ArduCopter Failing with Althold/stabilize

HI,

Been flying twice now and both times my copter dipped. 1)flight had altHold on and had to put more throttle to get more up, then switched to stabilize back and it dipped. FIxed the copter and today went back 2) flight Stabilize, flew well, when put to Loiter, it was very wierd, then after like 5 sec, just dipped. Tried to switch back to Stabilize but I guess too late. Could be something wrong with flight controller or GPS? Or something else?

Setup:

APM 2.6
ESCs: 4kpl TURNIGY Plush 60amp Speed Controller w/BEC
Engines 4kpl DualSky XM5015TE-3, 700W
Props: hiilikuitu 4kpl 15x5.5
Tarot T2D gimbal w/gyro
2x 10 000mah 4s akkua.

It is little overpowered, but B/c i want to carry maybe at some point some heavier stuff with it.

Thanks for all the support!

  • Sorry hoped I was the only one with issues I've been fighting my APM 2.6 for almost 2 years. After a couple of months I bought a cc3d flew great but no GPS. Started messing with the APM again had a couple of ok flights then had the dipping as you said took off straight for the sky like it originally when I first put it on. Had to kill it with the failsafe crashed broke my main part of quarter frame including distributionboard.. after lots of stress and frustration lots of money and wasted vacations I got no video to show for I finally gave up and went with DJ I even though I said I'd never would have seen people with Phantoms and they're phenomenal. I really really wanted this to work out it started off to be cheap but cost me well over $1,000 in broken parts to finally say this thing will never work right
    • sorry to hear! Yeah, same thing I've put well over 1000 into it as well, probably closer to 2000 now :). Thinking of buying RTF now. it's a pity because it flew and worked well few flights, but learned a lot from it though.But it's weird since working perfect on stabilize mode.

      I had same kind of issue on first flight that you had. but it was due to fact that I had put Return to home flight mode mistakenly on even though It was suppose to be alt hold. Then it shoot up, and I got scared and killed it. Afterwards noticed that Return to home and should've just let it go.

      But yeah, maybe have to go with RTF as well, like SOLO or something. I think i'll update to Pixhawk2 when it comes, might be that FC is damaged (but again then it should give an error)
