In my Initial build i was using these motors

However thinking back with my quadcopter i damaged a naza unit when i had a prop driver failure and i have also had problems with this sort of prop driver in the past.
I have used the spare ones i bought and retro fitted them to my quad again now, and also changed out the two esc,s on the side that failed just to be sure.
These were originaly for the hex as i was going to strip the quad, but have since thought otherwise.
Back to the hex build i have decided to fit motors with a proper bolted on prop driver now to at least eliminate this issue, so could any of you guys who fly a tarot give me some suggestions for the type of motors and props that you are using please and also which esc's yours are mated with?
Thanks in advance

go for something about 600 800kv for tarot hex and 40amp esc's or 30.
props will fit 12 13" max.
Here's my spec - flies very well!
I'm runing these http://www.electriflite.co.uk/store17/index.php/popular-items/mn3110-17.html (http://www.electriflite.co.uk/store17/index.php/popular-items/mn3110-17.html) on my Tarot 650 with foxtech 124.0 carbons http://www.foxtechfpv.com/foxtech-supreme-cf-propeller12x4-p-1190.html. (http://www.foxtechfpv.com/foxtech-supreme-cf-propeller12x4-p-1190.html.)
AUW 2480gm full house FPV setup with a Tarot 2D gimbal; 30A Multistar Optos that I flashed with SimonK.
My hover flight duration is 15min and actual flight time is 12min on 4 cell 5A. For argument sake if I added 2 more of these motors and ESC I'd have a hex with an aprox AUW of 2688gm.
I`m running 650kv with 12x3.8`s with bolted on props, no clamps
1400W multi eSoarer? Bet that thing's a beast!
Thanks guys for your help just trying to break into my piggy bank to see how big the pot is for 6 this time too :+

6S - see right hand column on the spreadsheet I posted below.
There is no doubt that running large props is the key to efficiency, which then leads you towards low Kv motors and a high cell count (6S). Ten years ago, when I used to fly to 200w/Kg rules with electric gliders, we achieved a VERY significant performance advantage by running 24 to 28 inch folding props on highly geared motors. Multirotors do have different requirements of course and you have to be careful not to go to too low a prop speed, which can induce control problems, so a compromise is required - (as always!)
Cheers eSoarer an interesting thought towards a good set up and duly noted :)
