Macchi-205MC Contact Points

Milton, when you work through a problem like this, are you using a particular program (ie; airwrench or ACM) or do you just have a knack for numbers, lol.:salute:

I used Notepad; does that count? :) No, I simply use lights to show me where the key things are, like Reference point, Center of Gravity, Main and Tail gear. From there the rest is easy.

EDIT: The reference can be anywhere, but that is your home base. I usually set mine at 25% MAC, and at the thrustline. Once you know where you are working from, then set the CoG at 25% MAC on the thrustline, or 1-2" below. The set your loads, fuel, gear and lights, engine location, and adjust View/eyepoint if necessary. Get rid of 5 decimal places, use no more than 2. Align your contact point data on the commas, use same number of decimal places to make it visually easy to read and detect mistakes. The original points had the left main brake set as 0, tailwheel, and the sound entry for the left main was also 0. Easier to catch that stuff when things are aligned.

I know you're a very busy person, but sometime when you have the ability, I'd like to bend your ear on just how that works. I used to have ACM and loved it, especially for placing the shockwave lights, but it no longer works now that I've switched to a 64bit OS and airwrench might be a good one if I really understood what I was changing, lol.

Anyway, thanks again for the work you do, pretty amazing.:salute:
 
Milton,

What a difference it makes with the new settings. A complete and different aircraft all together. Thanks for taking the time to go through it. :)

Thank you. I would be happy to help. The more of us who can do this, the better off we all will be. Just some basic concepts and understanding is all that is needed, Sparks has this on his website but any graphic to help understanding is better. This shows reference point at the nose. I just always place the aircraft in gmax at the centerline, thrustline, and 25% MAC. Makes everything easier to place for me. Of course, on my models, I get the basic coordinates out of gmax.

Thanks Oleboy. :)
