Why You Should Never Trust Plastic Tail Blades!

- In this video we get the maiden flight in on a GAUI NX4, unfortunately it didn’t go to plan when the plastic tail blades exploded in flight. Plastic tail blades and nitro helis do not go together! Never trust them.

Get it going again we need more nx4 videos. I might get one
This one is back with the customer but! I plan on building one with a OS 55!
Sux mate.
I love my Gaui X4ii. I wanted the NX4.
Like gold to find now.
You can still buy the NX4 kit brand new from Anythingheli.com
Hmmmmm, I used to have plastic blades on my Synergy n5c and changed to switch tail blades. Glad I did after seeing this....😳
You did a good thing! Plastic is a big no no on nitro especially. I think the nitro degrades the plastic.
I just got the NX4 and she's a rocket ship !!! It's stretched to a 500 with an OS 55HZR talk about electric power on a nitro !! What an amazing heli
hi, i`m gonna build nx50 with 50 engine, did you try yours without stretching? i wanna keep the compact size
I plan on building a NX4 very soon with a OS55! I want that unstoppable nitro power!
@@westhobbiesrc8051 It's amazing the thing is still running rich and has gobs of power . I love the that helicopter, it's the best nitro That I have ever flown .
I have 3 of these and a T-10 motor just getting back into it can't wait to get new battery and governor bottom mount.
That was certainly an interesting end.
I have been very wary of plastic tail rotor blades _because_ of this reason.
IIRC, my RAW 420 has plastic tail rotor blades. Before I get her up & flying, I will immediately replace those blades with carbon fibre tail blades.
I plan on replacing her stock SAB blades with Rotor-Tech blades anyway (because they are far more efficient for my use case).
I definitely don’t trust plastic table blades on any helicopter really. YourRAW 420 has plastic tail blades? That’s not normal. They come with carbon fiber out of the kit. Did you change them out?
@@westhobbiesrc8051 It's been a while & it's likely my memory is failing me here.
'Cause I ended up having to leave both my RAW 420 & my Kraken 700 KSE behind, when I moved house about a month ago.
I only have my other three helicopters with me, right now. Two of which have plastic tail blades & they are both sub 300 class.
My only other 420 class helicopter that I have with me is my T-Rex 500 ESP 3G, & that has carbon fibre tail blades.
Dang it, I was really enjoying the nitro flight.
I plan on buying a NX4 and doing a OS 55 and posting more videos! I was enjoying flying it!
the hobby is expensive enough without having to put up with inferior components, your right though never trust plastic, stating the obvious but that sucks, all that work and effort getting the heli setup and built, to see it umble as a result of plastic failure sucks. never mind looks like a rebuild eat sleep repeat. you guys are great keep posting keep flying kep building.
It always sucks having a crash from a part failing. Unfortunately it can always happen no matter what you do or try to prevent. Rebuild and keep going! Lol thank you! I appreciate it.
a mates goblin fireball did it too
It is a very common issue with plastic tail blades.
The only problem I have ever had with plastic blades is when I hit a very small pebble. Other then that never had a problem with the kdbb blades coming apart. Have them on my 550 and 700. I don't do hard 3D though. The Align plastic orange ones that came on a used 500 though were absolutely junk.
I would never personally trust plastic tail blades on a 550 or 700. Plastic gets brittle after a while and they will come apart. Depending on how much dirt in the sun, humidity and temperature. Carbon blades have gotten so cheap now it’s not worth the crash to me anyways.
I had the same thing happen to me twice on an OMP M2 Evo, plastic tail blades ejected in flight. And that's just a 200 size! I never run plastic blades if I have the option! Sucks that happened, your maiden was going so well!
damn you freak me out now
It happend to me as well on my M2 Evo, I find if you tighten the tail blade too tight that's what causes it. Do you know if they make a carbon fiber tail blade for the M2 Evo?
I can’t tell you how many tail blades I’ve gone through on the M2! I now change it every 10 flights. That’s one thing I really like about the S2! Over 1000 flights and same tail blade!
