Gaui Advise on flying a Gaui 330 XS

[phenoman]

Hello

I am struggling to fly a Gaui 330 XS quad. I have the protection frame on the outside (essential if your a learner) which I am very much! I am having trouble just getting it off the ground. It keeps tilting violently on each side when any throttle is applied. I have at the moment the extended legs on the bottom and also the one axis camera mount as well. This provides more weight which I thought could make it easier. The Simulator allowed me to fly it perfectly, but its like starting again with the real thing! Any help would be appreciated with it, if someone has experienced the same problems. I have the DX6 Spectrum transmitter and I am adjusting the rudder and gthjrottle controls all the time.

Many thanks

Have you had it flying at all? If it just flips on take off then;
Check wiring to motors is as it should be, check esc and Rx wires are all as per manual.
check direction of rotation of all motors is as per manual, check your A and B props are where they should be.
These things should just lift nicely with no Tx input at all except throttle obviously.
You should take off all the gear you dont need till its flying right.
You may have your GU344 gain set to high or low, about 60% should be good to start then you probably have to down it to about 50%
Probably best to switch HOVER/CRUISE modes with the dip switch on the FC for a start, ie disconnect the green wire from Rx / FC.
Set it to hover first.
When I built mine I followed the manual to the letter and had no problems

If its flying but just not right, it could be the one or more of the booms are misaligned.
Are you connecting the flight battery with the 330 on the level?

Hiya. Thanks for your input. Well its a fully assembled version, so Buzzflyer definitely test flew first before sending it to us. So it can fly, and the props are flying in the correct direction. The wires all seem OK. Not sure what you mean by the GU344 gain? (I am a beginner so its blinding me with science this at the moment) I will see if I can set it to hover mode. I have reduced the throttle which is helping but when you move the Airleon it tends to increase the power to much, which seems to flip it over. Thanks

I have an original 330X and they can be cranky at times. As Bowley mentioned make doubly sure that each motor is connected to the correct port on the GU 344 and that each motor is spinning in the correct direction as well as making sure it has the correct propeller installed. Most of the instances where I've seen the problem you desccribe it has been due to a motor that was either connected to the wrong controller port or not spinning in the correct direction. If you want to post some pictures of the setup it may help us see something you might be missing.

One other thing comes to mind, cruise mode is much more stable than hover mode which may not make sense but it's the reality of the GU344 controller, so if you're trying to fly in hover mode switch to cruise mode and see if it helps.

Hi Ken

Thanks for the information. I have checked its correctly the rotors are rotating in the correct position. I believe you can change the hover and cruise mode with the tiny little switches on the GU344. I will try that. I have just taking it out and its still tilting, but managed to get it bouncing off the ground. Well it did fly briefly! The throttle just seems so extreme once its off the ground. The trick seems to be to keep the Trottle where it is, and adjust the Aileon and it will naturally increase? I will post some pics to show you. Thanks! Stu

Hi Phenoman, I have the 300 xs if you are using the GU-344 i would forget the hover mode side of the flight controller, its not the best and as someone told me its like flying after drinking 5 pints of larger.
when i had issues with me GU-344 i found the best thing to do was go back to base settings and reset the ESC's. if they go out of sync you get all sorts of problems with motors starting at the wrong time etc.
I assume you have the manual if not drop me a PM and i will email you the page on how to set it.
i have quite a few videos on my you tube channel using a standard Gaui 330 xs

hope this helps
Cheers

You may want to add 30% expo to your transmitter on the Aileron and Elevator channels. I think that at one point I was at 50% Expo and 80% D/R to try and calm things down. This will make it less sensitive to control input around the center of the stick. Over control is typically a newbe problem and we have all been there. Sometimes less is more. The Gaui was my first multi rotor and it has been an amazing ride so far. Don't give up! It will all start to become second nature to you with some flight time under your belt. Another suggestion would be to get an mQx. It may help you make the transition from sim to flight easier. Works great indoors and hard to break. I fly mine all the time while watching TV.

I would also suggest trying a 2s Lipo if you are finding throttle very lively .
Running a 2s Lipo will really tame the Gaui 330x-s , Also as others suggest check there is at least 30% expo in both elevator and Aileron for beginner set up.
And make sure the GU-344 is in red mode (cruise) Hover mode does not fly well at all .

Hi Geoff, sorry for my ignorance, but what is a 2s Lipo? It does need taming, as I really didn't expect how lively this little unit can be! I have played around with the trimmers on the throttle and Aileron, which seems to help when the units starts in a lower RPM which provides more time to adjust, however when it tried to take off there seems to be too much throttle. This maybe due to my inexperience, however its very different to the SIM.


Thanks

Hi Mark, I can only dream of flying this unit like these videos! At the moment its seems like its never going to get off the ground! I have looked at the manuals with the ESC's and I cannot see how you reset them? Do you mean unplug them all?

Thanks

Just follow the proceedure in the manual, basically just a calibration ie switch on Tx put throttle fully fwd, connect flight battery listen for the tones and return throttle to zero, thats basically it as I remember, details are in the manual. One thing I noticed with my330 was if I had the gear channel connected ie gyro and switched between hover and cruise with the Tx it would seem more unstable in hover than in cruise. It must be something to do with my gain settings because the opposite was true when I disconnected the channel and used the dip switch to change modes with the correct gain set on the GU344 pot.

Hi phenoman
Not sure if you have the manual but here are the relevant pages for setting up the ESC and GU344.

Hope these help, obviously all pages copyright of Gaui.

The ESCs on the gaui330 have really been my only gripe. Before I learned about re-calibrating them I was experiencing horrible unstable oscillations. If I tried to hover the wobbling would only increase, and this was after adding weight to the arms to increase the rotational inertia, in case it was a harmonic of the rotors. Alas I have found myself needed to re-calibrate the ESCs every couple of flights, but afterwards it flies smooth as can be.
