spar stiffener

[RichardW 0]

I'm replacing the front spar on a kf2. It had the ibeam spar. Does anyone have the instructions on how to place the stiffener?

I didn't make this very clear, I have purchased a new front spar that needs the stiffener. I need to know what the insertion lenght is and to secure it. If someone has that information that they could email me, I would appreciate it. My manual is for the 2 and doesn't have this information.

I’m doing something similar but I planned on building new wings and two new spars and reuse everything else.

my thinking was that the old and new spar will have different strength depending on separate stiffener or not.
