How many tail servos have failed?

[TDMModels]

22 flights on mine before failure. Piro'ed and went in.
Contacted HH via online form.. Told me too bad...
The guy was actually rude.. said "read your manual".
I've called them before on another heli and they were glad to send a replacement.
I won't bother with online request again.
Fortunately I had a 76T in my parts supply.

So that tail waggle on the 300x; This is the question I asked my local hobby shop owner after we took up the 300x for a short flight in his parking lot. The response I got was "probably normal, its a new bird and that's just some flight characteristics of the new beast system." As I am only 3 months into this hobby; no crashes I might add, I took his advice and shrugged the waggle off as "flight characteristics". That night while flying with a worker at his shop and the rest of our crew I took up the 450 first; flew just fine. Then took up the 300x. It did the tail waggle as before. After a 2min or less flight I set it down near, "20 feet" from the guys and I as I usually do, then on the second lift off about 5 seconds and 5 feet in the air it lost rudder and smashed into a friends truck, but also came one inch from the back of my friend's wife's head. TOTAL LOSS OF THE BIRD.
HOW IN THE WORLD CAN BLADE OR E-FLITE OR WHOEVER PUTS OUT THIS BIRD SLEEP AT NIGHT KNOWING THAT PLASTIC SERVOS WILL FAIL IN THIS HELI !!!!
I have grounded my 450x and 450 3D until new MG servos come in the mail.

Sorry to hear about the close call. First and foremost, it is great that no one was injured.

Second, 3 months of flying CP helis and this is your first crash is outstanding!! Most don't have the patience that you've demonstrated in learning to fly CP..

Tail wag is not normal. The normal cure for this is to reduce the gyro gain, or find the source of vibration, or the problem causing the wag. Sometimes parts can fail. This is why it is always good to try to fly with a good safety buffer, 'just in case'..
Would the servo had failed if the wag didn't exist? I only ask, because there are a huge number of folks using this servo with no problems, on the 450 3d, 450x, and 300x.
You have both a 3d and an X, and the servo is not wagging and I assume has been good.

Be sure to report your experience to HH though, as they are the only ones who can determine if there really is a QC issue with the servos, (based on number of issues reported vs distribution figures etc).. It is possible that the 300x servo you got was defective from the start. Give their customer service a chance to help..

This was the 4th flight of the hell, the 300x was 5 days old. I don't know how to tell if it was anything but the servo. I have now learned about the gain settings in the beast-x, and I had not turned it down from factory settings.
Thanks for the nod to no crashes as of yet; I am a safe flyer and really just like to cruse my choppers. I am training to take up motion picture cameras for cinema photography.
I was all set to pick up the BLADE 500x but now I think I'm moving on to t-rex land as much as I wanted to stay with BLADE, but cant trust those guys anymore. I wish I would have known about those darn plastic servos before any of this happened, I really didn't want to buy my friend a new hood for his truck.
ALL in ALL this little heli has been a $1200.00 dollar lesson in how awesome of a company HH is ... NOT !!!!!!
Again thanks for the tip, and I must say this is a great place to learn about this great hobby !!!

I wonder why the tail servos would be more prone to fail on the 300X? I have close to 800 flights on my Blade 450 with the same tail servo and have never had an issue? There must be something mechanical that is different?

[Hexperience]

I think it may just be a bad batch of servos if the 450 hasn't really seen a lot of failures. Mine failed as a lot of the others, not by stripped gears, just dead. In my case anyway, it seems to be electrical rather than mechanical.

[mixfisto]

My tail servo is still fine, but I had an elevator servo go out on me the other day. I was doing easy sport flying and she started acting 'wonky'. I took her down, looked her over, couldnt find anything wrong. Put her back up, still wonky, but after about 10 seconds, it got worse and she flipped upside-down and flew about 50' and crashed... luckily I was half prepared for this and hit TH. No damage, but after really checking her out, noticed elevator servo was completely dead.

