Chad,
I know you are knowledgeable about alot and I'm not trying to start an argument, lol.
I believe what you are saying with your planes, but don't see how it's possible that a few pounds if moved from center, to bottom or to top of the fusalage wouldn't make any difference in flight. I hope you can see what I'm saying.
Do you fly foamies? Haven't you had this issue with them? I have. I even have this problem on the simulator. I'm sure everyone has a simulator by now. Try changing the vertical cg in the fuse and see what difference it makes. If nothing else, it's an interesting experiment.
There is alot more to make a plane fly correctly, as you well know, than just setting incidence's and lateral balance. I know that you understand this Chad, not trying to state otherwise.
I just thought I would mention it as it's not something that gets discussed in the forums. But locally, here in Northern California we have discussed it with the electrics.
If faced with the same situation with the oxalys, or any plane with a one piece wing, I would probably mount them there also and just deal with it in mixes. Only problem with that is that I don't like mixes. I feel that a mix is quick fix for something inadequately built or set up. I do understand some planes just need a mix, don't get me wrong here.

Winfried,
I'm sure it will fly good regardless. It's a beautiful design.
Good luck to you with both your new toys.
Chris
