Kasama Head for the Trex600N

[Finless]

Ed from Grand RC sent me this little gem so I thought I would give it a try and also do some build videos on it. The design of this head is VERY different than the Trex head and some special setups need to be paid attention too.


Enjoy

When I get back from Hawaii I will do some flying with it and see how it works and how different it is than the stock Trex600 head.

OK sorry folks for the LONG delay in getting a flight test video out! Vacation, Illness, Rain, Winds, etc delayed it BUT last weekend we got to do some testing. Bottom line this head is a ZERO slop system and feels very connected and agressive! The roll rate was a little slower than the Align head but the flip rate was faster (strange I know) but the over all feeling of the head is very good. I plan to keep it on my 600N!

Here is the video!

I wish to thank you for all the help you give to us and the hobby....You are IMHO one of the best resourses there is...Thanks again Bob G Florida

Nice work Bob - can't wait to hear your report on how it flies - looks nice has a sort of scale feel to it being lower set than the stock - could be a great basis for a flybarless setup! The new QuickUK silver swash (http://www.quickuk.co.uk/acatalog/r_index.htm)would look nice with it !!

We use silicone oil a lot in surgical instruments - use it on O-rings in endoscopes - great lubricant - does cause them to swell a little which is how it helps seal as well as lubricate.

[BarnOwl]

John, are you talking about the regular silicon oil found in spraycans or is this a special silicon oil you're referring to? (I know it would be special for surgical instruments, but the one to use for the swash a.o.)

Hi Bob,

if you were to have some time for it I would be interested to know if the head fits the raptor 50's also, and the e620.

Maybe I'm not the only one but I'd like to know what pitch and cyclic ranges it gets without binding on raptors. just as a comparison to the normal raptor kasama head.

thanks a lot

[Mercuriell]

No Jeroen - not the regular spray stuff - its a clear very viscous liquid also available in grease form - swimming pool suppliers keep it for o-ring lube here but I guess there's not too many of those in The Netherlands :) - if you like I can send you some

Hello,

I just watched the build videos.
Very nice. I enjoy watching these videos even if i don`t build the specific parts just so i can learn from them.
Your video about the Kasama Head for the Raptor helped me a lot when I was building mine.

I just want to add something.
If you more the ball link on the mixing lever wouldn`t that give you a bigger pitch range ?
Thus avoiding the bind on max negativ pitch and maybe even allowing the full +-14 pitch range.

It`s just an idea and i wanted to know if it was correct or not...

Thank You again for these great videos :)

Sounds like it might be similar to this stuff, which is kinda viscous. Foosball tables have soft rubber bushings on the rods, and wd-40 is definitely a time-honored disaster there.

I carry around one of these with me most of the time... :-) I could put a drop on some glass and tell you how fast it runs or something... :-)

[mattkreps]

I would like to get one for mine. Can you do some flight testing with vids please

[cyanide1973]

I'm also wondering if it will fit a raptor 50 does anyone know?

[Iceman575]

I looked it up and it looks like it also fits the Raptor 50.

I have the old Kasama head for the Raptor and if this one is at least as good as the old one it`s worth every $

ahh I can see you definatly a smoker Bob

Excellent - my orders gone in - thank you very much Ed - have the QuickUK swash (http://www.quickuk.co.uk/acatalog/r_index.htm)to go with it - just need a V-Bar now !!

OK, I'll bite: is this head particularly easy to make flybarless? What all mods does it take?

EDIT: and while I'm at it: what are the advantages of the QuickUK swash over the new Align alloy one?
EDIT2: OK, I've read the QuickUK page on the new swash. I see the point :thumbup:

Not real sure but from Bob's videos the rotor head sits lower than the Align so starting to look more scale anyway (unless you fly RObison's) so I figure go all the way with a V-Bar - think the Mikado swash anchor blocks should work - WIP !!

[matrix1171]

so, um...... Finless do you have a flight report on the new head yet.... I'm sure many of us are curious as to how it flies now. i know i am:thumbup::YeaBaby:

[TheBum]

He's probably still sobering up after all those Mai Tais.

[Finless]

I caught the COLD from hell and lost my voice even!
But last weekend was rainy anyway. Hopefully I will get some flying on the head thsi weekend!

Bob

[matrix1171]

that sucks about the cold..... those little buggers tend to show up when you don't want them too and i'll be starting the build on mine soon...... getting a pro for Christmas :thumbup::YeaBaby: and I'm totally stoked about it:banana:clappp

I just bought one of these heads for my 600E (head is identical to the N so there is no reason it should not work...I hope) hoping it will allow more cyclic (we will see).

I havn't got it yet as I just ordered it however I would like to thank both Finless for the videos, and GrandRC.com for helping Finless get the equipment to review AND a discount on the head. $60 off was the final straw in my decision to get this head .

Had me scared when I heard there was a mainshaft modification required but its really minor (and I will do it aswell).

The oiler hole is a very nice touch on this head to allow me to lube periodically without dissassembly. Great idea.

I'm very curious to hear a review of the head and how its flight characteristics vary from the Stock 600 head.

[Iceman575]

Hello,

So any updates ?
How does it fly? I`m really considering to get one but i already have the whole head metal with align parts.

Is it worth it ?

[Finless]

I still have not flown it. Rainy weekends and me having walking ponemonia kept me from flying. Stay tuned I will get to it :)

So I've recieved my head and assembled it. One thing that comes to mind is when measuring my pitch if the flybar is angled (not level) then it skews the reading on my pitch gauge. In order for me to set it I need to use 2 levels on my paddles to make sure my flybar is level before checking my pitch. Easy enough to do however it confused me for 5 minutes.

The kasama head appears to be VERY similar to the Avant Aurora head does it not.

[Ralphw]

Got mine in the air today for the first time. A GREAT way to exit '07 :YeaBaby:!!

I had the stock head with metal grips and the "new" swash all set up and working well, but the new Kasama with the Quick UK swash is (even for my dumb thumbs) VERY responsive :shock:. It flips faster, rolls quicker and overall was a noticeable improvement.

I've only found a couple of things I wasn't totally happy about and they are minor...first was the lack of an assembly instruction sheet to be used in conjunction with the exploded view (still pretty self explanatory, but I was really glad to have Bob's videos to clear some things up....Thank You Bob :noteworthy). Second was the way the head acted in wind (about 15mph today). It wanted to drift INTO the wind during hover instead of setting or drifting downwind. I suspect there is some adjusting that I will need to work on for this one...probably moving the balls on the mixers (Bell?) or the mixers themselves on the grip arms (some kind of Delta adjustment??).

Overall, an awesome head and it totally lives up to the Kasama reputation for quality and performance.
