Strap-on Video, take 3

This shiny new LOC Expediter rocket is prepared for induction into the Telstar Logistics fleet. It has been heavily reinforced to take the anxiety of huge motors and a strap-on video camera to catch the launch action.

For instance, I Kevlar-wrapped the physique tubes (the reduction coupler shows it unpainted) and fiberglassed the fins, tip-to-tip. The battery connections are soldered. I utilised a custom motor tube than runs up by way of the yellow coupler

To streamline the videocam cylinder, I glued half of a plastic Easter egg on leading and fiberglassed the seam.

And the laser-cut vinyl flames come from GraphixnStuff. I met Dave at BALLS and was delighted to see a website devoted to rocket decoration!

This will be my third camera to try to survive the g-loads of launch and the mishaps of reentry. The 1st a single shredded on a V2 + K700 motor. Here is a “successful” Norad flight photo and video from camera #2 on an H210 motor (the subsequent launch became a ballistic lawn-dart into the Black Rock Desert). This Expediter kit is a scaled up version of that earlier Norad rocket, and I will attempt successively larger motors to test its limits (J350, K550, L730… see ya! That last motor would certainly eliminate the camera as RockSim shows it screaming via Mach1… need a strategy for that =)

Cutting Perspex

Support the material reduce with wood supports, Set the material and blade to reduce toward the backing.

For thin material spot the wooden backing so that the blade really cuts into the backing slighly. Use quite slow cutting speeds.

Cutting perspex or most plastic sort material needs to be completed with really slow cutter speeds.
Cut as well fast and the material will melt! jam! and often break the cutter.
