HiI am new to UAVs and quadcopters. I am currently working on my first quadcopter and planning the set up.I have a question concerning the balancing of the quadcopter,as I see different set-ups and possibilites;is it better to mount the ESCs around the main electronics (as shown in the ArduCopter wiki http://code.google.com/p/arducopter/wiki/ArduCopter_Electronics) or on the arms (like shown in this specific project http://www.undcon.com/2010/11/14/quadcopter-frame-take-2/)Would it make any difference concerning the stability?thanks a lotFelix

  • This question pops up all the time.

    ESCs in the hub: easier construction, heats the electronics and batteries in winter, more resiliant

    ESCs on the arms: better ESC efficiency (cooling with prop wash), slightly increased smoothness of flight (more mass at arm ends), lighter contruction (instead of three heavy gauge cables you only need to run a single one through the arm), more prone to failure (ESCs are more exposed to the elements and impact damage), harder to construct (you need to attach the ESCs to the arm somehow)
