I'm am interested in purchasing a regulator for my raptor 50. As I've been doing some research, I found that there are quite a few to choose from. I'm not sure exactly what I should be looking for as far as lipo battery size, regulator size, 5.1v, 5.3v, 6v etc... Could anyone point me in the right direction toward a proven setup that is relatively inexpensive?

Thanks,

Brian

FROMECO stuff is very good! I have 2 regulators on R50 & R90

You can choose the voltage betwen 5 to 6V

The Fromeco regulators are one of the best ones out there. It allows for flexibility in selecting a regulated volt(5v-6v) for cyclic and throttle, and has a fixed volt of 5volts for rudder servo. But it does come at a price, and that is its bulky size and weight.

If your current servos are rated for 6v, you might want to look into Western Robotics BEC, which you can get at ReadyHeli. Not as flexible in selecting a particular voltage, but it's definitely lighter.

A UBEC and 3S LiPo is perfect for a 50; I run 5.4v in both of mine.
I get 10 flights from a 2100 battery. If you already have some 3S lying around it's very cost effective and reliable.

Matter of fact, I recently picked up a 6V ubec that I'll ship for $40 including a step down for the gyro.

I heard that there is an align regulator out. What about that one with like a 2s 1400 setup? Does anyone have any experience with those?

Can you run the Arizona regulator on some 3S 11v 2200mah lipos? Dont know if the regulator can reduce down to 5-6v?

The Align has the 2in1 that comes with a 1900mah lipo rx pack, a led voltage monitor of sorts, and it even lights your glow plug, all for a little over 50 bucks. You need a tail step down if you are running a 9253/54 or 9251/56 tail servo.

Regulators

You can also use a 7.4, 2 cell 2200 lipo and a SGP (Scott Gray Products) reactor. You get 5.6 volts to the cyclic an 4.8 for the throttle and gyro, or speed limiter.

The qualitity of the reactor is extremely good.

In answer to the original question, the more voltage the higher(better the servo specs). You will get a higher speed and it will be faster. OOps, that doesn't apply to all servos. Some servos are 4.8volts(ONLY). A fully charged 4.8 volt battery is 5.3volts. So a 5.3volt system will run all servos.

But, 6 volts gives the servo a kick in the pants. But, most tail servos are 4.8 volts only.

The solution for the duralite regulator is a .7 volt step down. The Gemini system from duralite has a built in step down. The Arizona regulator has a built in step down, and the voltage to the other servos is adjustable. Not familiar with the Scott Gray regulator, but my limited understanding is just that, limited(answers anyone).

The duralites are digital regulators, which translates to less wasted power. The Arizona regulator is analog, which translates to more wasted power. the Scott Gray is? (someone fill in the blanks).
Is the power loss between the analog and digital system noticeable (can someone help me here).

You will need a 7.4v lion or lipo battery to run the regulator.

Some interesting points. I would want the most efficient design for its size. Maybe we can narrow this down with other inputs from their experiences.
You will need a 7.4v lion or lipo battery to run the regulator.
So You cant use 3S 11v 2200mah lipo's? I figured the regulator would be able to take it down to the 4.8-6v needed. Am I wrong about this?

Ive used duralite but then I tried this novac the specs seem low but I used it anyway Ive had in all my helis for over a year and never had a failure and plenty of juice at 6v and small ,lightweight hit 3d hard loaded still happy and trusted

Last I knew, Duralite, Fromco, and the Reactor are all Linear regulators. This has been covered a bunch of times-

Any reg that recommends a 2S lipo is linear. These types "waste" the extra voltage to heat, but since it's only couple volts it's not as bad as it sounds.

Medusa and Koolflight systems make switching regulators, which work best with higher voltage inputs (3S or 4S). They are more efficient, but may not deliver all the current for bangin around a 90 size.

What about the align 2 in 1? I know its linear, but would it be an economical choice for a raptor 50? Does align make a 6 amp regulator that isn't the 2 in 1?

Brian,
Yes they do one called an RCE-B6X,it's just a 5.8v 6A linear type regulator with no step down
I quite like the battery voltage LEDS on it but didn't trust the tiny on/off switch after i crashed with one (though i now think it was the battery that had suddenly discharged too much).I've now by passed the switch with a blob of solder,just to be sure and re shrink wrapped it, then run it through a heavy duty switch between it and the battery.
So far so good,got quite a few flights on it so far with my Knight 3D

I believe that I have decided to go with the duralite 6volt reg. My next question is if I'll see any performance gains with the servos I'm currently using. I'm using old-school jr 4131's and ds8201's. I haven't been able to locate any specs sheets to show whether these servos can even handle 6 volts? Any help?

thanks!

Brian

Like playfair said, the Duralite, Arizona, and Reactor are all linear(analog) regulators. All of the extra power is dissipated(wasted) as heat, and is why the Arizona requires such a large heatsink for the added performance.

That said, I like the 5.4V UBEC(switching/digital regulator) in my 600n because it's small/lightweight and I can get 4 HARD 3D flights easy with only a lightweight TP 910 mAh 3S at less than 80% drain. Although the rated current is only 3A cont/5A peak, I've never had problems with it in flight and the voltage hardly budges under rapid and loaded control surface movements and the unit itself hardly gets warm. This is running 9451 digitals on cyclic, a GY611/9256 on the tail, and an ATG/9253 on throttle. IMHO, this setup is better than any linear regulator.

Another switching regulator(BEC) to consider is the new Castle Creations BEC. It's the smallest BEC I know of, rivals the Arizona's current at 10A, and its voltage is selectable from between 4.8-6.0V.

My 2 cents

Another vote for Fromeco

Swapping out all my duralite for fromeco

too many battery failures with duralite.

Just ordered my Fromeco Arizona for my 600N project!

I like to try and support our American Companies as much as possible and its nice to know that we can make a quality product still.

Just IMO.

Anyone try the Castle Creations BEC? It can handle 7 amps continuous and it is adjustable voltage. The price is decent also!
