I'm trying to figure out how to include my electronics telemetry payload in my rocket design within OpenRocket. I'm expecting the electronics to be around 500g but I'd like to somehow incorporate a hatch-accessed bay. Currently, my set up includes (in order from top to bottom): nose cone, recovery bay, and the main body tube. I had planned on using a bulkhead to divide the body tube into two sections so I can use the upper section as an electronics bay.
Has anyone done this before? How would the hatch-accessed bay affect the weight of my rocket?
I've also provided a picture of the rocket in OpenRocket so you can get an idea of what I'm looking at.
Thanks in advance for any help given.
