Looking at adding a 305 or 307 . What are the major upgrades you get with the 307 ( rv8 no yaw damper )
 
The 307 has dedicated knobs on it for heading and altitude, the 305 doesn't. I'd gladly trade you my 305 for a 307 plus cash, if you decide on a 305. The 305 is not quite as tall, which might make a difference on an RV-8 panel.
