hi beaner...my logo10-3d is, as you say, a smooth flying machine...unfortunately, on my last flight i had the dreaded 'berg lockout'...i experienced the glitch before at low altitudes or hover, and broke blades and bent flybar...but this one was a biggee...dived in during circuits....i just need to install the new frame, landing gear bows, main gear, etc...a friend and i are sending our berg6s to castle for their $30 upgrade to the new berg7...oh, the repair parts came to around $100 (including a ubec)...for another $100 i could've gotten a whole kit with all the parts i needed, and then some ...anyway, keep up your great posts...
