Can I ?
Can I use a BEC instead voltage regulator to power the electronics on a gasser ?

Yes, but use some style of back up power such as a generator or Ultraguard. You could use a LiFe or LiPo battery and eliminate the BEC or regulator but once again, some type of back up power is cheap insurance.Tom

If HV is an issue just use a LiFe pack and call it good. Personally, I wouldn't bother with a backup solution like the UltraGuard on a heli running an rx pack.

Backup solutions are a must for electric helis. With the exception of forgetting to charge your rx pack, when was the last time you heard of one failing?

Gassers are unique. Switches and packs can fail, wires can break. If potentially saving a $2500 heli is not worth a $50 investment then by all means pocket the $50 Tom

so by adding in another failure point this is good ?

Keep it simple no switches, use plugs.
isolate your electronics from vibes
I would use a bec/VR only if I had to.
I'd rather use 2 x 6V nimh/nicad or life packs in paralel instead of adding failure points

yes, unless you live in North Korea

The ultra guard is not a failure point as it comes in when the primary means of powering the electronics fails. It is a "back up".Team MikadoUSA 480XXTreme, 550SX, 600SX, 700XXTreme, 800XXTreme!!

any thing more than what is necessary becomes a liability, If it is electronic it can/will fail.

you are better using 2 batteries in parallel if you are concerned about battery failure

That does not back up power to the receiver, only the battery. Plus if wired in parallel without any safeguard such as a diode and one cell dies, it can deplete the other pack.

If it works for you use it, but it is not a true back-up.

what kind of silly logic is that

you have 2 6v packs
1 pack loses a cell and drops to 4.8
the other still has 6V supplying
the damaged pack at 4.8 no longer provides and as for depleting the other pack it will take longer than your normal flight time for it to happen.
At the end of your flight you should be checking your batteries.

again that's if your concern is voltage protection I'd invest the 50$ into a good battery first

even if you use a back-up everything in your set-up most likely a servo will end up failing or a link pops off or something stupid that despite all your efforts causes it to crash.

It's a part of life spend it wisely

Technically . . . a BEC and a voltage regulator are the same thing.

If your battery puts out a higher voltage than your servos/electronics can handle then you certainly need something. Do you have to run a battery with that high a voltage ?

Keep it simple and use good build practices.

Just strap a second battery on there. LiXX chemistry is light and compact enough.

I am working a Radikal G20 for friend and I nodes it had no power going to the electronics, the voltage regulator is shot, I have a BEC lying around and I was going to use it, it needs something to lower the voltage, because it has a 2 cell lipo and the servo are only good for 6v, so I should be good to go.P.S. sorry for the spelling or the grammar I am dyslexic!

you should check the current capacity of that BEC . . . make sure it can handle the servo load . . . sounds like the old regulator couldn't.

The 6V rating means it can run on a 5 cell NiCd pack that is up to 7.0V off the charger. Your battery pack is 8.4V right off the charger.

Make sure the RX and gyro can handle that also.

If so . . .

You need to loose at least 1.4V . . . two 5A schottky diodes in series can do the job . . . clean . . . simple.

is the spark plug < magneto or electronic ?

if electronic doesn't that require a separate power source ?

yes you can the cdi requires 4.7v bu I had issue's with the cdi and servos
running of the bec didn't have enough power to keep up with the servos so I used a life pack on the cdi and a regulator on the servo's
Insha Allah made in america
