MPC Cadet Cruiser, Part 1 Parts
Here's another of the MPC Round 2 kits. These are not the older MPC rockets from the late 1960s but relabeled Sky model rockets from China. Sky also makes the engines imported and relabeled by Quest. I bought this one on Ebay, a "Buy It Now" for $4.80, too good to pass up. I was a big Looney ...

MPC Cadet Cruiser, Part 2 Engine Mount & Fin Can
"Launch in less than One Hour!" We'll see. I normally take more time building than most. The engine hook isn't spring steel. The bent ends seem a little long. The ends were trimmed back easily with some small wire cutters. The instructions say to "Tape ove the hook with a piece of clear ...

MPC Cadet Cruiser, Part 3, Fin Can & Parachute
Here's an illustration from the instructions - Don't apply glue to the fin can shoulder. You would have glue squeezing out to the outside of the model. Apply the glue inside the tube and slide the fin can into place. the glue remains inside the body tube. Note the engine hook (and engine) ...

MPC Cadet Cruiser, Finished
  The model is cute and the colors bright. It should be a decent B6-4 or C6-5 model. The instructions were vague with too many mistakes. The box says "Flies up to 260 feet! A C6-5 should take this one closer to 600'. The B8-3 engine does not exist. The shock cord was too short, the ...

MPC Cadet Cruiser FIX! Part 1
After two unstable flights of the MPC Cadet Cruiser I decided to make it work! The fin can and engine mount came cleanly off the air frame tube with a little wiggling. The shorter kit engine tube was glued in pretty well. From the rear the tube was grabbed with needle nosed pliers. Some ...

MPC Cadet Cruiser FIX! Part 2
Here's a dry fit of the improved mount. The BT-20 sticks out the back by about 1/8". This puts the engine about 5/8" forward from where is was before. With the engine hook farther up it doesn't move enough to allow the engine to slide in easily. I filed the shallow notch to allow more ...
