Great video Lee. I just finished wiring up my fixed wing with a flight controller, airspeed indicator, GPS, and lidar rangefinder. I'm hoping to dial in auto landings once I get it all tested and tuned. Your videos have been really helpful in getting me started.
Hi Lee,, Merry New Year.. Some good tips for new builders. EMI is one of the major issues that unlearned hobbyist have with RC devices. Proper engineering practice, as you have stated, is to NOT run signal wires in parallel with power cabling, Especially the motor side of the ESC or in close proximity to the TX. 2 things that will greatly reduce these issues is Screening and Grounding. If you have no choice but to run these cables together then either wrap the low voltage signal cables in alfoil (Aluminium foil) and connect the foil to -ve DC or use screened (Shielded) cable with the screen connected to -ve DC. Also do not fly near any HT power lines, communication towers or military installations...
Twist your video wires when you install them to help prevent video noise. Also, I would not recommend installing anything in the canopies/covers as shown. It’s seems smart until you work on the model, or when the cover gets ripped off. Thanks for the video. Happy New Year.
It's a fantastic video! This is always useful for me to build RC model. When especially I build a scale model, I install them very very hard. Though recently I rebuilt FliteTest Sea Angel to change to FPV airplane, the CG balance was not well.
A common rule in structured cabling, if you need to cross ethernet past 240V do it at 90 degrees. I wonder if that rule would apply for RC power vs signal wires..Which makes me think if you needed to to run in parallel would wrapping the wires around each other eliminate or reduce the crosstalk (this is why inside strands in ethernet cables are twisted in pairs.)
: Hi Simon, I recommend to never do what you have suggested. Communications cables are low voltage high frequency and are twisted in pairs to reduce signal loss. "Common Mode Rejection" is the correct terminology if you wish to find out more.
Another fantastic video. Fortuitous timing, since I'm currently trying to lay out the electronics in my first build. Do you have any pointers on how to secure the battery?
