Sounds like too much rotor pitch, that's causing the rpm to drop & low rpm lets the blades flap too much. Lower the collective after you take off & gain speed...
Try looking at the Carter Copter available here by Mark Fisher - he's also got a POH that tells you how to fly it, it's not like any other gyro or helicopter out there.

Thanks all. and thank Jay Carter.

BTW, the rotor is SUPPOSED to slow down - that's what high-Mu flight means! In high Mu flight, it is sensitive to rotor flapping. You can reduce pitch and fool with the "rotor trim" control - and "steer small" at all times.

BTW2: if you're caught in high-Mu flight at low altitude, you can hit the pre-rotate in flight to spin the rotor up for landing. I'm sure they've never done it in the real thing, but the empennage stabilizes the torque, and it works well.

Thanks Brett for the explanation.  I thought there was something wrong with it.  Another thing I noticed after I posted is that my rotor keeps slowing down and I get the flapper warning constantly.  Is this normal?

[slydon56]

Downloaded Mark's copter.  This one I can fly.  I think there is something wrong with the default one.  I keep getting the flapping warning.  This one does not do that so far.   It is a fun little plane to fly.

The Carter Copter is setup in X-Plane with automatic mixture & fly by wire throttle control (look under engine specs 1 menu)- it'll do a better job than you're able to at keeping the mixture set for best power

Hmmm... Maybe Mark's pulled the POH, but the actual aircraft download should also have a copy with it, you might want to give it a shot.

I have been messing with the carter copter lately and found that I can't adjust the fuel mixture .  All my other planes work very smooth.  It seems like I am not achieving top rpm because the lever is at 3/4 and cannot be moved.  I have replaced it and it still won't move.  Any ideas?

[slydon56]

Ok I will read about the one you suggest.  The strange thing about what was happening to me is that I had the collective shut off completely and it still happened.  Anyway I will read it.  Thanks again.     Can't find it.  Link please?     Found it but the page could not be displayed.

Sounds like you have good luck with it.  My problem was that I had moved the collective all the way to zero and I was still getting the flapping warning.  I am going to try again and see what happens.  Thanks for the help.

NB: In my model, zero pitch is NOT at the top of the slider! It is at the top of the green sector. Use the EFIS to get an accurate reading.

And "steer small." That means NO "crank and bank."
