I actually can't get it to break same as rv10flyer stated its a rocking horse ride and you loose just altitude. I guess I will have to move the cg backwards to produce a stall break. The controls were at the backward stop. I will slowly move the c.g. back.

The time spent provisioning and setting this up all takes away from your building. I for one will be present. I hope we can both add flying RVs to the show next year.

I certainly agree with approaching that slowly to avoid any nasty surprises. It is likely useful to know how differently the plane handles stall at forward and aft c.g. limits. I've heard that if one fully explores the c.g. envelope and checks all the other flight characteristics and airspeeds that you will use up most or all of the 40 hours.

I saw little difference between reflex and 0 deg flaps. Dont remember exactly but maybe 2 knots or so. Stall at about 2500 lb was at low sixties. You might want to also verify your weight and cg calculations prior to your next flight.

My experience with birds down low in slow movers agrees with your conclusions. I used to do a fair amount of ridge running in gliders; <500' @ 130-150knots. Lot's of birds down there, especially this time of year during the migration. Years of talking and reading about these conflicts led to the same two conclusions; birds will fold and go down, and pulling up to over them is the best way to avoid them. More specifically, we would often find ourselves coming up in a bird's sixes and at the same altitude or lower. Lateral deviations with 50'+ of glider wing is sluggish at best. The thing we learned never to do was to attempt going under the bird, even if it was 10' to 20' above you. At near treetop altitudes on the ridge, the bird folds and heads for the tree tops. Absolutely every time. Pulling up was the way to go and one would usually just manage to see the bird fold and split S before the nose covered him up. Some learned the hard way and landed with bloody cockpits. However, at higher altitudes my experience (and I think the experience of others) was that birds were likely to do just about anything. In slow speed gaggles when sharing the air with them, they just played see and avoid just as we would. If surprised, the same thing. That is, they would just react with some quick move that seemed right to them at the moment. My personal thinking and plan for action at altitude in an airplane is to quickly react laterally, towards it's tail if possible, and to pull. Pull unless the bird is above me. In any case, given my aircraft and skills, I'm going to go wherever I think the bird won't but it will always be a pull and never a push.

It seams like a big leaky hole to me. Does anyone have pictures... or wonderfully descriptive words... of that area?

Seal it with rtv and seal material as best as you can. Keep fiberglass cutout snug except for control arm area. Think of cowl movement locking prop control up. I have everything else tight and no overheating(over 400F for me) at full gross 120 kt climbout on a 100F day. -------- Wayne G.
