Kasama Head and Tail for Raptors

[smeede]

Hi Bob, Thanks for your help. I don't know if I explained my problem incorrectly (new to helis) but I have full pitch range pos/neg. At full pos pitch the washout base is approx. 2 mm (below) from hitting the main rotor hub and at full neg the bottom of the swash is approx 6 mm from the main shaft lock ring. I can move the collective pitch arm to its full range pos/neg with no binding. Im not sure what you mean by lowering the swash since the elevator control arm link is a solid link w/no adjustment. The problem is at full positive with full forward/back or left/right cyclic the bottom of the hoops (at the webbs where the marking are located that need to face out) catch the corner of the flybar control lever. I didn't get any instructions with my head, just a bag of parts. I'll watch your videos again to see what i missed. Thanks.

Ah OK sorry... I thought you were talking about the Kasama head for the Trx600... I see now your talking about for the raptor. OK... I am still not getting what is hitting though. I checked mine and dont see it hitting.

At full pos pitch, the washout base 2mm below main rotor hub, full forward cyclic, the webb on the front hoop hits the washout control lever where the washout linkage mounts to the arm, next to the set screw. Im not sure how much pitch i should be getting out of the flybar, but with full forward cyclic the flybar paddles are 15 deg or more (maybe to much?).

Just to clarify, the hoop (rear hoop) also hits the washout arm at the same spot w/full back cyclic/full pitch and same with left/right at full pos pitch.

Bob, here are some pic's of my problem.

Well you are right... Just double checked mine. Same thing. But not sure I would worry about it. I have flown mine many 100's of times and I don't see any marks on my hoops from that hitting. Must be because I am never at full pitch and full cyclic. That is a very extreme pitch ruining 12 and 8 = 20 degrees of pitch. So I don't think you will ever be there unless your crashing ;)
Also it doesn't appear to really hurt the loop when it does hit. On mine it just twists the hoop on the balls a little moving the hoop out of the way. Doesn't really FLEX the hoop any.

I wouldn't worry about it. hundreds of people have used this head on Raptors and i never heard of a hoop problem.

Ok, I'll give it a go. Thanks for your input.

Depending on where you got your head from, you might have got some links to some setup tips. I havent had time to watch all of Bob's vids yet, but this link is good for explaining the combos available on setup:

Hey Bob
I receintly installed the Kasama tail assy and blade grips. I do not have the wag that you describe in the videos but, I do have a tick and and it sounds like the tail belt is hitting the boom. I checked to make sure that it is not twisted. The belt is tight and I have even made it tighter to see if that is the noise that I here changes or goes away, no change. I am putting the stock tail case back on with the Kasama grips and see what happens. Any ideas? This is on a Raptor.
Thanks

My wag was becasue the slider was too tight on the shaft. I sanded the shaft down with 600 paper and re-lubed and it was gone.

Okay. I purchased my Kasama head awhile back (fall 2006) and am just now getting 'round to building it. I've followed the videos (much thanks, Bob) and everything went pretty well. I will say that even after heating the grips 180-200 degrees for 15 minutes, I still had to do a fair amount of tapping to get the bearings seated properly in the grips. After inspection, it appears that the bearings are seated correctly -- they match the results in the video.

Okay. So now I have my two grips assembled but not attached the head block yet. What I've noticed is that if I pick up either grip and shake it, I can hear a clicking sound. I can only assume this noise to be caused by the thrust bearings moving slightly inside the grip between the outer radial bearing and the inside of the grip.

Has anyone else noticed this? Is it normal? If it isn't and it turns out something isn't seated correctly, what's the best way to get the bearings out of the grip so I can take another shot at it? Thanks guys.
