1/14 Recoil!!

With all on and off-road cars that have the wheelbase adjustment in the rear (abillity to move the rear wheels a bit fore and aft), moving the wheels forward reduces steering and increases rear traction in general.
When the option is in the front-end, shortenening the wheelbase ALSO moves the weight bias forward. This has a more significant effect and increases steering a great deal.

Doh' i knew that lol

have aby of you determined how to true the tires down? if so how do you do it?

[straightspeed]

Has anyone fitted an Anti Roll (Swaybar) bar to the Recoil? I cant find one as an option from Sportwerks or Carisma, do any others fit?

[chicagokenji]

Is there a need for a sway bar? All my tires stay planted all the time on carpet and asphalt.

If your wheels are lifting thru turns maybe your shocks need to be rebuilt?

[straightspeed]

I have too much rear end grip, causing grip roll. I'm looking at alternative ways of curing it.

[chicagokenji]

You might already know about these and have tried them already but if not:

use CA or nail polish on all the edges of all of your tires

try a different shore rating of tire

in the rear make the shocks stand up higher by moving the links to the outside holes on the tower

check your camber settings and adjust

Are you using traction compound?

I'm sure you know to do one change at a time then drop the car down and try it before trying another.

Usually grip roll is caused by too much traction in the front.

I'd followed Chicagokenji's steps at solving your problem.

Sorry I'm looking also. Need to get someone to make an arbor

[straightspeed]

Thanks. I'm running on rubber, and CA has already been placed round the tyre wall. No traction compound - not needed

So far I've played with roll centres, front and rear, and shock angles at the rear only. I may try standing up the front shocks for next week. Ride height is as low as I can run it, and I'm limited on spring rates. Camber is at 1.5 degrees at the rear, and .5 at the front. I'm sure the poor quality of the stock shocks is contributing, perhaps the Alloy ones will help.

I found foams to help with the grip roll. The insert for the rubber tires are too soft and the side wall rolls under.

Springs can be made with 12th scale rear/center shock springs. I just cut one into two.

This might not work for you since I read you guys are required to run stock or recoil hop-ups.

More expense A few of us are now running foams, and they dont seem to have as much grip roll. Time to join them.

I was also running a very heavy ESC - LRP 7.1 - as it was the best of my spare ESC's from a performance point of view. I've bitten the bullit and replaced it with an MRT MX. It did seem to be worse when this was fitted.

You want everything as down low as you can get especially a big esc

[straightspeed]

Everything accept the Spektrum reciever is mounted on the chassis. I've removed the lexan battery tray so the cells sit as low as they can get.

[Sydewynder]

I thought where you're running all you guys were required to use a stock or recoil only hop-up cars?

[straightspeed]

There's rules, and there's rules

2 Class's.

Stock, using no modifications although you can replace the transmitter for a "cheap" 27mhz Stick Radio.

Modified, using Sportwerks Hop Ups only, but radio gear is completely free.

I went mod, just so I could use my regular transmitter.
