What do you get when you mix an EPO Parkjet Mkll RC plane and an Estes rocket engine?
A rocket plane of course! 
We connected a normal Brushed ESC to the receiver providing 5 volts straight into the rocket engine egnition system.
The Flite Test crew tried to create a rocket plane awhile back, but the efforts were unsuccessful and the episodes never aired. Well, David decided he'd like to give it a shot and setup the EPO Parkjet with a D-Class Estes Rocket Engine!
The Estes D-Class rocket engine worked great! The thrust angle of the rocket was perfect and the plane launched and glided down better then we could have hoped!
The flight was such a success! So, it only made sense to try it again!... with larger class rocket! (or as David would call it, "huuuge rocket")
We mounted an Aerotech F50T-4 Rocket onto our EPO Parkjet , this rocket is 10x more powerful then the Estes D-class rocket. 
The airplane launched perfectly and then suddenly exploded the EPO foam plane in mid-flight sending components everywhere.
So all in all, it looks like the EPO Parkjet is a great D-Class Rocket Plane! But it's not a good F-Class rocket engine plane.
We'll have to revisit this experiment and see if we can launch a rocket plane from another RC plane in mid-air like a Bell X-1 style setup!
