Estes Tandem-X review/build/launch Part 3 of 3 - Crossfire ISX rocket 

Logan Mason so true I could have never figured it out without this vid

Logan Mason try using the chinese instructions - much clearer.

Primus20 Transf

Im glad this helped you but i didnt seem to have much trouble with the instructions but i might have more experience

@@jaydenpayton4360 yessir. Transformers all the way

Seriously!!! You are one rockin mum!!!

NJA 3 i used a carving knife lol but it worked

Additional mass has no effect on the rate that an object falls back to Earth. The localized acceleration of Gravity is a constant. x = v(initial) t + (1/2) *g* t^2 Since v(initial) is zero at apogee then we can write x = (1/2) *g* t^2 Solving for t... t = SQRT(2x/ *g* ) where x is the height at apogee, *g* is the acceleration of gravity, and t is the time that it takes to travel. (Mass is not a factor in that equation. Weight, W = m *g* ) And at constant velocity, as when descending suspended under a parachute, there are ZERO unbalanced Forces acting upon you. *F* = *W* = m *g* = 0 (Although mass is a factor in that equation since the product is ZERO then the Mass has no effect. in fact you are essentially experiencing weightlessness during that condition. Free Fall...terminal velocity.) Drop a ten pound weight and a one pound weight at the same time from the top of a ladder so that they fall an equal distance and then tell me which one strikes the ground first. (They hit the ground at the same instant.) Weight has nothing to do with it.

24kGoldenRocket drop a ten pound weight and a feather and see which one hits first einstein.

@@24kGoldenRocket Consider the affect a parachute has on decent. The rocket is not descending in a vacuum. The parachute is creating drag due to the atmospheric gases. Put the same size parachute (e.g., 12 inches) on a penny and on a ton of lead. Which will descend faster when apogee is 1000 feet?

I'm using a B4-2

I used a C6_5

how did it go

what kind of rocket is that, whats a good rocket to use and where to get it. I have some experiments i want to do.

good to know. I think I'll mess with the parachute to drop it faster or maybe install a streamer would be a good mod

+William Tomlinson Glad I could help.

Thanks, I don't plan on stopping. In fact I've just started one on the Estes Hi-Flyer. After that I think I'll do a skill level 2 rocket.

Spray paint. Prime, sand, prime, sand, prime until smooth enough, final paint(3 light layers). Just one of many methods. When I was a kid, I would apply Testors model paint with a brush and it looked bad but worked fine.

G L I don’t think you need to but I’m not 100% sure. I never do the tape

It’s to keep rocket from resting fins on launch plate. Some launch pads already have a standoff, if yours does not then yes use the tape.

I'll look into that. Would be a nice kit to try.

I haven't done it myself, but I can tell you that it isn't cheap. A good resource full of experts(and noobs) is rocketryforum.com. Everything you might need to know across all skill levels is on that site.

Most likely the cause is wire leads touching right where it bends, causing a short. Also make sure you're holding both the safety pin as well as the launch button for a good 10 sec. Check if you have new batteries.

You mean the coupler on the Amazon rocket? It won't matter. The grate thing is only there to keep the wadding and chute from falling down too far I suppose. Both my Amazon and Crossfire have flown great several times. C6-3s are perfect for the Amazon.

@@Malikot3 yes I was asking about Amazon coupler I did it same as you now I'm debating about where to tie parachute to shock cord or cone? I want to launch them both sunday,also I'm doing c6-5 in amazon and c6-7 in crossfire I hope it goes well idk this my first rockets and first launch ever.thx very much for fast reply

I have better luck tied to nose cone. The chute gets out right away, less chance of it sticking at the end of the tube. Apogee has a great video of rocket prep for first flight. I highly recommend that channel as well

Also, the c6-5 in the Amazon should be fine. The chute may pop late but as long as it went up straight in low wind, you should be ok. The Crossfire with a C6 is gonna scream! Have a big field and watch it closely. Good luck!

@@Malikot3 I haven't even launched yet and I'm looking at my next build estes hyper bat 2stage,I find myself only looking for highest altitude rockets.i can't thank u enough for the knowledgeable replies an also video builds I greatly appreciate you for these.

Coffee stir sticks, BBQ skewers, etc. are all handy and cheap.

Hey, cool! Never thought I would reach 500. Maybe I should get going on some videos I have planned

The yellow tube is a tool for placing the ring at the right depth. It is the same size as an engine.

I dont remember seeing a long clear decal. Im sure youll be fine. I just looked at the box and tried to match how it looked in the picture. Many people paint it however they like. Sometimes I fly rockets with no paint at first. Once retrieved, they've 'earned' their paint...

On your forehead

The difference is total impulse. An A is 2.5Ns, a B is 5, and a C is 10. In a nutshell, a C should make it go twice as high as a B, a D twice that of a C...

Coffee stir stick. Dollar store I think it was.

+kreeetin "Spill holes" are common and are occasionally used by NASA. Some chute shapes may not need them but the technique is used from the smallest to the largest.

I usually cut them about the size of a quarter.

@ kreeetin "Never cut the hole in the center of the parachute" ????? Cutting a Spill Hole is totally ACCEPTABLE and often used. I've done this to several of my chutes in my fleet over the years and had no problems !!!

Yup, I noticed. Very cool. I watched along for a while and tried to help him out a bit in the chat. Hard for him to build a rocket and live stream at the same time.

@@Malikot3 wew,

Aussie Dan mine too

Like camera

Ahh.. ok got it. Kind of a small space I have to work with but I'll see what I can do. For now, it's the "standing next to me" angle.
