I'm at first model, I have to learn a lot before to fly it.
My first query is:
Futaba Rx has came with 4,8V battery and my servos work at 6V. What should I do in this case.
Second query is:
What voltage regulator is? Do I need it? witch one? What is that doing?

Most servos work at 4.8 and 6v with a few exceptions. Particularly some digital servos that work only at 4.8. They produce less torque and are slightly slower at the lower voltage. The only reason you would need a regulator is if you were running a 2s Lipo or if you were running a 6v battery with a digital servo that can only handle 4.8v. So post your specs on servos and gyro and see if we can point you a little more exact in a direction.

tho...what size model are you talking aot.there is another type of voltage regulator,often mistakenly called a bec,that is used with a 2s lipo pack replacing the 4 cell battery pack.because a 2s lipo is a lot lighter and more powerful.however it should be run thru a voltage regulator to drop its voltage down to 5 or 6 volts

I have Multiplex Europa BB servos and Graupner Gyro system Piezo 2000 and I use Futaba 10C radio.

I own a 60" helicopter size. I can buy 2S lipo, but what voltage?

May I use Futaba rx R6014FS with 6V?

2S Lipo is going to be 7.4V nominally, but 8.4V fully charged. You should get a switching regulator and knock it down to 6V to avoid frying the servos.

I use 2S A123 for my .50 heli, and I get 5-6 tanks with it. I run a CC BEC to bring the voltage to 5.7V.

Futaba advanced technology allows this receiver to be the first 2.4GHz receiver able to utilize all 14 channels. It retains G3 2048 resolution and Futaba Real Time Response. Simple one-touch binding - no plugs to mess with or lose A full range system for all aircraft from giant scale to Park Flyer applications-no need to buy separate receiver for specific aircraft Dual Antenna Diversity allows 2.4GHz FASST Futaba transmitter to select the best reception between the two receiver antennas with no signal loss. Rubber grommets installed where antennas exit to eliminate stress and fraying of the two antenna wires. This receiver will only work with the 2.4GHz 10C or higher channel 2.4GHz transmitters.

What battery is usually used to power up the electric panel witch start the fuel pump, the starter, etc. Should I use a ordinary car battery?

That's what were here for.

Those batteries are usually 12V. Probably not what you want to power the RX in this case.

What if I'll try to connect 2 li-pos in paralel mode, it will have more life? What about charging them? should I charge each one or together. I hope are not stupid questions.

Watch this video I made about BEC's and regulators. Might help.

Thank you for the video, I've got it, the only think I missed and is hard to understand (because english is not my language) is what about gyro and the gain, I have two separated connectors for that. I thought I must to connect them on two different channels. You have explained something else about that. Can you make me understand exactly how to connect both of them? (try an easyer english):cheers

Finless
09-29-2009, 07:32 PM
What gyro? But most gyros have 2 connectors. One goes in the rudder channel (channel 4) and one goes in the gain channel which for futaba is channel 5. The gyro menu in the futaba radio controls channel 5.
Your gyro manual should tell you which connector on the gyro is rudder and which is gain. Most gyros the connectors are color coded.

Thank you! I will read the futaba manual, I know witch connector is gyro and witch is pitch, I was confused, I thought I have to put them together replacing some wires.

This might help you for the 10C radio. I did a full set of videos on this radio explaining how to use it.

I already downloaded all :)). Very helpful. When I'm finished with this model, I will return with other questions, like how do I calibrate the blades, what are the correct parameters.
