Compass looks secure with hot-glue and aligned perpendicular with front of aircraft.
While I've always been a Futaba guy ... I ordered my FrSky Taranis X9D & X8R receiver combo from Wayne at Aloft Hobbies. It was the newer B-version with the 2000mah battery and the X8R has the PCB antennas. The 2.4ghz communication protocol is ACCST (Advanced Continuous Channel Shifting Technology) and supports a Telemetry channel and RSSI. Great service and got it in a few days via FedEx. For about $35, I can get more matching receivers (for the next model aircraft). From what I've been reading in forums, I don't think I would personally trust stock Nova radio.
If you can't afford a Taranis radio-set, other experienced pilots said the Turnigy 9x combo is also good. Ignoring the whistles and bells of the Taranis, difference is mainly the 2.4ghz encoding technology, Telemetry capabilities, and Fail-Safe abilities. This Turnigy radio is really just a re-branded clone of a popular radio that many companies cloned (ie FlySky FS-TH9x) .
But for me ... a 2.4ghz 9 Channel radio and receiver for around $225 was too good to pass-up. Actually, when using with APM-FC and a $15 CPPM adapter, you get 16 channels. The Taranis seemed like the right choice for me.
I really have no prior helicopter or quadcopter flight experience. Heli-X is a nice simulator and it has a DJI Phantom quad ready to fly. I could use the Taranis, but instead I just use an old FM/PCM Futaba-6ch. I also ordered a $50 (brushed-motor) WLT v262 to practice with in real world and wind.
