Wow! We need to get another flying day like Saturday! Even with family in town I was able to sneek out to the field for a couple of hours to tune and trim the New Extra 300. Once the CG was acceptable these were the improvements in flying characteristics immediately apparent over the former 28% LX version:
1. Harriers are rock solid. I only experienced wing rock when I was turning cross wind and wasn't on the aileron correction, into or downwind required NO AILERON correction. Inverted was as locked in as upright. Steering with rudder and partial 3D elevator this new extra will be the plane that allows me to comfortably get "down on the deck" within the first few gallons of gasoline! This plane instills confidence not unlike a foamy.
2. Ailerons are about TWICE as effective as the LX. The tapered ailerons give a very desireable amount of control while in slow speed - post stall - flight. While hovering I can do an anti-torque roll with only half deflection of 3D rate ailerons.
3. High alpha knife edge is more easily controlled with the redesigned tail group. This aircraft is less scale with the horizontal stablilizer moved forward but there is intuitive and immediately inherent control of post stall flight, even while flying in the sensitive high-alpha knife edge flight envelope.
4. Waterfalls and Knife Edge Spins are EXTREMELY tight! Wow is all I can say about how tight the spins are while performing these manuevers. With the CG at the point that makes the plane maintain a 45 degree upline, the tumbling characteristics are still phenomenal. Using full 3D elevator and rudder with only a little aileron required, the knife edge spin was a blur. Way more impressive than the LX. Waterfalls flip the plane around its CG like a rag doll. If I do them starting into or downwind I can just bang the elevator over to full throw and watch it flip, almost in place.
5. Coupling Before ANY trimming, other than CG and one "beep" of down elevator, the plane does have some coupling that will have to be evaluated and corrected during the dynamic flight trimming process. Because of the tiny amount of down elevator that has to be added to make this plane fly level an aggrevated pull to the belly during knife edge flight is to be expected.
a. In flat turns there is a noticeable down pitching force, as well as a slight same direction roll tendency.
b. Downlines require a breath of down elevator to keep them straight down.
c. Dynamic lateral balancing has checked out as "balanced." Flying straight down at idle for a few seconds, then pulling out at a fairly aggressive rate - no aileron input - showed
neither wing dropping at all
d. On more than half throttle up-lines right rudder was required to keep the plane flying straight up. I am going to leave the thrust where it is and use a throttle-to-rudder mix when I
get to that step in the trimming sequence.
e. Flying inverted requires a just little down elevator to keep it level, confirming the CG is in a comfortable spot.
f. Snaps are a little sluggish, but that is to be expected with the more rounded leading edge which makes this plane excell in 3D flight and as a first gasser!
g. Aileron differential will be necessary, but without following the trimming sequence it is difficult to say how much will be required.
Let's get started!

I'll report back tomorrow as to whether or not this carb plate fixes the pressure problem.
