So the second method came in, I took out one of my top and bottom gimbal plates, mounted everything on top (with gel pad) the vibration reduced a lot but still not working. I can not hold position and altitude in Loiter and Alt-hold at all.

The first method that i tried is to mount it on gel pad (the green gel) which was quite good for 750kv but when i moved to 900kv, it seems to me that there is more and more problem. Right now i'm facing another problem is vibration I have tried my best to find a suitable way to reduce it as much as i can but non seem to work.

Everything must be perfect in order to archive the best. P/s: Big thanks to SeanM and Big_Island_Guy for supporting me from the beginning.īuild a pixhawk is really a lot of work, from choosing the right motors to the right escs. I will try to keep this post as up-to-date as I can, but as i'm currently working 2 jobs to earn enough money for my wedding so please excuse any mistake that i made.Īlso my english is rubbish, it is not my first language so Grammar Nazi please fly away My compassmot is about 27% which is not too bad for my design, but i'm looking for a way to reduce this to below 20%. When you do your calibration, please remember to place your TBS Discovery with Pixhawk on a flat surface.ġ4. It seems to me that my Pixhawk is having sync problem with TBS ESC and motors. I have mounted my Pixhawk above a top place of a go pro gimbal (I will give you guys a picture of my setup so you can have a better ideal of what i'm talking about).ġ2. I found that if the Compass is being placed above all motors, everything function better.ġ1. (I did my calibration in the room without any electronic interference, not 100% but there is only my laptop in the room )ĩ.The battery is really heavy as I have a Gimbal at front, so it countered the weight but the whole quad is too heavy, I have to set my MID_Throttle is 680.ġ0. Compass calibration must be done carefully as it is the main problem that lead to crash, flip, etc. I don't know what is the main reason behind this, maybe because I was the lucky one.Ĩ. but it seems to me that 750kv is way better. They said it has better bearing quality etc. Almost 99% of people who goes for the TBS motors for such setup will choose 900kv instead of 750kv. The 750kv TBS motors seems to work much better than 900kv on 9x5 propellers which surprise me the most. I have look all over the place for a solution for such problem but it seems that the DJI arms are quite flexible and that is what cause the Z axis to jump all over the place. Vibration is our enemy, my X and Y axis is within the range but my Z axis is sometime when over the -5 to -15 range. SeanM PID is really good as baseline, but you can also try Autotune function. I'm having a tough time calibrating the ESC right now, it seem to me that the Pixhawk or ESC won't save the throttle range.ĥ. You must remember to calibrate the ESC.Ģ. TBS ESC is not pre-calibrated like they said on.

I'm pretty sure that there is more, but I will have to update later on. 3DR telemetry, MinimOSD, Power module, etc. TBS Motors 900kv v2 (I have also tested them with 750kv)Ĩ. TBS Discovery V1.3 (50A current sensor)Ĥ. So the below is my process of building with a list of items and I will post every mistakes that I have made so that you guys won't make the same mistake like me and happy flyingġ. Please note that when I first started this build, I have always followed SeanM's build and other well-know TBS builders in several forums so that my build is somehow a mix style of all. so that we can share our problems and probably find a good solution to all of them. I will try to keep you guys up-to-date with all the building and problems that I'm currently facing. I'm in the process of building my TBS Discovery /w Pixhawk so I started this thread to share my experiences and hopefully help others as well.
