NU vreau sa intru in polemica si nici nu vreau sa ma dau important dar ground check este recomandat in toate manualele modelelor pe care le-am facut. Iata ce scrie in manualul lui Petrica
http://manuals.hobbi...0493-manual.pdf
la pagina 39:
"Ground check the operational range of your radio before the
first flight of the day. With the transmitter antenna collapsed
and the receiver and transmitter on, you should be able to
walk at least 100 feet away from the model and still have
control. Have an assistant stand by your model and, while
you work the controls, tell you what the control surfaces are
doing. Repeat this test with the engine running at various
speeds with an assistant holding the model, using hand
signals to show you what is happening. If the control
surfaces do not respond correctly, do not fly! Find and
correct the problem first. Look for loose servo connections or
broken wires, corroded wires on old servo connectors, poor
solder joints in your battery pack or a defective cell, or a
damaged receiver crystal from a previous crash."
Si nu se refera la o statie anume ci in general.
In manualui statiei Futaba 7CAP...atata am....spune:
"Range Testing Your R/C System
Please note that different systems demonstrate different range checks and the same system will range check differently in different
conditions. Also, the receiver antenna's installation affects the range test -- exiting the top of the model is ideal.
This is a brief explanation of range test. For more in-depth specifics on receiver antenna mounting, additional checks if
unsatisfactory range is demonstrated, range checking with gasoline powered engines, etc, please see our F.A.Q. page at
www.futaba-rc.com.
• Leave the transmitter's antenna retracted and be sure both batteries are fully charged.
• Position the aircraft away from wires, other transmitters, etc.
Test one - engine/motor off, minimum of 100 ft. range
• Have a friend view the model but not hold it, engine off. (People conduct signals, too!)
• Walk away from the model, working all controls constantly. Stop when the servos jitter significantly (a jitter here and
there is normal), control movement stops (PCM), or you lose control altogether.
• Measure the distance. If greater than 100 feet, great! Proceed to Test 2. Less than 100 feet of range check means you
need more information to determine if your system is safe to fly. Please see our web site or call support for additional
tests to perform before flying your system.
• Repeat with friend holding the model. Note any differences.
Test two - engine/motor on
• Repeat the test with the model's engine running and with someone holding the model. If a decrease of more than 10%
is noted, research and resolve the cause of interference prior to flying your model.
What your fully operational system demonstrates is the normal range for your system in those conditions. Before every flying
session, it is critical that you perform a range check. It is also required by the AMA Safety Code. If you notice a significant
decrease in range with fully charged batteries, do not attempt to fly."
