Default What reciever to buy?

I've got a Futaba Conquest FM FP-T4NBF radio on channel 28. Could somebody tell me if all futaba fm lo recievers will work with this and also would a hitech reciever on the same channel 28 be a good option.I'm not much on this subject and I hav'nt flown an airplane in over ten years so I'm not up on all this and also, is 28 a good channel these days or is it subject to getting hitts. I just bought new tx & rx batterys and four servo's for this radio and all I need know is a reciever. I know I sound crazy spending all this money on this radio but it was my Dads before he passed away and we used to fly together so I really want to get it working again. Any help on this matter would be very much appreciated. Thanks. Gary.

Any non PCM Futaba RX on the low band will work with this TX. I have had great success with the Hitec 555 receiver, it's small and works real well. Check with the club in your area about the channel and it's history of hits. They will know which channels are to be avoided in your area.

Personally I like the hitec brand and have had great success. The 555's are more expensive that the standard 7 channel universal. because they are smaller. They also only have 4 channels. My smaller planes use these.

If cost is an issue Hobbico sells one (it's identical to the Futaba brand, just a different name, from what my LHS has advised and what I've read online). Same price as a Hitec 7 channel but it includes the crystal.

I prefer the Hitec or Futaba brands but it's strictly a personal preference.

Gary:

I don't know how old your Conquest transmitter is - but from what you say there is a good chance that it hasn't been narrow banded. In that case, you may think that you are on channel 28, but it could spill over into 27 and 29 and shoot some other innocent person out of the air. So - confirm it has been narrow banded. If not - relegate it to the scrap heap now! It's not worth the price of conversion.

It is gold stickered , that I know. I think when this radio came out, the tx was and the rx was not. believe me, I know all about flying safety and would never use unsafe equipment to fly with. Know that I can chat with all you experts out there, which radio is considered the safest these days. And let me say this, this internet stuff sure is neat ain't it. I sure wish I had all you experts to talk with back when I first started flying. Spill your brains out for me, Please.

A very good source for after market recievers is FMA. They will mate up with any of the major brands and have excellent range and better than most for sensitivity and noise rejection. Check out FMAdirect.com for details.

That's funny, my 555 has 5 channels. Do you think 555 has some meaning?

Hi Vince,

yes it has 5 channels but the 5th is used only if you want to share the battery with a servo e.g. the throttle.

I'm supersticious and always give the battery it's own connection.

The 555 is a hitec number just like the 425 or 525 servos. Unless now you're gonna tell me that the 525 has 525 oz of torque

Now that would be a servo

The battery is on the same power rail on the circuit board as the + and - leads of all the servos, it makes absolutely no differance where you plug it in.

I was of the impression that the receiver and transmitter had to be "tuned" to each other. So unless everyone who mixes and matches the equipment brands sends them in for tuning, I am now getting the impression that it really doesn't make a bit of difference whether they get "tuned" or not.

hmmmmmmmmmmm???

The way I understand it is that the TRANSMITTER's frequency module electronics need to be tuned to it's crystal. It's OK to swap out entire modules but not OK to change individual crystals.

RECEIVERS however do not need to be so finely tuned; therefore you are allowed to change crystals.

I believe the reasoning is that out of tune transmitters can interfere with other channels and other planes but an out of tune receiver won't cause interference because it doesn't SEND out any signals.

The exception being you can't mix a PCM receiver with a non-PCM transmitter. Some transmitters however, can be either PCM or plain FM (non-PCM) so those may be used with both types of receivers.

Default tuning

Well that seems logical. That's the best explanation I have heard so far.

Maybe I will can post to one of the manufacturer forums and see if they concur.

Thanks

Oh, one more note. The transmitter and module must be the same brand to be FCC legal. Although a Hitec module may work in a Futaba transmitter for example, the pair aren't perfectly tuned to each other and could potentially cause problems with adjacent channels. I've never heard of that happening but I'm rather new to the hobby. No matter, it's illegal to mix brands that way and if anything happens you could be held responsible and the AMA has grounds to refuse any insurance coverage.

Just my .02 worth,

C.P.

Default Not sure about that one

From what I understand, there is nothing outside the module unit on the TX that needs any tuning. That is why you can send just the module unit in and not the whole transmitter.

Whether or not people use different branded modules is an interesting question though.
