Good stuff! I'm surprised how well it flew on one motor, considering there's no rudder. lol You motivated me to inspect mine, I found a crack in the left motor mount. Time to replace them I guess!
Nice recovery on getting it back Giz . Having another death at sea would have been awful lol . I think we take for granted the small nicks in props is ok I myself have done it on numerous occasions .I am glad you got it sorted take care
Yeah I was lucky. Would have been a kicker if it had gone down in the river lol. Very impressed that the T1 can fly fairly well on just the 1 motor though
Same exact motor that came loose on mine too. In my case, it was the PNP version before the new motor pods and gasket setup with 4 screws instead of just the two. I found the screws rolling around inside the pod. And my setup was stock motors. It's good to see it can actually fly with one motor out! My motor ejected itself during auto launch and the plane crashed right away.
Seems it's a very common problem, had numerous people comment saying their motors also fell off. Wonder if the problem was more common on the older versions? Mine was a V1 (from the original pre-sale) so didn't have any upgrades at all. Sounds like yours was a earlier version too? Hopefully the crash didn't do too much damage?
@@gizfpv I was extremely lucky. The auto launch did not get far or very high at all, so the plane more or less had a gentle crash and fall to the ground on its belly. The screws did not touch the ESC so they survived. I contacted heewing about this and they directed me to their new v2 motor pods with 4x screws and the gasket backer, and they gave me a 50% discount to pick them up. This is not an issue I’ve seen mentioned in any review, so I figured I was just unlucky. I am also new to fixed wing, the heewing was my first PNP plane and I bought it from banggood in September of 2022. Apparently I’m not alone, based on all of your comments! Maybe thinking of maybe sharing my story now as well. My friend ordered one of these from RDQ as well and he ended up with the V1 motor pods as well. I suspect there’s a lot of them out there. He immediately replaced it after knowing what happened to mine. Heewing also acknowledges in their literature on the V2 pods “a second set of screw holes was added to strengthen the installation stability.” So I take that as them knowing this is a problem. I was definitely perplexed to find that the motors were only held in by two screws against plastic anyway. 😕
@@JohnCuppi I guess none of the reviewer's mentioned this problem because it took a while to happen. I was one of the first people to get the T1 when it came out, and yet it's taken close to 14 months for the problem to happen to me. Kudos to HeeWing for acknowledging the problem and finding a solution though. And for also sorting you out at a discount, that's decent of them. I've just today ordered a brand new T1 PNP. Mines has had a lot of use of the past year or so and is looking a bit tired. Figure it's time for a new airframe, that'll hopefully come with the upgrades as standard 🤞🙂
those stock propellers aren't the best balanced props. I replaced mine with some hq t4025 and I could notice vibrations are reduced. There should also be a glassfiber (or some other hard material) plate behind the motor mount so the screws can't rip through the plastic mount.
Those screws shorting out your esc, saved your plane. If the motor had carried on powered up, the thrust from the motor hanging out would surely cause unrecoverable loss of control .
I actually looked at this (should have mentioned it in the video) and no, the gyro data doesn't seem to show anything unusual. The data looks much the same both before and after the motor fell off the nacelle
Hi Giz , thankfully the screws killed the Esc . Imagine the motor kept running while hanging like that . The recovery would’ve been even more difficult than it already was . Well done though 👍🏻
Nice to meet you. Bro. Building and flying drones is a very enjoyable thing for us. Sometimes there may be falls, and you may acquire another skill that you didn't use. I think it's a very high-end hobby and a fun hobby. Alarm set complete! Let's communicate. Bro
The same thing happened with my T1. Motor came off during flight 😮 It came down hard and cartwheeled a few times. Fair bit of damage and a lost gps module. Posted some photos on RCgroups. Lesson is check the mounts regularly…
Damm, sorry to hear that. Actually had a few people report to me since posting this video, that they had the same thing happen, and a lot of them ended up crashing. Seems I was very lucky to be able to fly the aircraft home
Respect; the outward spinning props made that save even harder. I have reversed mine to inward spin just for that reason. A single prop will induce both yaw and roll forces. If it spins inwards, those two forces will counteract each other. If it spins outwards, they will work in the same direction and add to each other. Mandatory knowledge for multi rated pilots, but sadly not for model aircraft manufacturers.
That is actually a really smart idea! I would have never have thought of changing the motor direction. I'm going to make this change to limit the chance of this problem happening again. Very clever bro 👍
@@gizfpv Makes differential thrust more manageable as well. You can google "critical engine" for all the full scale theory, but the principle is rather simple once you're aware of it. Happy flying!
Oh really? So it's not a problem unique to me then? That makes me feel a little better lol. Luckily on both occasions my motor was ok, but as I said in the video the ESC got killed. Luckily I had spares
Imagine if the screws didn’t short that Esc and the motor was whipping around while trying to fly back. I had a prop break on my nano talon after launch and it chopped up the tail of the plane but managed to glide it back home.
Yep was also thinking if it wasn't for the short taking out the ESC he most likely would have lost the plane. I honestly would have shrink-wrapped those ESCs at build but now it makes me wonder if it's a good idea anymore LOL. Would be cool if INAV could monitor motor voltage for say a out of balance prop/motor or tell if a motor stutters or gets jammed, it could potentially shut a motor down to save a plane, especially in a dual motor scenario.
Yeah for sure. In a weird way I guess I was quite lucky. If that motor had kept spinning it could have potentially torn chucks out of the wing or even severed the servo cable. Then I definitely wouldn't have got it back
What a lovely day for a flight! ;-D Maybe a lot of heat was being transferred to the screws from that motor, as a result of the dodgy prop and optimistic PIFF's, loosening the Threadlock. I'd say the shorted ESC also saved the foam, the wing, maybe the plane, from being eaten by said dodgy prop. Also, those houses are stunning, and some of them enormous! What happens if you go down on (what I assume to be) their land? Is all of that gorgeousness accessible?
I lost a 1.5m twin motor custom build for exactly this reason. Motors running warm, heat transferred through the screws and pulled the threads out of the plastic mount.
How much wobble do yall have in your motor mounts? I have the kit version and mounts tightened all the way but they just feel a bit loose. I may be switching to the 3d prints
Interestingly I did notice when doing the 2nd lot of repairs that the left motor mount (not the one that was effected in this flight) is a little wobbly. It's not significant, but there it can certainly wiggle a little. I don't think it's anything to be concerned about atm, but I'll keep an eye on it
I can't say I've noticed any difference between the V1 or the V2 antenna's to be honest. Maybe there's a difference if you fly behind objects quite a lot? But with the type of flying I do they seem to be much the same in terms of performance
Miracle it didn't go in TBH. If the dangling motor had kept running it would have. 1)..So, is that REAL blue Loctite? Or blue coloured Chinese stuff? 2)..Did you balance your props? 3)..Prop screws looked overtightened, which in turn split the hub...? 4)..Loctite blue low strength melts at fairly low temps. So did the motors get hot? 🤔😳😳🤔🤔🇬🇧
I have no idea if its real locktite or just blue paint 😂 It's whatever Heewing applied in the factory. I can't say I typically check the motor temperatures after flight, but as I typically fly at cruise throttle I'd be surprised if they were getting hot. I'll keep an eye on this in future though because as you said, excessive heat could melt the locktite. Admittedly I've never balanced the props, I just threw a brand new pair on the day I built this aircraft (March 2022) I never gave them a second thought. As for the prop screws being too tight, I don't think that's the case, but I can't say for sure. If they were too tight and that caused the crack, then the aircraft has probably been flying with a cracked prop for a very long time lol
@@gizfpv My suggestion?...Buy a small bottle of REAL Loctite and apply to ALL your bolts including the prop bolts. This way you can rest assured they won't loosen, and you won't be tempted to overtighten them....Buy a prop balancer, new props are often out, just sand the heavy blade...The axle type with brass cones are best, balance any prop regardless of prop shaft size....🤔😏😏🇬🇧

