  • Harry the butterbeer swilling T-rex.

    Been out with Harry again lunchtime. No highspeed insect pursuits (although I see more blood on my blades so maybe the insects didn't get the memo).

    15 more minutes of video (don't panic, don't panic - push this button instead - I won't be putting them up). I'm going to edit them down to best and worst moments. I had a couple of narrow squeaks and it would be good for other learners to see that a narrow squeak can become nothing more than momentarily held breath as you recover the heli inches from the beep-beep ground

    Anyway, the main point is, I was watching the butterbeer swilling Harry and noticed that when he pointed into the wind at a certain angle his tail would drop - and would have continued to do so had I not compensated (this is with AR7200BX). I thought it was BX cyclic trim at first but I turned him round to see. 180 degrees round and the tail did not want to drop but the nose did ever so slightly but didn't go all out for it like the tail droop.

    Turned him 90 degrees and noticed that he wanted to tilt, say, to his right (wind on his left). This, I take it, is normal and something we just learn to live with and compensate for? Was I naive to think that the heli would just get pushed along on the wind upright?

    I have had an inkling this is normal because when nipping along in FFF with the wind coming at a heli's side one has to gently correct all the time to keep the path straight. This is normal to I believe.

    What interesting creatures our helis are. To fly they need nursemaiding. And why not I say Might recheck my CoG though, just to be sure. Especially as my cable arrived today so I can extend the ESC leads so I can have battery cable pointing down when in the holder.

    Thanks.

    Vikki.

    I think my BX based heli has similar characteristics ... clearly the wind will affect the disc as you orientate around the axis ... i just get used to it ... not sure it can be dialed out unless its something to do with cyclic gain or other setting...

      Pretty much what I thought. Worthwhile experiment

        Come to think of it, Harry is doing what the flybarred Chopasaurus was doing but a lot slower.
