DH108 Swallow first takeoff from launch rail system

This is the first launch of my 3D-printed 30mm EDF Swallow from clubmate Phil Bendeich's launch rail system.
Phil has been launching his Swallow using these rails for some time, using the model's own power to accelerate to take-off speed.
He recently fitted a very light bungee of linked rubber bands to the first section to give the model a helping hand to overcome friction and get moving, with the model's own power doing the major work.
The QX-30 fan seemed a bit down on power today, and the model sagged a bit after launch. Future mods will see a 4S Xfly 30mm fan fitted and a gyro reinstalled to smooth things out.
