Waterhouse & Eley Superfly perhaps?
Sorry, on my phone ATM, so can't search for a picture.
Kim
Eta just noticed that you'd discounted the Superfly - please ignore 😚

In my experience, it's important to have a metre or more distance between the tx and rx when binding the RX8R.
They're also prone to swamping if you're too close to the model when testing/setting up, giving nuisance 'telemetry lost ' announcements.
I've heard that the uni firmware doesn't do this - Mike??

I find it needs rudder to do good turns (drags it’s tail in turns) and of course it takes a beating on the ground.

I've set some aileron differential on mine, from memory about 1.5 times as much up deflection as down. This makes it turn in a more balanced way by decreasing the tendency for adverse yaw.
Or use the rudder 😀

I can't remember which sim you've got, Toto, but in mine (Phoenix V6) there is a setting called (iirc) 'keep ground in view'. Maybe yours has it too, or something like it.
For me, that overcomes the issue I think you're describing of effectively getting 'lost' and losing the orientation between the 'plane and the strip / field.
I'm back on the sim now myself, because 1. I've only been able to fly my 'planes once since the beginning of December, due to weather mainly.
And 2. Having reached my 'three score years and ten' I've just bought my first helicopter (a nib but very old Blade 400) and need to practice before committing aviation with it.
What could possibly go wrong?? 😱

I have used a few Lemon Rx, both stabilised and conventional flavours.
Have I had an unexplained crash - yes - but the Tx was later found to be faulty, so in retrospect, I don't think that the Lemon was at fault.
Now that I have a new (multi protocol) Tx, I may well dig it out of the drawer (I never throw anything away - why?) and give it a thorough check before trying it out on a cheap foamy.
I would have no hesitation in using Lemon rx in the future, the Gen2 stabilised in particular, but will probably also use an additional satellite rx, particularly in larger planes.
Also the Lemon Rx designer is active over on the RCGroups forum (username fmak) and he seems very pro-active if there is any chance of a faulty unit, which does inspire some confidence.
Kim
p.s. I'm also thinking of getting a Lemon tx module for my Taranis, to use it as a back up to my Radiomaster TX16S Mk2 on the DSMX protocol 'just in case'

It'll probably be a 'wrap' - the image screen printed on to self adhesive vinyl.
Looks good nonetheless.

Don't know what happened there-lost all of the long post that went with it
Anyway it's a Nordec 10cc out of a rtp racing car as raced by my dad back in the day.
The Nordec was produced in Whyteleafe in Surrey and was a copy of the McCoy of the time.
This is a very rate (possibly unique) Mk2 Team Special which was a serious redesign and had much more power.
I rescued it from my dad's shed after he passed away and hope one day to get it running.

Because you're using it as a size comparison.

so what they are saying is theres no physical room to fit something like Spektrums Sky ID unit which a slight bit bigger than an oxo cube???? maybe a slightly smaller battery may help certainly with electric models
How big are the oxo cubes you buy?
This unit is nearly 1.5" square.
You undermine any argument you are trying to make by posting nonsense such as this.

Tricky isnt it ?
Havent had many Sea Furies mentioned , which surprises me as its... British , cool ,fast but practical . (just saying )
The twin thing is interesting .
I'd find a Sea Fury difficult to ignore, as my dad was on these when he was in the FAA, and they've also been a favourite on the airshow circuit.😎
Similarly, a Beaufighter would be another I'd struggle to pass over, as my friend / mentor when I first started r/c back in the late 70's flew them during WW2.
I can see why the layout could be a problem, though.
Keeping a watching brief.....................................................

I thought he wasn't allowed anything sharp, or the nurse gets nervous.
But seriously, I'd love one of these - nearly finished my Spitfire and will need something to do with my hands!!
Hopefully I can re-organise some funds when the time comes.

All I can add is that the invoice related to my recent order clearly shows the prices as being 'including tax' and the correct amount for a VAT element is shown separately at the bottom, as required by law in this country, I believe.
There is NO question in my mind that there is any kind of skulduggery going on, my guess is that the UK address is some kind of bonded warehouse, where the necessary systems are in place to pay the taxes due on the items as they pass through.

Pleased you've got it sorted, unfortunately your experience with the module confirms others experiences with Jumpers patchy build quality.
While transitioning to FrSky I used an iRangeX IRX4 Plus multi module for DSMX which was rock solid and very well built, only available secondhand now I think.
Still showing as available on Banggood, but tbh I've always been nervous about ordering from them. I do really want to get one of these, though.
I'll take on board the experience suffered by Brian as well as your observations regarding Jumper quality issues.
There is a Radiomaster external 4 in 1 module which sometimes seems to be available also, although until now I'd assumed that all of them were badge engineered and made in the same factory - maybe not!
Kim

Have you tried clicking on SBUS, to see if it opens up a sub menu of protocols?
As I said before, I'm as in the dark as you.
Bad show from Jumper, having out of date info on the website (just checked, it's still showing the 'old' type).

