I have only been talking about getting one of these for several months now but I think I will get one this week. Are there any upgrades that will reduce headache? Not exactly must have, but eventually need. I am thinking along the lines of the radius block or mixing arms? I am getting the cooling shroud and will have a 9206 on collective. 401 gyro. v-blades and maybe MS tail blades. I did a search but don't really see anything other than woof problems. Is the stock radius block better or the same as the Freya?

I would suggest flipping the head out of the box,reinstalled brass-eyelets and throw away the metal plates.Install a Rap 60 (550cc) tank and buy extra mixing arms,they will not break unless you impact the ground.Also I flipped the tail for leading edge control.Jason Kalbfleisch

cnsheets-When you flip the head you completely eliminate the possibility of flutter,then you can put some vibration dampening back into the servo by reinstalling the eyelets,that is unless you like replacing servos or gearsets on a regular basis.I also forgot to mention getting a set of wider landing gear,I am using Rap 60 gear,about 1/2 the cost of Tuff-Strut 2's.Jason Kalbfleisch

Can you please post a picture on how a "flipped" head looks like?

Thanks!

ycwoon- will borrow our camera from work do not have one at home.Whats involved is flipping the blade grips so their on the leading section of the blade,turning over the flybar and reinstalling the mixing arms backwards and readjusting the rods,also revering your collective servo.The one thing I noticed is Hirobo molded in recesses for nuts on the top and bottom of the blade grips-possibly they knew this would be a problem.Unlike the Raptor 30,every arm that is reversed is symmetrical(all the holes are inline with one another)so you have exactly the same collective feel as before the flip,because none of the geometry was screwed around with.A good flying friend did exactly the same with his Freya 91 on the 2nd flight he had flutter(both head and tail were reversed)IMO think it would be absolutely stupid to take away the little bit of dampening provided by the servo grommets,I have had enough servo failures with the dampening in place.I believe the plate modification was just a quick fix on Hirobo's end.Jason Kalbfleisch

The latest on Sceadu upgrades?
Hello gang,,

Although I am not flying a skidoo I have to add a few things as my freya had the flutters. I agree with Jason in that the head should be flipped as it just "should" be that way in the first place! It is very easy to do and the mixer arms are symmetrical so you loose nothing other than about 20min to do the swap over. The only adverse thing is that the blade bolts are upside down so the hex end is on the bottom which is no biggie either. I also agree that cranking down on the servo is a bad idea, where does the vibration go? I can post some pics of the freya head swap if you want also.
Anyway, my 2cents worth,,
cheers,,
Troy

Blade flip...
Semi,
Great heli and your choice of equimpment looks good. I would suggest the metal radius block and washout ala Eagle blue bits stash. The mainshaft is the same as the Freya line so the upgraded blocks work fine. They are not really needed as the Sceadu has a "knurled" section for the radius block to hold onto unlike the Freya, but they look nice and to me that is a part that should be rock solid so I did it.
I also bought the metal birdcage and mixing arms. I felt that area of the head had some slop in in it and the metal upgrades reduced it. No appreciable change in the flying, but again just a "feel good" mod.
The wide gear is another that is nice to have. I just turned mine around backwards to avoid the bumping of the tail on spool up and the bench. The stock ones work good for me, but if you are not real steady lifting off or setting down a wider set will be a welcome addition.
As for flipping the head.....Well if you really want to go through that hassle go for it. Personally I don't think it is necessary and the flutter problem is simply due to "flexy" blades and a "flexy" collective mount.
I think taking a ship that fly's as well as the Sceadu out of the box and instantly start messing with the design of the heli is kind of defeating the purpose. If you want to do that then get a Raptor.
BTW for what it is worth I had done the "head flip" on my Raptor. Tried it for a couple weeks and didn't notice a difference at all. Next crash it went back to the original design.
As for cranking down the collective. If you install the metal plates correctly the servo still retains it's small amount of flex for absorbing vibrations.

If you are getting the 50 kit make sure you pick up a good 60 sized muffler. They OS50 really likes that.

Other than that take your time puttting it together and you will love it.

Stock
Why don't you get the Sceadu 50 and fly it in the stock form. Then waste you money on upgrades, but do the upgrades one at a time so you'll know it was a waste of money. Buy a Raptor and then you'll know you have to spend money on upgrades.

Excellent advice!
BTW. It flys great out of the box.

I didn't know about the grip flip. The reason I want a sceadu is to get away from all that raptor crap. I have a raptor that I have had for awhile and I converted to a 50 and I wish I had just left it a 30 and bought a 50. It was supposed to help me progress more but I am always fighting problem after problem. The 30 was a reliable and nice ship but the 50 has brought about all the evil raptor problems. I did the grip flip on the raptor to get rid of woof. It did not work (its better but not fixed). Now I am going to try metal grips. The reason I ask about upgrades is because I have a raptor . It sounds like woof is a serious issue with the sceadu as well? I have a Freya and I like it but I did another dumb thing in that I converted it to a 90 at the same time I converted the Raptor. The engine is going great except that the red tubing that goes to the pump keeps splitting and allowing the engine to lean. This has been some summer of flying . So I need a new heli to add to the headaches . What about these metal mixing arms? They complain about the plastic ones breaking at odd times.

flipping tail blades grips
I don't believe flipping the tail blade grips will have any effect other than changing the geometry. There is no damping on the tail rotor hub so the blades can't woof/poof like the mains. They tail rotor hub must be able to move about the tail shaft in order to make the blades go out of track. Kinda like the older x-cell tails.
A main blade that has a tendency to go out of track be forced even more out of track with the push rod on the trailing edge. The blade is forced more positive if it is already going positive and more negative if its going negative.
With the pushrod on the front of the blades, the blades are forced towards zero degrees. Thats why some of the helicopters don't have the woof and puff problems.
Take your helicopter with the pushrodd on the trailing edge and push one blade up and the other down so that the rotor head pivots in the dampers. You can see as the rotor blades move tend to head away from zero degrees.

Every time I have seen flutter problems was due to a loose servo, weak servo, MS blades(I have also see V-blades do the same with a weak servo), or too much slop in the control system.

What is the ideal muffler? The name Hattori 666 gets thrown around a lot. I have a R50 muffler on the R50 conversion and it is ok but the needles on that engine are still pretty sensitive but it should be well broken in by now.

Flip the blade grips, what the hell for??? This ain't no fricken Raptor. If you have a woof problem you screwed up somewhere when you built it.

The Sceadu is fine, as long as you assemble it right, cnsheets is spot on here!

If you want upgrades, I like having the metal seesaw arms. The stock ones do break easily. But as was said they only break if you goof.

Don't go spending a ton of money as you don't need to. Fly it and see if you like it as is.

You heard all this already, now you heard it from me too. Sounds like you have already spent to much on stuff you don't need when you got the Raptor.

No, I flew my raptor stock for awhile. I did have the ace metal swash which started to get sloppy so I added the Quick UK swash. The washout base is now a $10 metal item. I then used carbon viber fins to help fix a gyro stall problem. I did wish I left it a 30 but other than that my upgrades have been fairly tame. I hated the idea of adding metal blade grips but that is the last idea I have heard to get rid of woof. The grip flip seemed to cure it until yesterday. And I think they are on to something with the grips because I do notice up and down play. But everyone that sees my raptor thinks its stock until they see the red swash and then they start looking around. I will try the Sceadu stock. I just remember when I got my Freya that a lot of people said to get the upgrade radius block to reduce headaches and I didn't know if there were such upgrades recommended for the sceadu other than the cooling shroud. I'll leave it stock. Thanks.

Sceadu 50
Build it true and fly it stock and see how you like it before spending $$$'s on upgrades.

Good Luck and have FUN.

FMA???
cnsheets,
Is that a co-pilot I spy on the tailboom? How well does it work back there?

SENECA,
Your going to have to change all those "purple bits" to blue if you want to be uniform with the new upgrades. They are the "higher" quality "blue bits"....
