Hi.
I am just about to restart my boating after many years and am in a
Quandary what to do regarding the radio .
I have found my old f14 tranny from years ago but minus any battery
Or receiver. I have been doing a search online and the receivers for 40 mgs
And battery seem to be unreasonably expensive these days compared to the
New sets . But I see quite a few people still use the 40 band
Am only starting will an assurance class tug build at the moment but most likely will progress from there ,
Question is do I stick with what i have which seems will be costly
Or go for a new setup from scratch.
I see you can still add more channels to the old f14 but again is more expense


Have always been a Futaba fan in the past but looking on HobbyKing there is so much more choice now ..
Any advice greatly received

[grendel]

bearing in mind you can get 2.4mhz sets relatively cheap nowadays (£30 upwards) which I have found perfectly adequate for my boats, I would go with the new option.
these are digitally bound between the receiver and transmitter, so no issues with interference or crystals or channels.

[malcolmfrary]

If the control requirements are fairly basic, a complete 2G4 outfit can be got for less than the cost of a single 40MHz receiver and crystals. 
The downside is that whereas 40 and 27MHz receivers from any maker would work with anybody elses transmitter, there is very little cross compatibility with 2G4. 
But currently, a 2G4 receiver that doesn't need crystals from HobbyKing costs less than a pair of crystals, and that is IF you can find the crystals.

Personally I'd convert the F14 to 2.4ghz with an frsky module. They're easy to do, allow you to retain the 40mhz module if you want to by using a switch, and use cheap frsky receivers


Here's an 8ch version:

did you miss the attachment..lol


i did consider going the conversion as it would allow me to add a couple of switches to the board fairly easily from what i have read.
Just unsure what or best place to get said items.
Although i'm not that proficient with electronics i might need some guidance.


with regards to a completely new setup  i have been looking at
TURNIGY TGY-I6 AFHDS TRANSMITTER AND 6CH RECEIVER (MODE 2)
or
[/size]TURNIGY 9X 9CH TRANSMITTER W/ MODULE & IA8 RECEIVER (MODE 1) (AFHDS 2A SYSTEM)
or something in this region .. but reading up on reviews on and online comments there seem to be issues of one kind or another with their opperating systems
so although the new computer trannys have appeal seem to carry their own problems with bugs.

[Keith.E]

me bad..


put me glasses on.. yes have it now.

[Keith.E]

Having read through the instructions and on utube and looking on my old tx its not a simple plug in as i have one of the earlie ones
with a different circuit boards and have no trainer socket to plug it into so think ill give that a miss as im not good enough to mess about with electronics.

[Keith.E]

i have found these receivers in 40 mhz has anyone had any experience with these

just trying to find a few inexpensive options

I and several others on the forum have the TGY i6 system. The only issue I have with it is that you have to use the Cancel button to save items when programming. For simple boat use I don't think you will have any problems. Receivers are cheap - you can use Flysky ones which are the same as the Turnigy ones.

just trying to find a few inexpensive options
these need smaller xtrals if i remember correctly,

I use these https://www.ebay.co.uk/itm/Corona-RP6D1-6ch-40MHz-Dual-Conversion-Receiver-For-Futaba-JR-PPM-Receiver/192259858603?hash=item2cc394a0ab:g:xgEAAOSwePhZemQW

but they don't work with the add on modules.

[Keith.E]

ive ordered one of these up for now and see how i go..
https://hobbyking.com/en_us/corona-synthesized-receiver-4ch-40mhz-v2.html
if it does'nt work out ill sell the f14 as im sure there are others about that would get use from it
and go the 2.4 route.. just wanted to try to get it usable as its one of the only more  boat orientated tx's out there

[timgarrod]

should be fine with this. have a couple 

[tsenecal]

Keith,


not really an answer for you....   


I recently converted my robbe fc-28 to 2.4ghz, using Corona parts, and i have had zero issues regarding that kit.  hopefully the 40mhz equipment is as nicely built as their 2.4ghz stuff.


one question i have for you regarding your f14...  do you use any of the multi-prop or multi-switch expansion boards?

[Keith.E]

If I can get the f14 working either by the new reciever of a conversion I was going to add at least a couple of toggle switches . I have the older version which only has the 7 channels sockets and the options socket for the multi switches or sliders .

[RST]

...Have to say, after a long break and a fellow F-14 user whilst everyone else is converting to 2.4ghz I've found it refreshing to snaffle up 3 and 4 channel single conversion 40meg receivers on EBay UK for about £5-10 buy it now (most new -BNIB).  You can get any 40meg xtal pairs for about £2.50'odd, plus pennies poisted.
F14 is single conversion -so it won't work with dual conversion receivers.
...I love my F14 set-I butchered my set to give home brew dual rates, converted available analogue channels into switched others. 

For £5-10 for a 3 or 4 channel 40mhz receiver from a UK seller these days + £2.50 for a pair of xtals on the ebay, I wouldn't discount the F14 just yet as it is!

[Keith.E]

i know its been a few years since i last had my f14 in the daylight and do not have either the origional rx or instruction book, but i was under the impression that it used duel conversion receivers.. or is it that old..
i know the new ones out now do.. maybe thats what is throwing me



mine is the 4/ 7 channel version expandable, think i purchased it back in early 90's i guess it must be now.. but i thought it was duel conversion.


maybe im mixing it up with my old ff6 tranny i have for my planes..

Its only the receiver that is dual conversion, the transmitter sends exactly the same signal.  The receiver does need a different crystal as opposed to normal, single conversion.  If going 2G4, it is a different story.

[Keith.E]

after much searching i have found a wiring diagram of the circuit board in my particular f14 which is different slightly from the newer ones


http://www.rc-network.de/magazin/artikel_03/art_03-0069/art_03-0069-03.html


this is for a trainer line hack but basically confirms what i has suspected in that this multi opp socket carries the same wireing as the trainer socket but in slightly different positions within the socket.


so basically i could convert this fairly easily if i wanted by seems of it.. which i am tempted to do .. best of both as i do quite like my ol f14 tx

[tsenecal]

if you plan on upgrading your f14 to 2.4ghz, i recommend this as a guide to do it.

can anyone advise if this
https://hobbyking.com/en_us/3-way-position-switch-for-fs-i4x-short-actuator.html


does the same as this
http://www.ripmax.com/Item.aspx?ItemID=P-RT1600


massive price difference if it is basically the same..


specially as im after 2 add switched channels to add to my f14

[Keith.E]

Just an update relay though I know it's been a few months or so


I managed to get a couple of corona synthesized receivers on 40mgz then found they were slowly to be discontinued .. something to do with manufacturing supply stopped due to not enough supply


Anyhow I ordered up the corona 2.4 diy kit which comes with an 8 channel receiver.
Equipped with kit and a dpd switch soldered it in ,,the result is I now have a radio switchable between 2.4 and 40 meg ..


Have tested both and all working as it should.


Only question is would insurance recognise such a kit fitted to a radio and would a model boating club allow use of said conversion .. Just wondered .

[DaveM]

I suspect that the first part of the question could only be answered by your insurance company, although I very much doubt that any insurance company would either know or care about the difference. If the answer is in the afirmative then the second part becomes redundant. Insurance is, after all, insurance.
