This week we've been repairing the damage to the G2 rocket. Last night I finished the G2 backup parachute system. The fairing is new as is the coreflute framework. I straightened all the bent pins on the electronics and resoldered all the severed wires and fitted new connectors. I also replaced the 3 Lipo batteries. All the electronics are the same from the original rocket including the servo motor. Despite being scattered in a wide area in the explosion, it's surprising that all the important bits survived. That's around $200 worth of electronics. I'm still waiting for the camera and micro SD cards to be delivered hopefully this week.

Repaired Backup parachute system with altimeter.  

 The main deployment mechanism is also pretty much repaired and only needing a new coat of paint. There was only minor fiberglass damage to the body.

Damaging the medium launcher in the explosion is giving us the opportunity to redesign the launcher. The new launcher is going to be a single rail design and the rocket will use buttons to attach to the rail. The main driving principle for this launcher is quick setup and portability. The medium launcher although very versatile was taking around 10 minutes to set up and 10 minutes to take down. The new launcher should be about 2 minutes.

Hey George,

Looking good so far, :) and thats a lucky save with the electronics, :)

Hopefully (fingers crossed) 3rd time lucky for you with G2. :)

Looking forward to seeing the new launcher and hopefully a launch.
