If you like the regular Der Red Max, you'll go gaga over the Pro Series II Mega Max!  I built this one kind of quickly along with the Pro Series II Nike Smoke, so construction was somewhat of a blur, but I was very impressed with the materials and design.  I felt you get a lot of value for your money with this one...well worth the coin!  Also the kit builds up to quite an impressive wife and child each exclaimed "Wow! That's a BIG Rocket!" and each of my non-"rockethead" friends liked it as well.  Just a note though that if you get this kit as a first step on your road to BIG rockets, the motors start getting more expensive or more complex.  The suggested F50-6 motor retails for over twenty dollars.


Giant 16.5" nosecone, a heavy duty 4" main body tube and plywood centering rings are some of the more impressive parts.  Also included is the Estes Pro Series II motor retainer...I love these since they are simple, convenient and strong (note you need to epoxy the retainer to the rocket).  Fins are massive and made strong with a plywood center rib structure which is sandwiched with balsa sheets.  I thought this was a very clever way to have the fins strong, big and not overweight.  Some may think the balsa sheeting is too soft for such a big rocket, but I felt they were fine. Another impressive addition is 4 sheets of BIG decals...likely the largest I've ever seen.  Quite a lot of bang for your bucks I felt.

Model Rocket Building: Estes Apollo Little Joe II, Background
Here's the Little Joe I remembered wanting. The BIG 1/45 Scale Little Joe II from the 1969 Centuri catalog. To see the catalog, CLICK HERE But $12.95? All I could afford was the smaller 1/100th scale Little Joe II. The fin fairings and some trim was vacuum formed. They were lightweight but fragile, much like the Centuri Saturn V fins and fairings incorporated into the Estes re-issue Saturn V kits. The "metalized" wrap was pre-installed at the factory. To see the original Centuri instructions: CLICK HERE The body and capsule came down separately on two 24" parachutes. A three engine cluster. ...

Model Rocket Building: Estes STM-012 Kitbash to the B32-M Spike, Background
Well, I thought it might work! I bought two Estes STM-012 kits on Ebay with the hopes of kit-bashing one of them into an AMRAAM. It never even occurred to me that the STM-012 model would have three through-the-wall fins. The AMRAAM has two sets of four fins. I would have to buy a couple new lengths of BT-60 to do the conversion. That, and the STM-012 nose cone was long! So the kits sat for a few months with me wondering what to do with them. Then I remembered this design from Madcow: The AGM-33 Pike . I've always like the looks of this one, I did the instructions for their 1.6" diameter kit. ...

Model Rocket Building: Corner Chip Fill - TIP
Well, we've all been there - the balsa grain runs in such a way that the trailing edge tip can break off. If the tip break is small you can fill it. Sand off some balsa dust from some scrap balsa. Don't sneeze. Apply some yellow wood glue to the broken corner. Use wood glue for this, yellow glue can be easily sanded. Press the glued corner into the balsa dust pile from all sides. Let the balsa dust and glue dry. Note in the inset picture that the dust and glue is a little larger than the chip area. Here's the same filled corner after filling and sanding to surface. Not perfect, but ...

Rocket Dungeon: Mini Higgs build, part 1
I dug into the build at the very best place to start - at the very beginning, which in this case is the motor mount. This is not so different than any other LPR mount. It includes rings (squares in this case), a motor clip, motor block, etc. The mount also has two normal round rings to hold the clip securely in place. The Kevlar leader is attached behind the forward square centering ring. Unlike any kit I've had, it also includes a section of shrink tube to protect the lower several inches of the Kevlar. I pretty much built this stock. If I want to put a bigger motor in one, I will have to ...

Model Rocket Building: Carded Red Max Build, Part 1, Parts
I've seen a few pictures of "Rocket Families" on the forums. The Red Max is a favorite with the Estes Mini Max (BT-50 based), standard Red Max (BT-60 based) and Mega Red Max. Well, how about a smaller BT-5 version for 13mm engines? This one is tiny at just 5 1/4" tall! It performs like a BT-5 Mosquito. At one time I had a little carded Red Max model. It was a BT-5 diameter with a Micro Max engine mount. I lost it somewhere along the way and wanted to make another one. After a few searches I couldn't find it. I thought it might be at Wayne Hill's Rocketry Blog - CLICK HERE There are many ...
