Does anyone know what reciever this radio takes ? It's Hobby People's
store brand made by Futaba....

Thanks,
Dave.

If it is FM any of the HiTec receivers for Futaba will work fine. If it is AM you will have to go with a FMA receiver if you want a double conversion receiver. It's been a while since I have seen one of them opened up but if I remember right it uses a lot of the same parts as a Futaba FGK inside.

I have (and still use) two of these Cirrus 900-FM 7-channel transmitters.They were built by Futaba for Hobby Shack in the mid 1980's ( a "house brand" radio). One was purchased new (as a complete set) from Hobby Shack in 1986. Because the original Cirrus receiver could not be made to comply with narrow band standards, I bought a Futaba FP-R127DF 7 channel receiver to use with the transmitter (which I had narrowbanded a little over two years ago). This past Fall, I acquired another of the transmitters and use it with a Tower Hobbles S3K 7-Channel DC FM (System 3000) receiver (also made by Futaba). (I also had this transmitter narrow banded this past Fall.)

Even though the Cirrus 900-FM radio came out in the mid-1980's, it remains my favorite of all time. While it's not a computer radio, it still offers more "bells and whistles" than most any other non-computer radio even today. With features including adjustable dual rates on aileron, elevator and rudder, built-in electronic mixing of V-tail, elevons or rudder/ailerons (also with dual rate capability), ability to read the receiver battery (under load) by hooking a jumper cable from the airplane charge jack to the transmitter and reading the flight pack directly on the transmitter battery meter (for "go"/"no go" capability), *electronic servo function reversing on the transmitter, and built-in trainer capability. While some features are not considered anything particularly innovative today, it was unusual to see all these features combined into a "house radio" from a mail order hobby company back then.

*"Electronic servo function reversing", as opposed to "servo reversing". The manual states, "This distinction is very important when using any of the mixers. The switches do not reverse a single servo in the mix mode. Instead they reverse the entire function. Please note that BOTH mixers may be used at the same time."

Quite innovative for the mid-1980's, and they still make excellent "sport radios" today. With proper "care and feeding", I still hope to get many more years of service from them.

....excellant ! I use some of the other Cirrus radios too, and they are good.
I took a chance and got a good deal on this one....the battery is weak.

Would you still happen to have the instructions for the complete radio system
you originally bought ?

Yes I do. I'll scan the pages and send them to you. PM me with the email address you'd like me to send them to.

Thanks, Jon....

....here's another Cirrus manual type radio that rivals the computer jobs. I think
this one is a newer model than the 900. I have two of these....they came with
the RD127DF reciever, with a Cirrus sticker on it.

I have recently aquired the exact same transmitter and I cannot figure out the "Electronic servo reversing." I've removed the rear cover but I don't want to touch anyting back there. Can you help me to understand how it works?

....these tiny switches are marked "normal" and "reversed". Use them to change the direction
of travel on a servo if necessary.

I had a futaba radio with those little switches once
lost two airplain's with it
pre flight
set the radio down to move the airplane on the runway
take off and the elevator was reversed
just a light tap on the bottom and the switch moved
only took two birds to figure out
never bought anouther futaba again
Im not saying there a bad brand
just if a girl don't treat you right ya move on

What an idiot I am........I didn't realize the front cover slides to the right and then comes off revealing the switches! I'm used to finding them on the back of the transmitters!
