Brief:
A 38mm minimum diameter all fiberglass rocket of unparalleled quality.

Rocket Pic

Construction:
The rocket airframe is spiral wound solid fiberglass tubing. The kit included the main airframe plus a payload section, with a fiberglass coupler and plywood bulkhead. The nose cone is solid resin, with no casting marks. The fins are the molded Acme 38mm fin canister. Motor retention is provided by an AeroPak 38mm aluminum retainer. The shock cord is Kevlar®, the chute by Rocketman, and Alan also included a Nomex® heat shield. Alan even included the Acme conformal launch lugs.

Rocket PicFor a rocket that can break Mach 1 without a sweat, this is one easy rocket to put together. The hardest part is milling out the bottom of the fin canister to fit over the AeroPak retainer....just cosmetic. The whole kit can be easily put together in the time it takes 30min epoxy to dry. Just make sure that you sand all of the areas to be epoxied....remember, it's fiberglass, and has to be grooved. Because of the fin canister, this kit is as easy as the Estes E2X kits....I would consider it "almost ready to fly"!

Finishing:
What can I say? Solid fiberglass...no spiral lines, a nose cone without any injection marks....this rocket is almost pristine. The fin canister is the only part that needs a little work. But a coat of finishing epoxy, and you are in business.

Construction Rating: 5 out of 5

Flight:
I've flown it 3 times now. I195J, I211W, I435T. The 195J came in ballistic because of a bad ejection charge. Alan sent me a new airframe and it has been rebuilt. The I435T broke mach. Because of the Nomex® shield, no wadding is required. The flight was arrow straight right up to 5000' and came down quite fast on that tiny chute. I'd love to see one of the bigger Kosdon motors in this tiny thing.

Recovery:
The chute is small, but still tough to get into the frame. Alan suggests using a twisting motion to slip it into the frame. I packed the cord in first, and then the chute lines, followed by the chute. The recovery is very fast on the tiny chute, but that is intended because of the super high flights. The Acme canister can take quite a beating, however.

Flight Rating: 4 out of 5

Summary:
This has got to be the highest quality kit I have put together to date. Alan took every great product on the market and put a kit together. The only problem is that I want to fly a 54mm J800! Guess what....the Transonic II is the 54mm version! The kits are, however, very expensive. But, there's always room for the Ferrari.

Overall Rating: 5 out of 5

I have flown the Transonic about 6 times now and it is a great rocket. Several things-it takes some dexterity to glue the shock cord to the inside of the airframe- I glued mine farther down the tube than recommended to leave more room for the chute-I used a dowel with sand paper on it to scuff up the inside of the airframe. It is VERY important to get the fin can on squarely-straight, it is easy to do if you take some time. I also came up with positive nose cone retention to the payload section I used plastic gromets-that are removable. The components are top quality and the instructions are excellent-they even include some altitude simulations. I recommend the Transonic highly-along with Hawk Mountain-their service is great.

I have the Raptor & Transsonic 2. I scratch built the Transonic 1 but wanted a longer frame 60" so I used and extra tube and coupler. If you want more 'chute room don"t glue the shockcord to anything. Run the shockcord through air frame, double it over and sew with Kevlar thread. Glue with CA to hold in place while sewing. Shockcord fold is about 1/4". Slid in your Aerotech motor, pull shockcord to motor aft closer folded over tab point to nozzle and screw on an Aeropack retainer. Now you have a nice smooth surface inside your air frame with lots of extra inches for 'chute & whatever. The whole shockcord is now removable for inspection and replacement. It works. 18 flights on same shockcord. Must use flat shockcord. Works on any rocket with an Aeropack retainer.
