One Klutz to Another
I can relate to your driving experiences.
Here's what I learned:
Just like golf - don't grip the wheel too tight
Get a faster servo - the best you can affort - It makes up for your slow responses
Adjust trim to about 60% of servo travel - usually have too much travel
Slow down, stay out of the throttle
Hang back at the start - let the pack go - 50% will crash in first lap
Focus on a lap without touching the boards or rails.
I really suck - but it's gotten better with some discipline.
Money buys speed - it doesn't buy good driving.
