The gain wasn't provided by the castor angle being the same during suspension travel, but to the added stiffness of the C-Hub. It's like having a double wishbone suspension.
er... even with out torque rods, 415 and 414 already have double wishbone suspension.

Used torque rods back in 414M days, till I kept on breaking the knuckle or hub carrier on light impacts (2x4 wood barriers) finally said heck with them, no more breakage. With super stiff a-arms, nothing was giving out during impact. C-hubs are molded from flexier plastic then rest, so it would give a little with out breaking.

nope, this is not double wishbone, this is wishbone/upper link, which doesn't give the same kind of stiffness than real double wishbones.

Never had any breakages with the two rods on the 414M and I did have big crashes.

Now now stew, you should know about these... after all one of your sets is on there! hahaha

BTW there isn't a blank one for the std suspension on the page, however it is buried in the site, I've just yet to update the page... direct link here.
http://www.thard.co.uk/rc/TRF415/set...tup%20Sheet%20(std%20arms).jpg

Also, the LWT one i've literally just updated on the site, it's had a few font changes, and some of the numbering systems have been correct. minor changes, but brings them into line with the MS sheet. (same has been done with the Std suspension one)

Regards
Ed

technically... our cars don't have 'wishbone' suspension.. it's single A arm with upper control link. These cars use single arm for lower linkage, with hinge pin, not a single lower and upper pivot at c-hub point like 'true' wishbone suspension... To use the term 'wishbone' suspension loosely (like real cars, ie Honda) our cars would be 'double wishbone' Anything that's not strut based suspension can be loosely called double wishbone or double A arm. My old Honda and Audis had one upper control link, but they were still called 'double wishbone'

Only 'real' wishbone suspension in RC I can think of is T-maxx front end, and 1/8th scale gas pancar front end where you have 2 pillow balls holding up the c-hub.

Well, I ran my 415 for the first time last night and I must say I was disappointed and impressed all in the same evening. The car was wickedly loose through practice and the first 2 qualifiers (I only turned 10 laps in the 2nd heat because it was so loose and undriveable) but managed to get the car dialed in to qualify 3rd. I made a gamble on setup, motor, and gear for the main (hey, if you're gonna crash and burn might as well make it spectacular, right?) and managed to take the lead 2 minutes in and hold on for the win. This is only the 2nd time I have ever won the first night out with a car (the other was my F103). The one thing that I was curious about was on my other chassis when I have shortened the wheelbase by moving the rear arms forward, this has normally tightened the car up. On the 415 this actually freed the car up. Has anyone else found this to be true?

I didnt know why he did this mod, but Patrick had figured it out, and ran it today and loved it. Using 4mm of spacing under the ball nut raises the nut over the bellcranks, allowing a little further steering travel. It also came out to have nearly 0 bumpsteer like this, drive really well on outdoor asphault.

So in my view, there are only cons, which is running those links makes the car suck.

BTW, this was on asphault, dont know if its any different for carpet, but I do know I will never try it again.

Stock rubber. The top 2 qualifiers are towards the tops in points in out state series we have going on right now....one is the current point's leader and a top 5 finisher at the Novak race in Stock Rubber too. Just need the car to have some more low speed steering.

I played with the torque rods heaps when I had my 04r. You could never get full sus travel from full droop to level with lower deck without binding. Removing them improved the car in many was but best was that camber changes were very quick and hassle free.

Gary, I just got my 415 ready also. Haven't broken the virginity on the track yet, that comes later this week.
