Echt zonde, maar je bent er niet alleen in. Is mij ook overkomen. Na 8 vluchten, moer los van de prop en de MUS was cone. Maar weer wat bouwen he.. Zo is het met deze hobby. 😉
sad.i am having real struggles with my first rc plane design,spent 5 months and more than 2 still to go.and this beast goes down after years of the testing.sorry for your crash.
A Deja vu moment of my Christen Eagle 50cc coming out of a split S still behind a stand of trees exactly like those while trying to set up for a long low inverted pass!! Not only the impact noise but the kaleidoscope of colors emerging out of the trees too. 30 years later, my then ten year old nephew still has the canopy with pilot as a keepsake.
I had a small ME-262, one speed control and it's EDF unit would go into low voltage cutoff while the other speed control and EDF unit stayed at full power. The solution was to cut throttle immediately and glide in dead stick or never fly long enough to risk LVC and assymetrical thrust.
If you're aware that you lost a motor you can try that. But we weren't aware (happened quite far from us). And gliding in this Mosquito is just impossible. As soon as we lost the motor it was game over. I tried and fought until it crashed but to no avail
I think a self locking nut is better (we call it a nyloc here). Anyway if this saves one model it's worthwhile. What kind of brand is your partenavia? I have one not yet finished from modelstudio.cz
I have had a twin lose a motor too. If you know it, you immediately kill all power and try a dead stick landing. If you don’t know it, they always spin and crash…
You said it correctly, "if you know it". We didn't :-( I have saved multis before in such an occasion, but we were too far out anyway to glide it in. This Mosquito has a glide path of a brick...
Dammit. Sometimes our hobby hurts. I finished my second scratch built plane from old school model works. Took me a month to cover. Flew it for 2 weekends no problem. 3rd weekend the elevator fell off because i didnt glue it at all by the looks of it. Sorry that happened
I lost a scratched built Hurricane back in the summer from a failed aileron servo. From straight and level ot rolled over and went straight in! Makes you feel a bit sick 🤢
Sorry for your loss, you had the hammer down for virtually the whole flight…. How close is that wind turbine? It’s probably just distance perception but how many models has it claimed I wonder…🤔
When I saw you fly in front of the windmill, I thought that was going to be the crash. It looked pretty close to it. At first, I was expecting it to pass behind the blades, not in front.
Bij een CW draaiende prop kan de propmoer gewoon losdraaien. Hier had er een locking moer op moeten zitten, of twee moeren. Vliegen op 1 motor? Tegen dat je het beseft wat er gebeurd is het rijkelijk te laat. BIj 1 motor uit is eigenlijk het beste devies: de andere ook direct afzetten en proberen binnen te glijden. Dat heb ik vroeger ook 1x gehad met een ander toestel, maar is toen ook mislukt. Veel hangt ook af van de grootte van het kielvlak, de hoogte van de romp. De hoeveelheid richtingsstabiliteit. Als je het al weet dat er 1 motor uit is kan je nog proberen... Maar dit is een zware jongen, geen lichte foamy. We waren eigenlijk kansloos...
Die is helemaal vernield. Helft van de romp is confetti, vleugels opengespleten, ... Het was ook niet mijn model maar van een vriend maar we hebben er samen veel over geredeneerd, gediscussieerd etc. Ik heb er altijd mee gevlogen als testpiloot en we waren net begonnen om hem te laten vliegen door m'n clubvriend. Jammer...
I was expecting you to say the right engine ran out of neurons due to full throttle being used for most of the flight (5 minutes or so). We usually set a concervative timer of say 3 minutes and land to see the % used and inch up the time accordingly. Lately of course we all have flight pack telemetry so we know when we reach storage voltage it is time to land. Some of us use both the timer and telemetry to ensure we get to take the plane home in one piece.
Engine? Neurons? What are you talking about? :-D Of course we measured and calculated the flight time, of course we measured how much mAh went into the batteries again after previous flights. Nice suggestion, but there was plenty of flight time ahead.
Bedankt voor je reactie. Nee, stroommetingen vooraf sluiten dit uit, en bij de eerdere vluchten bleek alles zeer doenbaar qua warmte. Motoren zijn niet verbrand. Maar is zeker een factor om rekening mee te houden bij electroaandrijving.
