In this video I venture into my first minimum diameter high power rocket with a highly modified Madcow Tomach kit that will fly in Argonia, KS with a goal of 20,000 feet.

Too meticulous? I can't stand when people start rounding and guessing when it comes to rockets. This is rocket science. Even a small one needs to be treated as a large one. Kind of like treating every gun as if it's loaded. Great tutorial!
I appreciate the praise!
I'm not sure I'd go as far as to say every rocket should be treated as a large one. Obviously, they should be built safely, but there are definitely plenty of "corners to cut" so to speak on smaller stuff.
It's really just a balance of knowing what is and isn't required and, often, people overbuild small rockets to the moon!
9:09 The tack with ca, glue on the other two fins, then crack the first, sand and re-glue trick is GANGSTA! I know this comment is 2.5 years late but crazy Jim had a great idea.
neat project ! I'm yet to build my first FG kit but I heard that a mask is more than important when working with FG (especially sanding) cuz of the glass dust which go and make a big mess of your lungs. Keep it safe ;))
Yeah, typically I do wear a mask but you caught me slacking here
@@RocketVlogs ;))
Cynthia and I were going full-on Auntie when we saw him not wearing a mask. 😅
Late comment here, but what is your *fillet* epoxy of choice? I know from watching that you're a fan of West, (as am I, basically my entire L1 build was silica-thickened WS) but I know that a lot of people prefer rocketpoxy or aeropoxy for fillets. Your thoughts?
I glad to the see kit is being built. Going above 20,000 feet was the reason I bought the kit but as the saying goes, my plans changed. Yes, the fin glue guides came as part of the Madcow kit.
Thanks again for the deal! Hopefully it all holds together and I can crack that 20k mark.
@@RocketVlogs You're welcome. Have a good flight.
I've flown a 75mm MD to 25K on an AeroTech M775W Demo motor now the M685W with the fins tacked on with CA glue then fillets of US Composites Epoxy with Cab-O-Sil and chopped carbon with two layers of tip to tip carbon.
You used a racketball to smooth the fillets?!? Is that because of fin size, making bigger fillets or what?
It's a 3D printed shift knob that happened to be the perfect size for the massive fillets I wanted for the sake of span reduction and reduced fin flutter with fast flights
I mask off everything and just pour in some 30 minute. It levels right out without touching it and requires little manipulation. Am I doing it wrong?
Nope, that definitely works. However, for higher performance applications you may want to switch too a more robust epoxy
Is there any benefit to making the rocket longer than it needs to be? Assuming no issue with CG, wouldn't lower mass be better for higher altitude flights?
Length hinders performance! I'm cutting the tube down a bit more, too.
You should sim a K250W-P motor to see what kind of altitude you get. It has a burn time of about 9 seconds.
K250 was on the radar, but I just got off the phone with Wildman and I think I'm going to go with the K300, considering buying the Pro54 6XL case and the load is only about $30 more than the K250.
Flew a space cowboy on a k375 dual burn to just under 20000 feet would be great to get above that.
Fingers crossed!
You should consider building a mad cow frenzy massive
We're kinda out of room for massive kits as it is and I have an 8" V2 on the way.
Thank you for the video; feeding the algorithm.
You know it!
What do you look for in a quality kit? I'm looking at manufacturing some and wanting to get an idea of what's needed.
Good design and parts that fit are my criteria. Completion including recovery gear is always a plus.
@@RocketVlogs I couldn't agree more. We wanting to develop parts with a really good fit. Haven't had the best fit from some kits in the past so definitely things we will take into consideration when we start to manufacture our own.
Suggestion for your fin guides... Cut small notches at the tube/fin joint so you don't accidently glue it to the rocket (Don't ask how I know this).
I was a little concerned about this exact scenario, but in this case it cleared them pretty well thanks to the tape spacing
fin can in minimum diameter rockets rule m
What is the red/yellow rocket?
The big one?
@@RocketVlogs to your right

how do you cut a tube if you want to add a second stage?????
A chop saw with a new sharp blade will cut fiberglass tubes very cleanly, just cut slowly with minimum pressure. Do it outside though, the dust is a motherF'er, and blow your saw down afterwards.
Too much talk
Did you try not watching?
When will you be at Argonia?
September 3rd-6th
K'Tesh here... Who are you on TRF?
Upscaler
Can you share the epoxy you are using for joints? Thanks
Fin are tacked on with Bob Smith 5 minute epoxy and the fillets are West Systems with Colloidal Silica
@@RocketVlogs Thanks !
Man, you are not messing around with those chonky fillets!
@@TomLentz Gotta keep those fins on! Haha
If you could create an anti-air missile to intercept another rocket, that would be really cool.
