I replaced the stock fiberglass roll with my own Mylar for the thrust tube as it was a little short for where I mounted my Lander DF. I may use the fiberglass roll to smooth out the air intake area when I clean up the intake ducting.

My normal FSA was used from other projects as it is a good compromise between thrust and speed. The tube length of 12-1/2" was used to allow it to exit the tail. After taping the thrust tube to the DF, I sealed the opening for the motor wires with some Plumber's GOOP.

I added some black paint to the rear former to enhance the look.

The bottom hatch was held in place with some clear 3M Scotchcal strips.
