dubya_o,
I'm not sure what you mean by a servo "binding up" during flight. If you have binding on a servo to the point that it is causing the servo to draw that much extra power then there are bigger problems than not having enough juice in your battery. All of your control surfaces should move freely without any binding on them.

binding servos? scared of that![X(]

Things go wrong/break sometimes. Especially with beginners(no offense meant to you new guys). I just like to do everything I can to be safe or save the plane. I just use these packs on the 17 year old PT20 I use to train new folks with.

dubya_o,
I understand what you are saying about things breaking on a plane, afterall they are a mechanical device and things to break sometimes. But are you trying to say that you these batteries shouldn't be purchased because in the off chance that something breaks the battery could go dead?

No, I never said don't buy these batteries. They are fine for a .25 to .40 trainer/sport plane using 4 or 5 servos. On larger/faster planes or 3D planes with large control surfaces and and digital servos on top of that I think that normal flight loads may be enough to cause these batteries to temporarily have voltage drops large enough to cause the receiver drop out. Just something to be aware of.

Dubya_o, where are you getting your data from? I do not see any information on these batteries that states "under extreme loads from digital servos could cause voltage drops large enough to cause the receiver to drop out." My question, wouldn't every battery have problems if under extreme conditions would have large voltage drops? When I setup my planes, I make sure I do not have any binding and they are free flowing. I do not think I will have any problems with these batteries. I have only heard of good things about these batteries.

But, thanks for your concerns.

This is from the FAQ on theFutaba web page:

1)Receiver------"An ABSOLUTE minimum operating voltage is very near 4.0V. Rx's typically use a 3.3V regulator which requires an additional 0.7V to power itself, resulting in the 4.0V minimum. In application, however, it is typical for performance to become severely degraded as power falls under 4.3V DC."

2)servo---------"The reason for this warning is that the servo can produce high-current draw from your batteries. If you are using NiMh or Li-Poly batteries, make sure they are capable of delivering sufficient Amps to the servo."


I think you said you have an Accucycle Elite? Do a discharge on the pack starting a 300ma. Let it run for a few seconds and note the voltage. Now try it with a 1amp discharge rate.

I never said "Don't use these batteries". I just said I won't use them in certain situations. Get the info and decide for yourself. What servos are you using and what in what plane will you be flying them?
