Out of interest

[toto]

As it says ..... out of interest ........ is there a step change in favoured transmitters that would be best when starting to look at RC jets.

 

I only have the two freewing commercial jets .... the PJ50 and the AL 37 .... but if you were to intend flying military jets..... what do you need to consider when choosing a transmitter ......

Buying finger twitching again😉

[toto]

As if I very would ....... how date you even suggest ......

 

No .... I'm just wondering the more advanced features that a transmitter may .... or may not need ..... to operate a jet successfully with no compromises.

 

I do get your mindset though ......

Nope, use same radio as any other model. It's still an aeroplane whatever it's powered by. If you get into bigger, heavier turbine or EDF jets you might want more redundancy and more powerful servos but essentially the same radio.

[Philip Lewis 3]

EDF nothing special required but if you mean real jets i.e. jet turbines then probably most popular are Jeti and FrSky, principally because both offer 900 mhz alternative (868 mhz here in the UK and EU) frequency back up receiver options which in a multi thousand pound jet is considered essential, epecially in North America where they have been experiencing a lot of 2.4 ghz interference.

 

They will also both run LUA scripts which can display all the turbine data on the tx screen, there is a FrSky TX called the aerowing version which was designed in collaboration between FrSky and Global Jet Club.

Although most of my EDFs are on 2.4 Ghz I still fly one using a 25 year old 6ch Futaba Tx on 35 Meg! No positioning worries with its long Rx aerial just run all the way along the fuselage and up the fin. It works the servos just the same with a claimed out of sight range.

Of course very few people use 35Meg so being "shot down" by someone using the same frequency is no longer an issue.

[Paul De Tourtoulon]

I have heard of static problems on 2.4, I fly my turbine on 41 mhz firstly on my old Futaba FC-18, now on my Futaba FX-30, for over 20 years

 and it has never missed a beat, any std 8 channel radio will do the job, I have earthed the tail tube to the turbine, and none of that so called anti-static fuel.

@toto you wanting us to say you need an IX14? 🙂

Don't forget the buddy lead so he'll need two.

[toto]

For a change I'm not looking to be buying anything. I have an 8 channel transmitter which should do some basic EDF's but more interested in if that will be suitable to handle any concoction of channel mixing that may be required. Really just wanting to get my head around the basics. 

 

There won't be any stray concorde heading you way any time soon.

I use a DX9, for about the last 13 years. What you use for long term replacement should be your choice, made when you need it, and can probably work out what you need. A lot of the options also move round WHERE controls are on the trani. For instance, the 2 rear sliders on a Spectrum, are uncomfortably far round for my small  hands, my nex trani will have those sliders on the case sides. Not all electro in gimmickry. 
But, a Concorde.
Channels for, port motor, starboard motor, left aileron, right aileron, left flap, right flap, rudder, elevator, undercarriage. That’s a deluxe setup. 9 channels. Do the two motors on one channel, 8 channels. No difference in functionality. Do the two flaps on one channel, not much difference in functionality, just have to make sure the flaps are mechanically synchronised, add lights to your pleasures. Now remind me how many channels a NX8 has?

Apparently (with the latest firmware update) 20

Not sure edfs need any more channels than a conventional propeller driven model................ or more mixing or other electronic trickery.

 

As with most things, can be as complex or as simple as you want......

[Paul De Tourtoulon]

The Rafale needs,

1 two elevons

2 rudder,

3, front wheel steering

4, canard

5, retracts

6; Brakes

7, turbine throttle

8, optional air brake.

9, smoke on a gas turbine, an inadequate controller will suffice for an electric one.😄

 

A delta needs one less, no canards.

[GrumpyGnome]

My P47 has:

 

• Ailerons x 2
• Flaps x 2
• Undercarriage x 2
• Elevator
• Rudder
• Throttle
• Ignition kill

 

10 receiver outputs - I'm not a fan of Y-leads.

 

So I use:

 

• Switch for throttle hold
• Switch for ignition kill
• Switch for flaps
• Switch for undercarriage
• Switch for flight modes
• Switch to turn logging on/off
• Switch for timer reset & status
• Rotary dial for spoken alert volume 
• Plus the 2 sticks.

 

12 transmitter 'channels'.

 

At this rate toto'll want an IX20........

 

 

[toto]

I don't like the idea of Y leads but use them if necessary, ie if the NX 8 can't cope with number of channels but on the kind of models I currently own ..... no such problem so far.

 

The kind of jets that I would be likely to consider would be limited to EDF type models. I like the types as sold by Motion RC.

 

F4 Phantom

F 14 Tomcat

 

I don't think I need to say ....... not for right now .... but ...... not for right now. .... it won't stop me from buying them though ahead of time as usual.

 

If so ..... I'd like to do so in the knowledge that its not going to have any unintended further spend on other items ...... transmitters etc ...... the main reason for asking. 

 

I am also aware that these things have different approaches on how to fly and how your existing channels are used to provide the best control. All interesting stuff....... but streets ahead.

 

Now .......... where is my Tasman 

 

Toto

[Paul De Tourtoulon]

Nothing wrong with Y leads, or multiplex plugs with common + and - leads.

 Y leads They are all right if they are the 'proper ones'

 

 Forgot 40+ planes and only 5 receivers with more than 7 channels.

[GrumpyGnome]

I'm not a fan of Y-leads and will avoid them if I can. That's just my preference.  I didn't say "they're rubbish" or anything like that.......

[Martin Harris - Moderator]

I use separate channels rather than Y leads wherever possible.  I can instantly recall two occasions where this has saved my own models - although of course there’s the counter argument that it can double the chances of certain failure modes - although with a good chance of  retaining sufficient control to land.  This is on top of the flexibility of being able to fine tune the surfaces easily.

Most, if not all, Freewing EDf's use supplied control boards which do all the mixing & channel distributions. So the Phantom only uses 6 channels & the F14 can operate on either 7 channels or 9 if you add thrust reversing & gyro modes. The manuals are available on Motion's website (under the 'support' tabs), if you want to check requirements.

 

However that won't stop you wanting an IX20 or DS24 to operate it!!😀

[toto]

Hmmmmm ..... an issue I picked up on was a potential issue with the use of Spektrum Avian ESC's. Can't remember the exact detail but I suppose if you are buying PNP models .... that won't matter as they come supplied with their own brand.

 

Loads of potential pit falls if you don't do the homework.

Hey virgin here: my Futaba 14sg has dual receiver capability. Is there something different with the others, Jeti and FRSky ??

[Philip Lewis 3]

FrSky and Jeti dual receiver set up's control all of the channels all of the time and on two different frequencies with two separate RF transmission modules.   

[Frank Skilbeck]

Friend (no longer with us sadly) flew his 1/4 scale DH Vampire on a Dx8, he had to use a JR matchbox so he could couple and adjust some of the servos together.
