Question sinking feeling with Huey

Speedbird370,
For whatever reason (RealFlight Ranch is only runway flown so far), the Huey seems to want to sink into the asphalt at idle; easily comes unstuck; and responds to commands; but seems to me to be significantly underpowered, unless this newbie has something wrong in my preflight setup. Perhaps too many 3D choppers has tailored my expectations for more power than I seem to be able to get (with throttle trim centered)?

Thank you for the bird, though.

Yes I have noticed that the skids seem to flatten out when the heli is sitting at idle,
I donít know why it does this and I donít know how to fix it....

Itís no 3D heli thatís for sure and it was never intended to bee one,
the rotor is only spinning at 890 rpm, a little low for 950mm blades I know
but at this rpm it fly very scale like

I made this heli to see if a 1:5.6 scalebodyheli at 19 lb could fly with the power of a 29cc gas engine
and a rotor speed of aprox 900 rpm,
normally these big models are powered by a gas turbine engine that has loads of more power then the 29cc,
but for normal scale flying the 29cc is just enough, not any power reserve though...
