RE: Panther
I weighed it last night, 18.75 lbs. I have approx 100 oz tank.
I didn't use any carbon fiber in the tail. I guess I trusted that Ziroli had done this before so knew what it needed.
I figured the glass would add enough strength.
What flight conditions caused the stab to break?
Do I need to reinforce my stab? I would even consider external braces if necessary/
Has anyone had a problem with the strength of the wing tubes?
WD40, how much did your Panther weigh?
