Mr. Bob's LDRS project
#1
You may have seem this posted elsewhere but maybe not. Here is Polish Thunder III. it will be going up at LDRS. 9' tall 5.5" diameter. 3 54mm motor tubes. Basicly a clone of a LOC King Viper. But I am using Phlexable Phenolic tubing and 3/8" centering rings. Planning on demoing 3 new AT J250W DMS motors in it.

Great looking build Bob! My wife would love it (former Twardowski)
I am looking forward to seeing the new 250W DMS motors, especially a cluster of 3.
Were there any specific issues you encountered in working with phenolic tubing in your build (or any tips/tricks you might have utilized)?

It is a great looking build and I have seen pieces of it in your shop. I wish I could make it to LDRS to see it in flight. You will have to launch it again for us out here at some point.

Phlexable Phenolic is not brittle like standard Phenolic. It has some give to it. One thing I like to do is take a tube and let it fall on the cement floor. regular Phenolis will crack or shatter. but not this stuff. The Spirals are a little smaller then your regular Phenolic also. If I have the time I will use auto bondo spot putty (red or green) and fill in the cracks. It sands down easily. But on this project I was in a rush (I didn't feel like sanding a 9' rocket Big Grin ). Swing by my Vendor spot and I will jabber away with you and you can check it out close and personal.
Originally it was going to fly at Thunderstruck 6 but the field was lost.
Indiana rocketry has a couple good replacement fields in the works and I also fly with Michiana at Three Oaks in the cold (Er sometimes FREEZING) time of the year Nov-April. so it will be more then a 1 shot wonder.

And a real King is coming to address the situation.

Bob is doing a cluster...

The relay boxes out by the pad are terrified.

Seriously though...Good luck Bob!

If you guys need power for clusters, I added some HUGE freeking batteries this spring! Clusters NOT a problem.
