I believe sbus is compatible. I run sbus with an MSH Brain flight controller and they talk flawlessly. I've also used Arduino sbus library to read frsky sbus data.

John_M_

OK, thank you... arduino sbus library compatible with the seeed xiao?

Glowgeek

Hey Bert, have you seen one of these?

I believe it is.

John_M_

OK thanks Raleighi'... looking at the copyrights for the library now... just making sure what I can, and can not do in regards to using it in this project.

John_M_

I was browsing frsky's website looking at the various telemetry sensors / ula scripts, and happened across this particular gas sensor suite for remote monitoring in real time internal combustion engines... monitors engine rpm, temp, fuel flow velocity / fuel consumption / gas quantity... as well as control ign manually, on/off kill switch... The fuel flow sensor has a ± 2% accuracy, temp sensors ±1%... Surprised Bert hasn't seen this, not sure if it's accurate enough, but thought it was pretty neat none the less.

That fuel flow sensor doesn't have accurate readings at the flow rates our engines use. It's more suitable to fuel flow rates of turbine engines.

John_M_

It the pdf manual, claims its intended for use in monitoring gasoline internal combustion engines, no mention of turbines, but the ± 2% accuracy at those flow rates, I would tend to agree... they do say those values are customizable via the ula scripts, and updated firmware... it's suppost to show remaining fuel quanity based on the tank volume size listed in the ula script... its a neat concept, but needs better accuracy, and improved sensitivity... it's been out since 2018.

Crickets chirping around here, hope everyone is doing ok?

My Feedback: (1)

Im OK... Hope all the others are..

Just been very busy with work. Did get out for the first "official" fly of the year last weekend - we had an "early-ish" spring but Mother Nature returned us to cold and wet for a few extra weeks - looks like its going to get nice now..

Here OK as well...
Had an episode of BPPD about two months ago, rendering me unfit for work for about a month and another month of carefully returning to duty in small increments.
BPPD is a condition in which tiny cristals of calcium (or so they say, not sure if the scientists agree on it) occur in the semicircular canals of the balancing organ in your ear.

Man, a three day long rollercoaster ride, wilder than any REAL rollercoaster out there...

But since last week reported "recovered" to my employer, and back to work again.

Have been messing about with engines, flying, etc but all on a fairly low level the last 5 or 6 months due to other private circumstances. Slowly getting back to normal.

G'Day G'Day...Does anyone know what battery fits the MIP TG3 nitro engine temp sensor?
Mine went flat, I pulled it out so I could take it to the battery store for a replacement, and...ya know, life happened and it's lost.
I really want to get it going, again, I've got a very modded TLR TEN SCT Nitro, man that truck is a blast.

There usually is a battery type cast in in the battery lid or the battery recess.

Assuming it is a button cell of sorts, just bring the sensor, and check which one physically fits. Since virtually all of them are the same chemistry and therefore the same voltage, 99% chance it will work.
Just pay attention to polarity.

Hello I am trying to understand over time Brutus remains a science.. I would need your skills if you could contact me thank you for discussing a Glow engine in gasoline thank you

1967brutus

Feel free to ask your questions, and I or one of the others will try to answer them to the best of our ability. But we first need to know what exactly it is you want to know, because the field of glow engine conversion to gasoline, can be quite extensive.

From what I understand, you have a Saito, and that is a good thing, Saito engines are relatively easy to convert, and very suitable for conversion.

Johnfrench13

Hello I would like to convert to gasoline gasoline as quickly as possible can you tell me how much' for me I am not equipped I would also like the Stihl valve which you can obtain in fact thank you

1967brutus

At the moment I have the electronics in stock (€25), and I have the housings for the solenoid (€15).
I need to find a new source for the solenoids, because my previous supplier closed his business. Because of that, I cannot give a price for that yet, and also, I cannot give a delivery date.
I expect the solenoid to be €25~30, but for now unknown.

Please be patient, I recently had a change of job, and this negatively affects my free time for assembling these kits.

You will need to source your own ignition (RcExl) and sparkplug.

You will find your friend Guillaume here under the username Billy603, he will be able to help you in your own language which makes things a lot easier for the technical details.

You are aware that you will need a radio with good programming options (OpenTX or comparable)?

You are aware that you will also need to re-do the fuel system in the plane (use different fuel tubing, and the fuel tank needs to be made suitable for gasoline)?

Mechanically, the modification is relatively simple, but the devil is in the details, Guillaume can tell you all about that.
The hard part is to find the correct settings for your radio. Guillaume hould be able to help you with that also.

Again, please be patience, I need to find a good supplier that can deliver solenoids for a decent price.

