Default 2.4 GHz voltage protector?

Just want to know haw many of those flying on Spectrum use the capacitor to prevent sudden drop in voltage?

If you are running one battery in your system, especially if it is a 4.8v pack, you should run the capacitor. If you have a redundant system, don't worry about it.

Why doesn't everyone use 6 volt packs with 2.4G ? Seems like a better solution.

We already have the answer from Danny. In plain English "it don't help". How many places are you going to ask the same question? Dennis

Dennis, so 20% of the jet guys flying with the capacitor so far don't know what they're doing?

BTW i do value Danny's response HOWEVER he sells the Spectrum modules & probably so do you THUS debating this issue is NOT in your personal interest. That doesn't mean it does NOT EXIST![X(]

2 batteries are not necessarily going to help you if you're pulling a lot of current. I've seen 30% 3D planes go down with Spektrum and they were powered with 2 lith-ion batteries. I *think* the solution is to ensure you're regulator can handle a high amp draw and you use deans connectors for the batteries. In all 3 cases, the guys were using standard connectors on the batteries.

Your poll shows four guys. 16 either don't or think it's hype. give it a break. It's not for planes period. Good batteries of the right size for the demand of the plane is all you need. This lock out issue has been beat to death all over the place. It won't happen if you take care of your stuff.
To question Danny in his answer that may not be truthful because he works for Horizon in a safety issue is beyond belief. Dennis

I talked to horizon tech support about these. They told me the one they sell is designed for car usage and is useless in aircraft

here's the link for those who didn't know what it was:

http://www.*********.net/index.php?m...ducts_id=10718

after my initial research here's what i compiled;


1) it works like this> prevents short drops in voltage to prevent the 4.2 V lock & reboot sequence of the Rx

2) also, it clearly states is is designed for land use

3) i have found threads describing the lock of Rx in airplanes

4) enough people use it in planes as an "insurance" same way they use 2 Rx; 2 power packs; etc.

5) ALL the people associated with the Spectrum product continue insisting it is NOT needed in planes

YOU BE THE JUDGE!

Cheers,
Vasek

PS I am in NO way associated with ANY of the products mentioned above. I am switching to Spectrum, thus this quest for info.

Joe, you're right, the use of 6v for the 2.4 is probably the easiest prevention fix;

- do you use a regulator with the 6v packs?

- if yes can you post a link to it pls?

- did you come across any servos that don't like the 6v juice?

thanx,V.

Vasek,

I use unregulated 5 cell nicad packs in all of my planes. I use mostly JR servos and a few Hitecs. There's never been a problem with any of the JR's. The only servo that hasn't held up well is the Hitec HS225. I'm sure that there are a few other servos out there that don't like higher voltage, but I haven't run into them. Best bet is to follow the manufacturers recommendations.

The only anomaly is that occasionally the servos will jitter when first turned on just after fully charging the battery. In that case all I have to do is wiggle the transmitter sticks a few times. That causes the battery voltage to drop a couple tenths of a volt, the jitter stops, then go fly.

Same with me. My batteries show a peak charge of 7.2 volts, then they sit at 6.5 to 6.2 thru most of the day. At 6 volts I re-charge. I believe in KISS. Dennis
