Does anyone have or had .30 waco from hobby people, i need cg location for this plane, cant use calculator...
Thanx Bob

Perhaps ask in the ARF forum.

There's a little trick for using the calculator. Use the most forward leading edge and the most rear trailing edge and treat that as just one wing. Use the position it gives you and start with it a 1/4 to 3/8 inch further forward to start with.

Yes, I have that plane, it's a great little flyer. Too bad they aren't selling it in the states anymore. Unfortunatly, I crashed mine a little while back (flying a black and grey small bipe at dusk is not the smartest thing to do). I have 2 more in the box though, so I'll get one flying again soon.

As for CG, If I recall, it was just a bit ahead of the lower wing LE. I had an OS .32F with pitts muffler in mine, and had to mount some weight on an extra motor mount inside the cowl.

I'll see if I can quickly dig up a better answer soon. (I'd say "tonight", but I have a ton of stuff to do at home, so I don't now how much shop time I'll have).

Btw, while the link above doesn't work for me, there were some threads on here about that bipe a while back.
