Just aquired a F109.
Looking for setup to help me set it up, as i am new to the F1 game
any help would be great
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 spring:AE 0.20
Toe: 0.5 Positive
*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.
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!
