After getting a ton of input, here is an updated Handling Issue list
Thanks to everyone!!!
#5448 handling issue - technique stuff:1. minimize amplitude of course corrections, "it WLL come back"
2. Keep a light touch on steering wheel, gentle, smooth course corrections,
3. Both hands on the steering wheel equally, be careful during shifting & parachute deployment
- "SS: parachutes need to be actuated without removing hands from the wheel"
4. Any movement of the eye can be translated into movement of the hands...
5. Feedback: ask an experienced TFA-sized guy make a pass in the car (Tom? Rex? Stainless?)
6. other??
#5448 handling issue - set up stuff: 1. Would adding 300# F ballast help stability? (gives 55/45%) Pros & cons
2. Re-determine our Cg-Cp relationship, document basic vehicle info
3. Re-check L-R tire psi are equal; is F-R psi a factor?
4. Further minimize play in steering linkage,
- look at the steering reverser box, get gears tighter, replace?
- ?replace Heim joints (tie rod ends) w/something better?
- ?replace linkage universal joints w/higher quality?
5. re-measure scrub radius, how close to zero?, find a way to measure it more accurately
6. Other?
7. Put car on automotive alignment system:
- measure castor; lots of caster is always good to go straight (not adjustable)
- measure front toe in; set to ?1/8?", is it better to err on the side of more or less toe in?
- review toe-in vs toe-out
- check the rear axle for being perfectly perpendicular to the car's centerline
- check the toe in in the rear, assure it is equal on both sides and not all on one side
- other?
8. assure both F tires are same diameter, add pressure to the smaller on to equalize (as feasible)
9. assure L&R( F?) tires are at same psi in starting line, sun impact (up to 15psi difference)
10. R tires, assure same circumference, use pressure to equalize as feasible, watch sun effect
11. put laser on car F-B, assure body is straight
12. add steering stabilizer?
13. load/ballast one side of the front more than the other?
14. tq steering from unequal length F axles? (or something like that)
15. check toe-in setting stability under accel stress?
16. re-scale wet car w/suited driver to assure F L&R wheels are equal wt +/-?10?#, also document F/R wt distribution
17. slow steering rate down?
