RE: Setup Tips for your MCPX

Thanks for the welcome, and also the tips. You've given me some good things to try.
<div></div>I'd already decided to paint those linkages some bright colours like red and yellow, butI have to wait until my husband goes up town shopping again to get some paint as we don't have any and wasn't sure what kind to use.I guess the sort of little tins of paint they sell for painting models would stick to this kind of plastic, wouldn't it? Hubby will have to do the painting too, asI'm chemically sensitive/chemically injured from exposure to builders' adhesive, soI can't go near anything with chemical solvents.

I'm glad to hear that fishing line is all right to use; what with these rotors being so lightweight, high speed and delicately balanced,I was worried that anythingI attached to the mechanisms might affect the handling, which is touchy enough as it is.

Re spooling up,I thought you had to do it fairly quickly at first so as to gain some height and leave the prop wash behind before you could expect stable hovering, which is whatI've learned to do in myX-Plane flight sim (though in the sim it's pitch and yaw, at least until I've set the yaw trim, rather than pitch and roll, as would be needed to stop the mCPX falling over sideways). The bloke at e-Flite who designed the mCPX demonstrated himself onYouTube how you should get away from the prop wash pretty sharpish before trying to hover, and that's whatI've been trying to do … maybe trying too hard ...

So are you saying thatI can take it more slowly and gently, regardless of prop wash? And also thateven to go straight up and hover,I need to be jockeying both sticks,i.e. correcting pitch and roll as well as pushing up the throttle/collective ... just to get it to hover?I have to do that when flying helis inX-Plane on my Mac or iPhone (though in the sim it's pitch and yaw, not pitch and roll), butI didn't reckon a model heli would need such sophisticated handling, even the mCPX …

Re setting things up the wayI'm comfortable with them,I don't even know what half of them are, 'expo' included. Also Swash Type, Swash Mix, Mix 1, Mix 2, D/R Combi, Modulation Type, D/R & Expo, Travel Adjust, Gyro, Differential, Revolution Mix; it was all balsa wood, tissue paper, dope, Stanley knives and glue, or strong plastic, strong string and a tiny petrol engine whenI was a tomboy making models in the seventies. Various electric guitars, fast dirt and road bikes etc., have taken up my time since then, my last few being a Husqvarna WR125 Enduro, a Yammy TZR250 ( both sweet-handling, racing 2-strokes :^D ) for everyday use and a Ducati 750 Sport for touring. But now I'm too ill to ride bikes any more,I've come full circle back to models again.

Ahem … anyhoo, I set the DX6i to the standard settings for a mCPX, butI can't 'tame' it for indoor use or tinker with the settings untilI know what they're supposed to do. IfI could fly it properly already, that would be different; but as it still finds a different way to crash every timeI fly it, the 'try it and see what difference it makes' method isn't going to work.I'm mechanically minded, trained as a TV technician (analogue electronics) and good with my hands, but this digital element in models is all new to me. The Spektrum DX6i manual assumes prior knowledge, so reading that hasn't helped. Any links to pages where all this stuff is explained to beginners would be very much appreciated, asI haven't had much luck with Google so far.

Cheers,

Lachlan
