Could anyone with a well working flybarless setup post the distance between the balls on the blade grips at zero pitch? It would be great if someone with a HR Stratus could post not only the distance between the blade grip balls, but also how far out the servo horn links sit.

I'm trying to get some arms CNC'ed and this info would help tremendously.

Check out my gallery for more pics of my flybarless Ion X2. The distance between the centre of the headblock and the centre of the ball on the blade grip is 32mm and I am using the longest JR servo arms with the ball on the outer hole (I think that is approx 22mm). It works well.

Here are my two FBL heads.

This on is on my Stratus, it is all MA parts and I used the double balls that are on the stock flybar carrier. The inner ball is 28mm from center and the outer ball is 33mm from center. To be totally honest, I never measured them until today. When I have been flying it on the outer ball and have not noticed any ill tendencies on the cyclics. When the weather breaks, I will move them to the inner balls and see how it works.


This conversion is on my Ion-X2 and uses the QUK Raptor 90 grips. This is a much less costly conversion as it uses ALL the stock bits on the MA head except for the grips. They measure out to 25mm, again, no ill tendencies at all.

I understand that Mikado recommends 30mm as the ideal distance for optimum servo resolution. I have flown both of these set-ups a fair bit and if I am not getting the most out of them I can't tell. That's my two cents.

Lou

PS. Sorry for the delay with the measurements. Let me know if there is anything else I can do.

Just give me five dudes and two flashbangs...

Thanks David and Lou. Sounds like the electronics are pretty forgiving so long as I get within the 25-33mm range.

I think for shear resolution purposes, I'll go ahead and space them out at about 32mm.

All right, I have a grip arm that should fit the Tempest grip perfectly. The balls are spaced 32mm from center and with the ball I chose, there should be zero delta. From the looks of things, it should be plenty strong as there is 7mm of material where it matters.

Out of curiosity, who would be interested in acquiring a set of extended arms assuming they fly perfectly? Buy the arms, tempest grips, a spacer, and some bolts and you could end up with a fairly cheap FBL head that doesn't look so ghetto rigged and can be assured that there is minimal flex in the grips. I was asking because I'm going to make the arms for myself but if there is enough interest, it would be fairly easy to source the project to a CNC shop and be able to drive the price down.

blade grip arms, count me in!

Count me in as well. Hey J what are you using as the swash driver? Those washout arms don't look like MA stuff or is all that Mikado parts?

Kyle, I'm not sure what washout arms you're referring to, but as far as a swash driver, I will either be milling something that looks similar to the Mikado unit or I'll just modify the stock ma washout.

I've been in communication with Wes (DaOne) and it looks like it's going to take an order of 100+ sets to make the price low enough to be worth it. I've also looked into the option of acquiring my own CNC mill and it that happens, I could do small batches at a good price.

I still have some time to investigate further options as I'm about to make a few sets via traditional milling so that I can fly them around on my Stratus and make sure they work properly.

Edit, just realized you're referring to the swash driver on Lou's heli.

Mikado parts

Yes the swash (Washout hub and arms)driver both you and Lou are using look the same, so I assume its Mikados setup there.

Well, since the weather has gotten nice and 4.0 is out... I have been flying my Ion-X2 with the QUK R90 grips. I love it! I have had no issues with the head and all seems to be flying very, very well. I will try to get some new action pics this weekend and post them here or in the FBL forum.

I haven't messed with it ever since I sold my Stratus at the beginning of the year. I ended up calling Tim and spoke about actually having MA make the parts. However, from what they told me, MA has no immediate interest in producing a FBL head. Quite a shame too as I would have handed him the CAD file as long as he gave me arms whenever needed. The other option was to get someone else to CNC them which I inquired to a few shops about and with the low volumes that would be needed, the price would be very steep.

Whenever MA decided to sell me a 50 or a 90 kit, I'll just make them for myself and a friend and will just do it by hand. If all goes well then I may be able to convince MA to start making them.
