Nice work yet again, Mike. By the way, shhhhhh… 😯

with Nice Rockets.I too hang the from the ceiling. We have two cats that think rockets standing need to be knocked over.Looks like a cool bird. The paint scheme seems familiar…

Yes. And the picture I use in the forum is the 4″ on a J500MGlast year.

Did you fly the 4″ Thor-X this month? Those are cool looking birds.

Does beveling the root of the fin at a 45 degree help to bond it at all – seems like the increase in surface area would help with the epoxy. I know it helped immensely with my aluminum fins to…   Read more»

If you do use the slots, make sure and wrap the motor in Mylar or wax paper.That’s exactly what I was going to do. I’m using some high-strength epoxy and will post-cure it properly. I might drill some tiny holes…   Read more»

Laying glass tip-to-tip is critical if you are going go minimum diameter (in my opinion). I personally like using slots, though some just tack the fins onto the outside. If you do use the slots, make sure and wrap the…   Read more»

I’d love to see it fly. I’m still nervous about those shallow fin mounts, but John W. seems to thrive with them.MHM should be doggie heaven.

That we will enjoy, Dr. J!

I’m stuffing a Cessaroni 6 XGL motor (J-600) into my LDDD. That should be a nice flight. I love that J600 motor.I’m leaving the motor mount out, turning it into a Pro54 minimum diameter rocket 😉 The fins will just…   Read more»

I wanted a DC-30 as it will approach 10,000 feet and I do not want to lose my little doggie!But if you DO lose it, I know someone who will sell you another :DI’m kidding, of course! I hope and…   Read more»

The rocket rage clones I use I have a calculated Cd of 1.9, but I generally use 1.8 to be conservative.Edward

A 96″ Spherachute measures 61″ across at the skirt, so they are about the same size. I’d agree that the ellipsoidal ones have about 0.1 cd better drag, and look cooler, but they seem to be a bit more expensive…   Read more»

semi-ellipsoidal are very efficient but I think the packing depends a lot on the material. I have a 60″ rocket rage clone that holds 15 pounds at 15 fps. I can pack it into 8″ of 2.5″ airframe very comfortably….   Read more»

I’m stuffing a Cessaroni 6 XGL motor (J-600) into my LDDD. I am also putting a DC-30 into a mini-payload bay below the NC with the antenna extending into the NC.My build out weight with the DC-30, main chute deployment…   Read more»

One plug for Spherachutes- they are local out of Greeley. Like many vendors, they will do custom work for modest price. 30.57″ spherachute (equivalent to a 48″ flat) costs $39. These have vent holes at the top, so they seem…   Read more»

8) The Little Dog should be a very tough rocket. I would think that any chute from 24″ to 36″ would do fine. But I like Johns’ idea about the 30″ crossfire. A really sweet chute for 25.00. And a…   Read more»

I use a 30″ CrossFire chute from Top Flight Recovery for most of my 54mm flights http://topflightrecoveryllc.homestead.com/page1.html Gary is one of the most reputable guys in the biz. I have used his stuff almost exclusively and I’ve never damaged my…   Read more»

Given that it is DD, you should plan slow it down plenty with the main, shoot for 15-20 fpm AT 5000′ altitude. RockSim will compute this for you, and you can figure it out using online descent rate calculators. If…   Read more»

Yowza!!!!!!!!!!! very cool photo indeed!
