Got my 20 year old ALPS printer working again with a 20 year old IBM Thinkpad 770 running Win98. Printer and laptop have been in a box for at least a decade, along with about 30 ink cartridges (6 white) and a pile of waterslide decal paper. I feel some scale clones coming on. :cool:
 
Inventoried my MadCow Black Friday delivery. Mongoose 29, a thin wall glass 54mm and a carbon 54mm with nose cones for scratch builds. Loki 54/4000 included for scale and inspiration. Fin stock for the 54s should be here next week.

Hello, my name is AeroAggie and I'm a minimum diameter-aholic. These join a Go Devil 54 and two Mongoose 38s on the build pile, and completed but not flown Go Devil 38 and Tomach 54. I'm hoping to get all of these built over the next couple of months and test flown over the spring and summer before LDRS gets here, then bring out the Loki 38/1200, 54/2800, and 54/4000 for some J, K, and L goodness.
 
Bought a used AT38-720 off the forum today. One man’s old used trash is another’s treasure to L2.
 
Ended up pushing it out forward through the fincan, only to find this:
Had you glued the forward closure into the liner? I have seen similar to yours before and the recommendation I heard was to glue the forward closure to the liner. I have been doing that for the last couple of flights as I don't want to destroy a casing. There is a thread discussing it somewhere.
 
Flew a few mid-power flights and did some ejection tests on my Broken Arrow 54 at our monthly Tripoli Vegas launch. The weather was amazing.
 
skywolf-I405W-2.jpg Flew my 4" Skywolf on an Loki I405W with motor reject on a 15 year old reload. Recovered on the far side of the road. I was a little nervous about the delay because of the age but it worked fine.

Club VP gave me a 15 yr old rocket before last meeting. Said he wouldn't get around to building it. Looked like it was in good shape and everything is there.

Only problem I could find: Its a 4" kit with a 29mm hole...... that wont do

Checked out the fin mounting system

Contacted a club friend with a 3d printer and now it's much better. Just need to cut down the fins by 1/5"

Hi,

Kids, (2 at 11 years old) and I have been building a couple rockets for them. One is a LOC Graduator, and another is a LOC Minni Mag. It was a beautiful day today so we flew them both. Starting with some small engines for low flights. Flew the Graduator on a Estes E12-4. What a nice slow flight. Was just beautiful. 4 second delay was perfect as predicted and it looked great. Flew the Minni Mag on a Cesaroni G80-14A Skidmark. The fight was fantastic. Drilled the ejection delay to -9 but it was still a bit long (Rocksim said 4 sec and it was right). On only a 400' flight a one second longer delay is a big deal. Looked pretty dramatic when the ejection happened as it was only at about 200'. Was still a great recovery and a soft landing. Actually the second or two of dramatic recovery delay was great at such a low altitude. Had some friends over and with our kids it was a great show. Everyone was gasping as it was headed to the frozen tundra.

Very good day!!!
 
What's the material and surface of polecat tubes?
It is a fiberglassed cardboard tube. No peel ply layer is used and the surface is all open weave with irregularities (bumps and the overlap line) to contend with. Makes for a light and strong tube, but part of the Polecat experience is dealing with it.

Got Further Assembly Required loaded and ready for its first flight tomorrow. Going to fly on a F40, assuming the copperhead will work...

Drag race with Vertigo II on an F40! (your rail has two sides right?)

If I had enough left over, I could bolt another rail section to the fire wall of my liquid stand to use as a launch pad... Alas, I'm down to 3 feet of 8020. We could go on both sides of the 6 foot rail, but I think the fin interaction would be interesting...
 
Estes javelin is too good of a glider. Emailed Estes but they don’t ship to Canada !?! You’d think I was living in a remote country.
