Hey all. I have a JR 8303 probably 8 or 9 years old. I have it on the ham band and it is PCM. Also, I always bought the highest end JR receivers when I built a new bird. All of my servos are 4131, which at the time was about the best there was, as to speed, torque, and accuracy. I been out of the hobby about 7 years, and I am getting back in now. I would send my 8303 back to the factory about every 2 years for a new memory back up battery, and new operation battery, and also for a frequency check and tune up if needed. The radio is just like new operational wise. Should I look to upgrade to one of the newer radios, with digital servos, and all that stuff. What would I gain, other than more model memories. Any more accuracy, servo speed, better control layout? Ross

Yes, Yes and Yes..

Now that does not mean you need to do it...

Digital servo's will center better, faster servo's will make the model more responsive, and a newer radio will communicate faster & will give you a better feel for the model.

Heck - Ive never seen or heard of an 8303, 8103 or a 4131 servo...

But then again, I have never flown anything but 2.4Ghz & digitals

this thread will stir up some fire no doubt and you will get alot of opinions, lol very strong opinions so brace yourself. There is far better stuff out there as far as radio and servo's are concerned, take your time and do some research before buying is my best advice.

If you were into JR back then, JR is still going strong. The 2 radios most people use (EDIT: if they use JR/Spektrum) are the Spektrum DX7 and the JR X9303. Both are great. The 9303 has easier programming and more features. The gimbals are smoother too. Lockouts are far and few in between with 2.4 GHz technology (some field are 2.4 only). By the way, Spektrum and JR Rx's and Tx's use the the same spread spectrum technology and are interchangable. Most of todays new and exciting micro bind and fly helis are Spektrum technology. I've never owned Futaba stuff, so I have no idea how they perform. My 9303 is pretty cool and I can't find a reason to upgrade it. It does more than I'm capable of doing.

Do some research on your own to make your choice.

hrm...were helicopters able to fly 7 years ago? they sure as hell were.

the equipment you have will fly just fine. i'd send in the radio equipment for a checkup just to be safe. turnaround from horizon is about 10 days door to door IME.

now, when you're outflying the equipment there is of course better stuff available--for likely less $$$ than you spent 7 years ago. depending upon your ability 7 years ago, you might not be outflying it for a couple more years...in which case there will be better stuff available than you can buy now.

so, i'd say don't go out and rebuy just yet.

if it ain't broke, break it.

You can only fly with the newest and best technology. As new stuff comes out, the old stuff is instantly useless, worthless, and you can't even bury it in the ground, as it won't stay there, it's so bad.

Why that old stuff is so terrible, that NO ONE was flying wild and crazy 3D with it, man they were barely able to hover without flipping over and catching fire.

I would suspect that other than perhaps needing new batteries, the equipment you have is sufficient to fly any of today's helis. It seems that you took good care of your equipment.

You can fly what you have just fine. Get back into flying, if you feel the need to upgrade or replace equipment in the future, then do so. But really there is no compelling reason to dump what you have and buy all new.

And was that an XP8103 radio or an XP9303 radio you have?
better control layout?
Someone above indicated an emphatic yes.

Strange, I've got transmitters that date back to the early 1970's and the primary flight controls -- aileron, elevator, rudder, throttle are still in the same place now, as they were back then. Even many of the switches on my old Futaba FP6-FGK are still in the same place as their counterparts today.

+1 ! I'll bet the stuff you have will fly just fine.

EXCEPT the batteries. Throw them into the nearest barbeque pit or other open flame (JUST KIDDING!) - maybe better to take them to a recycler, perhaps a Radio-Shack or some such. Just replace the battery packs and all the fuel lines, especially inside the tanks. and rubber dampers (I'm assuming you have an old heli that equipment is inside now.)

Those 4131's are as reliable today as they were in the height of their "time". Get fresh batteries, "run what you brung" for now, all the while doing research to decide where you may want to go next when you do upgrade. This spring will bring Fun Flys to attend and get first hand opinions on what to buy.

I have an 8103 as well, and only semi-retired it when I got my 10X. If it was the 8103 to 9303 (9X, whatever . . . ) I probably would have not made the change myself . . . Since you are on a Ham band, the issue of park flyers and shootdowns pretty much does not exist as it does in 72, so a move to 2.4G is pretty much a personal preference, and in no way necessary or even advisable . . . I am still on 50MHz ham, as I have been for close to 10 years, and have yet to experience a glitch or conflict . . . the ham frequencies are still that clean, and you don't have to fight for spectrum with all the barely legal (if at all) Chinese crap that shares the 2.4G ISM bands with the latest fad in R/C gear . . .

Granted, the new radios claim greater resolution and perhaps speed, but I did a quick analysis on at least the resolution, and determined that unless the total slop in your linkages is less than a couple 1/1000's of an inch, any gain in resolution is lost right there . . as far as the response time improvement, it's true, but again, I doubt seriously whether the average human can detect it, since the differences are far less than a typical human's reaction time . . .

Digital servos will run on anything, so that is a complete non-issue as far as your transmitter and receivers are concerned . . .

Bottom line is that it's pretty hard to go wrong no matter which way you go! As others have said, though, new batteries would probably be a very good idea.

Ha ha. You will find, along with anything else, some people have to have the newest and next greatest thing. Oh look, my Trex is a year old, better get the newest one. Crap, my radio is a couple years old, even though it still works I had better trade in.

I'd say fly with what you have and upgrade as needed or wanted. I got a friend who just got TWO 9303's for $200 because the owner went 2.4. He flys mostly planks and sailplanes but he is not interest in 2.4. He has no real reason too. Since most of the people are going 2.4 his airways are clearing up. Yes 2.4 is good. If you buy new go with it. But do you HAVE to switch, no.

I flew JR 8103 radios for a long time. In fact, my father just retired his 8103 last year when he went 2.4ghz with a 9303.

It's a complex, costly, glow powered anti-gravity machine!

there is absolutely nothing wrong with an 8103. flew one for 12 years.

i recently sold mine with a spektrum module to a local flying buddy after winning a dx7 at a funfly.

the dx7 has the 8103 software so it was an easy transition for me. i'd still be flying it if i didn't end up with a free dx7. loved the 8103.

8103 was my first radio. It can be converted to 2.4 no problem.

We still don't know if this fellow has an 8103 or a 9303, but in either case, the radio is still not only useful, but can be updated to 2.4 GHz simply by adding the Spektrum module system.

if the pcm 10 i bought back in 1991 is still working for me today, the 8103 is not outdated.

My son and I both have XP8103's, and I also have XP9303. And we both fly ham. And he can 3D the crap out of his heli with that 'old antiquated, non-2.4 GHz junk'. Yes the newer stuff might be a little faster, but ask yourself this. Am I pilot enough to notice? Well, last time I looked at my drivers license the last name wasn't Youngblood. The stuff I have is still way more radio than I need or can take advantage of.
