After some exhaustive reading and searching I still havent found what Iam looking for so here goes.
I need a custom built one channel radio(transmitter?) to fit in a tiny area. Any suggestions where I can get something like this? Thanks in advance for any help.

Can I ask what its for ? Single channel seems a bit of an oddball.

It is to fit in the handlebar of a motorcycle to transmit throttle control signals to the carb.

Now You have probably lost interest but I didnt want to be devious and claim it was for something that wasnt.

why not use a servo tester

Thanks for the suggestion darryl123, I checked out that link and if I understand the servo tester correctly it would require directly wiring to the servo. Iam in need of a wireless link between the throttle on the handlebars and the carb. because the inside of the handlebars are full of hidden hydraulics for brakes and clutch etc. Iam attempting to "clean up" the look by removing visible cables and wiring.

Hi,

Cannot help you for that single-channel-TX.
But I guess the biggest problem you'll have is to filter the interferences of the sparks of the glowplug(s) of your engine.

You might want to look at a 2.4 gig radio system -for interference free link up.
the exercize sounds a bit "busy"

the real problem would be getting any appreciable power to the carb -if you are trying to operate a needle or some such device .
So the servo and it's rx would likely occupy a block of about 1''x1"x2". pretty smallservo
or
From a purely technical standpoint the tiny servo tester setup from JR (Matchmaker $30.00)would be best -in that at the carb- a powerful/fast servo could be added -with no other components
in the radio setup you have to power both ends of the link.
The matchmaker has a small thumbscrew on one end which is fast and accurate -it measures about --1/2x1x2"
Those "servo testers "are huge by comparison.
IF you are trying for a custom showbike look - the rc link would be trick -but I sure would not want to ride it -

Thank You Dick Hanson for Your input, and the first positive sign this may be possible. Unfortunately You lost Me. I know a little about electronics but have never messed with radio control. Could You possibly put Your reply in dummy proof language? Carl

hang on, this is for a full scale ridable bike? there is absolutely no way that would ever be close to safe!!! if you plan on ever riding it again think about the entire thing for a second...

bikebuilder

Ok then, You have talked Me out of this idea if the thing will be unsafe in any way! Thanks all for Your input and time spent on my behalf.

There are some cars and many aircraft which have no direct mechanical link from operator to controlled devices
BUT as the throttle control-on a bike -tho it is possible it is not feasible --it is a very poor idea for one which is actually ridden.
reason is the number of possible failure points.
to dumb it down:
a controlled voltage to each the transmitting and the receiving device requires separate batteries OR wires -so you ar back to square one -on a strictly show bike (never ridden) - sure -cute gimmick.
no matter how small the transmitting unit -it would require some type rotary output (for the hand throttle) INTERFACE with the transmitted signal.
The receiver would also require a fairly strong rotary output servo-but wiring would not be a problem.
All in all tougher than it sounds -to get a good system . even then powering the TX would require some additional bulk in/on around the grip. and the failure risk -extremely high.
