This is my second Public Missles Ltd. rocket, but the first one flown. It has a phenolic body tube and "G-10" fiberglass fins with through-the-wall (and to the motor mount) fin mounting. There were no factory problems with the kit. I'm using a ROCKETMAN R4C parachute. I am also using a HeatShield shock cord protector from Pratt Hobbies, and I replaced the elastic shock cord with 9/16" tubular nylon. This is an easy PML kit to build, and much less complicated than my Sudden Rush. I did fill the body tube spirals (with Elmer's Fill 'N' Finish) since the phenolic tubes have such deep grooves. After blowing the end off, I decided to get rid of the piston system. Repairs completed 5/24/98, it is now 6.6" longer and 3.5 oz. heavier. One problem with this kit is the launch lug is too small, it really needs a 3/8" lug given its weight.

| Flt | Date | Motor | Comments |
|---|---|---|---|
| 1) | 3/26/98 | G80-4T | Nice flight, no problems. |
| 2) | 4/23/98 | H123-6W | Nice flight. |
| 3) | 5/07/98 | H123-6W | Nice flight, but blew the end of the body tube off, including all four forward fins, at ejection. I guess I used a little bit too much powder. |
| 4) | 5/25/98 | H123-10W | Drilled the delay a little. Weathercocked. |
| 5) | 6/04/98 | I161-10W | Took off at an angle, I think from too wimpy of a launch rod. |
| 6) | 4/11/99 | I161-10W | Took off at an angle, but a nice flight. |
