two planes three flights

The first flight was done with the plane I was able to set the Guinness World Record with an average speed of 706,97 Km/h in September 2013. Absolut top speed with light tail wind was measured at the record event from the left side with 757 Km/h.
The second flight was a maiden flight with a slightly different engine.
The third flight was done with the same plane as in the second flight.
All planes:
Name: Trance
Wingspan: 1,04m
Length: 1,3m
Weight: 7,5 Kg at take off
Engine: Behotec JB 180 -thrust 180 N
Top Speed: 720Km/h or 447mph or 388Kt or M.58

Everytime i try to find it in the sky it ends up being dirt on my screen

Lol

Is this an FPV system I just can’t see how you would be able to control it otherwise and nice work

Wow. How many individual airframes of this design have you made in total? You mention two here - were there also many prototypes? What were the materials? Also thank you for providing measurements - I am a newbie and have not yet left the realm of polystyrene foam, but I would love to try and make (perhaps) a little basic EDF version of this one day. :)

These were two prototypes, two in these video (the first plane is the record plane), the one with the Mobius camera and one planed for a much smaller turbine which is going to be very light.
So a total of six planes. The shape of the airframe is always the same. But the materials are slightly different. I still test out different combinations.
The first prototype and the latest one with the small turbine have different colors schemes. But the planes with the Behotec JB 180 turbine have all the same color combination.
The materials are fiber glas, carbon fiber, aramid fiber, balsa wood , honey comb and airex ( a hard foam in layers, works as sandwich material).

I am not well informed about model aircraft so please forgive some primitive questions.
- How did you design the aeroplane shape?
- Is the aeroplane design done using a computer program (CAD)?
- How can you control the flight properly and safely when there must be times that you lose visual contact with the aeroplane and it is travelling at very high speeds.? I imagine you need to know at all times its instantaneous range (relative to you, the controller), its altitude (relative to the terrain) and its orientation (pitch, yaw and roll) relative to some axes.

Do you have plans for this plane? And what type of delta wing are you using?

[@TheGhostflier]

Since I have designed this plane I have the plans. Not commercially available.

Sir tatorial please how to creat this❤❤❤❤❤❤

You can't even see it what's the use in watching it