[MAGNUSS]

Wow I thought this would not happen to me. But after my 3rd. flight it locked up on me and crashed. Lucky for me it was only 4 feet high and only thing that broke was my skids Called HH and guy said it was the first time someone was calling regarding that problem. He also mentioned that he was going to send me a servo as a one time for free courtesy They need to upgrade those tail servos. I have a Blade 450x and no issues flown that 30 times no issues weird maybe I got a lemon tail servo ?

[taildragon]

4 feet off the ground started to tail wag and rotate uncontrolably. The hard landing caused a blade strike shearing the head bolt and stripping the main gear. HH sent a new tail servo within 3 days which was excellent. Replaced all the bad parts and set the tail servo end points 16 flights later all is well.

[CousinLarry]

I just received my Blade replacement tail servo today from HH.

Who wants it?! hahaaa

I already replaced with a Savox, I don't want it.

[mixfisto]

Hmm.. pm sent

[john2kx]

My tail servo failed last week. Just locked up between flights. No crashes on this machine. It feels as though it has burned internally, as it wont rotate at all.

A flying partner is just starting to get the wag in his (no vibs in heli) , just looks like the gain is turned up too high). It appears that the wag is the early sign it's about to go????

My LHS pulled a servo off a NIB 300 to get me flying again but I'm looking for a replacement. I've had nothing but good service out of hitechs in the past and am going to try the 5084MG suggested in another post.

[bk.heli.man]

I have had my 300 for about 2 weeks now and 23 flights on it. ( No crashes btw) Last time I was out I was getting the tail wag...I messed with the tx gyro settings (lowered it to about 74%) and the wag got worse...I landed immediately with no damage. I came home and searched 300x tail wag and have come across this forum. Now I don't want to go back out and fly in fear of a tail servo failure and ultimately a crash. Looks like I'll be calling HH....UGH!!!

[mixfisto]

BKHeli, maybe try moving the tail servo around with TH on for a couple mins and see what happens. If its about to fail, I'm guessing it will fail pretty quickly (had a cyclic go on me last week, went from fine to dead in about 60 seconds).

I would also contact HH and let them know your tail servo went out...they should send you a new one.

[Pygmaeus]

Tail servo failed on second flight. Noticed that on power up the servo was is constant motion, almost like a high speed jitter. Sevo would get extremely hot sitting on the bench. Horizon gave me the lame excuse "servos get warm". I flew it, it failed, of corse horizon was back ordered. Installed ds76 and changed by servo setting. Flys rock solid.

[Debo42]

Add me to the list. About 20 flights, no crashes. Got the wag, then it died. Already had a jr replacement waiting. My 450x with the same servo has been problem free, and has at least 70 flights with 2 crashes.

Thanks mixfisto...What do you mean exactly by trying to move the servo? Just try to move the tail pushrod with the heli plugged in? I dont see what this will do??

I had a set of yellow tail blades on it and thought I could try the stock ones before calling HH, Most of the tail vibes and wag are gone but now the tail seems to be glitching on clockwise circles, I will be calling HH tomorrow and will post back what they say...

I meant to say move the servo via the rudder stick on your tx... or you could probably just move/turn the heli left/right to work the servo (while its trying to keep the tail 'inline'). Basically I'm thinking that if the servo is about to go bad, once it's being used/active, it shouldn't take more than a min or two to fail.

[CousinLarry]

I have a brand new tail servo that HH sent me to replace mine.. But I replaced with Savox already and not looking back.

Anyone want a brand new in package tail servo? $20 shipped/paypald. Shoot me a PM if you want it!

[taildragon]

Got a replacement tail servo from HH since the original one died. It lasted about a week(10 flights). Servo maxed out in one direction during spool up, luckily I didn't get off the ground. Took the Heli in the garage and I could hear what sounded like bacon frying in a pan. I will not use another tail servo from HH.
