Voltage regulator 5.1v or 6v

[Fixxxer]

Hi all,

Getting a new heli which will be ccpm, now I'm no jason krause so won't be putting any great load on things for a while but have decided to change over from the nimh's i'm currently using. So firstly do I go with a 5.1v or 6v
regulator. Now it makes sense to me to spend the extra cash and get an arizona dual output regulator then at least I can change over should the need arise & also will the 2400mah peerless be sufficient or is it a case of get the bigger 4800 pack, I realise this will affect the number of flights but is there any of probs with the larger capacity batts ?

Any thoughts are welcome.

i would definitely recomend the arizona regulator even under high loads these things maintain their voltage very precisely. besides the look great too :-)

2400 your looking at about 6-8 flights if your using digitals all round. on a raptor i would probably go for the 2400 as the CG is almost always too far forward with a decent sized battery.

I have just fitted the 2800mA 7.4V duralites with a 5.1V regulator to my Predator. I have hitec digitals on the pred and was using a 6V 2000mA nicad pack. I also have the Weston UK battery monitor fitted which gives the battery level, but also shows the load on it during the flight. I am not a heavy F3C/3D pilot and my aerobatics are mainly loops, rolls and stall turns. However, after each flight, the monitor would show a green light for the battery voltage, but there would also be an orange light on indicating the load during flight. The problem with Nicads, apart from memory effect, is that they can appear fine on the tester/monitor, but when they reach a specific voltage, their capacity drops off sharply.

The 7.4V pack with the 5.1V regulator effectively gives you a redundant cell which provides a reserve. My monitor stays in the green and even after 6 flights the battery is at 8.4V.
The battery and regulator cost me £81.00 from Skyline and considering they're fitted into a £1000.00 model, I think it was money well spent.

The great advantage with the arizona system is that you can adjust the servo voltage while keeping the tail steady at 5volts (great for CCPM systems)..

Simon did a great little review of all the systems here :- http://www.littlerotors.com/articles...0606/index.asp

Thanks for the info folks, have read the littlerotor's reviews and decided to go for the arizona but am waiting on an email back from real raptors reguarding stock issues.

I run an Arizona Reg on my Titan with digital servos. I have the 2400mah Peerless and it works a treat. Balance is good. I even have an on-board glow starter which runs from this and a Sparton Voltguard, no problems !

Yea i'm flying duralite as well 5.1v and 5.3v

4000ma in the heli and 2800ma in the plane

quite like the duralite system apart from charging is nice and slow with there charger!

which battery monitor do you have ? I could do with a couple really!

The original post was 18 months ago now so I went with the arizona reg but thanks for the info anyways

I don't bother with a monitor as they don't apply any load, best way is to use a tester like the little square futaba one after each flight, then you'll know how many flights you can get comfortably before needing to charge.
