Hi Oliver,

Thank you very much for your advice. This program really adds true value to really knowing where one is at with there setup. I suspected something was wrong and clearly I see it.
I'm still learning each of the defenitions and playing around with the software. But it looks like I will do some experimenting with linkages and arms.
I will have to locate a copy of the artical you wrote for RCJI. I'm sure all the defenitions and a crash course on how to really use the software. Its been awhile since i've done this and the internet has really turned out very useful for getting back the basics.

I'll let you know soon as I get the Dragon back up in the air with my experiments.

Kind regards,
