Not having much luck or flight time...

[Flying_Amp]

Well after rebuilding my 450X and test flying last weekend, we went to the field this evening for a few hours of fun.

First two flights went well,(with some sports flying and mild 3D) then on the third, and again only just into the flight, i was doing the first pass down the runway, and just switched to idle up1 and there was an audible "pop" from the heli, and it went into a slow piro, and semi auto ed onto the runway (grass).

Ran over to check the heli out, and luckily there's no damage other than a slightly bent undercarriage leg

we noticed straight away that the swash was remaining in full down elev, even when level. disconnected the batt, and again it still returned to full down. rebound the heli and it responed normally.

Checked all the usual stuff li-po at 12.2v no damage to the head, tail, boom, motor, esc responds.

We powered her up again, and i spooled the heli up to just below take off speed, all was fine

checked everything again, nothing found...
so i decided to take off and put her in a hover over the long grass... hovered for 4 mins, checked all flight controls responded as they should

I am at a total loss, only had this heli around 6 wks, lost it for a fortnight when the AR7200BX failed (proven by HH) and now another weird fault!

Really feel like slinging it in the bin at the moment, lol and there's my buddy go two of them that have never missed a beat.

Ah well!
