Toe Brake effectiveness. Increase/decrease?

[Fozzer]

Hello Chums.... ...!

On some of my little Microlights, the toe brakes are either not fitted, or are not effective enough for my liking.

I have added this typical entry to the aircraft.cfg file (if it was missing).

****************************
[brakes]
parking_brake = 1               //Parking brake available
toe_brakes_scale = 0.68    //Brake scalar//  I'd try it in  0.02  increments.
differential_braking_scale = 1.0  // rudder activated differential brakes
****************************

Can anyone advise me of the numbers which have to be applied/changed to increase (or decrease) the toe brake effectiveness.... ...!

Many thanks.... ...!

Paul...Give me a break!..... ...!

I tried increasing the Brake scalar number to 1.85, but it made no difference!
It seems that if the original model was not designed to have brakes then they cannot be modified by the user... ...!

Check the 'Brake Map' for each wheel in the [contact_points] section.

Check the 'Brake Map' for each wheel in the [contact_points] section.

The brakes are not defined Paul, Change it like this.

[contact_points]
point.0 = 1.000, -12.000, 0.000, -1.90, 1500.000, 0.000, 0.500, 22.000, 0.250, 2.500, 0.700, 0.000, 0.000, 0.000, 0.000, 0.000

point.2 = 1.000, 2.000,

PS. point.0 is usually either nose or tailwheel which doesn't have a brake fitted.

Whey-up Doug.... ...!

Many thanks.....Sorted...stops on a postage stamp now!.... [smiley=2vrolijk_08.gif]...!

Thanks to Doug and Dave.

I was previously running out of grass runway and ending up in the hedge, after dragging my feet on the ground.....arse!... ...!

LOL... ...!

Paul....Heart break... 8-)...!

[BAW0343]

The fun of FS breaks  ;D  When I made my supersonic C172 it was powerful it could takeoff from idle, I had to increase the brakes by 50  :D

Glad you sorted it all out Fozz!

Hello BAW...!

I wouldn't have thought you would have had any problems with hanging on to the reins in your supercharged '172, when buried up to it's axles in Arizona sand... ....?

LOL.... ...!

Cheers BAW.....!

Paul....Spring Break.... 8-)....!
