/// riocrokite: ballute material
MATERIAL
{
	name = Zylon
	description = Much stronger and resistant to heat than Kevlar however prone to sunlight radiation thus for one time use.
	areaDensity = 0.0002278  // 70% heavier than nylon and x2 to account for toroidal shape
	dragCoefficient = 0.20 // to account for ballute shape compared to parachute
	areaCost = 0.24 // hard to get and expensive
	maxTemp = 1600   // decrease it if you feel it's too op
	specificHeat = 25600 // so it doesn't heat like crazy
	emissivity = 3 // good dispersion of heat
}



----------------------------------------------------------
Sample config for Ballute250.cfg. Delete everything with '//' (ModuleParachute and ModuleDragModifier) and add RealChuteModule.
For other ballutes just change preDeployedDiameter and deployedDiameter values to those from commented section of ModuleParachute.
