Some interesting comments here. Not going to get into all the things wrong but, a curiosity question. If he had used a zero delay on the booster, might the additional g’s on the continued acceleration from the secondary engine ignition possibly shredded the upper stage? Guess I’ll never know… But I will say this, the delayed ejection charge on the booster engine would have allowed no chance for that to happen. Everything on this launch seemed to go right, would be curious to know what sort of maximum altitude could be achieved using this arrangement. BUT, just because nothing went wrong on this flight, doesn’t mean there couldn’t have been serious consequences in a launch like this. Murphy’s Law says when given the chance for something to go wrong it probably will. (especially with rockets) Always a potential Darwin Award winner with something like this…. And the proverbial “Who Knew” to follow….. It’s not Who Knew”, but more like, who bothered to think about potential consequences if something goes wrong. And that’s why laws are written and the government steps in to take away our toys….. Stepping down off the soapbox now…. Lol Decades ago I used to play with Estes rockets, loved those days, always single stages and biggest engines, D Series…. 💙😎
@@topcat43truffles15 everything did not go right. The delay on the 2nd stage ignition allowed the rocket to lose momentum tip and when it ignited it flew on a downward trajectory. You want the second stage to ignite while losing as little of the 1st stages momentum as possible.
Flying from your backyard, using a fuse instead of standard electrical launch controller and using a motor with a delay in the first stage rather than a zero delay booster motor.....lots of safety violations there. Very lucky that no on got hurt and that you didn't start a fire. (I've been involved with rocketry since the 1970s). Cool rocket but please read up on how to do this safely.
dcastle872...You are correct. However Brenton Boyd will not learn. His behavior is the epitome of the reason why I am restricted to only one launch site in San Diego County, California, with a altitude ceiling of 1500 feet. My flights must be during a club sanctioned event combined with FAA approval. Those events happen once or twice per month for three hours (The actual real time is one and a half hours due to club rules about recovery.) I just do not have the $1500 to donate to the San Diego County Courts as that is what the fine costs when one gers caught. People, like him, will destroy the hobby. I also have been flying safely since the 1970s and, even as a child, I have always followed the rules of flight. That Safety Code is engrained. He was flying a total F Impulse rocket *without a Level 1 certification.* (Two Es are an F) Furthermore he used 36.9 grams of propellant twice (Two E Engines) = 73.8 gms total weight of propellant. That is in direct violation of the 62.5 gm limit regulation set by our most wonderful and benevolent Federal Government...(SATIRE) So BATF might be interested. They only put me on the "No Fly List" when I ONLY protested the regulations on the NAR blog. I did not violate any law nor did I threaten to. So now I always have an Air Marshall accompany me on flights. And the strip searches are real fun. So I wonder what they will do to him for actually violating their arbitrary regulation....Of course I will not be those bastard's snitch. For what reason would I want to work for them when they have mistreated me? And then they think that they know it all. Perhaps there are reasons for that arbitrary rule after all. I shouldn't have embarrassed them online. Their retribution is not worth it. And as I have been shadow banned on YT recently I wonder if this will post.
Generally use an engine with no delay for the first engine, and only one with delay for the rocket. Also I could see that the rocket clearly was not straight, which meant that it was even more extreme
There should be NO delay on your booster engine. Booster engines, at the end of their run, the inside end as it is burning out ignites the primary engine, which has the delay and the charge to pop the parachute. Second, you never EVER light a model rocket engine with a torch, or use a fuse. You use an electric ignition system. An open flame should never be near the ground, anywhere, unless it is rocked off for a campfire. All the rocket accidents we had in California, which effectively banned the firing of rockets except in special places, and classified them as fireworks, was because people were lighting them with fire. Every one of them.
Thought people where just whining untill i saw the second stage start... With the rocket pointed at the ground. Yeah that's a tad bit dangerous... No different than a baseball going thru a window though lol except for fire hazard
Well, I know this comment is 7 years old, but essentially all you need to do is stack 2 motors on top of each-other, the bottom one being on with no delay charge (i.e. C6-0, E9-0.. etc) and the top one having a longer delay (i.e. C6-7, E9-12.. etc)
Why ya using a fuse to ignite it? That is against the model rocket safety code & not nearly as fun, safe, nor cool as using an electronic ignition system.....
Lol what happens when you get tired of asking permission to launch rockets on some dudes ranch or city park employee says oh you can’t launch on this beautiful big open field in downtown Orlando, Launch it on your own lawn in the neighborhood. Well just hope the parachute is successful or that thing is coming down hard on someone’s head with a lawsuit you have to deal with.
Not using the proper launch equipment, motor for 1st stage, or sufficient range for the altitude predicted. Don't do it like this if you are serious about the hobby.
