On-Board model rocket video--dual "E" engine cluster!!

This is a scratch built Sidewinder style model rocket flying on a pair of Estes "E" motors. The flight is quite exciting and at one point, incredibly realistic looking!

How'd you get 2 engines to ignite at once? I tried this so many times but my igniter wouldn't allow me to. I even tried using a Car battery and still it didn't ignite :(

@TheApana I made a parallel adapter (Simple Y harness) and used a car battery with the normal Estes ignitors. I have another rocket (triple cluster) and this method works perfect for it also.

The "weathervaning" was because your rocket was over stable. This is because your center of pressure and center of gravity were way off. I suggest downloading the free version of RockSim. You just put your rocket design in and it finds the cp and cg and you can adjust parts such. I use this because i don't have the money to keep buying E engines. I design and run a simulation flight and I fix what needs to be fixed then i build my rocket. It's much cheaper than wasting engines and having to was

not long after launching it, I actually loaded it up to openrocket sim. I did find out it was over stable. I never had a chance to fix it because on its third launch, it landed in a bunch of trees. :( I have a good idea of where it is, but still can't locate it. It sure was fun to watch it fly though!

What kind of camera were you using?

[ABbuggin]

@aviationmanSam Just a key chain camera that I bought off of ebay

@CanItBeDone11 No it was because he had GIGANTIC fins up front so it tries to behave more like an airplane than a rocket hence why it did not weathervane it LOOPED 360" + and then damned near glided down sans chute. (common problem with "sidewinder" style missiles. they are intended to be damned near unstable to make them damned hard to evade :-) ie they can turn tighter than you can usually :-)

Cut down the size of those fins up top or increase the size of the lower ones to reduce this.

Well, Thats what men says Overstable
