Estes QCC Explorer Build
This is my first build in a few years. I found the QCC Explorer model very appealing, with it’s retro-futuristic look. It’s not too hard a build, although it’s a Skill Level 4 kit, probably for the complex engine intakes.
The balsa sheet was straight and very well cut. The fins were a little warped.
Motor Mount
I decided to install a replaceable shock cord, fed from the front of the motor tube and tied around the motor tube in the back

Lasso the motor tube with the Kevlar cord. The only way I see to reach it is by making the exhaust nozzle removable.
