I noticed the front and rear shocks are angled differently, is it an issue?

A better explanation ...
It's not really an issue with the chassis its an issue with how I like things (driving style an such ) I prefer the rear to be more up and down and straight
And I like the front leaned a little softer and more flexible
And leaned in instead of straight up and down
I feel this gives you a stable rear and a flexible front that's able to feel and grab
But .... I could be wrong all together

Couple small updates
Rowdy racing battery mount
And I changed up the front weight a little
Wanted to go with just full on knuckle weights no wheel weight but the losi wheels wouldn't let me
So I ended up with 2oz knuckle weight and 1.5oz in the wheel
Wanted to try just a lil more weight up front
Other than that I gotta tidy up the wiring and bend the front of the skid up
Taking her out for the first official comp tomorrow

I have very limited experience in crawling so far but, with out changing too much I've been changing things one at a time in a experimental fashion to learn what parts are responsible for certain parts of movement, and one of the things I have discovered about the suspension is that with the front shocks laid out (closer to parallel to the ground) the softer they "act"

yes exactly but go to far and they pretty much stop working

It's called leverage, if you take the two extremes, vertical and horizontal, moving the axle with the vertical shock would have the most resistance to compressing the spring, whereas the horizontal shock offers no resistance to moving tha axle

The S.P. looks a bit tippy at the moment, have you tried different link positions, from the camera angle it's hard to see

If you look at this project by markfw, the link geometry just looks right to me, and they say if it looks right it usually is pretty close:





The top links are almost in a straight line but slightly higher at the front

in order for me to run my rear upper in that position id have to find something for lowers
i'll look around

Yeah it has no problem with just about any breakover

I did run one course last night
10 gates for a -9 and that's pretty good for my driving

Based on those pics above I can see where my links need to be but I'm not sure I have the materials to get it done...
