Clustered Staged Model Rocket

LLOL Snr has 4 'D' motors, two staged and two clustered. This means it fires two sets of motors in pairs, which is quite tricky to accomplish. Easier really to have one big motor! But that is the challenge you see. Flown in 1997 by Laurie Calvert. www.calvertfilm.fsnet.co.uk

while one BIG motor may have performed as well... there is a certain fun and challenge in stages and clusters! good job!

[Calvertfilm]

Absolutely. Thanks.

So what ever happened to true multi-stage rockets where the stages would actually separate from the bottom. I had a three stager from Estes back in the day and by the time the third stage finally lit, it was pointing toward the ground...scary stuff. I was never really good with those. Now my Maxi Alpha was my favorite.That was a single stage D size rocket painted to factory example.

I designed these type of one-oiece rockets so I didn't have to recover lots of pieces of rocket afterwards.

Did that thing have a altimete on it and what altitude did it record for it peak altitude

[Calvertfilm]

It had no atitmeter on board as it wasn't going to go that high. I estimate 800-1000 ft only. It was more the challenge of doing it. Getting two to fire and then to set off another two is tricky. It took me 4 attempts! Really if I was going for performance just one big motor would have been easier.

nice!

5* no doubt

The para deployed in the normal way - the ejection charge from the two final D motors pressurised the body tube, and pushed the para out as it pushed off the nose cone.
