This is a good question for Oleg.
I rarely ran straight pins on the Tamiya, TOP and Xray cars with a spool. Always felt like the car initiated better with some arm sweep in the car. I am trying to visualize the difference between the pivot vs. hinge pin caster blocks and can't rationalize what the difference would be.
Something to also consider is that Xray made really good use of arm sweep in the FK series of their cars. There was a totally different feel you could get out of a car with outboard rear toe vs inboard rear toe. Their cars always cornered well under power with the outboard toe.
I don't have the car in front of me but I would think we have straight pins and are effectively dialing in outboard toe.
Lets hear what the experts say...

Agree with you Mark about rear toe, I think outboard is one of the main reasons for the A700's handling characteristics.

Well I'm no expert but it was the first thing I asked Oleg when I got the car, there is no sweep, and probably quite tricky to incorporate into the current design.

I thought those holes were a legacy from a previous prototype with shorter wishbones, surely the distance between those holes would create too big an angle of arm sweep?

Code:
r = 44mm (distance between arm mount locations) length of circular arc = degrees * (PI/180) * r 1 degree -------- 1 * (3.141/180) * 44 = .7679mm 2 degrees --------- 2 * (3.141/180) * 44 = 1.535mm

Hi all,
I've been wondering whether arm sweep would be beneficial on the A700. I haven't measured whether the A700 has arm sweep built into the chassis for the front arm mounts, BTW. I'm also wondering whether it's even appropriate given the swivel nature of the way uprights mount to the arm.
Does anyone have thoughts on that subject in respect to the A700, description?
Thanks,
Ethan

You have very easy possibility to check the influence of the upper arms sweep on A700. It does not require any additional parts and part's reworking.

We'll check the effect of the inner sweep of the lower arm, though, I believe it will be much less noticeable than for conventional suspension due to lack of outer hinge pins in our suspension.

I think I checked this before, but the lower arm interfers with the damper if you try to run sweep, and you basically can't get the arm into the mounting hole... It'd be a lot of sweep too!!
Now upper arm sweep sounds like something interesting to try *adds to test list*

Is the long upper arm set just AT-25 x 8 plus 2 x AM-18
