In my instructions for my HL, It calls for:
Make a mark 11" from the end of the motor mount tube along the
air frame and drill the overflow tube hole using a 3/8" drill bit making
sure to extend the hole from the outside of the air frame into the
motor mount tube.
This is a 54mm motor mount tube. The rocket is Hybrid ready. A longer
motor mount.
Is this hole required if I am not going to use Hybrid?
This is a stock build, no modifications.
Hi Mike-
If you are not going to fly hybrids, this hole is not needed...
