Trouble getting 0 pitch

Got an HK-450 and whilst I am getting better at hovering, for some reason I cant seem to get 0 pitch set at middle stick, in effect I am cheating a little and hovering below mid stick.

Despite using a pitch gauge showing it is 0 degrees at mid stick the heli lifts off before getting to mid. It is lifting off at around 1/4 - 1/3, any suggestions, perhaps I am not using the pitch gauge 100% correct.

cheers.

maybe not .. just set the flybar level and sight the end of the blade when the stick is at the midpoint .. the blade should look level whilst comparing to the flybar ... my experience has been you can eye-gauge it to within 1/2 a degree or so of zero. you should have the swash level (ie square with the mainshaft) for this exercise

Turn on throttle hold and set your stick to the middle. fold your blades back like they were going into the blade holder. Rotate the blades to the front of the helicopter and then pick up the helicopter from the tail shaft and hold it hanging nose down. If the blades are at zero pitch, they will hang exactly the same way.


Zero pitch


Not zero pitch.

Try to hang the heli so the flybar and the tail boom are parallel for best results.

You can look at my DX7 setup guide in my blog. Just click my name. Your radio may be different but the principles are the same.

I have got a Dx7 as well.

Oh well , just went for a fly at the local oval and was flying well, big gust of wind came and picked it up and I lost orientation, into the ground she went.

Busted teeth on the main gear, bent tail, bent blade shaft a few other bits and pieces bent. Oh well back to the online store

it's not like the pitch gauges are precision instruments anyway.

more like an eyeballing assist
