Bi Slob balance point

[Bill Hodges]

Guys, I am just finishing up a Brodak ARC Bi Slob.  I have searched the instruction book from front to back and can find no mention of the balance point.  Right now, it is balancing dead on the spar.  Is that a good jumping off point or do I need to make some adjustment before the first flight?  Any help will be appreciated.

You mean there's supposed to be a balance point?     I don't know that I can even say Bi-Slobs require any kind of trim... hmm...

You are good to go on the spar..

Bill,
Checked three of them from our club.
Spar seems to be the preferred (or just happens to be  ) location.

I just rechecked mine.  Its about 1/2" fwd of spar on upper wing.

I just pulled out the plans that where in Fling Models and it is 1/2" behind center of the spar. I don't know if thats where everyone is flying them at that but thats what the plans say.
