HIROBO Freya - Sceadu - Shuttle > Another broken clutch

Ok, this is it this heli has been nothing but a pain in the a#$. This is the 3rd clutch this season. Always had abt. .001 run out have the finest equipment to measure with (I work in a machine shop) At $38.00 a pop I'm done with hirobo. This is the worst luck I've had with a heli. Going with a T-rex 600. I am at my wits end. There, now I feel better!

Before you go away angry, please call Dan Goldstein at MRC and explain your problem. I'll pretty much guarantee you he'll make it right.

Unless you've replaced the bell and/or the liner along with the clutch, you've not addressed the underlying cause of the breakage. Clutch run out has nothing to do with it; clutch to liner gap/clearance DOES.

Wow! This is a strange occurrance. Do you have any resistance on the clutch bell when you spin it with your fingers? Sounds like some sort of "stickage" is happening on the driveline. I have many gallons on my Evo 50 and beat the crap out of it with no clutch issues. This includes a couple of hot starts.

I'm sure MRC will make it right.

Vibration

I went through a bunch of clutches one season. The culprit turned out to be a bad rear engine bearing (ceramic on SS). The bearing did not exhibit the normal rattling sound at idle, but the engine was heating up and losing power. The resulting vibration from a severely worn rear engine bearing destroyed two clutches before I finally found the cause. Since then, I've never had one break.

I noticed that in another thread you observed that your gyro isn't holding well. That also is an indication of a high-speed vibration.

The Evo clutch holds up very well unless you abuse it. I suspect that you have something causing excessive vibrations in the heli.

I have always replaced the clutch and bell as a set. I have replaced the rear bearing and had two clutches break with in 3 wks. I'm tired of this machine breaking down. I need something I can fly without the worries. I will not call MRC. This machine is down the road. Thanks for all the help.

I have had engine bearings fail and did not have to replace the clutch before. Until recently I only replaced the clutches from doing hundreds of autos which is harder on a clutch. I too have had more clutch problems lately. I have had a new clutch engage early which made it difficult to idle the engine down low enough not to drag. In a short period of time I had to replace the clutch.

If this is an engine bearing problem it seems from reading all the other threads about engine bearings that they would also mention having clutch problems?

The only time an auto would be hard on a clutch is if you have to bail out alot? Other wise it should not really matter. Hirobo clutches suck, plain and simple. Should not have to mess with clearance between the bell and clutch. At $38.00 for the clutch and $55.00 for the bell it should be plug and play. IMO

I would suggest you already own one. Find the problem and fix it!

2 EVO 50's here. Both on their 5th year in service. No clutch problems, very low over all maintenance machines.

thanks but I've dumped too much money in this. What problem? Fix what? I've fixed the problem.... got an Align product. Own 2 no problems....ever! If you like yours so much then I'll sell you my air frame dirt cheap.

Gotta love people who fix problems with known downgrades . . . .

If you are serious on parting with it for a good price, PM me what you want for it . . .

Well maybe you should read the T rex 600 section, because if you would have read it you would find out that there are more issues and that they also have clutch problems and oneway failures. But alas go for it and by the way Hirobo Clutches do not suck!Mine is running since 200 flights with bailouts from autos etc and I did not even dial it in, it was plug and play by the way!

Well, yours was made on monday. Mine was made on friday. I guess I have bad luck. I've done all I can with this machine. I'm tired of taking this thing apart every 2-3 weeks thats all. I fly alot and Hirobo products are not up to the challenge. I love it when it does run but thats not very often. So I dont care what people say abt. my comments the Evo 50 sucks its broken more often than not and I will never buy another MRC product again. The old rep would have taken care of this but he is one and a million. Regards...Rob

I think it's apparent to all here sans one, that you DO NOT have a clutch problem. The broken clutch is just the end result. But I guess you know best......

Yes I do know whats best....Align. You have read up on my problems what do you think the problem is besides me loosing my patience? I mean how many things could it be? Runout...no, engine bearings....no, What could it be? I don't want to waste anymore time I should be flying not wrenching. I really mean no disrespect nor am I a know it all but I am a good heli builder and I have lost intrest in the Evo 50.

Eagle2bravo,

When you start off, do you jam the throttle up to half stick or slowly let the system come up to speed by slowly raising the collective?

I've seen a lot folks do this and I'm not saying you did but when it happens like this, you get clutch failures.

From your profile, you own mostly electrics, registered on the forum a little over a year ago so if you don't mind, how long have you been in the hobby? This is not a slam, just trying to get a feel for your experience level and how long you've been flying.

Once again, if you hate it that much, what do you want for it? I have three Hirobos now, and the only failures I have ever had in 6 years or so have been due to "unintentional ground contact" . . . and I would not mind having another!

That was a tail blade issue on a 700. I still hear more good than bad. For those of you who want this POS 150.00 shipped as is, its in the classifieds. We can close this subject now.

Let it go guys. He's used the word "best" and Align in the same sentence. The only thing that Align is "best" at is releasing a model with multiple known flaws, fixing the flaw after a few months, SELLING the fix to the customer, and then somehow making the customer think that Align did them a favor.
