Amount of Recovery Wadding?

[EngineSniffer]

My first 2 HP rockets were PML kits so I didn't need to use recovery wadding as they have the piston system. The kit I'm working on now is a LOC/Precision and wadding will be necessary.

Is there a rule of thumb regarding how much wadding to use? I've read that 1 body diameter will do it, but is that really enough??

Thanks!

I'm assuming you're using dog barf?

I'll admit, I kinda eyeball it -- I add enough until I'm comfortable that the parachute is protected. It's cheap, it's biodegradable, it's hard to use too much unless you get excessive.

Get a Nomex or Kevlar Blanket/Chute protector and never worry about wadding again.
See Giant Leap Recovery page, Quickburst recovery prodects and Wildman Rocketry.
Or You can get really anal about the whole thing and use Dog Barf (cellulose insulation) and a Chute protector.
