FIRST FLYING MANEUVERS Part 5



CRASHES
3) If the drone moves forward or backwards or sideways, trim the drone. See manual for your drone. If there's no trim function, push right stick forward or backward as necessary to keep it in approximately in the same position. 

If you panic, or if the drone seems to have a mind of it's own, pull the left stick all the way back and let the drone crash. 10 foot crash usually results in the drone bouncing slightly with no damage to drone.

I dropped many small drones from over 25 feet many, many times with no problems other than a slight embarrassment that my reactions are so slow.  I did trash a motor, but hey, I think it was faulty? No excuses. 

The grass is there as your safety net. Use it. 25 to 50 hovers should give you more confidence to go on to more complicate maneuvers. You will have had some more panic crashes. The drone should still be in good shape.

Crashes are always an embarrassment. One thing to remember is if its going to crash and you can't stop it from crashing, PULL OFF THE THROTTLE. If it crashed throttle on, it can damage the drones ESCs or Electronic Speed Control(s).

Wikipedia:

     An electronic speed control or ESC is an electronic circuit with
     the purpose to vary an electric motor's speed, its direction and
     possibly also to act as a dynamic brake. ESCs are often used
     on electrically powered radiocontrolled models, with the variety
     most often usedfor brushless motors essentially providing an 
     electronically generated three-phase electric power low voltage
     source of energy for the motor.

     An ESC can be a stand-alone unit which plugs into the receiver's
     throttle control channel or incorporated into the receiver itself, 
     as is the case in most toy-grade R/C vehicles. Some R/C 
     manufacturers that install proprietary hobby-grade electronics
     in their entry-level vehicles, vessels or aircraft use onboard 
     electronics that combine the two on a single circuit board.

CONCLUSION
Try to fly everyday. If not possible - whenever you can. Keep a log book. Where you fly, what aircraft (drone), how long, windy? etc, and of course the total time spent flying for the session, and a description of what you did or learned.


Charge the batteries as soon as you can after flying. NEVER overcharge the batteries. Do not depened on the charger that came with the drone. If you don't have a voltmeter, go on Amazon.com and buy a cheap one or go to Wal-Mart, Harbor-freight or Home Depot. 

Best $10-15 you'll ever spend. Monitor the batteries after 30 minutes of charge. Write down start and stop time and voltages.
After a while you know how long to charge but not overcharge a battery. If your serious, get a microprocessor controlled charger. About $25 from Amazon.com. 


It will charge any NIMH or LIPO battery correctly and not damage batteries by overcharging as the included chargers for the inexpensive drones tend to do.



Keep On Flying!
