I have a 3dr quad and was thinking of buying upgrades to get it to the hexa.  Are the hexa's more stable and little better to fly?  I was looking for some pros and cons.

Ditto on the same setup, 3DR Hexa-B, 11X4.7. I encountered the same clearance issue between two of the props. What worked for me was to loosen the two arms slightly, shift them apart, and re-tighten.

This is the same set up as I have and the 11x4.7 fit fine on mine. You may want to reach out to 3dr or udrones and ask them what is up. It would be nice if they provided some type of guide for the set up even when they are RTF but i guess thank goodness for the community.

Andrew. Looks like you have a big problem. I am not sure if 3DR frames are designed for big motors and big propellers but way how they are in your hexa is bad and you cannot use it like that. all jDrones frames are fully tested with 12" propellers. I would suggest to use only 10" props on that your current hexa.

Hello.. Shiny new hexa with all the toys about to leave bench (I hope).. however prop clearance issue! Or am I missing something.. 880 motors 11x4.7 props
