Attitude and GPS sudden ascent

[kloner]

so is this something your flipping back and forth when your flying? most people never even go into manual. i use it to take off clean then flip to atti and fly, land, turn it off, flip it to manual before i take off again. meaning, if i am dealing with it by flying not the way i'm setup, it happens once every 10+ minute flight, and just when i'm taking off, like in a real plane putting up the landing gear and flaps

even if you change to larger but same kv motors and keep flying 3s, it is going to do the same thing. if you bump up the motors kv, and keep 3s, it'll fix the problem. if you switch to 4s and keep similar kv it'll fix the problem. This is assuming you setup the radio right

have you got it hovering in manual and looked down at your throttle position? it's probably over half way? What happens when the throttle is over half way in atti, it goes up. i'm not understanding why your trying to fix it using a different 3s then trippin out? if it is hovering at half throttle in manual and your hitting atti and this is happening, you didn't put your throttle to midstick when you clicked finish doing the calibration in assistant

Oh this makes sense. I'll try to recalibrate the sticks again then. Yes, in manual I'm a little over half stick when I'm in a hover. I guess you are saying I should recalibrate the sticks.

I didn't think I was "flipping out", I'm sorry if I came across this way. I really do appreciate your assistance and advice, you have been extremely patient. I was just trying to get it near perfect cause I like to fly FPV. I also like to fly in manual because i have, what I perceive as, greater control. It feels more like a FBL heli in manual, something I'm used to. Attitude seems a little too tame for me, but that being said, I like the fact I can let go of the stick when in attitude and the craft will just level off again.

Getting back to the stick calibration in the assistant; You are saying I should leave the throttle sick at mid way or just above midway when I'm done and hit finish? This will make the manual stick more similar to the attitude stick? That makes sense to me. I guess it was strange for me because I didn't have this kind of lift with the stock props on, this showed up after I installed the Graupners.

I really do appreciate your assistance and patients.

I guess i'm getting at i bet half the naza flamewheels out there do this and not many people care. i dunno. flew helis for 12 years, i prefer the atti mode but that's me however everytime i take off is in manual so the gyros don't try throwing me on the ground from getting hung up on anything. To really nail this you need a way to monitor your current, otherwise your guessing, but i can guess pretty good

usually if the craft is propped/powered right, your goal is to make it hover at half stick in manual. if it does what your saying yours does, it needs more lift in manual. ways to get that, bigger prop or more volts so it can spin faster or motors with higher kv. When the craft does hover at half stick in manual, flipping to atti is seamless cause half stick in atti is hold altitude. if you hover at 2/3 throttle and hit atti, the craft is going to rise, like it is designed to is how i know. more than half stick in atti means up.

So all that said, a regular old out of the box nothing been put on hex should do 8" on 4s or 10" on 3s. Add anything and all that changes. 100 grams, 200 grams, next thing you know it's got a half pound on it and everything is different. kinda part of the problem with the dji arfs, there good to go just like that and that only. will it carry more weight and fly, you bet, like yours

I think I can learn to enjoy flying in attitude mode, certainly seems safer.

Just for fun;

yea, so that's why the going up when you switched.

If you set it to mid stick, do the assistant calibration, hit finish, you could correct it with the throttle curve easily. does your radio have that?

Yes my radio can do T-curve. It's the Aurora 9.
I tried moving the throttle curve up before but it made little to no difference. I set my mid-stick in manual from 50% to 64% in the T-curve, but it sill rose when I went into Attitude. I can try and recalibrate again but I already did that a little while ago and it still rose. In your opinion, should I try recalibrating and try leaving the throttle a little above or a little below the midway when I click finish?

At least I now really understand what Attitude is doing to my throttle stick. My stick is a little over mid-stick so when I go into Attitude the Naza is interpreting that as fly up until I go back to mid stick. I didn't really get that before.

when you make throttle curves, there usually associated with the f mode switch, top front left. just changing the throttle curve across manual and atti won't fix it, you have to make manual 65% and atti 50%. you'd have to make the f mode switch control both the throttle curve and atti/manual. otherwise yea, no difference.

That's what I did. Manual has one T-curve and Attitude/GPS have there own T-curve.

not sure why it didn't work that much last time, but this time the change to the T-curve helped. The rest, I can live with. Thanks kloner for all the help. I can live with it now that I understand it and I think I can like flying in attitude.
