Just wondering the benifits of converting the SSZ-4 to SSZ-5 by replacing the pitch and mixing arms and Stabiliser rod without replacing the blade grips and spindle. I am also planning on using the SDX dampers. I assume the attachment pads for the pitch arms would be the same distance appart regardless of grip type?

Is this possible and would the handling be noticeably different?

Hi Paul,

Using the SSZ-5 mixing arm should give you a little more resolution which is helpful for a tighter setup for hover. Not so much for aero's. Changing the pitch arm will give greater delta offset for better cyclic stability. The SSZ-4 head already has the ability to set some delta offset.

Personally I don't think you will see significant change in flying from switching over to SSZ-V parts. Most of the change will be seen in the hover setup. This all really depends on what you want to get out of your setup. What you intend to use it for.

I used my D3 V1 with SSZ-4 head for F3C before I switched over to my Eagle EP's and it flew really well.

Thanks Bugcatcher

I have just bought a Freya Evolution OPII which comes with the SSZ-IV head. It will be used for sport flying as I wanted a good flybared helicopter. I am putting a 12t clutch and 95t main gear in for 7.9 ratio. The clutch and main gear it comes with are the same as my D3v2 so will be kept as spares.

I enjoy flybared helicopters and their natural feel. I have gone almost entirely back to glow and believe FBL and electric are overrated.

Hi Paul Bowen and Bugcatcher,

I recently unearthed my old backup EX2 SWM SSZ-III. It has OS 91 HZ. Futaba 601. Last flown 2007 Worlds at Wlòclawek. I am having a friend restore it for me since he was also the one who built it then. It started life as an EX2 HPM SSR-VII then converted to 120 degree SWM and SSZ-III more suited to my style.

I now have the opportunity to upgrade to SSZ-IV or V using a new head. My questions are, is the difference worthwhile? which head do you recommend? Should I get a swashplate that has the 135 degree option? Will the rods be different in length? Which other parts need to be replaced?

Thanks!

The SSZ-V head conversion is 0414-518. I'm not sure what other parts are required.

I think I am probably going to convert my Freya from SSZ-IV to SSZ-V. Mine has the SWM EX swash whereas my D3v2 has the later 135 swash. Personally I'm not sure the later swash is essential.

If you have the choose between SSZ-IV and SSZ-V. Always go for the SSZ-V. IF you already have the SSZ-IV then I don't personally see a significant improvement by going to the SSZ-V head.

The only differences are the SSZ-V has

1. Longer spindle and longer blade grips
2. Slightly different blade grip arms that have different delta offset
3. Lastly it has a slightly different mixing arm.

If you wanted you could change the mixing arms and maybe the blade grip arms to get the same effect instead of buying a complete new head.

Also note the Freya is only 120 deg CCPM mixing so no point updating the swash plate with the D3/Eagle 120/135 deg version unless you need to buy a new swashplate anyway. Having the option for future or compatibility is always nice. The newest SSL-II swash plate is not really an option as it is only available as 135 deg unless they have changed it in the new Freya SSL-II kit which i'm trying to find out about.

Does it have 2 options or positions for mounting the ball on the inner ring? If so then it is new part. Going by the part number I think it is which means 0414-576 is really a pointless part now and should be discontinued.

No, that was not what I was meaning.

I was talking about the 2 positions on the inner ring for the link rod that connects to the blade grip arm. The ball was turned 90 deg and has 2 threads to mount the ball on.

I can show a picture of what I mean if you like

I think the answer is in this thread?

https://rc.runryder.com/helicopter/t811245p3/

Looks like there are two holes with thread on the inner swashplate as well. An inner threaded hole as well as an outer hole. Hope this helps.
