Hello,

Returned recently: had a season of indoor/park flying and lately back onto a proper flying site/

I've a Multiplex trainer which is fine; simple five channel with differential ailerons.

Tx is Spektrum DX8 DSMX. Current rx is standard 6 channel spektrum

Many of the park fliers have had stabilisation: both helis and fixed wing. I'm impressed.

However, I'm really returning for scale interest, not interested in hot dogging or whatever, and certainly only interested in e-flight, so no huge scale gas or glow; I go fly the full size.

Having acquired a Durafly Stuka (I missed out on the larger FMS when some bod bought up the whole distributor stock one weekend), I'd like to try out a stabilisation system in it before progressing to a more sophisticated machine eg one of the FW190A's a little larger than this.

So eventually would prefer the usual three channels for throttle, rudder and elevator, with two channels for differential ailerons, one (Y lead) channel for flaps, and one channel for retracts. That's six actuating channels.

Having a Spektrum I naturally migrated to their AS3X. I now know that Orange and Yellow do compatible rx's with stabilisation.

Spektrum do a 6 channel, but don't remind you that one channel is to switch the stabilisation mode (well they do, but you have to dig). So that reduces it down to 5 active a/c controls. It's relatively affordable. Orange I haven't investigated too much, and Yellow do something restrictive in limiting channels when doing differential ailerons .... or something equally silly.

So it looks as though I'll need at least 7 channels (including the stab mode channel)

Spektrum do a 7 channel and indeed a 9 channel. They are approx. twice the price of the already uncheap 6 channel.

Should I contemplate Yellow or Orange or any other hue for that matter? Or should I even consider an add on stabilisation module over a standard rxer?

I should probably make a journey to one of the larger model shops Slough say, but not sure that I'd learn much more.

Oh, the current set up on the Stuka has throttle, rudder, elevator, and one channel each for (Y lead) ailerons, (Y lead) flaps, and (Y lead) Nav and landing lights. I could ditch the nav lights reducing the need to 5 channels, and free that 6th channel up for stab control, but that closes me off for expansion in a later model.

Any advice, recommendations I'd be most grateful

Robin, Lemon do a 7 channel dual aerial combined stabilsed receiver that is fuss free due to no extra cables and is

DSMX

Google Lemon, or Inwood Models

Personally, I tend to go for the separate stabiliser and standard Rx, no really major reason for this. I use FrSky and they have a stabilisation Rx (and very reasonably priced too), but I feel the separate module gives me more flexibility - it is also of course interchangable between models with swaping Rx's and re-binding etc. Just a thought.

Agreed BEB, the separate stabiliser can be connected to

Your favourite, bullet proof, trusted receiver, so is integrated with your trusted set up

Orange do a nice add on stabiliser for this, as well as other makers

My 1st successful attempt some time ago was using just one heading hold gyro on ailerons, very cheap to do

I have one of THESE as separate from the Rx . Works well

I would point out that the Lemon DSMX stabiliser Rx is 7 channel. Aux2 on the bind plug so you can have the normal 6 channels as well.

At $21.20 I think they are cheap enough to use permanently dedicated to individual planes.

I my experience transferring anything, particularly a gyro, requires significant testing to ensure the set up is correct and any disturbed connectors are sound.

I have CC3D flight controllers (six outputs, a little over £10 each) in a Parkzone Mosquito and a Multiplex Solius. More hassle to get going than an AS3X would be, but they work well.

The CC3D in the Mossie runs in rate mode and makes it feel like a bigger model.

The installation in the Solius was done out of curiosity as I had the Solius, an AR7700 and a CC3D doing nothing. One handed launches and hands free landings...

Well, that you all, that hugely helpful, provides food for thought and confidence in these suggestions.

I quite like the idea of the add on and even the Yellow/Orange comes with recommendations so despite their cheapness I've more confidence.

Not sure yet and some digging, but I do like differential ailerons, and need to understand how some achieve that, either in the TX, RX, or add-on module.

Brilliant helpfulness.

You can do differential aileron and flaperon / spoileron with the Lemon Stab+, but you must not select 'auto level' with these features enabled, apparently.

I've got a couple of these receivers and (for me) they work well enough as rate gyro's but (again, for me) not so well in auto level, so I just don't use auto level.

Another vote for the Lemon standard stabilised Rx. Extremely easy to use and adjust at the field. No laptops !😀😀. Switchable on/off ! Very useful when landing in a gale between trees as we have to !😣😣 Colin

For FrSky, the S6R and S8R stabilising receivers are only a couple of pounds more than the X6R and X8R. You may configure them with the stabilising function turned off, so I reckon you might as well always get them.

They may be configured from the Tx (assuming you are using ersky9x or openTx).

What are you looking for in the above Robin?

For fixed wing, there are cheaper and simpler options

This confused me Mike until I realised that they only work with FRSKY tx's.

The modes are comprehensive, probably more than anyone really needs, but attitude hold/wing levelling appeals for nice locked approach/finals

Why do you need differential ailerons, it's rarely a problem with basic models.

Easily done by the way by moving the servo output arm by one spline on each servo and lengthening the pushrod to compensate.

I would second an eagletree guardian. Separate unit, very customizable, much more effective that the Lemon stabiliser+, and it will allow dual aileron and aileron differential.
