Drone not always going where expected... newbie issues :)

So, I'm new at this drone stuff.

Practicing with a SJRC F11 Pro 4K.

I lift off, everything's stable, in GPS mode.

Sometimes I'll try to slowly go forward or backward, and it goes opposite of where I expect it to go. (I'm not in headless mode.)

I'm wondering if I am dealing with wind... which was light... but maybe. If it's stable with me not touching the controls, and then I try to pitch forward slowly, but there's a headwind, does GPS kick off and the wind then push it backwards? So it's not like I'm flying forward based on GPS? (actually, when I started forward slowly the actual drone pitched backwards - maybe the wind catches it? Then when I increased forward on the toggle, it pitched forward and few forward. But made me feel out of control since I pushed it forward and it did the opposite, my reaction was to toggle the opposite way, then it really goes backward!

I've also been going forward at times but the actual track is angled. Wind there too? Normal behavior or something wrong with the drone?

If you think this just sounds like I'm dealing with wind effects, how best to learn to compensate for it? Maybe I just need to fly more aggressively, I am trying to keep it slow right now...

There is a front and a back. If you're not in headless mode then you may be oriented wrong. A lot of quads come with lights on the front or the back. The User Guide will usually explain this. Learn which are which. If you toggle forward, the quad will go in that direction. You would soon learn which is front and which is back. So, you need to figure your orientation if you are not flying in headless mode. Wind is a factor. Air flow at ground level may be slight. At 50 feet above the trees, it can be a howling cyclone. LOS flying is what it is,.
 


Both of these are a little old and neither is perfect since teachers always just staying one lesson ahead :D but good advise and tips I wouldn't think of when trying to get going at first. Throttle management tends to be hard if things are drifting a lot you might have some accelerometer calibration or other stuff to deal with but it does take some stick time to get in any sort of control when doing more manual flight (not relying entirely on sensors and gps for more automated flight control).
 
I'm sure insulting your intelligence is not the intent here. Our members are a helpful group. Not knowing your level of expertise, we suggest these videos to help you understand the nuances of flying these four rotored pigs.
 
No insult taken :) Rank beginner, been out for about 5 flights so far :) Yesterday's flight was better. I think part of the issue was just being in camera mode, once I bumped it up to regular mode it seemed like I had more control.
 
Once you get a few more flight hours in, just take it easy for a while, figure out how the different modes react
throttle control for me, in a bird without altitude hold, is a real bugger, my Bug3 is like a yo-yo, still working on it.

I always take another quad with me when I take the Bugs out, just to get some flight time in and practice warm up before flying the Bugs out and bouncing it around in the grass,,,,,,,,
Going to try 3 bladed props today to see if that might tame it down, they have less pitch than the stock twin blades do.

BTW, love both video's,,,,,,,,,
 
And a lower pitch should yield slower response, I might try to add a return spring or a set of centering springs to the throttle, I had the transmitter apart after my first flight to see if I might be able to put some kind of resistance in the throttle lever, I mean if I just bump it a bit it's gone,,,,,,

Could be I'm too old and too new to flying that I may never quite get the hang of no altitude hold.

Could also be that the throttle stick is too loose, nothing actually loose inside but just too easy to move.

think I'll have another go at getting the throttle stick to stick,,,,,,,,,

I guess I'm wanting to be able to fly it, it's fast & nimble, and after my former Potensic 85 did it's flyaway I ended up with 6 extra batteries for the Bugs,
I thought perhaps of getting the Bugs 3H, but none to be had,

I'm thinking of using the joystick out of the P-85 transmitter, and swapping it for the one in the Bugs Tx.

It's in the garage somewhere, least I could dig it out and try something,,,,,,

Could the Potensic Tx bind with the Bugs?

Hey not sure about the binding but if using betaflight on an FC you can pretty easily adjust the "throttle curve" or how much actual throttle is output given some input (can make it on linear so you have to jack the stick way up to get into the actual top end of the power). I'm not familiar with bugs or really any off the shelf stuff but any betaflight based quad you can fine tune the expo/super rates and throttle expo/rate. That said also most transmitters based on openTX will have gimbals or sticks that have two adjustment screws on the back for adjusting "clickiness" or smooth resistance.
 
Appreciate your reply, just took the tx apart, no adjustments, also no trim for throttle like on other Alt hold Tx's, the Alt hold in the Bugs 3h is only a centering spring for the throttle stick, I can do the same thing with a rubber band around it, may even be what I do anyway.

I put a bid in on a 3h on ebay, but it's low enough if he accepts that I'll have a tx for both 3 & 3h, with the centering throttle,

Ok I've hyjacked this thread long enough,

Thanks again for the input guy's.
 
The guys flying RC helicopters if they have the same problem with throttle they learn to fly pinch mode , thumb and finger flying , I tried it felt to slow to me so I fly thumbs , but they do say control is better with pinch and most fly 3D with pinch mode
