HIROBO Turbulence - SDX - Freya - Sceadu > Hirobo Freya D3 Head = New Life for Freya?

I heard that there is a D3 head assembly available from MRC that will fit on a Freya if it is configured for SWM.

Has anybody done it? Does it enhance its ability to do 3D?

The rotorhead from the D3 is an SSZ-IV.

The Freya does not have to be SWM (mine is HPM).

Along with the R/H, you need the washout slide block and the longer links from the short side of the washout arms to the swashplate. Other than that, the SSZ-IV bolts right on.

Proofread carefully to see if you any words out.

When I get to MRC on Monday I will be sure to check to see if we have any of the discounted conversion heads left.

The SSZ-4 is the best head I have ever flown. Just make sure to drill out the threads in the spacers. With the threads they tend to unscrew themselves in flight which causes unequal blade friction.

I am flying the SSZ-IV head conversion on my Evo Freya. With this head, what can you say? It's like butter...

How's its 3D capabilities?

The SSZ-IV head is one the finest 3D heads on the market today, period. The head offers a tremendous number of set up options allowing the pilot to exactly tune the feel of the head to his or her tastes. The dampening system centers around a floating axle with center teeter support which restrains lead/lag only. The whole head is exceedingly consistent and durable even when flown as hard as anyone would ever care to do. Dominik Haegele used that head on a Freya Evo with SWM conversion to win the 3D Masters in Great Britain.

He could probably do that with a Raptor.

Well, you're saying that even a Freya, when equiped with this head, becomes capable of 3D moves.

But let me jump to the point Dr. Ben. I've been flying for three years and have recently moved into some entry level 3D moves. My Trex 450 and my Vibe 90(non-SG) will do anything I'm capable of doing with them and then they look at me like, "Is that it?" And it is, for now. But I bought this Freya used early on and I've flown it a lot and I've always loved it. However, now as I try to do some moves with it like I do with the other helis, it doesn't want to cooperate - like I'm violating its inherent stability or something. It's about a 2002 vintage Freya with an SSZ-II head so I'm told. So it wasn't meant for 3D flying, really.

I want a Turbulence but that's not going to happen for a while. So, the question is, if I spend a few hundred for a new head will this allow the Freya to do 3D moves? Or is it just too heavy, for example, and it would be better to wait until I can build a capable D3. It's got an SWM conversion and the servos are F 9250's with a 611 gyro, GV-1 gov and OS 91SZ.

Whatch think?

If you put the IV on your model as it's now configured, you be able to learn A LOT of 3D while you save your pennies for a TD3. Your Freya will fly like a completely different model with a IV head on it; I guarantee it.

Hi John Benario

With regards to the blade spacers.

I have had 4 metal head Hirobo machines and never had one come loose.

I use #648 between the spacer and the grip and then #243 on the 'bolt'. I tighten it up as tight as i can with a 7mm allen key.

Works for me. I have had to work to get them off.....I wanted to try RT720 blades and needed to get thinner spacers.

Regards
Paul

Paul,

Therein lies the rub. You've been using the thicker 3T metal spacers. They don't make threaded 2T thinner ones in ali, only the ones that go with the SSZ-V. That upgrade for spacers and drag inserts is $65 or so retail. You can't tighten down on the thinner plastic ones but so tight without stripping them. So far, either upgrade to the V parts, do John's mod, or do mine with the 638 Loctite.

OK - the SSZ-IV has been duly purchased (by my LHS). MRC could explain this better, but I bought a 'kit' put together by MRC to convert a Freya rather than the head assembly offered under part number 0414-455. It's apparently everything from the swash up (excluding the swash itself).

We'll see how it goes!

That's the way to get it. It comes with the head, washout base, new "A' links, a few pushrods, and the phasing ring/clamp.

Let me know if you need any help with final assembly or set up. It's a gorgeous piece of machine work.

Thanks! I probably will need some guidance associated with the positioning options in the head assembly. I've heard that it's very tunable but the instructions are very Hirobo and don't explain the functionality of the tuning options. I haven't seen them though so I don't know for sure.

Hi Dr.Ben

Regarding the spacers....

I forgot, i had my friend machine down the 3mm spacers to 2mm.

The job was quite easy. The silver 'bolt' doesn't thread all the way through the spacer, so we just threaded it together and gripped the 'bolt' in the lathe jaws, with the spacer pressing up against the jaws to keep it nice and straight.

Paul

OTS,

Make sure to get a JIS 000 screwdriver for the little bolts.