Johnfrench13

• Hello in radio I have a flysky fs st8.tx.ok thank you

[QUOTE=1967brutus;12804191]Pour le moment, j'ai l'électronique en stock (25 €), et j'ai les boîtiers pour le solénoïde (15 €).
Je dois trouver une nouvelle source pour les solénoïdes, car mon fournisseur précédent a fermé son entreprise. Pour cette raison, je ne peux pas encore donner de prix pour cela, et je ne peux pas non plus donner de date de livraison.
Je m'attends à ce que le solénoïde coûte 25 à 30 €, mais pour l'instant, je ne le sais pas.

Soyez patient, j'ai récemment changé de travail, et cela affecte négativement mon temps libre pour assembler ces kits.

Vous devrez vous procurer votre propre allumage (RcExl) et votre bougie.

Vous trouverez votre ami Guillaume ici sous le nom d'utilisateur Billy603, il pourra vous aider dans votre propre langue, ce qui facilite grandement les choses pour les détails techniques.

Vous savez que vous aurez besoin d'une radio avec de bonnes options de programmation (OpenTX ou comparable) ?

Vous savez que vous devrez également refaire le système de carburant de l'avion (utiliser des tuyaux de carburant différents et rendre le réservoir de carburant adapté à l'essence) ?

Mécaniquement, la modification est relativement simple, mais le diable est dans les détails, Guillaume peut vous en dire plus.
Le plus dur est de trouver les bons réglages pour votre radio. Guillaume devrait pouvoir vous aider là-dessus également.

Encore une fois, so Hello ok let's PM yez patient, je dois trouver un bon fournisseur qui puisse livrer des solénoïdes à un prix décent.[/QUOTE Hello I am open pm thank you
] Bonjour Ok on passe en mp .. aucun problème merci

1967brutus

AFAIK, that is OpenTX, and that should be more or less perfect for this application.

Meanwhile....

Some of you have probably noticed that I have been less active in the last 10 months or so.
I apologize for that, but life's snags seem to come in tidal waves, And in my case it has been high tide for the past 10 months...
Neither going to bore nor bother you guys with that, it is what it is and we're on the way back up. Spent most of that time tinkering with RC boats (gasoline and steam, it HAS to "burn something" after all). Carefully started flying again since about April, gradually increasing in frequency.

There have not been any new developments from my side, because basically, the solenoid solution has shown to bee matured and I've done it all as far as combustion engines go. 2-stroke, 4-stroke, multicylinder, radial, even a Wankel, all have been successfully converted, run and flown. Durability of the solenoid set-up has been proven, the oldest systems (pre-atmospheric compensation) have been in use since April 2019 and are still as functional and precise as they were the day I installed them, the first experimental compensated versions (with "open loop" compensation i.o.w. pressure/temp sensor returning data via telemetry, compensation executed via LUA script) are still functional in unchanged form since maybe 2020/21, the later versions with internal compensation also still work flawless.

In fact (and this was the inspiration for this post) the tiniest engine I run at the moment, the .30 ASP fourstroke, with the tiniest of fuel passages, due to the aformentioned "high tide" had been left unused since August last year. No lay-up procedure, no storage precautions, nothing... The pause in activity was not planned or intended, so I took it off the shelf last Saturday, the way I left it in August last year.
The fuel passages in the carb were plugged with oil from the fuel, and it took some convincing to get the fuel flowing again. Absolutely unproblematic, all I did was open the throttle fully, put a finger on the intake and crank the engine with an electric starter. Took maybe all of 2 or 3 minutes before the first popping noises from the muffler, and within a minute it was running as if it had been used the day before, on the same can of fuel that I mixed somewhere in the spring of 2023.
SInce I use E10 (regular 95RON unleaded, containing 10% Ethanol) which in general is said to go stale within a few months, apparently, these claims of going stale are highly overrated, and the engines are pretty insensitive to the fuel quality.
I used the engine all afternoon yesterday for novice flight instruction and the engine functioned flawless. Did not even need to touch the needles nor the fuel curves. Did not need the electric starter, and handstarting was within 3 flips at most.

The tow-plane had to earn its keep Saturday, with a pretty draggy vintage style glider in tow.

I would like to know: How do you guys fare? Those of you that have one or more converted engines, what are your field-experiences?

I'm just getting back to flying after 18 months. I had lasic 18 months ago and have struggled with seeing the models. After 18 months of recovery my vision is much better but I'm still struggling a bit with seeing the models. I've recently been flying my helicopter and it's been fun although I'm a bit rusty. I'm experimenting with different color sunglasses to see if that helps and it has. Hopefully I'll be back to airplanes soon.

I did order my new car last weekend so there's that

1967brutus

Oh, Dang.... Lasic is supposed to improve your sight, no? Really hope the sight returns.

Raleighcopter

It does and it did. It takes a while to heal from the procedure and your vision will vary from crappy to excellent during that time. I also did monovision (one near eye, one far eye) which also takes time to adjust to. My vision is pretty good at this point it's just not as clear as a distance as I'd like.

1967brutus

That is good to hear. Here's hopin vision will return to normal ASAP...
