You fly heavy planes without Robart struts.
What's the Avenger, 62 oz?
What are you building?
Where's your Build Thread?
The Avenger is not heavy, its a big airplane,, its not a lightweight, but certainly not heavy,,
I am building a new PA airplane,, not ready for display yet,, its in "stealth mode"
and my 109 was not heavy,, it was actually light for its size,, 670 square inches,, and 63 ounces ready to fly,,
my electra jet was not heavy,,
all these have flown,, yours,, not so much