Hi Brian,
Has the module got a rotary selector switch on it, and if so is it set to '0'.
This allows the tx to communicate with the module via Serial connection.
Kim
Beyond that, I'm stumped.
e.t.a. I'm interested in the outcome / operation of the above combo, as I'm considering getting a MPM to fit in my own X9D+ 2019 as a backup for my Radiomaster TX16S MkII

IF it's the 'Lite' version with the built up wing - I built one of these (still have it but converted to electric power) and fitted an ASP61 4/.
It flew it very nicely indeed, easily enough for me, although I'm no aero whizz.
If it's the original kit with foam wing, then maybe a .70 or more, but the weight will be creeping up if you go much bigger.
Kim
eta forgot to say, I used 12x6 or 12x8 prop on the .61, sorry, cant remember which.
-
For my money, you need to pull the aerials back through the holes until just the 'active' bits are showing outside, maybe tuck the excess away inside the fuselage.
At the moment, the aerials are effectively parallel with each other, rather than at 90 degrees which is the ideal.

Maybe I should just call it a day and 4un the set up I have with the 6s batteries.
If that potentially fits the bill then let's leave it at that.
Toto
Toto,
The 500kV motor on a 6s will be VERY similar in performance (i.e. absorbed power) to an 800kV on 4s (assuming same prop). That's the beauty and flexibility of 'lectrics.
Just be sure to run everything through the wattmeter to make sure that you're not overloading motor or esc.
Kim
p.s. If you go back to (I think) page 1 of your Domino thread, I suggested a 4250 800kV for 4 cell or the same at 500kV for 6 cell. Either way, it'll work.

What prop would need to be fitted with the 4s then.
I have around a dozen 6s batteries so no worries as long as it is jot going to create any issue.
Toto
Okley dokey, I've looked on the Domino thread, and if I'm not mistaken, the motor is a 40mm can 500kV. That motor is going to need a lot of prop to give you (say) 700 - 750W on a 4s lipo. I think you'll run into clearance issues.
As you've got the 6s 'in stock' then I'd be inclined to give them a go, while being mindful of the extra weight and ensuring that you don't add more ballast to get it balanced.
In other words - make sure that the battery is placed at the optimum position to give the correct c of g (or as near as possible) without adding extra unnecessary weight.
Or - and I'm only now as I'm typing thinking of this - you could try a 3 blade prop to give a bit more oomph. Maybe someone with access to Ecalc could run the numbers for you on a 12x8 or 13x8 3 blade??
Either way, with a bit of fiddling and experimentation, you'll have it flying nicely.

Royal Mail won't take lipo batteries unless contained within electronic equipment. Hobbyking will get a severe talking to when they're found out.
That's what I thought - but in this case, I'm not complaining.😉

Hi Kim,
I'll check out the potor and prop sizes and come back to you. What I do know is it's a 60amp ESC and 4s 5000 man battery.
Cheers
Toto
Well assuming that the motor is capable of 50A or a little more, then you should be able to prop it to give 700W easily enough, which would be more than enough at the moment, I would have thought.
Your choice though - as you're finding out, there's always more than one way of skinning a cat, or powering a model 'plane, and neither is more 'right' or 'wrong'!!

Well a great day today.
On my next visit I will take my 6s batteries though as opposed to the 4s I took today as the model seemed a bit underpowered. At times it seemed it only had enough power to " float " through the air rather than " cut " through it.
Toto
Hi Toto
Good to hear you've had a positive experience.
I don't know what prop/esc/motor you've got in the Domino (could look it up on the thread, but too lazy) but you may only need to prop it up a bit, if you've got headroom on the esc/motor. Your wattmeter will tell you if you can or not.
If you do go to 6s, as per Aidan's advice, check c of g and also the watts being absorbed, to protect the esc/motor.
Happy flying
Kim
eta: Good also that you've had the weather - it's been unflyable down here for a fortnight or more.

Lipo's arrived by Royal Mail this morning - dispatched yesterday, so very surprised to see them and lucky I was in. 😀

Max Riot 3s or 4s

I fly my Riot on 3s3200 lipos and find it flies very nicely. Not fast by any means, but with the throws increased, very maneuverable.
Tbh they're a bit of a brick, so going fast is never going to be its strong suit.
Others may well disagree, of course.
