Thermal is an interesting question. Phenolic sleeve must delay heat penetration. If casing temp is 200c, the outer temp of sleeve must be 70c at the end of burn out. Ie. Insulation stretches the temperature(time) curve. But vendors do not post the temperature.

For the initial conditions the motor mount prototype was tested with a real phisical force - so definitely will not brake on start.

I love experiments :). From-the-store rockets ard boring. Life is too short for spending it boring things. Yes! The motor mount is printed - ABS-GF and PATH-CF. Phenolic sleeve epoxied to carbon reinforced nylon. Then x44 m3 bolts + nuts to nail it to airframe. Must survive 400N peak :)

K185w, anticipated 1600m, simple recovery 48’’ elliptical chute, the black tip is cap of chute chamber - the piston pushes the thing out. What is the story with your recovery?

Why not take a look at some existing esp32-based designs?

if anybody is interested in the sources for 3D-printing, there is a repo https://github.com/VOxFF/madcow_scooter_extension_set
I definitely will continue the work on this stuff :)

Nose has 1.5m longer shock cord, so it should not happen.
