Alimentazione ricevente con la 2 celle lipo

Questa è una spiegazione tratta direttamente dalle FAQ di Scott Gray circa l'uso dei 5,2/5,6V

Why is the Reactor NOT adjustable when other regualtors are?
The Reactor was designed to be very user friendly and provide the best balance between increased performance of the servos and electonics while not damaging or overdriving them; decreasing your radio system's lifespan. Steady 5.2V is available to the RX and gyro/tail servo/accessories and a higher 5.6V power bus is preset to get solid performance and more speed from your CCPM or mechanical mix servos. You do not need to calibrate, adjust or worry that the voltage may not be set right. No voltmeters and resistive loads are required to set as with some other systems. Just PLUG-and-FLY!

....e questa è una FAQ specifica sui servocomandi Futaba, sempre dal sito di Scott Gray

Domanda
I have a question about the voltage of your Reactor, is there a problem using it with Futaba 4.8V digital servos like S9252 and S9255? I think the voltage of 5.6V is very high for a 4.8V servo. I know a fully charged 4.8V batterie has about 5.6-5.7V, so this may be the same, but this voltage is normally only for a short time not for all the time like I would have with the Reactor.
Yes, most servos are rated at 4.8V because this is the voltage of standard 4 cell battery packs such as are included with all radio systems. In reality, as you noted, a charged standard pack will give 5.6 or more volts. This is safe for the servos. You may notice that other regulators run at even higher voltages such as 6.0V. Some people use 5 cell packs and at full charge the voltage can be very high. This is too high in my opinion and my experience.

Risposta
I chose the 5.6V as a safe, but best performance voltage. The Reactor supplies this voltage perfectly constant up to the max amperage that servos can draw, so there is not voltage and current spikes and change in feel and performance during the flight. It is very noticeable the consistent feel the 5.6V gives the servos. 5.2V is also running to the RX and remaining servos such as gyro and throttle etc. This is a safer voltage for the high speed tail servos commonly used with today's gyros.

Alla fine , grazie al link di nigel1 ho deciso, e passo al duralite 5,1V 7,5A e lo collego diretto alla ricevente.
Costa poco e sul sito ne parla bene.

E questo è il regolatore Robbe dove viene specificato l'utilizzo ANCHE con servocomandi dichiarati a 4.8V

http://data.robbe-online.net/robbe_p...122_1-8476.pdf
......
The robbe 6 Volt Limiter generates a stabilised
voltage of 5.7 Volts from a 5-cell NC / NIMH or
2-cell LiPo battery.
The maximum continuous current is 5 A with
an NC / NIMH battery, or 3 A with a LiPo pack.
The peak load is considerably higher.
The advantage of the constant voltage supply
is that the power and speed of the servos
remains constant at all times, regardless of
battery voltage.
The Limiter also allows the use of servos
which are designed and approved only for use
with four NC/NiMH cells.........

E' una questione semplicissima. il cavetto col diodo non puo' alimentare tutto, non farebbe passare sufficente corrente, la Futaba si raccomanda di non usare le 6 volt ricavate dalle nimh o nicd in quanto danno oltre 7 volt a piena carica, ma una tensione stabilizzata a 5,8 non da nessun problema, il problema sono gli sbalzi, è comunque meglio per il 9254 e fratelli andare a 5,1 volt, ma anche a 5,8 stabilizzati sopratutto utiizzato per il gyro, e sconsigliabile ma non fa assolutamente nulla!!
Inoltre c'è molta caduta di tensione dal'uscita di 5,8 volt, tra spinette ricevente gyroscopio, fino ad arrivare al servo di coda, io uso le 5 celle normali, e per ora non ho fritto nulla, comunque quel regolatore è simpatico, ne ho ordinato uno pure io da provare.
