It is puzzling that new systems are shipped with 4cell Rx packs when reports suggest that 5cell packs are less likely to suffer a voltage drop that may lead to a Brownout. I realize that as long as the capacity of the Rx pack is sufficiently high enough to meet the demands of the system, a 4cell pack should be sufficient. I just do not want to have crash while I am waiting for the manufacturer to tell me that my flight packs are inadequate. I would rather play it safe, especially since the difference in price between a 4cell and 5cell pack is not that great.

I see your point, however.

When the Spektrum radios first came out they were having an issue known as a brown out but many people found that if you used a 5cell pack it would
cure the problem, however Spektrum now has fixed the issue by making their receivers with a faster reboot or so they claim.

I dont own a JR/ Spektrum system but I have no reason to doubt they have made their receivers with a faster recover from a brown out condition, However
I think the rumor that you need a 5cell pack for all 2.4 systems is just that a rumor.

Increased Rx battery voltage will increase servo torque and speed. This in addition to helping decrease the likelihood of a low voltage brown-out, is a win-win-win situation. I've decide to use only 5 cell batteries in my planes, now.

I may have jumped ahead, but has anyone suggested the OP verify a good installation of the Rx. Those short antenna wires can get hidden from Tx view pretty easily. Don't ask how I know.

Just because an RC Radio system ships with a 4cell Rx Battery pack does not mean that the 5cell pack is not recommended. I think it is safer these days to go with a 5cell Rx pack unless you have servos that can't take 5v. Even then, I would use a 5cell pack with a 5v regulator.

I use 2cell LiPo Rx packs, with a 5v or 6v regulator, or A123 Rx packs without a regulator. My JR 791 Retract servos are the only ones I have that are not 6v compatible. I could put 5v regulators on the Retract Servos and leave the rest of the system at 6v, or just use Air Retracts and a totally 6v system.


There is nothing wrong with 4cell packs and 2.4 I have the Futaba FASST system and it works fine with a 4cell pack and for multiple flights. But my point was
that unless Horizon includes 5cell packs with all its systems then they cant say you need a 5cell pack for the system to work right.

futabas are different. were discussing how to prevent speks from delinking. And tower says for optimum performance blah blah blah.

i have a lucky 13, 60 size plane. super tigre .61 engine. 600 mah pack with a volt watch. it flies three ten minute flights before it even shows any drop or one lite out. it's a 4.8 volt pack too. i have a ar500 rx spectrum in it but have heard others complain about spektrum rx's. i have four and i don't think they are as reliable as the 72 mhz radios. there have been alot of problems with spektrum radios,since they came out. now there is a problem with the trainer jack catching fire from shorting out,in the spectrum forum on discussions. every week you read something different it seems........................................RON

I too have or are in the process of switching to all 5 cell receiver packs (6 volts). During the plane's construction, you have to analyze the current draw from the battery... how many servos are connected? What are their rated torque capacities? What is the wiring distance and gauge? Heavy wiring requires less current. A smaller sized battery will produce less demand amperage for a shorter period of time. Amps and Voltage go hand in hand.... In my opinion, I would rather use a larger battery than loose a plane. By starting with 6 volts, you have a larger overhead to draw from... and are less likely to drop below the receiver minimum threshold. I also prefer the sub-C battery packs as they develop more current than the double-A size. Of course, the smaller planes may not be able to carry the larger battery packs and limit you to AA. An extra AA battery is a small price to pay for keeping the plane up. For someone to tell you that 600mahr 4.8 volts is plenty, is wrong without checking the size of equipment installed. If you are flying a lot of aerobatics, you are burning battery power a lot faster than straight and level flight. Some servos are drawing 500mahr each... testing with a 0.5 load is misleading. Your immediate demand might be 4 or 6 times that... The bus of the spectrum receiver can handle 20 amps... In large scale planes, you need to look at adding a second battery pack and the 9 channel spectrum receivers allow for that.

On the spectrum receivers when you experience a loss as you described, it could have been a brown out loss of power and the receiver will be blinking.... this is your indicator of a big problem. You can simulate this... turn on the transmitter, turn on the receiver, turn off the receiver and then back on... the receiver will be blinking. Reset the blinking by turning both off and on again. When you recover your plane after an incident, you should look at this before turning off the switch.

Your situation is likely different than any other... voltage testing with load is important...

It doesnt matter what size pack he was using honestly. I am not sure why that is where everyone is pointing.

1. If you have a 5 cell pack and pull the battery (NO VOLTAGE), let it sit for a day, come back and plug it in, Rx should still be bound no problem. When you hit the on / off switch on the receiver, your cutting voltage to the Rx, same thing. The Tx holds the "address" to that plane / receiver. That is why Model match works, make sense? The tx see's a specific address to your Rx and hands out a certian freqency, just as your WiFi enable laptop see's a router and the rounter authenticates it, and hands out a IP address.

2. Send the whole thing back to Horizion.

3. Next time you bind do this.... Bind it the first time on of the receiver, NOT the switch.
-Plug the bind plug into the battery / bind port on the Rx.
-The plug the battery into any open channel.
-Follow the directions for your specific JR / Spektrum Tx to bind. I know the 6i has a diffrent bind pattern than a Dx7, 9303 and so on.
-Once bound for the first time, set your rates, reverses, yadda yadda as you would normally do.
-Now set the plane as you were going to fly, plug the bind plug into the switch, and then bind again. Why may you ask? If you bind once, it see's the Rx, but the Rx Boots to the default settings your rx was, that is usually full deflection and then some on some of your surfaces, untill the Tx see's the Rx, then they go neutral (amperage spike). When you bind twice your setting the failsafe as well. So now you have a failsafe, and a Rx that boots to a neutral deflection. I set my second bind with the throttle completly shut and full down elevator. This way, if I loose connection, rx goes into a fail safe I set. I would call in a uncontroled controlled crash. Engine off and into the ground it goes. I would rather loose the airplane than kill someone with my 30% or even a .40 size model by letting it fly away and having to go chase it to a field full of kids and its going in at 1/2 throttle.

