I have used an AT 38mm forward closure that had the delay well drilled out and an I-Bolt installed with a nut and washer on the inside. the rest of the delay well were the delay grain would have been…   Read more»

I600 for SSSSRoadrunner F60 for SSSEstes D12 for Low & Slow

so what is the SSSS motor this year? I wasn’t at the meeting… did someone say I600? I am going to fly an I600 for the alphabet contest, assuming I don’t stumble along the way… Since I biffed two A’s,…   Read more»

I thought the threaded closures were only 54mm & above. I called Wildman, and sure enough he had them. I had credit I wanted to use, sorry Tim, but I’ll definitely be getting the motor for this, and the alphabet…   Read more»

Tim Thomas (lawndartman), of GLR fame, sells threaded forward closures. Check with him, that way you won’t waste or damage a non-threaded, sealed forward closure.

If you don’t want to use a delay or smoke grain put the nut on the inside for more strength.If you’re talking Aerotech hardware, you’re guaranteeing a front closure blowout by leaving out the delay. The motor structure relies on…   Read more»

I didn’t know that. That’s easier.Thanks

I would drill and tap thru to get the most threads possible in the foward closure. You can use a nut on the threaded portion of the eyebolt to lock the eyebolt to the closure. It also helps to set…   Read more»

They make thread front closures. If you tapped and drilled a regular closure I think you’d have to fly it on a research day if at all because you modified the motor.Ron

Mike,If you’re going with the CTI J285’s, definitely airstart them! The Perfectflite timer is SO simple to set up, and fully ground test. And with CTI motors, it JUST WORKS. No dark art of igniter augmenting required.If I can just…   Read more»

Nice one Mike. I myself would be too nervous to fly it after that much work

Yup, your stars and bars are upside down.I’m sure you can fix it with some of that amazing hand-painting talent!Looks awesome. I love the metal fins with rivets look.Ken

They did a fun paint job.I told Him the basic yellow color. But to ‘have at it’and show His creativity.It will change somewhat, when I ad some graphic stuff. But for the mostpart this is it.One section got reversed. So…   Read more»

from an irregular Mike to a regular MikeNice work, Mike. I like the look a lot.

And to do my part, I will give you the L1720 and let you use the hardware for the same price as the K54/ L1030! Got to see this fly!

This is why we love this guy!

8) Mike, WOW ! If I may as to be so bold. First flight, Pro75/3gr. L1720. A 3659nt. 440lb thrust, 2 sec. Add 3 X I345 white Lightning 408 nts. Total of around 4883 nts. That will be a great…   Read more»

WOW…. I will look into it….Thanks

Mike,That is a way cool looking rocket.Why the 5100 Ns limit? If you are Tripoli, you can cluster to over that limit if you are a level 2. I believe the documentation for that rule is on the L3 certification…   Read more»

4000′ to 5000′.Will not know for sure till I have a final weight.
