Align T-rex 700 crash repair / maintenance error!!

A clip about how i crashed my 700L, could have been a lot worse and annoyingly easily avoided with more frequent pre flight checks!!
please like and sub and folow my RC journey.

Ouch ! 15+ years ago went to show a friend my raptor 60 with ppm radio had changed the crystal and forgot to put the one in the radio lol old school stuff and fired it up watched it fly sideways into a tree 😂 good times never did that again now im very pleased to fly with nx6 👍

When I first started in helis about ten years ago, I had 4 times that amount of experience in fixed wing. Thread locker wasn’t used all that much in my airplanes. What I discovered was my ignorance of where it should be used. One place was the servo mounts, the other was the control horn screw. I was luckier than you because I found it as I spooled up and it rolled hard right immediately when I increased collective. Sorry for your crash, helicopters seem to resemble a dying chicken beating itself into the ground. Great tip on the feathering shaft.

[@danieljohnston1111]

Thanks for the comment mate, yes at least we've learnt now maby the hard way but it certainly won't happen again 🤞🤞

[@NJ-Tech]

Sorry for the crash, straight back on the horse is the way. A little tip i found years back with rolling the feathering shaft, do it on a mirror becuase it will double the error, so to speak. Ie, youll see twice the gap making it more obvious to spot if there is a bend, which you might not spot otherwise. Good video matey.

[@danieljohnston1111]

That's a treat tip mate thankyou very much for the comment, hopfully I won't need to test that method any time soon 😂😂

Really interesting video but shame about the circumstances. Nice to see another UK channel. Subscribed.

[@danieljohnston1111]

Thankyou so much for subscribing, and I'm glad you found it interesting 👌, I'm so glad it's all back to together now, happy flying mate 🧡

[@konekilr462]

Great video! Bookmarked for my 700L build w/speedfuse. I have the blue one though. 😉 Subbed!

[@danieljohnston1111]

Brilliant, thanks for the sub mate I hope to make more content soon. Been incredibly busy with work lately. Really need to get some more uploads going 😊

[@alvinrcflyer9747]

Great video Dan , very interesting, absolutely gutted it happened in the first place, but great to see you’ve got the skills and experience to repair it, and thanks for taking us with you through the rebuild, another excellent video, take care Dan 👍

[@danieljohnston1111]

Thanks for the love mate, I'm glad she's back together and ready for service again.. Look forward to flying with you very soon mate 👌

[@Raptor50aus]

The joys of RC helis. It will happen again.

[@Dragonewiz]

Very nice...👍🏼💯...i had a 700 just like that...awesome heli...crashed it and sold it😢 Happy flying...👍🏼✌🏼🙏🏼

[@danieljohnston1111]

Cheers dude yes it's normally the only outcome isn't it 😅.. In this case I flew it after the rebuild for a few months and sold it as I have the 760x.. Incredible machine I miss it

[@rachaelplant2504]

Really good and informative video ! You are now known as Dan the no pre flight man ! XXXXXX sorry for your bad luck ! see you soon ;-)

[@danieljohnston1111]

Haha thanks Rach.. I know I could kick myself, certainly a mistake I won't make again.. Hopefully see you soon 🚁🛫

[@HeliShed]

Oh my days - i feel the pain DJ - but ya know what, crashing is part and parcel of the hobby and i too, have been where you are and, continue actually - I've just crashed one of them - vid soon. Thanks for the vid and effort. Well done on a great repair and maiden mate.

[@danieljohnston1111]

Mate not the first and definitely won't be the last 😅 look forward to seeing your video mate ❤️

[@jeffs7915]

Bought it from someone who looked liked they knew what they were doing, Famous last words. Yeah it only looked from a far. The bolt and bolt head is undergoing tensions forces, tensile strength is how much force it can withstand. Your thrust bearings that trap the bolt head and main blade grips are experiencing compressions forces.

[@jigglypuff4227]

Awesome editing on the video

[@danieljohnston1111]

Ahh thanks very much mate, I'm only starting out with the whole KZbin thing, really appreciate your comment 😊

[@johnblythe6453]

Also very high quality video what camera did you use ?

[@danieljohnston1111]

Thanks John, I use the Gopro hero 7 black and my Samsung S23 ultra.. Between them there is some good quality 👌

[@djisydneyaustralia]

Thrust force, it's being thrust outwards by centrifugal momentum.

