A few changes in build plans but still on track. Build parts starting to arrive slowly but surely. A few delivery mishaps that have delayed the build and resulted in going with an Xbee pro S1 rather than the 3DR telemtry. To be honest I flip flopped, decided on Xbee, then 3DR and due to a cancelled order being shipped ended up with the Xbee.
While waiting for parts I have been reading the wiki and forums daily. I can not stress how important this is as a process before and during the build. Reading troubleshooting post and watching videos on calibration of RC controller and setting up of mission planner.
Decided to make my own power distribution harness and forgo the distribution board I bought to save weight and space on the frame and keep it low profile. Fairly tidy soldering job with heat shrink and testing the connection with a volt meter. Trying to keep weight down by shortening cable lengths to keep things tidy. Lots of soldering this weekend on ESCs as well as resistor and cap for the sonar sensor.
Purchased two black closed cell (water and fireproof) foam blocks (1 prototype - 1 final) to make a custom canopy. Planning on mounting APM, telemetry, sonar, optical flow, airspeed sensor and receiver to the foam. Going to extend the central mount with the space carbon fibre tubing I have to allow the mounting of two large lipos. This should help vibration and endure spacing between sensors that are affected by magnetic and electrical noise from motors and ESCs. Settled on FrSky TX/Rx with Turnigy 9XR and 2x 5200mah 3s lipos.
Next step is mounting all the above to the frame in anticipation of the final parts Arduino Pilot Mega Flight Computer + GPS + Power module. But before I get ahead of myself I need to refine my setup/ calibration plan as well as flight checklist.
Big thanks to Multirotor.co for the T-Motors parts. Look forward to ordering some MN4014-11 330KV motors for my next build - X8 ;)
