Hi, I am a noob and alot to learn. I did what most do with a bit of bucks and bought an RTF to learn on and here the fun starts. I found a RTF system in South Africa from Steadi-drones using the X1 frame and heard countless times how steadidrones as he claimed to know "as I know what this involves more than perhaps anyone is SA." and it wasn't cheap.
My first question is about APM1 controller mounting ( see attached photos):
1. How accurate can the controller be if it is mounted in foam instead of a fixed bracket?
For example if I level it and then fly - surely the board can move around a bit - especially in wind - which can explain some unnecessary yaw, and pitch movements as the gyros are not fixed, but in fact moving?
I am new so don't know if this is normal.
2. How can I tell if something is well soldered - see image, and is there a chance that this can effect the setup. Is it good practice to use tape instead of shrink wrap?
Thanks all for your help.
The solder joint looks ok. It's always hard to tell, but if the solder beads up on the surface rather than flowing onto the surface you have a problem. A bad joint is basically a resistor and will heat up. See youtube for some great soldering tutorials. it will be 10 minutes well spent learning about flux and oxidation, etc.
The Foam looks fine. You should make sure your motors are all straight or you will get odd Yaw effects. Tuning also helps. The ATT message in the flash logs is great for tuning.
The next release of SW, coming this week has some stability fixes deep in the IMU/AHRS core that will help a lot. Look for that.
Thanks for the very quick reply.
Its not stable at the moment so am going to test the motors in the CLI.
Am running 2.4.1
I did the CLI motor test and cycled about 20 times, and consistantly two motors spin fine, but the other two intermittantly do a little shudder about twice, and then return to normal on the next or second cycle before doing it again. Could this be a bad connection?
