorless with just sit there a "cogg" when you try to go up somthing... just my 2 cents

and NICE axles man...


Later
Jake

 

[EGRESSor]

yes its a sensored Schulze mcd controller and Plettenberg HP300/20/A4 , a low rpm motor , 740 rpm/V@20amps and 1.6in-oz/amp
calculated speed 7-8mph@6cells

and Jake , pm me if you need a 12t M1 pinion

EGRESSor:

Get a shot straight on from the side with the suspension at ride height, and not flexed. For a shafty, its a good idea to have your uppers and lowers at least the same height, or have your uppers longer even. Its also good to try to have your uppers flat.

Nice work on your axles.
It looks like you have a TIG.
What brand?

 

[EGRESSor]

articulation 55 degree per axle
wheelbase 390mm
width 410mm

and Jim , i use 2 units
a Fronius magic wave 2000 ac/dc TIG
and a Fronius TIME synergic MIG/MAG/MIGbrazing/TIGdc

 

[SR5Dave]

Damn thats wide! What is the wheelbase now? It looks way short for what it is.

You might want to try to raise the axle end of your uppers some, that will flatten them out also, since it looks plenty low.

 

[EGRESSor]

oh
i´ve edited the wheelbase in my post at the same time

 

[SR5Dave]

I think a 425mm wheelbase is ideal... Your wheelbase now is way too short for how big that thing is! It'll be wider than long :lol:

Also, 55* of flex per axle is nearlyt twice what you want Aim for like 30 maybe 35* per axle.

 

[EGRESSor]

i think i can go to 420mm wheelbase without new links
and the shocks will limit the flex to 35* per axle or 40

if the shafts making problems , i will build some Clod style steel axles

Looks like some 1:8 scale buggy parts in there! Sweet job, good idea on the tranny too.

 

[skyjacker_rc_club]

Nice idea on the tranny that should fix any torque twist problems. :idea:
