RE: JR 9503
That actually helps keep confidence in the 9503, this once, was simply another human mistake. Which even I have been guilty of. Ha-Ha.

RE: JR 9503
Got mine back today. Odd thing is that I only had one model (little J3) programmed in at location 10 and it was still there when I got it back. According to all I've read here it should have came back with no data in it. That means they didn't do anything to mine. Right?
I guess I'll call them for the THIRD time tomorrow and see if my transmitter has really been fixed! This is frustrating!

RE: JR 9503
Received mine back on the 6th day. All my programming was intact. Only thing I lost was my bind. Mine was in and out on the same day.
I only had one model programmed. A tech sheet was enclosed saying it was flashed.

RE: JR 9503
hey SO, I got mine back with all my models still in the program but some of the settings were messed up. Like servos reversed. It is working great.
I am now trying to figure out how to put the aileron to flap mix in so the flaps operate with thew ailerons to give me super ailerons for a really fast roll rate.

RE: JR 9503
I found this info on page g-26 of the x9503 manual. I was surprised to see a large number of people using lipo batteries in there JR transmitters. I have been using a Hyperion 9.9v 2100mah LiFe battery in my x9303 for about six months without any problems. You can use the standard wall charger or the optionial JR 270mah wall charger. The battery has a 10.2v cutoff built-in. My x9503 has been working fine for almost 4 weeks using 5, 6, 7, and 9 channel receivers. I gave my x9303 to my son.
All current JR and Spektrum transmitters are designed to operate using a 9.6-volt transmitter pack. A fully charged 3-cell Li-Po pack puts out 12.6 volts. This higher voltage can overload the power-regulating transistor causing damage and or failure, possibly in flight. Many of our customers have experienced failures using 3-cell Li-Po packs and their use in JR and Spektrum transmitters is highly advised against. The X9503 2.4 system will operate for over 15 hours using a 2700mAh Ni-MH battery.

RE: JR 9503
That’s an interesting pack!
Can’t tell from the photo; is there any issue getting that big connector and adapter tucked inside?
Used a LiPo all last year in my 9303; have a diode wired in series which drops about 0.7 volts.
My flying bud just used the LiPo direct in his 9303. He looked at the spec of the linear voltage regulator by JR and knew it was close to being maxed out on heat – too bad JR doesn’t spend a bit more for a better reg, think a $500 TX would be worth it?
We both have swapped the packs to the new TXs.

OK - thanks for the info guys. I'll just fire it up and use it then. (I did note they put a new version sticker in the battery compartment.)

RE: JR 9503
I have run 3s lipo's in my DX7's for over a year with no problems. Horizon told me the deal about the lipos on the phone. I am not a tron guy and have trouble understanding a fully charged nimh turns on at 11.7 V and my lipos are at 12.6 V. That is less than 1 V difference. And they say it is enough to blow a transistor???

RE: JR 9503
it's not necessarily the peak voltage that does it - it would be more the sustained higher voltage that the LiPo battery provides -
Extra voltage input to a linear regulator is just extra heat that it has to get rid of to do it's job. Heat will shorten the MTBF (mean time between failure) of any active electronic device, eventually some of them will fail, a lot higher percentage of them if they're hotter.
It's not JR's fault if you want to use a battery pack with a higher voltage than what they designed for. Sure, there's other ways to do it (the regulator) , but a manufacturer doesn't have to allow for ALL of the options.

RE: JR 9503
I solder the connector to the battery, it is to tight with the red connectors in the battery compartment.
If you leave the transmitter on by mistake, it does not destroy the battery.(LiFe)
You don't have to take the battery out to charge it.
LiPos void the warranty.

RE: JR 9503
Some people that use LiPos as their Tx battery are using Diodes, from Radio Shack, in the battery leads, to drop the voltage .3v/Diode. I have used LiPos in my XP9303's, 9CAP, and 8AUPS, for the last couple of years. I do not leave the Tx on for long periods of time when the voltage is above 11.7v. I can go for a couple of weeks without charging. Charging takes less than an hour and less than half an hour with the newer LiPos that can charge at 2C and 3C.
A123 cells are also a good choice, with Eneloops coming in next.

RE: JR 9503
The JR2500 mah battery is an excellent batttery and mine is three years old. I never had a problem with it, but after three years of charging and discharging, I did not want to take a chance on it going bad while flying a $2000 plane. I still use JR2500 mah batteries in other JR radios. I have seen too many failures with lipo batteries to trust them in my transmitters. Also, the LiFe and A123 batteries can be recharged over 1000 times. I flew four different planes today with the new 9503 with zero problems, I think it is going to be a great transmitter. I would like to see a plane with retracts using the slow servo feature. I have seen it work with flaps.

RE: JR 9503
Had a very interesting conversation this weekend with someone who is well placed within the RC Industry he knows HH very well!
I wish I could say it made me feel better; though, it won't keep from buying HH stuff.

RE: JR 9503
I just got a 9503 and this data transfer program. the program installed correctly (i think) but hangs my computer when i try to data transfer. There are mixed input on the compatibility with the 9503.
Has anyone here actually installed it and transferred data with a 9503? Any other experiance that might help me?