We can only guess that you have taken the short cut, simply watched and couldn't be bothered to read the description and other comments before commenting yourself.
No, no stall. At least not at the start of the mishap. If you look closely you'll see that in the final spin it suddenly goes the other way. That's me trying and fighting everything I have. The first spiral is losing the motor, the opposite spiral is the stall during my fighting. You actually hear a screetching noise, be aware that the sound takes some time before it reaches us (it was quite far at that moment). Broken parts we found afterwards confirmed this e.g. we found the 3D printed spinner were the central hole was melted out. The nut went loose, the spinner and propellor started freewheeling, created a lot of friction against the spinner (and eventually lost the prop). That's the screech.
@@johnnichol9412 Some more explanation in my previous comment. It stalled eventually but first we got a spin from losing a motor, and the stall goes in the other way around. My initial thoughts were immediately that this could not be a stall because the model turned right just before the spin. And that turn was not steered. But in the end, it has all the same result....
Try again. Tell me, where in the video can you conclude that it was not a stall, but a motor loss? Instantly? You have no idea. Luckily you have plenty of videos on your channel where you demonstrate your one motor/engine skill.... The first thing you think is: "Stall!" I have 8 years experience with twins and had my one motor events before. Even had a rebuilded trainer equiped with two motors to have this kind of fun on purpose. To learn. My H9 Twin otter lost one motor too (loose magnets) and it just flew 'not so comfortable'. The Twin otter has a huge vertical stabilizer too, the Mossie doesn't. Two things didn't help: we were quite far away. It was the plan that the owner (who flew when the mishap started, see the unexpected turn to the right right before the spin entry) would have brought it into the downwind leg, I would have taken over for the landing. So I took over instantly after the mishap started, so we lost there a bit of time. The event started when he was setting up for the downwind leg. If the mishap would have happened above the field, maybe, just maybe we would have been aware that we lost actually a motor. Now we didn't know that until half an hour after the crash. So in the opinion that we faced a stall I took the controls over, cut briefly the power, pushed her down, applied power again, countersteered. But there was not enough time, height, possibilities to recover it. I tried even when it was behind the trees. And actually the trees were in the way too If I had known instantly that we lost a motor I would have killed the other one too instantly and leave it like that.
Thanks for the reaction! I still believe the counter rotating propellors really helped. The Mosquito doesn't have big directional stability (vertical tail is not that big, fuselage not that heigh) so if you can rule out some troubles by using counter rotating propellors? Why wouldn't you. But please, lock the propnut of the CW very decent (CCW too, but that one is self tightening). On the other hand, if your Mosquito flies well I wouldn't change it. It worked out for us though
Wow, that was quite an impact.
You must be gutted
It was quite the impact yes... Gutted too, since the perfect setup was found and it finally flew fine.
Sorry to see such a sad end to a beautiful Mosquito after all your hard work.
Part of the hobby unfortunately....
My seagull mosquito had a similar fate
Ooh, that is bad news.... Yours sounded excellent with the Four strokes.... Yes it is a difficult bird 😕

It is sometimes a difficult hobby, but the rewards of some good flights are so great. Keep trying!
Tragic but after the effort you must have put in to this superb model we'll see you again.

@@driesneyrinck Yup, keep a close eye on battery pack health and land early with a twin setup.
Sorry about your loss. My Partenavia twin also has contra rotating props. Learning from your crash I will use threadlock on the reverse prop nut.
I think a self locking nut is better (we call it a nyloc here).
Anyway if this saves one model it's worthwhile.

That didn't sound like a plane crash either. It sounded like a gun shot and it was perfectly in sync with the flash.
Enig idee hoe dit kon gebeuren? Vliegen met één motor zou nog moeten kunnen voor het landen.
