Looking at the Gryphon Extreme Heli DC-DC Voltage Regulator
GVR-7020B for my 5550e. Any thoughts or better way such as LiFe battery?

Its all earth!

I'd run a regular lipo, maybe 3000+ mah 7.4v and regulate it down to 6v.

Or run a higher volt lipo, and regulate it down to 7.4v if you have all high voltage servos.

I would go li-fe 6.6v unregulated as batteries are safer to charge and no regulator to go wrong !!
That's my opinion it really comes down to what you feel safer with and confidant with.

LiFe's are great, I have been running them for a few years, the wiring is simpler and one less point of potential failure. In the end, either way will work.

Another vote for the LiFe 6.6V batteries here. I've been running them for about a year and a half on mine and it works great.

And a LiFe setup costs less too...
I am so happy to be done with regulators, one less thing to buy and wire.

Yeah and one less thing to fail and gets rid of a possible current choke point if you do heavy 3D. I've been using 2 cell life for years on any and every servo I had in my box old or new and none have failed. I been using the cheap ones from... for like $9-11 for 2100-2500 mah too, man get the life you will never look back and keep the money on that reg.

Another vote for LiFe packs.

I leave mine on the heli and plugged in 100% of the time.
I even charge it on the heli since LiFe packs don't burn.

I literally never use the word literally right.

I just got a Gryphon 7020 or whatever it is called. Seems to work well. The new Reactor X looks interesting as well.

The Life packs scare me a little, probably I don't know enough about them. I understand you charge them and then fly to figure out how much you can pull out of them and when to recharge etc. The part I'm not sure about is what happens when the pack begins to reach the end of it's life. Do you suddenly find yourself in the air with no power or can you see it coming when charging or what.

I'm sure someone can fill me in.

They have an almost flat discharge curve, making for very consistent voltage to all the electronics.

For "how many flights on a charge" - put in a few flights, recharge and measure how many mah you put back into the pack and divide by how many flights were flown. Now divide mah per flight into the pack capacity. I usually stop 2-3 flights short of the pack capacity.

LiFe can be charge more times than a LiPo, don't mind staying charged for extended periods of time and since LiFe is a more stable technology, they don't have a habit of catching on fire.

Are you asking if it puts out 6.6 volts up until the last cycle of its life and just dies in flight?

That's not how it works.lol...
Signs of wear will show in the charging.

By the way...A LiFe pack will last about 3 or 4 times longer than a lipo...Maybe a lot more than that....Years and years.

You guys have me sold on life. I have been using 5 cell nimh for my fb 50s but now i want something better for the fbl, and the idea of adding one more electronic unit that can fail is stressing me out.

Only problem with running a Li-Fe direct is you either run no switch which is a pain taking the canopy on and off to plug/unplug or you need a very heavy duty switch.

60% of the time, it works every time!

You don't need a heavy duty switch.

RX packs aren't the same as flight packs.

5-10 amps is the most you'll need.

I mean heck...all the power needed is delivered through servo wires.
My switch is a JR and that's all it is...servo wire and a light duty switch.

regulator. Can adjust for servos and different types. Still cant trust Life packs. Seems like they go dead quicker than lipos. Yeah more points to fail, but what wont fail on a heli? More wiring, but can trust the lipo discharge delivery a lot better.

Are there any big name sponsored pros running Life packs?
Seems every one I've ever noticed runs some type of regulated system.
