Dynam C-188

[asesso]

I have read through this forum, but I am still confused as to what is the correct CG location for the dynam C188. The wing flairs at the root. Is the CG measured from the edge of the flair or as the instructions seem to suggest from the landing gear location back. What is the correct measurement from each of these points. Some here have said 65mm, but from what starting point? The instructions say 90 to 100mm, again from what starting point?

I can understand the confusion when I look at those diagrams for CG in the instructions. In one picture, it shows the measurement begins where the screws are for the landing gear. In the other, it shows it at the leading edge of the wingtip. On this plane, that's quite a difference. BUT, also know that the CG can vary up to 5mm and I can tell you that even this is not a big deal for this plane.
For me, I always use the point where the wing touches the fuselage. On this plane, it's where the orange meets the white. I don't concern myself with how the wing tapers at the fuse. I always use where it touches the fuse (unless specifically told otherwise). Start your measurement from there and measure back to about 97.5mm (1/2 way between 95-100). Then move that spot away from the fuse a few inches just so you can actually easily put your fingers (or your balancer pads) on that mark. You are balancing this plane upside down, right? Low wings balance upside down, high wing balance right side up, mid wing do both and go with the one where the plane tends to hold the best. If you've got more weight of the plane above your fingers or the pads, it will tend to more easily teeter. If that's the case, flip it over. (It's like .............. is it easier to hold a broomstick vertical by holding it at the top end or trying to balance it at the bottom end?)

PS. Of course, some will disagree with me on what I just said, but that's their prerogative. It's their plane and each owner can balance it as they please. My "Dusty" is balanced the way I said and it's still flying after over 2 years.

Hello Friends, I've was wondering if any of you have ever made or modified a set of boom sprayers to look like a crop duster on the C188 to do a scale look of spray booms?
