MPC Cadet Cruiser FIX! Part 1

After two unstable flights of the MPC Cadet Cruiser I decided to make it work!
Built from the kit instructions, the engine sticks 3/4" out the back!
That alone could throw off the C/G position. I'll make a new mount where the engine only extends by 1/4".
The fin can and engine out 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 twisting broke the tube sides off the plastic fin can.
From the top the engine block was grabbed and twisted.
The old tube was slid out the top.
The new engine mount tube is a standard 2 3/4" long BT-20.
The kit engine hook was thrown away, it wasn't spring steel and prone to bending.
The hook was held with a wrap of Scotch tape. Electrical tape would have been too thick.
