  • try this QR brain 4 in one ESC on 3DR quad. it fits very well between the two plates. it makes a great difference which i do not know how. the quad does not moves laterally even in manual mode3692901136?profile=original

  • I'm like cd bulk box head =)

    I like the propellers.  They look similar to the Graupner props that Dave C put on his copter that won last year's AVC.  DaveC's was also at it's heart a 3dr quad but seriously pumped up with high kv Tiger motors, those props, 4S battery and a couple of other bits.

  • The telemetry antenna is one thing i really want to do differently, on a similair design i couldnt make the escs significantly hot, so im assuming this wil be ok. The battery goes above the escs and under the electronics.

    Clean build but I see at least three potential weaknesses:

    -where do you put the battery?

    -your telemetry antenna is horizontal and burried in cables and electronics which is is optimal to say the least

    -your ESC s are burried internally and on top of each other so the heat cannot dissipate

  • Looks very clean and should work fine.

    APM height offset doesn't really make much difference accel or gyro wise, but from a wind / gust or relative wind standpoint it would be better to have the enclosure lower and a compass-GPS on a mast.

  • As long as it works =). You could have simply purchased the external Mag with GPS and had it higher up.

  • it was lower, but due to magnetic interference i had to put it higher. now the motormot returns 4%. i flew it shortly and it looked ok. any experience with apm that high?

  • The APM looks overly high above the CG, it looks problematic. Otherwise, look good.

    Very clean design.
