Yep. The 2nd flight was a nose up, started rigth roll, throttle back, land hard. All I could do was watch as he flew it. Then we would talk some more about *** happened. Will look more closely at the repairs needed, maybe try one more time. Need to figure out how to repair the fuse IF I get hte rest of it fixed.

What was the first flight like??? Did you have a head wind?

Your description of second flight is indication of just not enough head speed and a too-soon application of up cyclic & elevator that didn't help the head speed. If she did break ground, an immediate application of left rudder would have leveled the Whopper and more than likely the head speed would have increased enough to allow a climb-out. Without addiquate headspeed, cyclic roll just isn't there for a rapid leveling.

Did ya find the broken out fuse pieces? Fuse is made from PVC and can be best glued with PVC "water thin" solvent. PVC clear pipe cement can be used, but sparingly as it's slower to evaporate and will soften the rigid pvc till it does evaporate.

To reinforce a fuse crack, I'll lay a piece of 3oz. fiberglass behind the crack and apply PVC solvent and let dry. CA can be used but is brittle.

Check the pitch change rods and the swashplate plastic inner ring for damage.
