As a rocketeer of over 25 years, watching your endeavours is entertaining.
Seeing you avoid what I would regularly use is also entertaining.
I use avionics to deploy my parachutes.
They work not on delay, like a timer, but on air pressure. Detecting a decrease and activating the ejection charge.
Can be installed in the nosecone to add weight to the rocket to move the CG forward.

You could launch the rocket from a larger model airplane, ignite the rockets and then land with the parachute.

You could have done a swing test to determine stability...
Right from NASA...
There is a relatively simple test that you can use on a model rocket to determine the stability. Tie a string around the body tube at the location of the center of gravity. (Be sure to have the parachute and the engine installed.) Then swing the rocket in a circle around you while holding the other end of the string. After a few revolutions, if the nose points in the direction of the rotation, the rocket is stable and the center of pressure is below the center of gravity. If the rocket wobbles, or the tail points in the direction of rotation, the rocket is unstable. You can increase the stability by lowering the center of pressure (increase the fin area) or by raising the center of gravity (add weight to the nose.)

The bit of you yelling "Eject! Eject!" with the rocket turning around and crash landing reminded me so much of the Top Gear Reliant Rocket episode.

"High velocity Golf hole puncher X15" - soon in a shop near you 🎉

@badaboehm

Brilliant stuff! The registration "66672" is quite interesting. It is the tail number of X-15-3 which broke apart during a test flight in 1967, killing pilot Mike Adams. Tail number 66670 is in the National Air and Space Museum, and 66671 is at the USAF museum in Dayton, Ohio. Both  museums are well worth a visit. Looking forward to seeing this model fly with a bigger engine!

@T3chpat

Finally! I've been looking forward to some more of your content. This will be a great Friday evening pleasure for me and my boy to gather and watch!
We get so much inspiration from your projects and daring adventures with RC crafts ❤

@DorsetSaferRoads

check what the world record for the fastest model aircraft is... clue... it doesnt have a jet engine, propeller or rocket... its powered by the wind and gets into the transonic regime.

@Ahahahhaaah

That was awesome! The scream it made when taking off was sweet.

@Poult100

The most amazing thing for me was the rotational stability! You must have somehow got those fins and wings spot on! 180°the whole way up is astonishing!

@barbeerian

I built the Estes model of the X15 back in the 80s before it was recalled for 'impact hazard'

@Walnut_thunder

Finally i was waiting for this the whole day

@cl00x3r

14:49 u nailed aerodynamics of it, look this stright line dive dart

@Bchorm2011

Loved the video part two please thank you for all you do for our entertainment.

@idahobob

Estes "BOMARC" missile model was a rocket plane, that would launch like a rocket then glide down.
The "trick" was an jestisonable tube that ran up the center. This contained the rocket motor as well as a nose weight. When the ejection charge fired, this whole center tube would slide out, nose weight and all, to parachute down. 
As the center tube left the plane, a small thread would be released to cause the elevator to go from neutral, to a slighy nose up, to help the plane to glide, rather than "Lawn-Dart".

shows hot gluing airframe

Now we know you're a true engineer! 😁

@SeanHodgins

I was kind of obsessed with the X-15 when I was a kid.

@rojopo65

That was an awesome flight.  It is amazing that it came in ballistic and still survived.  Nice job with the build.

@Alfimation

15:31 what a great soaring sound!

@chrislang7460

Glider... Dynamic soaring... Have a google man. Its up your alley
