New Radio - 2006/12/24 15:40 It was nice to meet everyone at the meeting last night. I look forward to becoming a member next month. For those that were not there my name is Jim Tarman. I live in Worcester Twp. and I am a "rookie". I have had several converstations with Rob Schaffer and Jim Secrease. Thanks to Rob I have a better understnading of my direction in the hobby and thanks to Jim I will be saving some money on my first plane.

I plan to invest the savings into a better radio. I have alre3ady invested in Real Flight and with some luck, and training from instructors, I will have some success in the upcoming season. I would welcome everyones thoughts on the radio situation. The way I see my interest in the hobby at this point is glow powered planes. In the future I can see myself getting into some acrobatics, and I have a great interest in warbirds. I would like suggestions on radios with these long term goals in mind. Is it possible to buy a radio that would be a good starter but allow for growth into my future interests? Thanks in advance!

Re:New Radio - 2006/12/24 15:41 Jim,

Welcome to the Club.

Your radio question is a good one.

There are four major manufacturer's of radios Futaba, Hitec, JR and Airtronics.

I use Futaba and that to me is the most popular radio system used in our club. Hitec is very similar.

JR and Airtonics are also good but I have no direct experience with them so my opinion is bias.

It is important to know that there are differences in the wiring of servos between Futaba/Hitec and JR/Airtronics.
Therefore servos that work with Futaba/Hitec cannot be used with JR/Airtronics. It was true about ten years ago and I think it still holds true.

The important part for me was to get a radio that was similar and compatible with what my Dad was using since I was flying with him to learn. A trainer cord and buddy box are necessary to learn at the club. I believe the club owns a futaba and JR buddy box and they are in the field box for your use. I don't think hitec buddy cords are compatible with futaba but I know there are guys in the club who have learned with hitec.

Computer radios allow you to trim and adjust your servos linkages more easily than a regular non computer set up. It's little more complicated on the radio programming but allot less fussing with servo connections and linkages on the plane. Computer radio's have come down in price and are a very affordable option for the entry flyer in my opinion and are customizable for your needs for many years. A Futaba model that I know of is the 6EXA, it offers allot of features at a good price. about 180 with four servos, battery, one receiver. You would need a trainer cord with it about 35 bucks, the futaba trainer plug changed a couple years ago and I think our club cord may be the older style.

All these items above address a radio at 72 Mhz. You will have to pick a channel when you order it , I recommend talking to Dave Satter our VP he may be able to give you an idea of the less used channel numbers for the club.

There are other more expense options including a new 2.4 Ghz computer radio that is on my wish list but that is a more advanced system and I do not know how to use a buddy box system with it. This system senses open channels and is being sold as the holy grail of noninterference, and I believe them. This system starts are 350 and it is called Spektrum DX7.


I too love warbirds, but I will tell you this, they require allot of skill to fly. A warbird is proabably a third or fourth plane after mastering a trainer and sportster style aircraft. They like to go fast, so you have to be ready for anything.
Patience is the key, don't try to fly beyond your capablity. The warbirds will humble you in a hurry, but when they go well it's a huge rush.

Good luck, hope this helps, if you have specific questions, just post them and I give you my two cents.

Re:New Radio - 2006/12/24 21:57 .Jim,

I just did a lot of research on this topic & thought I would share what I found.

I read the spec’s on the top brand, read review, checked some blogs, review what was selling used on rc universe and why, etc, etc. I asked a lot of question of current members as to what they had & why, I spoke to a few non KRC members.

I have been a Futaba man for years and currently fly on one. I started looking at Futaba and the 2 I liked where the used 9Z or the new 9C’s. On the upper end on price @ 499.00. The one thing I kept hearing was they were not very user friendly as far as programming is concerned. Since programming is new for me, my radios are 1991 vintage, I really didn’t want to spend hour reading the manual out at the fields to figuring out what needed to be adjusted. Many guys selling on rc universe openly said going back to JR or just too difficult to work with.

Several guys suggested I look at JR. One thing about JR is many other non JR servos work by just plugging it in. The JR is nice. It is much more user friendly with the on screen programming, and got good reviews. Of course, the one I liked was the JR 9303, real nice. But since I would want to get the fully synthesized TX & RX, that way I could select a frequency that Karl was not on & he would not have to wait on me those days we both are there and he could even fly at the same time as me, if he felt brave and had an extra plane. Lol. The fully synthesized lets you select almost any channel you want but cost @ 499.00. Nice, but I do not know if I could use all the capabilities in the next few years so I decided to look at the newest JR 7202. That, now, only come fully synthesized and has all the great JR programming. Price was a little nicer 329.00 and can use all the different servos out there, so I am told. I was convinced this was what I was going to buy. Heck, the Hanger 9 Ultra Stick I just bought had a full programming step by step set up from Horizon Hobby. My 1st programming job would be done for me, what a deal.

Then Jim Secrease had to bring in his brand new Spektrum radio (DX7 cost @ 350.00) and read the reviews and tell us all the things the testers tried to do to shot it down, screw it up & they could not affect that radio. Now I had to do more research. Thanks Jim. Well then Joe Hanson got one. He was very helpful because he was the only one that had said Futaba was not hard to program. He let me look at it, showed me all the programming features, walked me threw some of things he had done to set up his airplane and by the sound of everything he might be buying a few more receivers because of the way you can “model match” and we know Joe has several different plane & sets them all up just so. He complained that it didn’t have red stick, but was working to rectifying that. You should go read up on some of these things. It was impressive and it really does look like the Spektrum is just a different name on the box because it sure looks like the new JR 7202, right down to most of the on screen programming.

Well, I decided, and I think all the guys I was asking for opions & input are glad that I’m done, lol, I am going to order the Spektrum DX7. I think this 7 channel will do most everything I could need for now & should be some time before I need or want a 9 channel or more programming capability. I am waiting till the beginning of Feb 07 to see if we see a price drop, I doubt it but I don’t need it right now, sorry Karl, but I can still fly the red Falcon a bit longer.

I have included several links that can get you started.

Hope you find this helps.
