- My T-Rex Helicopter's 1 way, Autorotation bearing failed at the beginning of my flight. Here is how I easily fixed it with a test flight afterwards. This removal method and the pressing in of a bearing will work for many helicopters and gears. Thanks for watching.

Ahhh I miss this channel. its been 11 years. I started watching because of the tiny uss catapult:D
Welcome back.. That USS Catapult was a fun video to make. Thanks kindly!

I usually just buy the whole hub assembly in order to avoid pressing out the one way bearing. But good to know it's an easy job.
I just love how you still meddle with it all and ofcourse it works,my hero for ever,chiao Piet.
Haha jij hier?!
You are very kind Piet. Thanks very much!
Thanks for another video Dave. I look forward very much to watching later today. _John_
Thanks much. I appreciate that.
Hi Dave,
You made that repair look easy. You also do a nice job on the sticks. You and Ilea stay safe.
Thanks a lot Don. You stay well and safe too!
I learned how to fly helicopters on this channel a long time ago, thank mr nightflyyer
I appreciate that and really appreciate your long time subscription. Stay well and stay tuned. Thanks kindly.
Thankssss, worked perfect for me !!! Thanks Mr Nightflyer.
Your very welcome, Martin. Happy flying.
Dave congratulations on getting into the Hall of Fame. Nice bird. Myself I just replace the whole one way bearing assembly that has the bearing already installed.
That will work too, but I only had the bearing. Thanks much.
Thanks Dave
I never looked at a drill press as a bearing press . I love that idea duh
Glad you’re fixed up and flying again
More inspiration to get my but back out to fly
Thanks so kindly. Now get out and fly!
Nice landing!
You immediately reacted to sudden loss of power, that really takes next level of focus
Edit:grammar
Haha, yes, well I had no choice. Thanks so kindly!
pretty sure he flew choppers for the US.. hes trained under pressure.
A very wonderful job Dave and
Insightful the way you was to explain how to get all fixed up.
Glad you enjoyed it, and I appreciate your comments. Thank you very much.
Now that was close! Lucky you were close to the ground. I bought many gears and bearings for my 450 home builds. Great content 👍
Yes, I am glad it didn't happen up high or when I was inverted. Thanks much Don.
I like the detailed way you explain things👍
Loved the inverted flight!🚁
Thank you sir. I really appreciate that.
Well it definitely helped me! I’ve had to switch out many a damaged main gear on both my 450x and my 360 CFS and it can be a pain. Thanks for the tips, Dave! Semper Fi.
Glad to hear that Scott. Thanks and Semper Fi!
Great how to video, thanks Dave
Thanks kindly Johnboy!
Nice flying, Glad to find a good rc heli Channel
That is nice to hear. Thanks very kindly.
Hello Mr. Herbert .Enjoy all your video's . I have a question for you . I have a TREX 450 . When I give it trottle only the top or large gear turns . I can turn the bottom gear by hand and the top gear doesn't move .Doe's this mean my one way bearing is failing . Thank you so much . Bobby Miller
Well the top gear is connected to the Motor Pinion gear and spins with the motor. If you can turn the bottom gear only 1 way, then all is good. But if it turns both ways, the bearing is bad. Hope that helps. Thanks so kindly for watching. Happy flying.
@@NightFlyyer Thanks , The the bottom gear turns both ways . I have ordered a bearing . Thanks again . I will also watch your video on replacing the bearing I truly enjoy watching your videos . They have helped me so much . Thank you again , Bobby
Pretty god idea about using the drill press, ¿which gyro are you using?
I am using a Quark Spartan (MEMS) Gyro. Thanks very much.
Yep, it's good to know the number one aero-surgeon, that knows how to fix an autorotation bearing that's beginning to slip on a T-Rex..! 'Oorah'
Thanks a lot Bud. Semper Fi!
Awesome fix, FYI you should have applied a little bit of high temp bearing grease in the bearing prior to reassembly. I also clean and re grease mine every 4 or 5 months of flying depending on how hard you push them. Thanks for the Vid.
Yes, I would have put grease in it, but it came already loaded with grease, so didn't need too. Thanks for the tips and comments, Don.
Thanks New video! 😬✌
Thank you much Andy!
Hi,
Is that the heli that you used something like 13 years ago, pond fishing? Or maybe it's just the similarity of the foam pontoons that I am recognizing.....
Anywho, nice work......So glad that you are still making your vids, Dave. I cannot believe how quickly these past 13,14 years have slipped by. You were one of my 1st subs back in the wild west days of youtube.
No. I think that heli fishing video was done with a Blade 400. I put Pontoons on all my helis, as it makes it easier to see and puts it up a bit higher in the grass. That one was destroyed in the fire on 911, 2016 with all my models, cars, and home. Thanks kindly for being a long time subscriber. Stay well.
