As I stated before I balanced mine with empty tank, it flew fine when I landed it had about 1/4 tank left. I agree on the control movements pitch is very sensitve. I have a lot of Expo dialed into mine. As far as nose weight to balance I put in a nose gear retract so I had to use a samll piece of lead in the nose of my EZ. Also had to beef up the plywood platform where the battery and weight are attached.

I got on some web sites that talked about the full scale EZ and found it was supposed to sit slightly nose hi at normal take off weight. If it sat nose down the take off roll was dramaticly increased. Mine sits slightly nose high and I just hold some up until it lifts off on its own. I saw no bad tendency's in flight, just that it needed some up trim. When I landed it seems that the elevator is ever so slightly down at the trailing edge from what would be flat with the bottom of the canard. As for the ailerons I have them on seperate channels so i can dial in differetial aileron and if needed to adjust them to solve any bad trim in the pitch axis. I haven't tried any pitch changes yet but I like the differential aileron. Mine moves up about 1/2 in and down about 1/4 in. It rolls like it's on a string, and is not to fast a roll rate. I agree that the trim on the bottom of the wings should be removed. It is hard enough to get used to the canard silhouette, and an all white bottom helps a lot.

I want to replace the chrome rod across the rear of the plane with a carbonfibre one that should weigh less. I have even thought of just threading a small screw into the hole as it's only purpose is to keep the wing from rotating. I would guess the 4 nylon bolts will do the same thing.
It's probably not even needed.

The cowl definatly needs some airflow improvement. I may just build a scoop and attatch it to the wing. The OS46 doesnt stick out enough to get a good flow over the head. Maybe some other engine may. I almost put a Saito 80 4 Stroke on mine. I'll just fly without the cowl for a while. I'm turning an 11x6 APC pusher prop and have seen no problems with hitting the ground. If it gets in anattitiude high enough to strike the prop its already beyond the stall pitch anyway, and is going have more problems than a broken prop that close to the ground.