[@rcsendandblast1579]

Great job dude. Could you ask /tell all you know in the hobby Canada's hobby fun is dying at we need it back like you guys have kept the hobbies going strong. I know I'm asking something out of the ordinary and maybe I worded this wrong. We need help nitro is dying almost completely and even my hobby shop who is but OF I shop he said to me I need to give him a deposit for One losi diff gear. Apologies for the rant we need help or the hobby here will drastically change as it already has. One good example is ntitro is now illegal to use in almost every public place I guess the best thing to do is raise awareness and hopefully we'll get this help from everyone that we need so much.

[@flycatchful]

I had an Align 600N explode on spool-up. Never did discover what caused it.

[@danieljohnston1111]

Ouuuch... Even worse when you never find out

[@gauix7]

The bigger the helicopter, the more expensive the parts are. I also fell from a steam 700 class tarot helicopter, but the helicopter is all broken.

[@johnblythe6453]

Heli,s can be such time wasters + nothing to show but crashes !!!! there are 2 guys in our club that fly them + they are experts i can "no way" copy them so i bought a flywing gps 450 which i can fly around its good enough for me , i have 700 Align which i will convert to gps its massive + very powerful also i fly fixed wing so i like to maintain my flying skills with them .Heli,s are so time demanding try other flying as well for a change .

[@pwoolrich]

Nice video mate!

Cheers buddy much appreciated

Torsion

[@The_regular]

Could you show sometime what you need to run that receiver with the spirit FC? I was using a satellite but your setup would be perfect from my scale heli because it should allow me to run two extra servos

[@danieljohnston1111]

Yes no problem it's just a simple servo lead but at one end the signal wire is separate so 2 plugs at one end, then following instructions in the manual one end into their data port on the receiver and other ends onto the FBL

[@The_regular]

Ahh it looked like you had the s bud port. Puuhhed in but I see you have another satellite

[@francescolocorriere]

listen to me as well as putting the threadlocker in ALL the screws that go into the aluminum you have to put the threadlocker even in the screw that the servo lever. those servos align they tend to unscrew the bracket screw. Same thing for the tail servant. if you have plastic put a little of attack. all plugs put hot glue. there are Brands of threadlocker which they keep well today. but if you check again in a month or two It seems like disappearing. So if it happens you have to insert the threadlocker again. but change brand if it happens. remember the hot glue the vibrations disassemble everything. PS the thrust bearing you don't have to put the first screw and block it already. you must have the same distance when you see from the hole of the thrust bearing. this way a thrust bearing is pushed more and the other less. uses a one way bearing to disassemble a screw from the axle But when you have 0 degrees do you also have the levers of the head aligned? they seem slightly lowered

[@alwaysflying6540]

It's hard to believe you didn't feel that in the air. The helicopter would have felt really sloppy and disconnected, and terrible blade tracking

[@danieljohnston1111]

Honestly absolutely no signs, I was flying fast and lopping and rolling the first sign I had of something a miss and a second later lost all control, also that's incorrect regarding the blade tracking, blade tracking was unaffected (till impact) blades are tracked in reference to the swash plate, it was one of the 120° Cyclic control points that I lost (being a servo) so no control over Cyclic or collective.. A mistake I won't make again 😉

[@alwaysflying6540]

@danieljohnston1111 I can believe you about the blade tracking. After I gave it more thought, I realized that the servo could have stayed in place until the last few threads. I was doing a test flight on a guys helicopter once. It was a trex. I never checked to see if he loctited the servos arm bolts. All was good, put the machine into idle up 2, and boom, the heli was all over the place and smash. One second to the next total Kaos. Checked it over as it lay on the ground, and the arm was still connected to the linkage and no longer connected to the servo. Blade tracking fine as well.

[@danieljohnston1111]

@@alwaysflying6540 It's painful isn't it, no second chances with helicopters m but that's what I like you have to earn the knowledge and proficiency to fly them unfortunately we're a small bunch now,

[@alwaysflying6540]

@danieljohnston1111 I'm one of the few 3d helicopter pilots in our club now. I fly fixed wing as well. Most guys fly edf's now. People give up on helicopters to easy these days

[@jigglypuff4227]

Do you normally use loctite to mount these servos or not?

[@danieljohnston1111]

Yes pretty much everything with a metric thread benefits from a dab of loctite, not too much is the key

No noo.. I'm totally at fault.. Its my responsibility to ensure the model is safe and secure prior to any flight, I just put this out there to encourage others not to make the same mistake I did regardless of the seller and their experience!!
