HIROBO Freya - Sceadu - Shuttle > tooth decay sceadu

I hear many tales of sceadu's loosing teeth on the main gear,
Is this just on the 50 or are the 30's suffering too??

I've got a 30 and I bought the 3rd bearing block for it just to stop it happening anyway, best to be safe first, then coff up alot of money later on. I found on mine there was a little play a the bottom of the main shaft before I fitted the extra bearing, but now there is no movement what so ever.

Agreed!!

If you try to twist the frame, you'll see that it isn't really that hard to do. The 3rd bearing block is in the center of the frame, at the bottom of the main shaft.........and it is in the perfect place to add alot of rigidity. Most are adding it as a preventative measure, before they strip the gear.................Hirobo is adding it as standard on all Sceadu 50 US kits.

If you don't have it already, it is a cheap "band aid" that will save alot more than it costs.

Thanks Guys,

I'd love to fit one, I've had one on order for THREE weeks.
As most of the developed world consider the bearing block to be "the bit that should have been standard" (not upgrade)
It now appears to have become a saught after commodity which is as rare as rocking horse ****.

I've only flown four tanks and already the side frames have a white deposit on them, I think the bird will remain grounded until I can get my hands on the bearing.

I had similar grief back in the eighties with the first release of the concept 30.
I swore then I would not buy a model until it had been around for a year and that I would never again be a heli manufacturers off site testing facility. Ooops Seems I forgot to take my own advice.

I love this hobby!!
As the saying goes......if you want a guarentee....buy a toaster!

Don't feel bad....

Scooby,
You are not alone. All of us here in the US are waiting (some patiently) for the gears and third bearing block.
Jeff G. from MRC says next week. Sounds like Hirobo is behind the power curve on this one.
My Sceadu is showing the same signs. Just watched one come apart in mid flight last weekend so I too am grounding mine till the gear get's here.
Just out of curiosity are you flying the 50 or the 30 size kit?
Had some input from a fellow flyer that the "dust" might just be normal run in stuff. I don't want to take the chance will all the problems the 50 has had with that gear.

I talked to a guy at Altech who said the gear dust was somewhat normal, as the main gear is a wear related item. The third bearing block was an acceptable solution to reduce some of that wear, and the DTDS was mostly for the driven tail. He said the rapid transfer of info on the internet has scared people into thinking that the Sceadu is a crash magnet, but the number of real crashes that had heard about was minimal in comparison to the birds being flown. If this is the only problem my 50 has I'll be glad... no woofing, poofing, clutching, whatever. And we get the driven tail out of the deal. As for the gear rationalization, I take it with a grain of salt. The 30 might be fine without the hopups (conjecture mode on) but I like the security factor more than the actual "I have a problem" mental construct. Kind of like a header tank. Most helicopters will fly fine without one (this is a vague analogy, so try not to pick it apart too much) but the added mental and actual benefits outweigh the cost. Same thing with the gear and block. Mine is on backorder too. I'm done rambling. I'm going flying.

Thanks, John Cadwell

The gear....

The gear is a very real issue on the 50 powered ships. Witnessed one come apart in very mild 3d this past weekend. Hirobo pilot who is one of the best in my opinion doing simple tail first flight in Idle 1. As for it scaring the buyers. NO WAY. Just a simple thing to get adressed. I would buy one again tomorrow.

Mine is grounded till the upgrade get's here. I never saw my Freya generate that kind of dust when I installed a new gear after a crash. Should be the same kind of material, but I believe it is not. The Freya gear seems much beefier and of a more dense plastic.

Oh well Hirobo is "fixing" the problem that is all I can ask for. I love the machine otherwise.

I have not seen or heard of any mixing arm problems. The elevator links have broken during "sizing" on a ship I know of. I thought they were made out of a kind of brittle plastic in my opinion. How long do you think it will take for someone to make a metal set of those anyhow? I would bet by summer we see all kinds of shiny bits to put on the Sceadu.

I'm not arguing that it doesn't happen, nor that it shouldn't be fixed. I would by my sceadu again in a heartbeat as well. Great ship. If this is all that ever happens, thank God. As for metal ball links, what would they be made out of? Alu? Seems a little soft for popping on and off. The part I would like to see more is a captive ball link that is still easy to get off. Like maybe a beefier link made of metal, some sort of bushing insert for the ball... not sure. Just to keep them from failing or popping off in flight. What usually fails? Do they pop off, or do they break at the top? If the top, then a beefier link. If the pop, then maybe some sort of screw in washer that keeps the link captive. How often do most people take off their links? I check them, but I rarely pop them all they way off on my setup sceadu. Then again it only has two gallons on it.

