Hi,

I've came across the Supreme IIS (Hitec receiver), they say that I could use it with my 6EXA from Futaba, do you guy already try it, will this work? Because the receiver and crystal are way more expensive in futaba then Hitec.

Thanks

Yes it will work, I use them all the time.
I make the assumption your Futaba is 72Mhz and not the new 2.4Ghz.

it requires crystal which makes it almost the same price as tower hobbies receiver which compatible with futaba and includes crystal.

And, in case you didn't know, Tower radio gear is made by Futaba.

Personally, I think Hitec makes a better RX than Futaba (or most anyone else), but that's based only on my own experiences and personal bias. Lots of people disagree, and that's fine.

I fly Hitec Supreme receivers with my Futaba 7C. I also fly the GWS RD8SL receiver available from Hobby City for $24.99 plus $3.99 for the crystal. This receiver (I own three) works wonderfully with my Futaba radio but is also shift selectable and will work equally well with JR or Airtronics transmitters.

The RD8SL is a full range, dual conversion receiver just like the Hitec Supreme IIS or Futaba R168DF. Two receivers and two crystals are just under the maximum weight for $5 shipping. Because of this outstanding value, Hobby City is frequently backordered, but they get them in all the time.

If you want a great receiver value for your 72Mhz FM radio, this is it. I'm flying my King Kobra with this receiver.

biged,
let me understand is this receiver in the links/picture works with futaba Tx?
how about servos, does futaba or tower hobbies servos match this receiver?
what about this one: http://www.hobbycity.com/hobbycity/s...idProduct=4478
did you try it?

Thanks
Alex

The GWS RD8SL receiver I mentioned is completely compatible with all brands of standard size servos. I'm at work right now, so I can't look at one to see if it will accept the Futaba servo tab on the connector. Worst case, you might have to clip the little tab off your Futaba servos to connect them, but I'll look for sure when I get home.

I'm using RD8SL with Hitec HS425BBs in my Sig King Kobra. JR, Hobbico, Cirrus, or Airtronic servos would also plug right in.

The smaller Pico and Nano series receivers, like the one you linked to, are sold in seperate "F" or "J" types for negative or positive shift on 72Mhz. I have several GWS Pico and Naro receivers that are "F" (as in Futaba, negative shift) that work wonderfully with my Futaba transmitter, the 7CAP. This are single conversion receivers with shorter antennas that are intended for shorter range park flyer applications.

Last I looked, Hobby City was only stocking the J/JR/Positive Shift type Pico and Naro receivers for 72Mhz, and not the Futaba compatible F models. These models also use the single conversion rather than dual conversion crystals.

My local HobbyTown USA stocks the GWS Pico and Naro receivers and charges a whopping $19.99 and $26.99 for the 4-channel and 6-channel versions respectively. Come to think of it, I'm not sure I know of anywhere that sells hobby goods that doesn't stock at least some GWS components. They're not always super high performance, but GWS products are always good, reliable, and inexpensive compared to most other brands.

I probably wouldn't have been willing to try a $24.99 full range receiver on a glow plane, but I'd had such good luck with GWS' micro receivers that I figured their full range models had to be at least as good as the small ones.

Tower Hobbies carries the F and J types of Pico and Naro micro receivers:

...and crystal:

They also carry a budget receiver by Hitec called the Mini 6S. The Hitec Mini 6S is a single conversion model that is designed for full range flying. It is also shift selectable like the GWS RS8DL so you don't have to worry about shopping for a Futaba/Tower/Hitec or JR/Airtronics model, it will work with both. The Mini 6S is actually an auto-shift receiver that detects your radio signal type and switches automatically.

...and crystal:

At $36 for receiver plus crystal, this would probably be a pretty good choice for anyone looking for a budget receiver that didn't want to order the GWS model from Hong Kong. I personally have never used the Mini 6S before, but I like Hitec's receiver products and I'd try one of this out in the right project.

For a sport plane or trainer, the Mini 6S by Hitec would probably prove to be a good, reliable receiver for any kind of 72Mhz FM radio system. It has the tab slots to accept Futaba servo connectors, as well.

With the Hitec Supreme IIS available for just $12 more, however, most pilots prefer to opt for the Dual Conversion model with two extra channels on it.

