Most likely it was just anodized for too long, so thread was weakened.


For those interested in adapters:
Sorry guys, I was on bussines trip last 2 weeks, I will start sorting this out as soon as possible.

I've had the f109 for 1 month now.its my first f1 and I love it. I am facing one problem though.
I can't get any stable braking. Whenever I try to brake the car always spins.
I have no problem with traction (12.5t brushless), no problem in corner speed.
At the moment all I do is lift the throttle early enough for the car to slow on its own.

I have tried loosening the back with softer springs, looser diff. I be also tried every setting on esc and transmitter.

Any advice on what I should try to change?

PS: I am running rubber. Shimuzu soft at the back and medium in front.

Any 2wd car with rubber will become unstable at braking.

I have only 25% of brake in my xerun rigth now.
Try the least ammount of brake you can. Motor is sensorless or sensored?
Sensored brakes better

tigerdim

Ok thanks. I was trying to reduce the braking until
I couldn't block the wheels but once I got under 50% I started to think something was wrong. I will just have to do like that.

2WD will spin even with foams when braking hard. Try 20~40% of drag brake set on your speedo at neutral, that helps a lot.

I'm getting ready to order the parts to do the crc mod. I also wanna get a set of front springs, which ones should I get? Do the crc front springs fit?

EDIT: Also, anyone know of any upgraded turnbuckles for the front end (camber link)? Isee there are titanium turnbuckles for the steering and pod links, but I didn't see any of the small ones.

For setup wise, the tires plays the most important role.
I just acquired a F109 recently too.
Had my first race on asphalt after 10 min of "virgin" run + setup session.
It handles like a dream, pretty similar to my 1/12
You may want to try out the below setting as a guide -

Front -
front spring:AE 0.20
Camber:1.5 Negative
Toe: 0.5 Positive
Droop: 0.5mm
*use tamiya carbon uprights + alu servo saver (original material is crap), file down 1mm or more to achieve desired ride height for rubber tires. Longer kingpin to remove preload on the front spring.

Rear -
Shock Oil: 20Wt for Rear, 20Wt for link
Spring: Tamiya "Hard"
Diff: 3racing out tuned + F104 carbon shaft and clamp-type wheel stopper.
Side spring: "CRC mod" with AE Silver (all hardware using AE)
Batt position: All the way to front. mod using 12R5 batt retainer to prevent the batt from hitting the center support. (need to drill a hole on the chassis for the retainer)
Droop: 1mm negative

Tires: Cold weather: Med front, Soft Rear (Shimazu tire)
Hot Weather: Hard Front, Med Rear (Shimazu tire)

I did other numerous small modification or changes on the car for durability issue.....

Have fun running!

Bad news for those interested in adapters for GT wheels, guy who did the inner hex for me no longer works in that company

Maybe THIS can be substitution, but I dont know these adapters personally, so no refference.

Anyone?

You need the side springs set and spring retainers.

Stregone

JR007
