"I have too many rockets," said no one ever.

Brilliant video. Great help.

great video! any tips for how to pack the chute so it has the best chance of working? Practically, a streamer looks better but chutes are fun

doesn't that mount method put the cord RIGHT in the path of the ejection charge gas and heat? How does that work?

This was so helpful! Thank you so much 😊

Elmers glue on a model rocket is diabolic

Thank you so much for the build video. I learn best being an auditory learner.

Please help me understand... why not put the forward engine mount ring up further forward? it doesn't seem to be helping with fin mount etc... and you quibbled about motor wobble at the closser placement

Super nice flights great job

Thanks! This is timely: LOC discounted this kit on black Friday so now one is on its way to my house. After building several Estes kits and attending a high-power launch it seemed like the right time to try something bigger, and your pair of videos answers a bunch of questions in advance.

My daughters and I built one of these employing your supplements to the kit instructions. When we prepped it to fly, the motor was exceptionally loose fitting. I put a tiny bit of masking tape on the motor to keep it from falling out on the pad. The rocket flew quite well, however at ejection, the styrofoam ball blew into 3 pieces. Looking at the remains, it seems the engine block blasted out forward like a shotgun wad and caused the destruction. Such an odd rocket, we are gonna try again.

Perfect video

I remember these from like 10 years ago when they were sold separately...didn't know they were still available....cool.

When doing the Fillets on the fins could i use an epoxy putty?

Really nice flights. Awesome job!!

Congratulations on a successful day of launching!

Great flights guys ! Like those close recoveries

How did you paint the nose cone black through the lattice? If I had read ahead I would have painted the capsule before attaching the tower!

I dry fit all the fin bits and beveled them before gluing.

My 3 capsule pieces were too large to fit in the base groove. I had to sand one edge down a LOT to get it to fit. Ultimately it did.

Can I request you do the estes Explorer Aquarius? It looks like they may not be producing it anymore.

1:18:35 the forbidden peanut butter

Excellent tutorial! Thank you for explaining everything in detail.

Hello, I was wondering, since the parachute has the protection around it, would it be better to insert that into the rocket first and then the shock cord, so it would be protected from the hot gasses? Also, the parachute would help push the shock cord out of the body tube. Great job on the Rocket! Thank you for taking the time to share.

Like your body tube cradle you made,great idea

Why use CA to tack the fins to the motor mount? Why not use epoxy, which is much stronger?

I was expecting a promo for Wendy's

I hate music.

Is this a BT-50 tube???

Where do you get the longer rivets?

I love the KSR-420. It's just an atteactive design. I've not built the Rocketarium kit but I did build a smaller (BT-55) scratch-built version. I have wanted to build a 4" high-power version but have never gotten around to it. Lovely work on this one.

You gotta make it so we can see the WHOLE wocket when you are done! 😱😁👍👍🇺🇸

A viewer pointed out the the fins should go the other direction than how I built it. He was correct, but the rocket will fly with the fins in either direction.

I like these videos but they would be significantly improved by showing a launch at the end.

"white glue or wood glue" what happened to your "white wood glue"?

Dave, maybe it was just my perception, but it appeared as if the fins were installed facing the wrong direction. It looks like they should have more of a forward looking sweep to them. I can’t believe that Quest quality control didn’t catch the error in the instructions that you are to glue the NC in and then later attach a chute to it…….. I have a Penetrator somewhere in my stash. You motivated me to go dig it out and build it. As usual, I always enjoy watching your builds!

This liquid glue is also on Amazon

That TAMIA liquid glue, Is great, hold your two pieces together,take and touch the tip of the brush on the joint where the two pieces come together.It will wick in the joint & follow it. Hold for OHHH 20-30 second & set it to aside. To get 100% cure STRENGTH of glue"for 24 hrs.

Nice work. My kit was terribly manufactured, the rings had an ID that was so small that they would not slide over the tube, at all. I literally needed to use glue to lube its path. That said, hopefully they will do a better job making these, as it's very discouraging for kids to struggle with terrible manufacturing

Great video Dave! I learn something every time I watch!

you have no idea how much this helped me, thanks so much!!

At 16:24 you could use epoxy, it’s more “slidey” and less grabby. This also applies to couplers, rings, thrust blocks, motor mounts or any place where wood glue can grab before you get your part positioned. You can also position a part absent glue and wick a little CA in to the joint.

Here's a little trick for the motor mount at 31:15. Slide both rings on to the tube and inch or two.. Push the spoked ring down on to the solid one. Apply CA glue along one side of each spoke on the solid ring. Rotate the spoked ring on to the glue. This ensures the center holes are in perfect alignment. Apply glue to the end of the tube and slide the ring assembly down on to it. Perfectly done.

Painting over a gloss undercoat is definitely on the trickier end of things.

Nice build video. Good pace and thorough instruction. Interesting that they called it the "Mars Ascent Vehicle". I would think they need to work on a "Mars Descent Vehicle" before they get to one that can ascend.

Enjoy your videos! Thanks for another. One question: why not insert the screw-eye into the upper centering ring prior to installing the ring onto the motor mount?

Short and sweet.

I like this rocket, gotta get me one! 😁🤪👍👍🇺🇸

That swivel hack is brilliant!!!

For my 8th grade project in 1979 I built this one. I painted it "desert camo" with what was in my garage. It was a decoration in my room until I moved out. I recently bought one for myself and one for my granddaughter.
