Clustered Staged Model Rocket

nice!

[joe69rocket]

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.

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.

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

hey me again my rocket is all most complete and i was wondering if you could tell ma the diameter of a D engine.

[Calvertfilm]

24mm. That's the size required for the inside diameter of a motor mount too.

[rocketboy734]

Do you know what it is an cm.

[Calvertfilm]

Well I think you might mean centimeters. 1cm = 10mm (or millimeters). 2.54cm = 1 inch by the way. 100cm = 1 metre. This is the Metric system.

24mm is 2.4cm or just under an inch which would be 2.54cm.

Thanks!

YOU ARE MY IDOL!

[Calvertfilm]

I like your LineRider clip.

[Bob7k]

yay! someone has a 5stage D thay built, freakin insane. ive only got, erm, had a single stage C engine. i plan to make a multistage next.

[Calvertfilm]

Well here's a tip - I use something called 'Quickmatch' to ensure the stages ignite. It is explosive fuse material placed in between the motors. I got mine from HART rocket club in the UK, a club I founded but now run by a guy called Pete. Search 'HART rockets' if you are in the Uk too. Good luck with your rockets.

p.s. send me your links too once you've flown them.