Remarkable the flight controller was able to provide enough stability to fly, especially since this plane doesn’t have a rudder. I assume it was INAV (or was it Arduplane?)
You were really lucky that the screws killed the esc because otherwise the motor and the prop would have gotten destroyed and the esc might have burned out and your wing might have gotten really shredded
Yeah.....because a motor had fallen off! 😂 Losing a motor caused asymmetric thrust which made the aircraft want to turn. To get it to fly a straight line I therefore had to add some roll input, which is why the aircraft was leaning left the whole time
@@gizfpv o lol. I was oblivious to the fact the motor already fell off when the flight footage started. Still not sure if I'd buy the T1 pro. Still have a wing to finish.

Probably a good thing that the ESC got shorted out by the screws or that motor would have been chewing your wing all the way back. Nice save!

It shouldn't be difficult to cut a small piece of thin plywood to fit in there... Good idea!
Wonder if wet/liquid thread locking compound for the motor screws got into the plastic motor mount.
My right motor fell off mine too, it always seems to be the right one on t1's. Extra Loctite has kept mine together.
Those screws shorting out your esc, saved your plane.
If the motor had carried on powered up, the thrust from the motor hanging out would surely cause unrecoverable loss of control .
Lucky that the motor lead disconnected so that you could fly under control with one motor! Good job saving it!
Yeah very lucky. If that motor had kept spinning I doubt the aircraft would have made it back
If you take off the filters in the gyroflow data, does the vibration show up there?