Seeing that you are using a 6200, I have to mention that I have one that completly failed on me on the ground. I thought it became unbound as well, but thought that was not possible. I tried to bind it again with no luck. Thought I had a bad battery, and tested. my 4 cell 1100mah nicad read 5.4v. Good. Put a new pack in and it did the same. I noticed the elevator start fluttering. coincidentally, I moved the Rx and noticed that it was VERY hot. Back to Horizion it went.

Also a word of advice. DO NOT BIND AT THE FIELD IF OTHERS ARE FLYING WITH JR / SPECKTRUM EQUIPMENT. You wont bind, or can knock someone out. Do that stuff at home, and not at the field.

You seem to be focused on the bind problem... After going in the water, I would say all bets are off on loosing the bind. The water could have shorted something.

I am focusing on the loss of control originally. Flying along and all of the sudden he has no control of the plane. It flies off on the default settings. I would say that this is not a frame loss, it is total loss of signal... the Rx shut down and most likely that is a battery problem. The transmitter could be the problem. I would hope that he range checked the setup before flying. So, you are flying along and you have a "brown out" condition... the receiver shuts down and restarts... it does not reconnect to the transmitter. It does start blinking. You loose control and the batteries and receiver are on when you get to the accident scene... You check voltage and battery is not dead... it just does not have enough juice for the load... moving the surfaces does not load the battery... while flying the air provides the force resisting the servos and runs up the electrical requirement. The only thing you are left with is a blinking light to tell you that the receiver shut down.

Yes I agree with you to bind it before setting the plane up and bind again after completing the setup... Whether the bind plug is in the receiver or charge jack makes no difference. A bind is a bind... either works or fails. The fail safe settings are created with the second bind.

As far as binding at the field... I do not agree with you. There is nothing in the literature about that... binding is a low power operation and a receiver has to be in the bind mode for anything to happen. The chances of two planes being accidentally bound is minimal. Yes I bind at home because most of my radio work is done in a quiet space without all kinds of suggestions by my flying buddies.

Hi FLAPHappy,
I stand by my comment that the very high capacity NIMH "AA" cells are inferior to those of 2000mAh or less for on board receiver use.
I don't use 4.8V packs for anything and haven't for a long time.
Your 4500mAh receiver packs certainly are not "AA" cells, so they are good for your large planes, but not anywhere near the capability of a 2S 2300mAh A123 pack of much less weight.
Capacity is one thing "C" rating is another and Nimh in "AA" size cells have poor performance in that area, that's why so many are switching to A123 cells.
Pete

Honestly the ony reason I focused on the bind problem is because the OP stated that it was unbound when found. The blink I know is a visual that you lost you signal for a short amount of time, and in the interest of the consumer JR backed this up by the quick connect feature that was released. The receiver will brown out at 3.5v

I honestly dont beleive it was a battery problem nor a bind problem. He stated he load tested the pack before and after the flight and it was nominal. So if a pack is nominal, the only other logial issue is the receiver itself, failed switch, yadda yadda. I also had a FULL and out right failure on the grounf with my 6200 and it got hot to the touch.

I personally beleive it is a receiver issue, but then again, who knows.

Dont beleive me about the binding while at the field? Key up multiple JR / Spektrum 2.4 radios and Rx's while at the field and try to bind a plane. Doesnt work...

Coming from the systems administration field I can tell you that the more points of connection between A and B always creates more failure points. This is why I said to bind from the receiver first. You dont have a switch between the receiver and pack. Its direct, no option for failure except from doing it wrong.

I will try the binding here at home with 2 active transmitters on and a third binding.... will let you know.

Several of my receivers are rather difficult to get to once installed. I have no other option than to bind at the switch. Adding a 6 inch piece of wire and connector is not significant. You can take things too far... at some point you must have trust... If it binds, it binds.

If you plug a Y harness into the Batt/Bind port in the Rx, you can leave the Battery plugged in to one side of the Y and connect the Bind Plug to the other. I do this all the time because I have a voltage regulator plugged in between the switch harness and the Rx because I use LiPo batteries. I cannot Bind from the Switch Harness Charging Jack because of the voltage regulator.

This is true. I am possibly moving to lipo's on my 35% once it is complete, and will need regualtors if I go with them.

Thanks.. I am curious at your outcome as I have bound at the field before while guys were on the ground with their 2.4 JR's keyed up and it has failed every time. Thanks for the test, I only have one x9303

I had the same thing happen to me yesterday. It's was T-34 with a 46 motor spek 6000 reciver 7.2 lipo battery with a turnigy 7.50 amp BEC on the 6v jumper. I had one brown out and was able to save it but the second brown out and (maybe the third) the plane hit the ground a complete loss. I Check the battery and at 3amp draw, battery votage was 5.1 with the jumper in the 5 volt setting with 3amp draw the voltage was 4.8. I will be sending this back and hope this does not happen agian.

Ok This is the hard part. Even my futaba browns out when it gets low. The spektrum rxs are very voltage sensitive. What this means is the battery gets past peak and the c rating changes a little bit. So a hard load will pull all the voltage and brownout the rx. recovery from this isnt always fun. IEG That last hard turn before you land.
