Stupid Question: End Points

[simoncrabb]

Okay, I've been doing this RC lark for a million years, but i've only ever set my 100% end points to be the point where maximum lock possible is.

Then I set the car up to work with that amount of steering.

Could I be doing it a different way - ie less lock, but an equivalent amount of turn-in?

It's very unlikely that the EPA will be 100% in any car, ever.

First, set the dual-rate to 100%. Then, set the EPA so that the steering reaches full lock, no more, no less, without straining the servo. Obviously the steering linkages will already have been set up evenly, and the servo sub-trim will be used to set the servo neutral position.

You can now use the dual rate control to decrease steering lock if the track requires it. I generally start with enough lock to turn full circle in the narrowest normal section of the track, would rarely go more than 10% different from that.

To change the feel of the car on small stick movements, use the exponential - NOT the dual rate. Again, only 10% adjustment should be needed - more than that and you start to mask the cars handling problems and end up with controls that are far from linear.

Simon, I presume you have checked the turning circles are the same left and right too?

If I make it down to TORCH on Sunday remind me and I'll try and run through it with you.

its not a 12th scale kieth!!!!!!!

[KRob]

Yeah, theses are just toys, not proper racing!
Maybe if you'd checked your turning circles you wouldn't have been so useless with a 12th...

hey! 1 12th race 1 win...thats 100% unbeaten in the last 5 years!!
