I'm interested in some feedback to a couple of questions.

Are many/any of you running a dual redundant battery setup for your Whiplash Gas heli?

If so, what are you using? If not, what are your thoughts on setups and gear?

I was thinking of simply using dual switches and two 2100mah packs plugged with one into the receiver and the other into the gyro. I know a fair amount of plank flyers do this on their larger models.

Scorpion also make a little product called the backup guard which kicks in when your pack dies, has a brownout or the switch fails. Only issue I see there is, how do you know how long the main flight pack has been redundant for when your flying? Basically it's a 500mah 2 cell lipo that puts out a regulated 5 volts.

As always, I don't want to add too much extra weight than is reasonable.

Cheers

I like simple ; so a 3600 LiFe 2s pack through a Perfect Regulators soft switch direct to the electronics is brilliant on my Whippy G and N, my Whippy E's have a 2100 LiFe pack instead .(much shorter flight times with electrics!!)..

Most of my helis are running LiFe packs these days ..

Not sure if this applies to the whippy, but, on my Xcell gasser I installed a Lil jewel generator system. During one flight when I landed and shut down everything suddenly stopped working, no servo control. Upon inspection I found the battery had disconnected during flight, but everything worked fine as long as the gas motor was driving the generator.
In other words, battery failure/disconnect/dead did not affect the flight, I never knew anything was wrong until I landed and shut off the motor.
.
So the generator provides two functions:
!) Never have to charge the battery pack. For convenience
2) Redundant electrical system backup. For safety

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

Generator is the way to go.

Running LiFe with Perfect Regulator fail safe switch and the Scorpion back up guard on my gassers. The backup guard will tell you when it is under 30% charged via a blinking light.

A good back up system should be able to protect from dead batteries, failed switches and unexpectedly, I have had one of the batteries main leads break away from inside the pack.

Thanks flyers for your input.

Hmmm, Generator would be nice. I had been thinking that sometime down the track I will go with a Jewel Generator. Just not initially. The luxury of not having to charge a flight pack is very appealing However mdm and GyroFreak, how do you deal with the issue of not being able to keep a 2S LiPo or LiFePo balanced? Or is it a case of using a pack with a built in balance circuit? Maybe something like the Fromeco packs??...?

The scorpion back up guard seems like a good idea if I'm not running a Generator. So it's best to have the backup guard somewhere it can be seen during flight in case a battery fails close on taking off? The Whiplash can fly for about 15 mins (approx.) on a tank so having it fail early would mean I would be close on fully discharged if running off the backup. So either way, I guess it really does need to be visible so you don't miss the warning flashes... Actually I just read that it's not suitable for high voltage setups. Does that include LiFe?

Any other solutions/products/advice?

Cheers

LiFe is not HV, straight LiPo at 8.4 volts is. LiFe starts at around 7 volts and quickly drops to 6.8. Scorpion kicks in at 5 volts. One of my Whiplash helis has 6 volt servos, the other heli has HV servos.

Being able to see the indicator light is important.

My Helicommand overheated in the front of the Whip. On my second Whip, I mounted it on the tail boom tray and really like it in the back better. It then made it easy to stick the Scorpion to the frame, easily wire it in and have good visibility.

Good question, but since I was only using NiCads I have no answer for you. I am forwarding this question to my good friend who makes them and see what he says.

Thanks Paul,

Guess we'll wait and see what/any advice your friend has.

I had heard that heat from the Zenoah's should be monitored in the canopy. That's a good reminder for us all to do what we can to keep it cool(er).
LiFe is not HV
Thanks FastFlyer20 and noted, however my question was more querying the LiPo scenario. Yes, LiFe is not considered HV although does operate at a more sustained higher voltage than a 5 cell NiMH. Was just tacking that on the end of the comments to ask if it was at all any different in how the Scorpian would respond in a failure.

So to encapsulate; it kicks in at 5v then delivers 500maH of regulated 5volts to the system.

Cheers

How are you only getting 15min flight on you whiplash? Is it a gasser???? I have a 1005 and I am bored of flying before I empty the tank. Im getting about 45 minutes if I never land it.

Is anyone running a Jewel on a Hansons motor with Electronic ignition? Any issues?

Whats everyone's though on the electronic ignition? I hear its a bit better than the CDI but I don't like that it needs a separate source for power. One more failure point.

The RC format is magneto, an electronic ignition is not currently offered. HWC has a press release that they will have RC engines with an electronic ignition available soon.

Crank up a Whip to 2100 HS and watch the 15 oz tank drain in 12-15 minutes. More power = more fuel needed.

Been running the Jewel Generator for years with Hanson engines. Works long long time never a problem!

One mile of road will take you one mile. One mile of runway will take you anywhere in the world.

None of the ones pictured are an RC format.

scorpion BUG on HV is Fine
I run the BUG on 2 WG that are both running HV all around and the BUG has performed flawlessly and saved my Heli at least 3 times when I had total main pack failures and didnt even know it until I went to shut the electronics off and they were already dead.

This just saved my Whip G recently when a wire to the switch broke under the shrink wrap. I am more sold than ever.

Geat to hear!
Nice one Tom! It's always pleasant to hear of devices that earn their keep on our expensive machines.

I also purchased two Bugs recently, one is on my original Whip and the second to go on the second Whip currently in the making.
