my dads new 1600mm b17 from hobbyking ,first flight ,we flew it tottally stock with a 2200 mah 3s battery, after the flight feels like it needs some lead in the nose but we are just going to a 3000 mah battery ,one of the retracts pulled out on landing, not glued in properly and glued to the paint rather than the foam ,only thing we did was put some packing tape on the bottom of the wing to stop any flex already spoken of in rcg,thanks for watching and keep watching for more soon.....to be continued.............................
