Starts for my birthday.

Stinger worked only one of the light launch pad. When it started, it fell and the stinger went on the ground.

2 " shells 56 grams of weight worked out regularly (the stars are all old)

3 " with a weight of 170 grams (one shell crushed the old stars)

4 " mass of 460 grams worked well, only flew away very much (above was 6.5% of the mass of the ball)

No thanks, it is more the construction, assembly and fusing of the 7 tubes together...

You can turn on auto-translate for the subtitles... But be warned, they require a lot of mental power to translate the translated English into something that makes sense... Also, it is good for a laugh if you do not need the words themselves.
