Andrew I admire your desire to push things to the edge. I enjoy this thread because it points out all of the concerns and issues a few of which you and I have discussed. The key is the try and figure...
I use 80 up to 1500 just depending on the finish I need. I use polishing compounds if I need to go beyond 1500 grit. I use a lot of paper and the prices at the box stores are ridiculous. I get my...
Yes we will have a shorted check at the box. Safety is #1. I am not sure about the flyback diode I will have to do a little investigating. The setup runs 433 MHz but so far no issues but something to...
I work with a school that needed a remote control launch system for rocketry. I found a company RFControlSystems http://www.rfcontrolsystem.com/index.php?main_page=index that has a lot of hardware...
What size body tubes do you use?
I used one of these until I had the space for a drill press. There are several companies that make the drill guide. http://www.rockler.com/product.cfm?page=2405
I also use a DDC22 for redundancy. I call it cheap insurance. Works flawlessly and extremely simple to use.
A miter saw with a metal cutting blade makes a smooth cut in FG and CF.
Does anyone know if there is an official high school rocket altitude record? I found one article on the internet about a school that expected a rocket to hit 100K and set the high school record but I...
I have ordered nose cones from them. The part shipped fast and was exactly what I needed.
Do you have a Rocksim file so we can see the rocket design?
You can order 4F powder online from Graf and Son's. http://www.grafs.com/ . When I purchased from them 3 years ago they required the purchase of 2lbs not sure if that is still a requriement.
My guess is the ding was made prior to the motor being inserted in the rocket and the heat accentuated the appearance.
100% agree with CoyoteNumber2 heat is the way to go. I had a stuck liner. I put the case in the sun on a 90+ degree day for 3 hours. I used the forward closure to push the line out. Took no effort at...
I take back anything good I said about Rustoleums new Univeral paint in the funky can. I used the paint 4 weeks ago with good results. Today I wanted to do a little touch up spraying on the same...
My L2 was built with 5 minute epoxy and 15 minute Bob Smith epoxy. The filler definitely makes the epoxy easier to work with since it doesn't run. The L2 rockety flew many times over 5 years until a...
I tried the Rustoleum Universal paint which comes in this style can. The paint is a primer and paint combo. I used it to spray a fiberglass nosecone. I like the paint a lot. It dries fast, sanding is...
Gluing aluminun foil to the fins can help. Light reflecting off the fins will make it twinkle coming down. Doesn't always work but better than a standard paint job.
I set the angle using the wooden "guide" for lack of a better term. The guide I use most is around 12 degrees. It takes a bit of trial and error so I use a piece of scrap to get the guide the right...
Looks good. I don't like sanding bevels. OK I don't like sanding anything so I use a small table saw to cut my bevels.
What size rocket do you plan to build, will it be above Mach very long? Generally US Composites is fine for CF work. I use it for FG and CF without any issues. I also like Aeropoxy although it is...
I emailed Estes about the issue with their pricing. I suggested they list the hazmat fee seperately and include some verbiage about the fee being per order not per motor and the max # of motors per...
I am not sure what is causing the problem but I have found a work around. You have 5 body tubes under the sustainer. I deleted body tube#3 which has the upper fins. Once I deleted the tube it would...
Call the manufacturer to get a G rating and their input.
I've used the same bottle of CA sometimes 4-6 months many times. The only issue is it thickens slightly. It still cures fine. I've never heard of rubber mixed CA. Is the purpose to make it somewhat...
I love the KISS principle and it looks like the extender meets the requirements. Nice addition to an already great altimeter. Great job.
I've used Giant Leaps before never had a problem. Now I make my own using centering rings and a motor mount tubes. Not as appealing to look at like the Aeropack but it works.
Great cases. Never had any problems with them.
I would wrap the coupler with something thin like Saran Wrap and slide the 1" airframe piece over the Saran wrap. It will keep the epoxy from soaking into the coupler. Butcher paper works well but is...
I have run XP Pro SP3 and Rocksim without any problems. I am now running Windows 7. You might try stopping all background programs and any antivirus software you are running. If Rocksim works then...