I wonder if you could give me some guidance, I'm learning to fly rc helicopters and I bought a vintage hirobo falcon as a project while I learn. (I'm a mechanical engineering apprentice and live for this stuff.)
My question is this: what is the best way to replace blades? I'd replace them with new fibreglass ones but all seem to have only one hole for fixing to allow them to pivot. I considered drilling a second hole but I don't want to waste £40 by wrecking them. It has a pair of serviceable blades, though they look a bit tatty. Any advice would be greatly appreciated.
Congratulations on taking the time to learn helis. I have many instructional videos on the subject and it helps to have a good simulator. I use Aerofly Ultimate, as it feels the most like my real model helis. Many helis only use one hole these days and they swing and wobble when not in line. Real helis use the locked blades when in flight, so there is no problems. You can use 1 hole, so try that first. Make sure the blades are not too long, as they can hit the tail rotor and make sure they are not too loose, as jockeying the throttle can cause them to get out of line and hit the tail boom. I know this all from over 50 years of flying them and had all kinds failures that is part of my learning curve. See my video on wobbling helicopters. Here is a link and good luck. th-cam.com/video/KLLfnJajixU/w-d-xo.html
@@NightFlyyer thanks very much, I will definately look at getting a decent sim as I hadn't really thought about that. For now the original blades are probably ok, but just in case I'm glad there is the possibility of replacing them if needed.
Good vid Dave. Could you see how the original bearing failed?
I could not see exactly what happened inside, but it sure did slip. Thanks kindly, Christopher.
Enjoyed the video Dave!
Glad to hear that. Thanks kindly Doug!
Such useful/helpful info, Dave! Thank you!
Got a problem with my Trex 450SE: keeps browning-out in flight, SEVERAL times in one flight! Had to land immediately, and had to stop flying it. ESC seems the most likely, but I've had two different ones in it and it still browns out. WHAT the heck could be causing a power loss mid-flight? Don't think its the Rx cuz I got a new one from Spektrum and they said nothing was wrong with the one I sent back. Could a bad motor cause a short/power loss in the Rx? Servos? Gyro? I bought it used from a guy (many years ago) and it's ALWAYS suffered from brown-outs. He says it never did it when he was flying it. Now, he was flying a Futaba Rx and I installed a Spektrum Rx. Could THAT have something to do with it??? It's a beautiful machine, my pride and joy, and I can't fly it cuz I have NO IDEA how to fix it. I bought a new motor for it but I don't see how the motor could cause a power loss in the Rx??? I don't have any spare servos, gyros or Rx's so I can't do any troubleshooting, really. Have YOU ever experienced brown-outs?
Hi. Well I have had only a couple brown outs and loss of binds, but it was due to the BEC, in the ESC, I found. You might try to put a 4 cell NiMh battery in it to run the RX and Servos and skip the BEC. The battery is a constant voltage and you might be able to determine it that way. I don't recommend using different brands of TX's and receivers, as Protocols may look the same, but..... Good luck and happy flying.
What gyro are you using on this Trex 500 / Dx6 ? Could you please advise...
The Gyro is a Quark Spartan. The TX is a DX8, Gen 2.
Very nice 👍😁
Thanks kindly, Dave!
May I suggest putting you bearings in the freezer for a few hours it make pressing it in much easier.
Good job thanks
Thank you David!
Cool 👍👍👍🚁🚁
Thanks very much, David!
Nice nice nice
Thanks much, Jon!
the same method also applies to the 450..just smaller..
So true and as I mentioned in the video notes. Thanks much!
help I need spare parts for me RC exceede Falcon 40 I occupy the main propellers and the tail rotor
Many blades will fit. Mine was destroyed in the fire, so I cannot look at it to come up with a replacement. Sorry.
I'm probably gonna need to do that at some point with the one-way bearing in my T-Rex 500 ESP 3G (of which, is nearly ten years old). Good to know, for future reference.
=^/.^=
PS: My birdie has the exact same gear train.
Yes, it might not be a good idea to replace it before it happens, being that old. Thanks much.
Молодец!👍
Are you on discord?
Not sure what you mean by that.
@@NightFlyyer discord is an app you like put on your pc or phone and you can chat with like minded people.
@@madbren Got you. Well I don't have that. Sorry. I have enough trouble keeping up with the comments here on YT, an have been answering comments for the last 3 hours on all my videos. LOL.
@@NightFlyyer no problem I totally understand its just that iam in a community on discord and a guy like you with your as I call it encyclopedia knowledge of rc would be invaluable in the rc community. Stay safe I really enjoy your vids and learning from the veteran's like yourself in the rc world. Your a walking encyclopedia mate.
@@NightFlyyer well if you ever changed your mind it rcvideoreviews on discord this guy goes under the same name on TH-cam and we have wings, and radiomaster and bitgo hobby in the group aswell as pilots from allover the world.