Microheli makes a three bladed tail, but I’m pretty sure the S to tell blade fits on the Evo! And their plastic is incredible. Over 1000 flights on my S2 with the stock tail blade and the original one that came in the kit. I’ll check and see if it fits.
@@westhobbiesrc8051 the s2 is honestly the best value heli u could get. It just a superior model
Ordering CF tail blades as I type.
Good idea!
Dear god! great reactions on throttle hold but hells fire, shouldn't have happened - at least there isn't that much damage thankfully. I've never used plastic blades and now........................ never will - thank you for the vid!
Throttle hold is programmed like second nature lol if you can get on throttle hold before a crash it will lessen the amount of damage as there is no torque being put on the rotor. Carbon tail blades will last forever! Unless you crash lol
It happens to the best of us
Yes it does!
that's why i hate plastic blades. happened once on my 470lp
Luckily I never had a problem with the plastic tail blades on my 470LM but definitely getting carbon ones next!
Yep , plastics suck on big helis 😬
Yes they do!
Maybe I’ll buy another set of rails
They felt great! And you will have a spare! Lol
yo jeff. could you by any chance send the link for the head mount ?
I’ll see if I can find it. It is made by GoPro. I bought it for years or so ago.
Hi Jeff. I get that shipping costs vary on size and distance but what type of shipping costs are you seeing shipping 450 and 700 size helis say from your location to say Los Angeles? Figuring a 700 is like $100 via US mail?
If you go to USPS I'm betting you're going to be closer to $40. You just need to take the boom, blades and skids off to get them to fit in a smaller box
Hey Allan, yes around $100 to ship a 700. I’ve shipped them anywhere from $40-$120 depending on the box size, weight and location. LA is always more expensive. But, if the boom is pulled and in a smaller box it’s definitely cheaper.
Hi mate I have the same engine can u tell me what u set the low and high needed at from fully closed I can't get mine to run right thanks
Hello, so I believe low speed was around 1 /12 turns and high speed was around 2 1/4 turns from closed. That will get you a good starting point. But a rule of thumb I always go by is two turns out on the low speed and 2 1/2 turns out on the high speed to start on any engine.
@@westhobbiesrc8051 cool thank u so much u are a good help have a good day and keep u the good work love ur videos
hey hey Gaui NX4, Nice!! stock tail blades are more durable, but I changed it to CF anyway. Is it the stock gear ratio?
Yes, stock gear ratio. OS .37 and 426 mm main blades. Heli is getting Carbon fiber tail blades now.
My plastic blades broke during routine maintenance on my 230s… 😂
Yes they do! Those tail blades are like glass. That’s why I have a carbon tail blade on my 230.
@@westhobbiesrc8051 finding stuff like that in the UK is difficult, only way I can see I can get one is from micro heli and that’s gunna cost me nearly £25 ($30) with postage which seems a bit mental, the plastic ones are £8 for set of two 🤣
If it was a newer heli I’d go for it but this is the older 230s not a V2, and I’m looking to get an OMP this year and retire the 230 🤪
Were they KBDD tail blades?
No, lynx tail blades.
@@westhobbiesrc8051 really were they old or have they been out in the sun to deteriorate the plastic by chance? making them brittle?.
Only reason I ask is cause I have a set of KBDD knock off orange plastic tail blades on my bitsa mongrel child Trex 450.
To be honest I don't mind them but if that's what they are gonna do on a 500 size heli that spins the tail slower than a 450 size heli, I'm a bit worried that they may fail.
Do you have a recommendation for good cheap carbon fibre trex 450 tail blades.
Thanks in advance.
@WestHobbiesRC Are plastic tail blades okay for sport flying or beginners?
A lot of it has to do with how old the plastic is how it was kept or maintained if any Loctite has touched it. On any helicopter that has plastic tail blades, which is only a few ice change them every 50 to 100 flights or so.
@@westhobbiesrc8051 Okay, thanks.
@@massarms4583 your welcome!
I have them on my T-rex 450. You think it's ok? I am not a 3d flyer
I’ve got plastic tail blades on my 470 LM and they have been fine. As long as they’re not old or stored in a very dry/sunny environment where the plastic can get brittle and old. You should be fine.
