Default Spoilers/flaps

First of all, spoilers decrease the incidence of the wing to the fuse and to the horizontal stab. I have not used spoilers in a split aileron (4) configuration, but I do use them on funfly planes with full length ailerons. There is a big difference in the effect flaps and spoilerons have on a wing, whether they are full length control surfaces (extend all the way to tips) or if they are just inboard control surfaces (from root to about half way out). A wings incidence and angle of attack to the "felt" air velocity at the tip, often makes a big different in when and how quick that tip will stall and snap. I almost always use full length spoilerons for Elevators and Harriers, and it can be fun to make a steep decent with spoilerons on.
I really can't answer your question. If you have split ailerons and want to do the crow, you should run flaps on the inside and spoiler on the outside. If you do it the other way, your wingtip is more likely to stall and snap.
