R136c Me Forgot Password? Nov 27, Can anyone please help, they are very precious to him and it will mean alot for both of us. Images View all Images in thread. If both units are working properly, powered properly, and the correct crystals are installed in both, the r1366f will react to the transmitter’s commands.
No binding procedure involved. Thanks EloyM, i was really hoping to see a reply yeh, i got in this hobby a few years a go, so i know nothing about this radio. Nov 28, Have you checked the battery voltages.
I would be surprised if the supplied batteries are capable of holding a charge. Also examine the plugs and wiring for corrosion. You say the tx is working- how do you know? Nov 29, When I mentioned checking the leads and plugs for corrosion, I should have said the battery leads and plugs. In the case of old nicad or nimh cells it is not unusual to find the negative lead to have bad corrosion.
However looking at the photos of your tx I realise that it is probably powered by dry cellsin which case my comments do not apply.
As far as the tx crystal is concerned, YES it is definitely missing from the board. I can’t thank you both enough, you were patient and kind to answer me.
Dec 02, I believe that radio was made to be very versatile so possibly that could be one of the pre I would try out all the suggestions listed above, those are good starts. I would also check the following: Not to worry, possibly. Now to make things a little more complicated: Try this link, if it doesn’t work, then google-search “Futaba 6EXAP” and you should be able to find the manual s and more info.
Good Luck – Paul. Last edited by Pauliwog; Dec 02, at Dec 03, If the Tx and Rx worked together previously then it is probably a 35 Mhz system. It looks like the Tx crystal has been removed at some stage so open up the Rx crystal cover and remove the crystal – if it is a Futaba crystal it should have a label with the type dual or single conversion and frequency shown on it.
Get a Tx crystal on the same frequency, fit it and all should be good! Have a look here at their Futaba product page and scroll down to nearly the bottom of the listing where crystals are shown. I still have lots of catalogs, manuals and tech date for the pre Since this one is not so labeled, it is safe to vutaba it is Single Conversion SC. It futabaa dates it as being pre-DC.
The reference to DC transmitters is completely wrong – there is no such thing. DC conversion technology is only applies to RXs.
It refers to the mixing that is done to the original crystal r136c to arrive at the operating frequency. The photo of the receivers shows what may be a plug-in crystal on the top left corner. If a plug it, it may be labeled with a Channel Number and Frequency, which will tell you what similar frequency crystal is required for the Tx.
It may also be a bump on the Rx case to cover a soldered in crystals higher than the other components. If so, it will probably not be tagged, but will have some numbers etched on the top or printed on the side that will tell its frequency.
In many cases, some countries do not bother and flyers use the equipment most readily available. In your case, it is Europe, where most countries are allowed 35 MHz equipment. If you come up with some crystals numbers and needed help decoding them, let me know. Transmitters may use crystals on the final operating frequency, but more often at half, or some sub-multiple frequency that is multiplied to arrive at the final frequency.
It is called frequency multiplying, different from frequency conversion used in Rxs. You will never see a catalog or manual reference to a DC transmitter.
The TX’s crystal may in some cases be located close to the battery, but there is no technical reason to futab so.
More often it will be far away. In this case, looking at the photo, it appears there is a commonly used two-pin crystal holder installed at very top of the board.
