Some other items and procedures that I would recommend:
Try all the functions as soon as you can (probably during the second flight after you are
familiar with the normal flight controls) to be sure they work. As i think most will agree, this
little bird has more than it's fair share of issues. The quicker you identify any minor
problems, the quicker it can (hopefully) be fixed before causing any major problems. Like
crashing.
As soon as the low voltage alarm comes on, bring it back and land, no point in running the
battery into the ground as this can shorten it’s lifespan.
Do a post flight check on all major components to make sure nothing has come loose or
damaged as soon as possible.
Check should include:
Chassis screws and motor screws.
These literally hold the quad together and hold the
motors in place, they can work loose from the in flight vibrations. Tighten as necessary.
Motors
. If they are excessively hot after immediately after landing this may be an early
symptom of a defective motor. If this happens refer to troubleshooting section for help in
diagnosis.
Propellers
. Check for nicks and cracks in the blades, especially after hard landings or even
seemingly gentle tip-overs. Any damaged props should be immediately replaced. Check the
prop nuts as well, these should actually get tighter with use but are worth checking too.
Battery
. Check for excessive heat and swelling of the main battery, this will indicate a
battery with potentially dangerous issues and should be replaced as soon as possible. Check
battery voltage and balance if you can, excessively low voltage or imbalanced cells can be
another indication of a battery about to fail. If you have the FPV version do the same for the
camera/transmitter battery built into the gimbal. Wait before recharging the LiPo battery, it
will be quite warm (but not hot) after flight and it needs to cool before charging it up again,
this will further extend the life of the battery.
Chassis
. Inspect the actual chassis of the quad for any signs of damage. Remember that this
is the body of the quadcopter and that it has no reinforcing internal structure or ‘skeleton’
and any cracks, chips or excessive flex can be a weak point that could potentially fail in mid-
flight.
Your second flight will be perhaps even more telling, if you are used to the controls, push it
a bit further and faster, try straining the motors a bit, do a full throttle 'punch' straight up
and note any odd noises, rattles or erratic behaviour as this may indicate a screw loose or
badly imbalanced prop. If all seems fine then start to play with it more, let it stretch its legs
so to speak, do full speed passes or take it higher, whatever you feel comfortable with to
your skill level.
