Some of you may have seen Stephen "Sleepy" Cinch's review of our plate designs back in June of 2015. We've since updated our line to include 4 main models: the F1, F2, F3 and F6. All model kits come with high-grade 2.5mm thick center plates (3k toray carbon fiber); rectangular aircraft aluminum...
The triple props are Tarot 15.52 nylon props w/ KDE 3520 400KV motors... The smaller copter has no-name T style CF 14.55s on top and 13.65s on bottom; they're mated to DYS 4114 400KV motors.
The F5 X8 frame kit includes 2.5 mm CF center plates, (4) 500 mm aluminum booms, (8) 3 mm CF mounts, retractable landing gear w/ controller and all hardware for $490.
I have the same gains as Sleepy... Another trick you might employ is to use Zeal tape on the FC. It works wonders with the SX in windy conditions. I was amazed at how much more stable the copter flew in the wind w/ the Zeal tape installed.
