Red Glare - What Are You Flying?

Finally got my Frenzy XXL up in the air for the first time in three years. This was on a 6 grain 75mm Aerotech M1850 in CTI hardware.

I had a great time. Didn't get to fly high as my GPS tracker didn't want to get a lock so I flew the rocket on a G to 2900ft instead of an H or I. I have an I224 for next time though.

Here are my videos from a camera I set out much closer than we could be. First one is the Q motor that got burned and second is Tom's flight.

Got my L3 this weekend on an M1780 to 6000ft. Was a great flight and it recovered perfectly just by the away cells.

Video of the mega Deuces Wild captured by a friend. Anybody seen a video that captures the whole flight any better?

Talking to its owners afterward they said the nozzle of the failed engine had blown out. Stepping through frames in this video, I think you can see that happen just before the other motor ignites. The motor lights, there's a big smoke puff, and then it's just on fire from there on without meaningful pressure. The motor on the left in these stills is the failed motor.

Great pics, everyone! Sure wish I could have been there.

Here is the video I shot - it is in 4K. Only issue is I missed the middle of the flight - when it started to crash, the crowd moved and I had to move with it. Caught up with it before the rocket hit the ground.

I edited a portion at the end to include just the launch itself at 1 frame per second. You can see the nozzle get ejected, the left motor flame out, then disaster begin as the right motor ignites successfully and begins a slow spiral to the ground.

It was great meeting you at Red Glare and your flights were all amazing! Your second flight of the Goblin was my favorite of the launch!! It went straight as an arrow. You are a master craftsman.

Here is my launch report. They put on an excellent, well run launch. It was a three-day launch and I attended the last two days. I had a full M that I wanted to fly in a 5.5" diameter fiberglass rocket and I had a nice flight to 14,000 feet and change. The weather was perfect on Saturday and lots of neat rockets flew. The launch was great for all types of fliers and the A rack was just as full as the away cell. I highly recommend attending this launch in the coming years.

Old LOC Tri-Star from the early 1990s on 3x G77-7. Only two lit and the rocket flew okay albeit lower and not straight. Photo credit Ken Potter
Launch Pad AS-37 Martel - Aerotech E20-4. It did not fly straight and I am worried the motor is too far forward. It still flew safely and recovered without issue. Photo credit Ken Potter
K-Pyramid which is a 18"-wide pyramid weighting 18 pounds at lift off. Aerotech K680-R. It flew straight and recovered well, but unfortunately it drifted towards the road and hit hard on asphalt. Minor damage and it can be repaired with some touch-up epoxy and paint. Photo credit Ken Potter
I flew the Martel again on a E20-4. It still did not flight straight, though it was quite windy and it could have simply weather cocked. I want to try it again on a calm day to better understand it. Photo credit Ken Potter

Great flights, Alex - so glad you could make it down for the launch! Loved that DX3 on the M1939 - amazing flight!

Where do I get one of these, or at least plans for one? They're really entertaining.

Still using Duplicolor "Paint Shop" lacquer? There's only one word for your rockets "EXQUISITE"

Still using Duplicolor "Paint Shop" lacquer? There's only one word for your rockets "EXQUISITE"

Thanks, that one was painted with Restoration Shop lacquer from TCP global. I like Duplicolor Paint Shop lacquer but the color selection is very limited.

 

[Hobie1dog]

With the Restoration Shop paint being $150 a quart, and the Paint Shop brand being only $35 a quart, I don't have any choice living on Social Security income. Luckily, all of the colors that I really like are included in the Paint Shop selections. I grew up spraying lacquer and now it comes ready to spray/no mixing/thinning. Also being able to drive 3 miles and get a quart at the local Advance or AutoZone, really makes it convenient.

Is this a Wildman Goblin Kit and what altitudes are you getting on "M" motors?

Is this a Wildman Goblin Kit and what altitudes are you getting on "M" motors?

This is a custom Wildman kit. When I talked to Tim @WILDMANRS last year about doing a large Goblin with a cluster motor mount, he suggested using a carbon fiber honeycomb material he had been testing out for the fins. So, we traded designs back and forth and he sent me the tubes, nosecone and fins cut to my specifications for a 4 x 75mm motor mount. I designed and CNCed all the internal components. Tim is now selling this honeycomb material as an option on the 8" Goblin, but if you want to do a cluster, you will have to do the interior design yourself. I intend to post up a build thread soon.

If you buy the unmodified version of this rocket, it will come with a 98mm mount. I would expect to see about 5000 feet on a small M like the M1500.

Since I built it out as a 4 motor cluster, I can greatly expand the top end of total impulse. That flight on 4 x K1000 was the equivalent of an M4185 (a 98% M). It flew to 9000 at just under Mach 1.

Flying this on 4 x M2050s, for example, would yield an O8137 equivalent, which sims out to about 15,000 feet at Mach 1.5
