	Update 9/18/2023: since that 48" Fruity Chute is now nominally being used for three rockets ([[Buster]], [[Kerbal 5]] and Black Widow) with a possible fourth on the horizon ([[Peregrine]]), I decided to order a second one. The old one is red/white, and the new one will be yellow/black. I'll rig the yellow & black one in Kerbal 5 for the fall launches.

	Update 9/9/2023: Yeah, I've let this sit for a while. I have a countdown app on my phone that helpfully tells me that there are 48 days left until Midwest Power, plus I might have an opportunity to do a shakedown flight at my local launch the weekend before. So I need to get going!		Update 9/9/2023: Yeah, I've let this sit for a while.
