Hi, did you fly it? Normally we have to center the IMU to the frame? did you do a code change?

Sorry for late response. I have been making some multi-copters without consideration of centering IMU. Mostly offset location for ease of wiring and USB connection. The code has been no change from the default setting. Flight behavior look like no affect from the offset, about 1 inch. I need some other input for the offset location of IMU. Thank you,

Nice Y6!, let me ask a small question, from where did you get/buy these arms? are they made out of broken ice hockey sticks?

Hi Ruwan,

Yes they are very light weight carbon fiber hockey sticks I stripped and dremel cut them in half and drill holes to lighten them further.  This frame with landing gear weighs 95g.  I am amazed at the strength of the material.  I can drill a 3mm hole 2mm from the edge of the frame and the stuff doesn't shatter or break even after months of flying and crashing.

Thanks Steven.  After reading your earlier posts, I've been searching for broken ice hockey sticks for a while. No success yet :-(

I might as well show off my toy too, now i've had a few flights and am very happy with its performance and stability. A few things i will be changing; Support for the nose - to stop some flex/vibration, wider slots for the battery velcro straps, thinner foam around the ESC's, and changing most of the screws to countersunk heads to reduce the thickness a tad.

Frame: My own quad design, plan to put a F1 style body on it (design files available if anyone wants them)

Controller: APM1

Motors: 880kv jDrones

ESC: 30A Mystery

Props: 12 x 4.7

Battery: 5500mAh 3S Wild Scorpion (12-15min Flight time)

Radio: Eurgle 9X

Video: 520TVL sony Cam / 1.2GHz Tx

Extra's: Sonar, Xbee, Optical Flow, GPS, Mag, 180A Atto-pilot
