please check out the links, see the kit contents of each head.

any help will be appreciated,

thanks in advance

The G-Force head is also very nice

I prefer the Kasama, here's why.

Three contact/pressure points on the main shaft (the G-Force looks like it has it as well). Jesus bolt and two crimp points where the washout pins go to the washout assembly.

Pitch arms are a R/I (remove/install) component. If you tweak the head and the arms get bent, you only have to replace the arms. On the QUK, the entire blade grip is one piece, you have to replace the entire grip.

I haven't finished "throwing" mine around yet, but so far I like the Kasama head. Response is great. I'm still testing and dialing it in but it's definitely a keeper. I haven't seen a G-Force in person or flying, but it looks similar. The only draw back with the Kasama I saw was the delay in getting the parts. However, I usually buy a component and a couple spares so the initial delay is not the bad for me. I typically "forecast" needed parts and stockpile them for the life cycle of my models, my basement is like a small hobby shop.

This is my video of my raptor 50 with the g-force head. I'll have a more impressive video soon, using the g-force mixing arms and 14 degrees +- of pitch!

Just put this Kasama on my E Rappy, looks nice, only had to add an extra "thin" washer behind the one provided for the bottom mixer to bring out and make it feel much more free, other than it was nice fit.

Ummmm wow that head is gorgeous!!! :WOW

[bgjames111]

I still stand by the g-force head. 360 degree damping, no center pin. and adjustability that you wont get anywhere else. Maybe not as pretty as the kasama, but i'd rather have performance over glamour. The "o"ring damper set up is a really nice design. Notice how several "high end" heli's use "o"ring dampers?...vibe for instance?

Flew my Kasama head on my Raptor today. After a couple flights shaking out the cobwebs, I was impressed with the head's performance. I'm running 13/13 w/ 7 cyclic. Head was responsive and I was running a variety of head speeds to get a feel for it. I haven't tried the G-Force, so I can't comment on it.

[Crazy geezer]

wow, full 13+/- must be an absolute rocket, 7 degrees cyclic?? how do you measure how much cyclic degree you have??

[ClayK]

Use a pitch gauge and measure aileron and elevator inputs, similar to how you gauge pitch but not exactly. Check out Finless Bob's CCPM setup videos. Raptor 50 is mechanical, but the information is good nonetheless.

13/13 is nothing, 14-15 is what the Gforce products can offer! :mrgreen:

[OICU812]

How come they do not sell a complete head kit? G Force that is? I see the Headblock seperate and some arms etc....

[bgjames111]

I have talked at length with G-Force about this and they offer what the felt was important. There are currently the Headblock, the mixing arms, and the flybar cage available now. There are some more parts coming. The headblock and mixing arms give the performance bump, the rest is pretty much bling.

[ClayK]

My question would be why it's not packaged as a complete assembly as well as being separate components, I think that's what Shawn was asking as well but I could be wrong. Just curious. I'm not opposed to trying different head/mixing systems to see what fits how I fly.

Typically, manufacturers will package multiple components into a larger assembly and also deliver a discount versus purchasing each separately. This is of course in addition to providing each component separately for those consumers that don't want everything.

[JeepCJ]

I'm waiting for the G-Force cage, I have the headblock, and mixing arms on my Titan. I can't comment on the Kasama head, but the G-Force was well worth it! The cyclic is alot more crisp and accurate. Tracking it great.
I am getting a slight pitch down when in FF with full collective, but my EVO does the same thing. I think that is becuase of the plastic still left in the head flexing.
Night and day difference over the stock head, and even the EVO (that has a metal head block, washout base, and phase ring on it)

Bob

[torkboy]

I dont know why they arent offering packages, maybe some time in the futue? Yes there are more parts comin out in the future, inlcuding the 450, and 600!

[JeepCJ]

I think they are going to in the future. I don't think all the parts are ready yet.

But, by not offering a "package" with what they currently have they are losing potential customers. If I were to buy all 3 of the current G-Force offerings it would cost $160. That is the same price as the entire Kasama head minus the grips so I essentially get a nice metal washout set for free. I looked at the G-Force stuff but for the price I'm going with the Kasama setup minus the grips.

[SuperFatCat]

GScott,

Not a apple-to-apple to comparision.

Our heads use triple orings for dampening, so you need to add $19. to the competitor's product to use orings as well.

We have oversize button heads using two bolts to secure it, the phasing block is adjustable.

Our mixing arms have 5 holes for 6 tuning combinations.

The flybar cage is tuneable and is a full cage.

Out of the box, our heads do not have low speed vibrations, bobble, wobble, teetering.

Actually I don't need to add the $19 since I will use the my current set of Infinivation dampers. The extra tuning may ne nice but there are not enough of these heads out there to see if it really is a benefit. In the end it doesn't really matter. If G-Force had a similar "package" to the Kasama then I may have gone that route but they didn't and judging by your response you don't feel you need to. That's not intended as a flame or criticism and if that's how you feel I have no issue with it. Just realize not everyone will agree.

[OICU812]

Regardless of what is bling and what is not, I would have definetly considered the G Force head if there was a combo kit of some sort offered with everything I needed in it. I did not want to find or proce out seperate components which is why I bought the Kasama head to begn with, I must be a lazy shopper, lol. None the less I am not really impressed with my Kasama head so I will watch for updates with the G Force head etc...

[JeepCJ]

When I looked at the G-Force head, I was not looking for a package, as I did not plan on going to metal grips anyways. I was more interested in the damping system, three bolt mounting system, and the adjustability of it. It works, as I am sure the Kasama head does also. The folks at G-Force are also great to talk to.

[OICU812]

Bpb, How much collective and cyclic do you run on your G Force head and what kind of wear do you see on the o rings? Wondering how exactly that system works in regards to the o rings versus runnig the dampers....

[JeepCJ]

I am running +/-12 right now, and I have about 25 flights on it. I have not pulled the head apart to check for wear yet. But will soon. I am running 70/90/90 with the air temp around 45-50 degrees. It's flying fantastic right now, and I plan on bumping the collective to +/-13 and some more cyclic (running 7 degrees right now) After I install the 8.7 gear ratio. It does not bog much right now, mostly only when I get scared. :mrgreen:

[SuperFatCat]

I need feedback as to the bundling since you folks are the customers. Although the head, mixers and flybar cage contribute to the most performance, that could be a bundle itself and another including the blade grips for those that want it all.

We sold them as components because of earlier feedbacks that not eveyone wanted to buy a full head but the components as needed along the way.

The blade grips are coming out in Jan 2007 and they will be tuneable and are symetrical for 3D flying.
