Got a KDS 450s, similar to trex 450se v2, but the swash set up is reversed. The antirotation bracket is in the front with the single servo and the 2 servos are in the back. Have it in a MD500 fuse and this would look great on it. Does anybody know if it would work on that setup?

Hi HK, any chance on getting the 3 blade head? I want to fit it on one of my Artech Hughes 300-400 machines, I think with "scale" blades it will look great and fly great...

3 Blade is really difficult to fly, thats why we dont make it.

Hi Guy's
Just mounted this head on a Hk450. I find that i don't have enough tail authority to fly the machine. I've spent day's messing with throttle and pitch curves to achieve the lowest torque, but i still am holding full right tail in a hover. I've tried bigger tail blades and still no deal. Any idea's??
|

| |

I have a feeling the torque may have something to do with the rotor-blades you use. I used wide-cord blades first and then got some norrow (scale) cord blades and found there was definatly a difference. You can get these blades on the internet, from Hong Kong.

It's pretty easy to setup. With everything on the heli, make sure that the blade grip is 90 degrees behind the associated ball on the swash, and that the height of the anti-rotation bracket gives sufficient travel. This works well for me! YMMV.

5 blades is great for MD500 Hughes500E* If I spend up on a $150 Flybarless plus the head $27,and multiblade tail - a scale machine, I would prefer a 3 blade scale ship like the Lama, AS350 Squirrel and AS355 Twin Squirrel or even the EC135. My question - Anybody who bought one of these been able to get the track and balance of all 5 blades really smooooooth? Are we talking a very accurate scale and careful use of the pitch gauge???

Assuming the hub is true, it's easy. Color each blade differently, but at the same distance. I used nitto denko electrical tape. Make sure all blades are the same mass! Get a flashlight and hold the machine firmly in your hand with the blades spinning. Shine the light carefully on the LE of all the blades, and adjust so none of the colors 'stick out'. It's smooth after that, as long as the hardware itself is running true. If you have a lathe you can bend the main shaft to take out any wobble in the physical hardware. I didn't use a pitch gauge at all for the tracking. Make sure the hardware runs true (without blades) before doing the tracking. Main shaft and hub must be perfectly true.

Yes, you can get multiblade heads extremely smooth. If the hardware itself (here, really just the hub component) is true and straight and all the holes are in the right place, even CF blades will track-up dare I say better than a 2 blade sustem. Be sure that opposing blades are all the same mass. Be sure also, that in a 5 blade system, pretty much every blade has to be same mass, as there are no opposing blades. My TR450 doesn't vibrate whatsoever with my 4 blade head. Sill sorting out the 5 blade hub.

I found out if you are going to put this head on a HK450 pro you will need to use the longer antirotation ball from the swashplate that came with the hk450 pro kit.
|
|
|
| |
|
sleat

The picture is wrong. Both the inner and the outer bracket go _around_ the main shaft. Imagine a D within another D. The plastic anti-rotation link is nearly vertical, and has plenty of travel in this, proper configuration, and does not bind with any of the PC links at any reasonable angle. You are right, if the clevis (outer D) is swung round outside, you'll need to connect it far away from the swash. But the clevis and clamp should nest, like babushka dolls, and almost appear as one unit.

You can see the back order quantities if you place the item in one of your wishlists, and then look at the wishlist. When I placed my order, there were 214 on back order. Last week the number dropped by 100 when they got the first shipment. At present there are 118 on backorder. Note, you cannot see it in the "All wishlist", you need to look at the individual wish list (ie, 1,2,3,4 or 5.)

Why are the static swash plate balls not in line with the dynamic swash plate balls? Won't this be a problem?
|
|
|
| |
|
jeremymtc
(80%)
By "not in line", are you referring to angular alignment in terms of rotation, or are you referring to radial alignment ("vertical alignment")?
In the first case, angular "misalignment" is normal for a multi-rotor head set up for flight purely mechanically (ie* non electronically stabilised). The relative positioning of the upper pivots vs. the lower pivot is dictated by blade phasing and the positioning of the swash follower.
In the second case, I suspect that it is done in order to apply greater mechanical advantage to rotate the blade grips. Most multi-rotor heads are built this same way.

|
|
|
Was this the best answer? YES | NO
|

Or, maybe I misunderstood you, and you are referring instead to the "extra" ball pivot between the normal control rod balls... This is the link for the swash follower. The control rod pivots are still standard 120*

Ah, now I understand what you were getting at. My RC Aerodyne 5-bladed head is just like this HK unit - the "dynamic" or rotating portion of the swash has the balls placed inboard of the "fixed" pivots for the control rods. I think that this is done to make the head/grip movement a little less "lively".

No. In a CCPM system, there are three links from the servos, one which is anti-rotation. The swash tilts in 3D space and moves up and down in any combination. The dynamic swash plate must have PC link balls at the same relative position to the blades they control, with 1 to 1 correspondence. In addition, another ball is included for the anti-rotation (should be called pro-rotation?) link on the dynamic swashplate. Each ball leads the blade it controls by 90 degrees of blade-sweep, so the blades on the right and left of the chopper moves when the swash tips fore and aft.

Today’s blades are fairly close just make simple adjustments with tape (different colours if possible for tracking).Get all blades with same center of gravity then take the heaviest one & adjust the others till their all the same .Personally I would use white blades & clear tape then use white board markers for tracking. Slight differences will be less pronounced on a 5 blade system then a two blade system & the blades can be used to compensate