Thanks BigEd,
im budgeting something here before i'll brake one of my kit built Sig stars...
i just want a trainer like TT easytriner 40H ARF, just to have a trainer with 46 pro
i have a free 2.4 GHz reciever which is designated for 4*60.
its not important, just thinking.

I'm with Big Ed. I fly with a Futaba 9 cap and have all 16+ hitec receivers. Actually, I do own a futaba receiver, but it's not even in a plane.

For the record, I looked at my GWS RD8SL receivers and they have the slots for the Futaba connectors on them.

I have a couple of R127DF receivers and even a PCM R138DP. I like Futaba receivers just fine, but not so well that I'm willing to pay $72.98 for a receiver and crystal.

One of the R127DFs came with my 7CAP, while the other came with an Easy Sport I bought. I bought a 7CHP radio system and sold the transmitter, so I got the R138DP w/ crystal, 1000Mah RX battery, four S3151 digital servos, switch, and servo extension all for about $113 net cost.

My attitude is basically that Futaba makes great receivers, and if you can pick one up without getting scalped, then by golly go ahead and get one! If your options are to pay regular price for a Futaba receiver and crystal or to get something else that is just as good for less, then you should probably save your money.

Considering Futaba pays you $3.00 to take a 4YF Transmitter w/ TX crystal, TX battery, frequency flag set, and wall charger instead of just buying a flight pack and receiver crystal without the transmitter, it just makes more sense to buy a whole radio system and part it out than to buy seperate Futaba radio components as you need them. I like Futaba transmitters, receivers, and servos but Futaba's pricing structure simply defies logic.

Thanks guys!!!

That really helpfull, now I can save a couple of $$$ on a Rx and crystal!

For the servos... in Futaba compatible, what do you use? Because I'm currently using S3004 but at 14,99$ca each [link=http://www.greathobbies.com/productinfo/?prod_id=FUTS3004]here, where it's the less expensive for me[/link] , I'd like to save a little bit more [sm=tongue_smile.gif]

Personally, I also like Hitec servos. If you want cheap, their basic bushed standard servo is usually around $10, sometimes as low as $8.99 on sale if you shop around. Springing for the HS-425 gets you a much better quality servo at roughtly the same cost as the bottom of the line Futaba's.

I also am going away from the futaba sevos and recievers and going to hitec. The reason being for one is price and the hitec servos are built stonger for less money. The 3004 futaba servos only have plastic gear trains in them.

Nothing wrong with nylon gears in many applications. In fact, in smaller models, up to about 60 size, in most applications, nylon gears are going to give you better performance. Metal gears have more backlash than nylon, so the nylon gears will give you a tighter control system. It's only when you start putting enough stress in the control surfaces to strip the nylon gears in flight will metal gears really make sense. (of course, if you crash a lot, you might save money. Nylon gear sets are only $2-$3 each usually, but it still adds up if you crash often enough ).

The Hobbico receivers also look like Futaba receivers and are $10 less.

The Tower and Hobbico receivers are actually $22.99 less than the comparable Futaba FM receivers. The Tower Hobbies and Hobbico receivers come with the receiver crystal provided and are $49.99. The Futaba receivers are $59.99 without the receiver crystal and crystals are an additional $12.99 each.

As I've said previously, the pricing scheme for Futaba radio accessories mystifies me and paying regular price for a Futaba receiver and crystal isn't an option I'd choose. There are too many perfectly good alternatives that are far less expensive.

Forgot about the crystals. Don't think I would pay for Futaba stuff, either, in the future.

I'm not saying "Don't buy Futaba," I'm just saying be smart about it. Buy a 4YF and sell or auction off the transmitter with tx battery, charger, and manual. You'll save $3 plus whatever you get for the transmitter. The example I gave where I bought the 7CHP radio system and sold off the Transmitter is a good example of how to get top quality radio gear for way less than retail.

Futaba receivers and servos are great quality, you just have to work a little harder to get a good deal on them. If you don't want to take the extra steps, then Hitec, Tower, and Hobbico branded radio accessories are all excellent, lower-cost alternatives. There's no such thing as a discount PCM receiver though, so figuring out how best to part out Futaba radio systems is also a good alternative.
