guys READ EVERYTHING AGAIN and watch carefully.
This are three(!!) different planes with the same design.
First one is at the VIDEO with a Behotec J66 engine with 75N thrust and the max speed is 395 km/h (246mph). It has a long black canopy. Take off weight is 11lbs. This one flew at the AMT- Jet-Meeting at Porz/Germany with 33° celsius outside air temperatur with approx. 370 km/h. 395km/h was meassured at 6°celsius. I´ve seen Bennys Pulse Jet. 420 is for sure but a loud plane always seem to be faster than a quite turbine plane.
Second plane has a Behotec J66HP engine with 85N thrust. The clamps are just turned around now!! This plane showed at the first meassured flight 455km/h. It is the one a this Homepage: http://lim0707.bei.t-online.de/niels.html
Max speed was 481 km/h(299mph). Take off weight is 11.4lbs
The third one is powered by a Behotec JB130 engine with 140N !!
and has a take off weight off 14lbs. It is at this homepage: www.hessenbruch.de/niels and it is the fastes with 576km/h(358mph)
Look at the colours. I think pink and green are the best colours for flying far away.
Hope it makes everything more clear.

Sorry Niels, but since I was more interested in watching the vids, I never paid much attention to very slight differences in the models. Especially when all three (?) are painted
EXACTLY alike. You have to admit, very few people paint multiple models exactly the same. I figured you just had a 5 gallon bucket each of pink and green and were trying to get rid of it!
The only difference I noted was that a couple of pictures show a cowled engine. Knowing that you changed power plants, I didn't dig further looking for even more differences.
BTW, again, I'm just interested in how you got to 350 mph. Nothing more.
