Just a beginner in FPV-flying, if I find time next to my other hobbies (kids, wife, dog, house, 3d-print, fixed-wing, electronics-diy ...).

Thanks for the fast response!

Unfortunatly I don't see the option to upload my own picture. Neither in firefox nor in edge.

My question about the contact-option is obsolete: Now I found the button in the top corner "leave feedback". Must've been blind. Sorry about that.

About PWM-servo-connector: How should I build them? Espacialy if you draw the part from top, the connectors for signal, power and ground are mostly on top of each other (see e.g. Betafpv SuperP).

The PWM-receivers have another "problem": Which pin should be used as power-input? At most PWM there is one rail for power and one for ground. The power-input is from ESC (at ELRS (AETR) mostly ch3 at Spektrum (TEAR) mostly ch1) and provided to the servos.

Another issue that came to my mind: some FC have solder-pads, which have to be bridged, to provide different power-levels (eg. Mateksys H7A3-WING). How to build and label these? See also Mateksys CRSF-PWM-C: has a solder-pad, that has to be bridged, when no extra BEC is used.

The new drone builder is really a great idea.

I made already 3 parts of my drone.

But I'm missing an option to use own photos, to build the parts, because some photos are taken in an angle, but I have some other directly from front and back (mostly found in the manuals).

Also a contact in the drone builder to report bugs, missing functions or suggestions for improvements would be fine (i.e. I tried to build a PWM-receiver, but I didn't found a part to build the servo-connectors).
