Hey all, Bought my first Quad about 4 months ago,a Guai 330x s and then the 650 xair. After crashing both numerous time i found most of their weak spots...lol With the 330x I didn't like the frame so I upgraded it to the SIGMA XM-Q4-600GF V2 I am just now finished building that, Which I might add was no peice of cake. No instructions,no hardware list, Had to go by the pictures and for 230.00 i wasn't to happy about that. Oh well gotter done. The 650 the landing gear was the first to go as you all probable know already, So I took some designs i had seen and made my own version which added about 200 grms. Cut them out of a road sign that was givin to me.Much more stable now. I am waiting for dilivery of my next project any day now since it cleared customs in S.F ca. yesterday. Its the Full carbon fiber Y6 copter frame from foxtech can't wait. Anyway as you can see I am HOOKED. Nice to be here thank you.
