Hi everybody! After one year registered, today I write my first post here at RCU.[]

I've received a RDS-8000 unit. The throttle stick doesn't have the same distance between extremes than the other channels (about 2/3 only). Is this normal? Can this setting be changed?

zertsman

do you mean the physical distance the stick moves or the servo arm?


i can't say i've noticed on mine.. i'll have to check.

turboayuso

Yep, the physical distance the left stick moves in vertical way.

How are you doing this?

I'll have to see if I can find it again. Somewhere back in this thread it was posted how to do this. I'll look for it and see if can find it.

Select aux1 or 2 as your rudder dual rate switch. Example: Select etc. Page down until you see (MAS 1). Select RU. Page down. You see SLV 1. Select RU. Page down. You see 0%. Select +50 with the rudder to the right and +50% with the rudder to the left. Now turn your receiver on and move the rudder to full and while holding it there move the aux 1 switch up and then down.Watch what happens to the rudder. You'll get the idea then and can set things up the way you want.

Be careful to check every thing when you do this. My son accidentally coupled down elevator to up throttle while setting up elevator to rudder. The result was total loss of the plane.

I fixed my post 903 issue this way.

Denis,
Thanks for covering me. I haven't had a chance to go back through and look for the post.

Turbo,

Just checked and all of my Transmitters are that way, Futaba, Airtronics, and Hitec. Less throttle stick travel than elevator, aileron, and rudder sticks.........RJ

Thanks guys. Great idea.[8D]

turboayuso

Thank you very much, RJ.

Apart from this Airtronics I only own a Multiplex one, which has complete travel for both sticks, so I wasn't sure if this was right (suspected it, as the radio didn't show the TH-Hi warning when turning on with throttle stick at lower position).

True for Futaba and Airtronics, but my Hitec Optic 6 has equal stick travel for elevator and throttle.

djlyon

Yup normal for all Airtronics, Futaba and Cirrus transmitters I have seen. Hitec up and down stick travel is the same for both right and left stick on my Eclipse. But you want to know what? I never even noticed until you brought it up.

Me neither, I had to go and check all my radios.

Thanks, your post on rudder D/R is quit interesting. I'm going to try it.

Does anyone know of a way get exponential on the rudder? Just out of curiosity does anyone know way they have been leaving it out on all their radios? It sure would a nice thing to have.

The reason we were told a while back, (not in this thread) was that there was no room on the circuit board.
You can get Expo and Dual Rate on the rudder by using the Heli program with your plane. I have done this on my .40 sized profile Ultimate. I just copied it from the airplane program. Worked great. You do lose the dual elevator function and flaperons though. I like them two features for my giant scale models so I stick with the airplane programming. I've also become really smooth on the rudder with no expo.

Does anyone out there trickle charge their RDS8000 after charging? I charge over night and use the Lil Trickler. I recently noticed that the voltage is dropping to below 9.6 on tricke if it has not been charged in a week. I could leave my JR;s and old Airtronic on trickle for months after a full charge and they were ready to go. Any ideas? I just noticed this

Also, it looks like the 2009 Tower catalog has wiped all Airtronics stuff from the pages.....? Not that it matters I guess, but most hobby shops do not carry Airtronics.

Most hobby stores don't carry Airtronics because most hobby stores in the United States get their merchandise "floor planned" from Horizon Hobby and/or Hobbico. This means that they can order all of the Spektrum, JR, Futaba, and Hobbico radio equipment they want (within their credit limit anyway) and they have sixty to ninety days to sell it before they have to pay for it. If they want to stock Airtronics equipment, they either have to do most of their floor planning business with Global Hobby, like the Hobby People stores in the Southwest United States do, or they have to pay cash up front for Airtronics radio equipment.

A store's ability to floor plan is based on their volume of business. If you're already carrying a large volume of Horizon and Hobbico product lines, you won't be able to move enough of the Global or Ace product lines to get decent terms with your smaller distributors. If you could stock all of the DX6i and DX7 radio systems you could sell in three months at no cost, or pay for your RDS8000 stock up front, which would you stock and sell?

As long as JR/Spectrum is kicking Futaba's tail, Tower will probably resell Airtronics stuff. I would guess that the RDS8000 is Tower Hobbies' best selling 2.4Ghz air radio under $500, even though they'd much rather be selling 6EX and 7C FASST systems. They still get a little profit from every RDS8000 they sell while at the same time increasing the market share for "other" in the JR/Spektrum versus Other 2.4Ghz radio battle.

From Hobbico's standpoint, every product that is sold to an RC pilot that doesn't come from Horizon Hobby is at least a minor victory. That's why Hobbico resells engines from Thunder Tiger and Magnum, they're not Evolution or Saito. That's why they resell some Model Tech ARFs and Airtronics radio gear. That's why Hobbico provides products to Global like Futaba radio systems, O.S. Max Engines, and Real Flight simulators. In the world of RC distribution, the enemy of my enemy is my friend.

Does anyone have a link for a cable to hook the RDS8000 to my computer for use with a sim? I got the FMS package with all kinds of cables, none of them fit the RDS 8000.

I apologize if this has been answered before, I missed it...does anybody elses trans. battery not hold a charge for longer than a couple weeks when not plugged in? From day one, mine will go almost completely dead within one or two weeks just sitting in the case.
It charges up just fine and works great at the field but drains quickly when not in use. And no I'm not leaving it on accidently.[8D]

djlyon

Yup go back and look at my posts on pages 39,40 and 42. I also have one transmitter that has held it's full charge for 4 weeks now.

Hy Flyr,

I just got an email back from Global on this. My TX battery will hold the charge for about a day or two and die off. It will work fine for two hours of flying right after an overnight charge. And it dies off on trickle charge too. Anyway, they told me to send the battery back. I have a feeling there are some "funny" batteries out there if you look at earlier posts. But they can;t do more than offer to check out and replace if necessary.

Thanks for the info. guys. I did go back and read thru the threads. It appears I've got a bad battery. I guess that is one reason the transmitter price was so good, they went with bad batteries!! It appears some are having better luck with higher capacity NiMH batteries. Anyway I still love the transmitter.[8D]

BelAirBob

I have had endless bad batteries from JR, both transmitter and flight packs. I solved those problems by getting batteries from SR batteries. They are expensive, but if you buy say an 1100 mah battery, it will always charge back to that capacity. You get what you pay for with batteries too.

I was having the same problem with my batteries so I changed to eneloop batteries and at 200 ma and almost no self discharge they are great and i'm always ready to fly.http://www.stefanv.com/electronics/sanyo_eneloop.html check it out.
