NAZA: Known Limitations & Issues

[iDrone]

The Vision's NAZA autopilot relies on SENSORS interfaced by connectors. It has been suggested that flying several minutes with excess vibration in combination with large stick input and wind gusts may push the autilot's handling envelope and/or cause its sensor connectors to move & become intermittent causing a number of problems, like flips. Obviously motors & props should be balanced to minimize vibration, and the use of flexible props is recommended over rigid. Although NAZA for Vision is not specifically discussed, here's more about these limitations of NAZA & NAZA-M at the bottom of this page: http://www.multiwiicopter.com/products/naza-m-v2-with-v2-gps

I'm curious what you guys who've used NAZA in other aircraft think. :?:

For educational purposes for our P2V owners, I copy their warnings here:

Excludes / Requires your attention

GPS function - Please dont assume GPS is magic beans - make it your business to understand GPS fully and monitor the number of GPS Sats in view at any one time and never operate where you are completely reliant on GPS - thats just not professional or based on fact - you must be able to fly in FULL manual mode and return to land yourself for legal reasons - in an emergency - disable all advance modes and fly in manual mode (gyros only).

 KNOWN ISSUES by Team MultiWiiCopter.com - > for consideration prior to purchase of any NAZA * -  this autopilot has limits - Pilots must respect and understand their aircrafts limits

NAZA is a great hobby autopilot for Quads but it runs on SENSORS - if your thinking toy fool proof - you will crash it/flip NAZA one day - it has LIMITS ->crashes or what you think are "random flipping of NAZA" or control outages are caused by "over confidence" and familiarity leading to assumptions and pushing the robotic modes out of their envelope - ignoring inflight led warnings - combined with large stick inputs in Robot modes (ATTI or GPS) often accentuated by windy or gusty days and VIBRATION   ->   1) the user not checking dynamic vibration levels - its 99.9% chance a random "FLIP" several minutes after takeOFF is your own fault or ; 2) Corrosion and oxidisation of pins (poor maintenance of push-connectors by user) over time  - Realistically you must use corrosion protection sprays on ALL PINS and ALL CONNECTORSFor NAZA_M YOU MUST BALANCE ALL ENGINES & PROPS FULLY - NAZA does not tolerate vibration - We recommend soft flexible props such as 9050 triples or dji 1038 ONLY - rigid carbon props are the natural enemy "FLIP" recipe for a naza when flown in ATTI modes with large constant stick inputs - again this happens after a while 2-4 mins after T/O or on FPV when pilots "ignore" LED "Sparking warnings" or simply cannot see them (on goggles)  to centre their sticks.  Operation of NAZA on Goggles is NOT RECOMMENDED unless you have an assitant pilot to report LED warnings to you.Place NAZA as close as possible to the C of G and use full gel mounting tech to isolate all vibrations.  Use soft flexible props for FPV - not hard rigid props.
