Fly my new H9 33% Cap today and had a little glitching on some surfaces.

The receiver batt is a 6v 1800 mah Ni-Cad
The ign batt is a 6V 1400 mah Ni-Cad

Neither of these have regulators on them. After I charged all night both of these batts were well above 7V and almost to 8V
Would this be a reason for glitching?

Both of theses batts will be replaced this week with Powerflites and regulators.

I am just trying to find out if I may have another problem other than high voltage that would be causing the glitching.

Ignition electronics are seperated from the receiver electronics by at least 14 inches.
No metal to metal etc etc.,

Wayne :
Brian and I (P51 at the internet fly-in) both run unregulated 6 volts. We BOTH (a year apart) started out with regulators, BOTH of us had glitching, BOTH of us took the regulators out and all is fine, I DID ALSO change to a PCM RX too, but Brian did not and all is fine. The weekend we found out about Brian's glitching was up at the Rantoul fly in, after he told me he was using a reg, I told him about my problems, he took it out and has been flying unreg since then. He is using Airtronics and I JR with Hitec servos.
Also you will get 7+ volts on a good hard charge, even more if you use a peak charger, I have had mine in the 8 volt range after a peak charge.
Other then the problem how did the beast fly. It would probably fly better with a better pilot on the sticks. LOL

The plane is awesome!
It did evreything I threw at it easily.

Very solid in 3D.


Hopefully, my battery change this week will help with my glitching problem.

Are you guys talking about getting glitched in flight or nervous servos on the ground? What type of regulators were these? Switching regulators have been known to cause radio interference probles. If you need a regulator use a linear regulator.

I use 5-cell systems without regulator...there are a few futaba servos that futaba has said are okay for 5-cell use, but are clearly noisy with 5-cells...Hitec servos seem to do well on 5-cells...

When using a regulator, keep in mind that you may not get the highest torque that you desire, and which is listed as the spec on the servo, due to the current limiting of the regulator. you'll have 6v, but no current to deliver....

Try to do it without a regulator if possible.

The current is a function of the supply voltage, the back emf of the motor and the resistance of the motor. At stall there is no back emf so the current is equal to V/R. If the regulator maintains 6 volts you will have the maximum current and torque available at 6 volts. If the regulator goes into current limiting the voltage will drop. If it drops too far you could go into battery failsafe or the receiver could quit working. Either of these might cause the pilot to feel he was getting glitched but I would think it would be more like "I ain't got it" for a few seconds.
Make sure your regulator can provide the current you need and parallel them if you need to.

I never thought about a regulator limiting the current at the regulated voltage. I read in an article about the 2001 TOC that only two pilots had 5 cell regulated systems and one flew on 4 cells systems. The rest used unregulated systems.

Ohd:
We both were using in line regs.
Glitching in the air!
Next big plane I will be using 2-4.8 packs instread of a 1-6 volt pack.
Wayne:
What size of packs are you going to and how will you charge them, WHY are you going to them, WEIGHT??
RORO

Why would you use two 4.8v packs? I presume you are using them in parallel, and can only think that you are using them to get more total current capacity.

A second reason is to get redundancy in case of battery failure....If yes, run them each through their own switch.

I need to explain myself.
I am using a PCM RX to supply 5 servos hooked up to a 4.8, 1900mAH battery. Also a JR Matchbox to supply 4 servos in the wings of a biplane with its own 4.8, 1900mAH battrery pack. Seperate switchs for both.

I have glitch problems with a Futaba DIgital radio.
I have removed low batt. fail safe yet I still get a glitch in the throttle.
I would like to know how to remove the E-Reg from the reciever?
Or would I be better served by changing battery brands to a battery that allows more current flow. And what battery would that be?
I'm using 4 duracells/ Pro Cell.

Help Needed.

I think there may be a different source of noise in your plane....

what kind of plane, what kind of motor?....where are the servo and receiver components placed in relation to the motor....what kind of pushrod...metal clevis and throttle arm?

Sean

Edge fanatic,

H9 Cap
ZDZ 80
JR 8103 PPM Ner-549 Rx

All ignition components away from receiver components.

I am almost sure I have found the problem to be the Aileron extensions and the Y's that go to them.
new ones on the way.

Thanks.

I have lay ed these servos and others (to make sure it is not the servo, or the receiver) on a table, put a load on them, and the glitch shows up when the voltage indicator reach's the red LED.
The batteries are new, and have been changed.
Servo's are new, and have been changed.
This tells me that the batteries are not supplying the current required.
Is there a battery that has a higher current rating than duracell pro cell, and if so who's?
I have herd that the long life batteries are internally resisted to limit current out put.

What is a Duracell pro cell and why are you trying to use them? Try a NiCd or NiMH pack.

My response was actually directed to the other gentleman....

But you did raise a cause I had not thought of....sometimes it is indeed the extensions that cause the problems....I use only extensions having gold-plated connectors...and limit the length to only what I need.

Good catch!
