Subject: [MTMA] GO for Launch - Sunday, November 26, 2017 #go

We are GO for Launch at the Harmon Flying Field on Bartlett Road in Aurora, Ohio, on Sunday, November 26, 2017. Set up before noon; the launch starts at noon.  We will fly until everyone has had enough, or 4:00 pm, whichever comes first.


The weather forecast is calling for temperatures rising from 37 to 40 under mostly sunny skies with winds out of the west at 8 to 15 mph and no chance of rain.


See you there!

Essential if you are thinking about a cert, fairly easy to determine using open rocket or rocksim.

I’ll be happy to assist with any questions, and would be happy to sign off on the flight when the time comes.

Best advice to keep it simple, just get it up and back, build for strength, if you are not comfortable with electronics, hold off.  You can use a 4 inch diameter design and keep it under 1500 feet without even a chute release.

I second what Wolf said about a sim. OpenRocket is free. I personally use Rocksim but that's because I run Mac computers and OpenRocket is Java-based and is not always Mac-friendly. you can't beat the price though! I'm also embarking on a quest to reach Level 1. I just have to get off my caboose and do it! :) I think the hardest part is finding a local field that actually has launches.

That will work, there are pre made files that you can find for that rocket, search the LOC website for a rocksim file, it can open in open rocket, easy peasy

Tom, the benefit of using a kit is that it is most likely a stable rocket.  I know that you'll still need to demonstrate stability on paper.  Open Rocket will easily and accurately measure Cp on a simple rocket like your Loc IV.  Save the $100+ dollars that you'd spend on rocksim for motors.

Do you have a laptop?

Bring it with you on December 2.  I'll show you some stuff if you've not figured it out by then.

Weigh each component of your Loc IV and use those values in the simulator.  You can use generic values, but you want more better, right?

You need to get comfortable with being able to accurately determine the Center of Gravity and Center of Pressure of your rocket. 

As for doing a Level 1 cert build that's pretty easy.  Buy kit.  Build kit.  Fly kit.  I scratch built an upscaled Big Bertha using a 3-inch mailing tube, plywood rings and fins I cut myself, and a nose cone I made out of fiberglass and epoxy.  Flew it with a mid-H motor.  Uneventful, nominal flight.  Flying an H motor is no big deal.

Sure no problem, I’ll be happy to walk you thru the rocksim, that’s what I use

Essential if you are thinking about a cert, fairly easy to determine using open rocket or rocksim.

I’ll be happy to assist with any questions, and would be happy to sign off on the flight when the time comes.

Best advice to keep it simple, just get it up and back, build for strength, if you are not comfortable with electronics, hold off.  You can use a 4 inch diameter design and keep it under 1500 feet without even a chute release.

I second what Wolf said about a sim. OpenRocket is free. I personally use Rocksim but that's because I run Mac computers and OpenRocket is Java-based and is not always Mac-friendly. you can't beat the price though!

Thanks Wolf. This other group list is starting to simply not function, and we need to do something... 

Happy Thanksgiving Everybody !

Hey Guys,

Please refresh my memory on why we changed over from YAhoogroups to Group.io

Another list I am on has been on Yahoogroups fro years, but it is starting to have technical problems. I was wondering if that was our reason for switching, and if so if I should recommend the same to my other group…

Thanks,

 Hi All,

Time to nail down the Christmas Party. It needs to be Saturday 12/9. Sorry to those that wanted it on the 16th, I had to pull that off the table for personal reasons.

So:

Sat, Dec 9, 2017

4:00 pm — ???


Pot Luck, I’ll ask everyone to bring a dish to share, please coordinate with me when you RSVP.

I will provide Pasta, Soft Drinks, and wine. Mark, Beer please, just as last year ?

We will also have a white elephant gift exchange, so keep that in mind when reviewing your build piles !

If this turns into a late night build session so much the better, BYOB to share for that. I have plenty, just always interested in trying new stuff…

Mark, would you please post this to the FB page as well.

Hope to see you all here !

Happy Thanksgiving,

John

I couldn't think of it previously and I'm glad you mentioned it. My concern is and will need help with what you said below:

"accurately determine the Center of Gravity and Center of Pressure of your rocket.  "
