Brian,

I flew Dave L's contar equipped Bravo last year and absolutely loved the way that plane felt. I told Dave it is one ofthe best if not the best model I have ever flown.

It has "fences" on the stab and wing and a ventralstrake that starts at around the cg and goes to the tail post. Although the model has about 50% the area of the fin-rudder included in the "fences" and ventral fin, it felt just sensitive enough in yaw; ie-well damped but with enough authority to react NOW! Nothing goofy on Dave's rudder either

I think that the contra equippedvertical stabsneed to be considerably larger than the current crop. Maybe as large as +25%, but maintaining rudders fairly close to today's sizes. Maybe one way is to add ventral area while maintaining the dorsal side as is today
