Big Water Rocket with Boosters - Polaron G2

After several years of development and lots of procrastination we finally fly our full size Polaron G2 rocket with the big boosters at the recent "Thunda Down Under" international launch event.

That's so awesome! Wow! :)
It looks like a windy launch day but the results are still impressive.
Interesting to see how the sustainer rocket automatically corrected his flight direction after booster separation at the first flight ( 2:14).This is one of the best qualities a rocket can have.
Keep that awesomeness up. :)
Cheers

27 March is my birthday so this came like a present :)) because I have waited so much to see the Polaron G2 in flight and it is awesome :D
Well done guys !

Finally the full G2 rocket, It looks like a monster! Looks like the release mechanism does it job well. Keep up the good and professional work. If you launch this rocket with no wind it will go very high i guess. I followed you guys from the beginning to the end with this rocket and you guys keep improving. Cheers Basrockets

That's a great launch site. Finally Polaron is launched. AWESOME!!. The wind was indeed very disturbing considering the images. Perhaps by adding fins the rocket will be more stebalized ( boosters). The launcher seems to work perfectly. Great work. I'm looking forward to the upcoming launches.

i made a few calculations for the first flight. if it had stayed vertical, it would have gone 900-1026 feet. probably up to 1, 800 feet at maximum! that is a really cool rocket

Great to see you’re back. I always look forward to your next video. What a perfect place to launch a rocket! It was a little painful to see that your rocket didn’t go straight up. Nice onboard camera footage. I hope that next time the rocket will fly straight. I’m very curious how high it will go!

Felicitaciones por Polaron  G2, por fin ha volado!!
Me uno a todos los buenos comentarios que han hecho sobre este evento.
Quedo a la espera de nuevos logros que con seguridad van a obtener con este cohete. Un abrazo desde Uruguay :-)

Není co dodat. Moc pěkné a kamera na raketě má super kvalitu! :D

so nice process of the water rocket. vary good..you are all success full in your works..thank you...

[TechNiVoltisgrat]

It wasn't the wind that blow it sideways, it simply did a gravity turn

[ptx]

wow impressive! looking forward to see the next flights.

Enorme Cohete! Buen trabajo! Felicitaciones.

That's an impressive rocket and it's a shame that the weather didn't allow it to reach its full potential on that occasion. I'm already looking forward to its next flight. :) Cheers, b.

very cool GK, looking forward to seeing this go straight... i'm not saying it would be easy, but wondering if you have thought of a variable sized nozzle that could change size in flight to maintain the best performance.... like the nozzle on an F18 or similar fighter jet.

After months of waiting, the Polaron G2 with Boosters!! Certainly lived upto the expectations and I am looking forward to completely calm conditions for the long burn to have its full effect.By the way, for the boosters having a clean separation: Could you use little 'winglets' to help guide the booster away from the rocket when separated but keep them stable during vertical flight? I remember seeing a video you put out a few years ago with that concept. Keep up the good work! Cheers, Jamie B.

please post another video with this rocket soon :)

How would helium work as a propellant? How much pressure could you achieve with helium? Maybe it could be used in boosters.

Question: is the staging by its self? or do you press a button? thx

[andrewmackenzie]

Now you just need to make the engines gimbal to keep the rocket straight in windy conditions :)

That's impressive guys!
What's the theoretical maximum height that it could reach with a corrected vertical trajectory?
What kind of improvements are you going to take to achieve that result?
