Do not take things for granted
Kim Taylor replied to Chris Freeman 3's topic in All Things Model Flying
Wouldn't a lipo fire melt sheet aluminium? Not trying to criticise, I don't know the answer, just a gut feeling Kim -
Don't know what the DSM refers to, but I've got mine bound to my Radiomaster TX16S Mk11 4 in 1 module using the V761 protocol (iirc). Works fine. Kim

Synchronised crashes -- coincidence or not?
Kim Taylor replied to Allan Bennett's topic in Incident Reports
Chris I believe that the commands are broadcast simultaneously on 2.4GHz and 900MHz, at least that's what the blurb on the T9 site says, in particular referancing the FrSky X18 Kim -
Synchronised crashes -- coincidence or not?
Kim Taylor replied to Allan Bennett's topic in Incident Reports
Getting back to the original question, let me relate a recent experience: I was flying my Kyosho Calmato Sport (so a fairly weighty balsa plane) when I suddenly felt that the model was doing 'odd' stuff, just not responding to the controls as I was expecting. Suspecting some kind of radio issue, I landed immediately, and only then noticed a filthy black cloud (like something out of a Harry Potter film) churning it's way across the field, closely followed by really strong, squally winds. Checked out on the ground, the model was flown later with no problems. So, is it possible that wind shear could cause the simultaneous events? Kim -

Not sure, I don't think so. I'm going to get one of the FrSky X series tx's which run 2.4GHz/900MHz rf modules simultaneously. Jeti do something similar, as do other, mainly higher end, manufacturers. Can't afford them, though 😐 Kim -

Maybe where Konrad operates, which seems to be in the USA, most of his peers are moving towards dual band equipment. I know that my (in southern UK) next tx purchase will be dual band, unless ELRS becomes predominant in the next 12 months. Kim -

Many current gen OpenTX and EdgeTX transmitters have a 2.4GHz scanner function. Taranis 2019 tx's and Radiomaster TX16S Mk11 certainly do - I have both. Kim -
I had a similar problem a few years ago which transpired to be my unconsciously closing one eye. In my case this was caused by surgery to remove a carcinoma in my temple, which left me with a 'droopy' eyelid. Since corrected with cosmetic surgery, but I have to consciously open my left eye to maintain depth perception. Maybe if you've got a bit of an imbalance in your eyes, something similar is happening.

When I saw that shot on the Best of British thread, I'd assumed that it was a composite, so very well done to the photographer 👍 Kim

Finally maidened my Calmato this morning. No dramas, couple of clicks of up elevator had it flying hands off, very smooth and stable. Needs the aileron throw increasing for my taste, but that's maybe just me. Had a bit of vibration at higher throttle, which may be due to the spinner being unbalanced - I've done the prop, so confident it's not that, but decided not to fly it again, until I've investigated. All in all, very pleased! 😋 Kim

Forgive me if I'm misunderstanding, but if you've 'got ' SAFE, then you should have AS3X too, assuming that you have the correct channels/ switches assigned on the tx. Have you got a 'panic ' button, and if so, is it working in the correct sense? In the past, I've had to reverse the panic button on my DX8g2, although that was with an older version of SAFE. It overrides everything else until it's corrected.
-
Can't really help you with why your tx won't update, other than to say that problems are usually down to the sd card being faulty or unsuitable. The AS3X should work regardless of the firmware installed on the tx, although to update or change settings within the rx you will need a firmware version which supports forward programming. If AS3X is actually doing nothing, either the rx is faulty (unlikely) or you haven't got the tx set up correctly. Just thought, you've given the throttle a 'blip' haven't you. AS3X doesn't arm until the throttle has passed 25% initially. Kim

I think that the design has enough strength 'built in' to the wing joiner tube and two dowels and retaining bolts, so no additional strengthening is required. For my own Calmato Sport, I've built it exactly as per the instructions, so assembled it 'dry' and made the two halves secure with insulting tape. To be honest, I toyed with the idea of leaving the tape off to allow the two wing halves to fit in my car easier, but bearing in mind that the fuselage is nearly as long as the wingspan, and itself won't fit in without moving the passenger seat forwards, decided against it. Kim. p.s. Has yours really got fibreglass tape over the join? If so, is it adhering to the base wood, or laid on top of the covering?................ just curious Kim eta pps I love that the manual earnestly tells you that if the wing comes off in flight, you MAY lose control of your 'plane.

Now you've done it!!!! Wrt your original post, I'd ask whether the tx was sitting in full sunshine before the incident? I think I've had similar, in hot/sunny weather (by similar, I mean unexplained loss of control). In answer to your next question, either of the Spektrum, or if you're not afraid of a bit of a learning curve, one of the open source radios, plus a 4 in 1 module to emulate your existing Spektrum, + any others you may have or want to try. I went Radiomaster TX16S Mk11 with the built in 4 in 1 module and don’t regret it (yet, anyway) Kim

I honestly think that you need to scroll back to page 1 of this thread, where the o/p gives specific information on how he overcame similar issues with his Ruckus. His findings back up my and others views that a more rearward c of g will improve or eradicate your problem. You may end up with the elevator at what looks like a funny angle, but as long as it flies right, who cares? You can't see it once it's in the air. Worth trying?? Kim

Sounds like a job for B&Q. Match by eye using the Valspar colour chips or I think they have a colour matching service. Then get a tester pot mixed, usually enough for our purposes. Or, if you want an enamel or 2K paint, most auto paint suppliers have a match / mix service on site. Kim

With the greatest respect, you don't know whether it's nose heavy or not, until you get it trimmed correctly and check the c of g in flight, where it matters. The numbers are just that, numbers on a page and are a recommended starting point, not cast in stone. But the plane is yours, you can do with it what you will, and I hope you get it sorted. Kim
-
Not in my experience - I put it down to having to trim additional up elevator to counteract the nose heaviness, then when you open the throttle / increase speed the up trim becomes excessive and up she goes. I've had similar on a foamy Riot, which I've got balanced either at or behind the recommended c of g, and a Wot4 woody ARTF, which if memory serves, was a good 15mm behind the recommended rear limit KIm eta I should add, that the method I use to set c of g is to trim for level flight at half throttle, then roll inverted to see what happens. When it flies inverted either hands off, or with a whisker of down stick, jobs a good'un
-
In my experience, the Max Thrust planes, both Riot and Ruckus fly nicest with the c of g at or near the back of the suggested range. Pitching up with increasing throttle is normally indicative of a forward c of g, I thought. Kim Eta To get it close to a 'Wot' of any flavour, you'll need to increase the throws above the 'book ' settings, particularly the ailerons.

Spektrum 2.4 4.8v RX battery?
Kim Taylor replied to martin collins 1's topic in All Things Model Flying
I've now noticed an unfortunate typo in my above post, which I can't edit - maybe a mod can correct it for me😚 Kim
