By adding the up thrust I got rid of the "ballooning" and now the downlines are good also. I would think that by adding the +.5 deg. incidence it would add to the ballooning effect? Wouldn't you go with negative incidence?
What Speedracer stated is pretty much on the mark. Trimming the model for aerobatic flight is the key and it isn't magic, it's just work we all do as a matter of course. If you understand terms such as MAC, you may want to investigate how the model performs with CG located at various percent of MAC. A typical start point is 25%MAC and working rearward from there. I would not go more than about 35%MAC tho....too many other compromises, even tho the model willl appear to fly okay.
The nose overs are caused by wrong placement of the landing gear. Moving the gear forward 3" (if it's possible) will cure the nose overs.
To the OP, have you guys looked at the Extreme Flight Extras, Yaks and such? EF sells some really nice, well thought out and built models. These tend to be lightweight for their size and pretty strong. The weakest part may be their landing gear blocks but on the larger models these have aluminum angle reinforcements. They will still break but it takes work.
