I'm getting my 4" Loc iv ready for dual deploy, and added some weight in the process. after adding everything up the total weight without motor is 1984g. i have a 50" chute i got from the LOC black friday sale i was planning on using as the main, and the calculator i used "decentratecalculator.net" says it will slow it to around 20ft/s assuming main is around 350ft. that seem a little fast. It says it would recommend a ~60inch parachute. looking for any rule of thumb on this topic, are these calculators online useful or should i follow my own calculations? is 15fps the ideal landing speed or do you think im able to wiggle it with 20fps?
thanks!!
thanks!!