Thanks, John Cadwell

Links,,,,

Haven't heard of a problem. I know mine are not coming off. I did have to size them with a ball link tool to get the correct fit.
I take mine off with a cheap set of ball link pliers. If you don't have a set get one. Get the long nosed ones though not the cheap Revolution ones. They have a hard time getting into the Sceadu's tight spots.

Noticed you are on the other side of the state. You should try to come over to the Fun fly in Bellevue this year. The club at Marrymoore is trying to get one organized. Drpp DJensen an note here on Run ruyder. He is the POC. He can add you to the list.

I had to size mine too, and I do have the pliers. Can't imagine what life would be like otherwise. As for the funfly, it sounds like fun. However, I have never flown with another pilot before

Kind of used to having the air to myself... Just got another friend hooked today, hopefully I'll get some practice missing helicopters.

You must go.....

John,
I am not one to fly with a crowd either, but the experience is worth it. Lot's of fun to see all the different stuff.
Learn alot about you particular heli also.
Plus let's not forget the prizes!!!!!!!

I don't think Marymoore will be that crowded. Not like Vegsa 90 pilots that was "combat flying" as one of the guys from my neck of the woods put it.

Tjhey are coming

Hey dudes

The parts will be here for sure next week. I got confirmation they left Japan. Hopefully Monday or tuesday. Shipping will commence immediately, oldest orders first, but all that sent in info should get there's first as they are first priority for me.

Thansk for your patience guys. It was a tall order trust me.

I'm a Robbe flyer (don't throw anything...) and have been helping a new flyer with his Scooby .50. I really like this bird except for a few items that (most, at least) seem to have been addressed! Carl ( the new guy)doesn't have the 3rd bearing block yet and while looking at the design of the bottom end of the heli I was struck by how much flex there is in the frame! I believe this may be the cause of a lot of the main gear probs I have read about, the Robbe Milli 1 had the same problem! The way I stiffened up the lower end of the Scooby was to put a ailuminum stifferner (1/16"thick) under both the front and rear landing gear! Each stiffener goes under each L/G cross strut and is bolted on with the same 3mm bolts, then you drill a hole in the middle of the cross strut and the stiffener and bolt it together in the center! The botton end of the heli is now stiff and flex-free! The flex that was evident when holding the rotor head and twisting the frame of the heli is gone, I think this might have been contributing to some of the gear probs that people are having...though the plastic in the main gear is a bit ...wanting...the main gear in Shuttles (flown them since '85) is more robust! I might just have to get one of these critters myself... Chris

The plastic stacked frames do flex a bit, particularly by nature of
the design where the 2 bearings are fairly close together providing
a high 'moment' for the flex.

On this machine and on the Freya, the 3rd block really stiffens things
up and also, on the Freya, another flaw is that the engine mount uses
the engine case itself as a structural member which isn't a good idea
but does save a few $$ on the cost of a machined mount.

Interesting piece of info I heard -

The reason that Hirobo do not include the 3rd bearing block in their kits is that they have to pay Kalt a fee for using their patented design. This is why all Hirobo helis including the top of the range Eagles do not include the 3rd bearing blocks. It seem selling it as an upgrade is okay and gets around paying the fee.

Is this true or totally bull****? Can anyone confirm?

sounds like total BS.

Now excuse me, I hvae to go off and collect royalties for that 'wheel' thing I invented.

Maybe, some beancounter decided that in most cases, it wasn't
required and the company saved a few dollars on every kit by not
including it. Worst case scenario: beancounter is wrong and
the company decides to now include it for zero additional cost or short increase. Company is hailed for good responsive customer service.
Contrast that w/ JR who took a while (and very begrudingly I might add)
to acknowledge the problems w/ the Vigor when it was introduced.

Man are you guys cynical

) I believe Taya patented the design in Japan where everything they do is basically different than here. Their patent laws are more than likely different than ours unless a Japanese patent lawyer can confirm this other wise. They do include it on the high end machines but do not install a bearing. I guess if the machines were perfect we' d all have to find something else to complain about.

he he he he he.
