HIROBO Freya - Sceadu - Shuttle > Radius block alignment - The easier way

Hello guys.
when playing with my X-spec on the ground today i noticed that right \ left cyclic would induce a little fore \ aft cyclic too (visible on the paddles), and its not from the servo, meaning the Radius block was out of alignment.

anyway i came up with this simple method. just turn your radio on, and turn the slide block by hand until you get to the sweet spot and see that the cyclics dont mix at all and tighten the block down, its that simple !

Enjoy !

Hi Lior,

I thought that the only correct position for the slide block is the position when your washout arm is perpendicular to the flybar, if we would look at it from the top of the rotor.
Isn't it the most correct way of working of mechanics?

i just thought i would share my easy method for radius block alignment
ok i put the blades back in the holder and looking down from the front of the machine i twisted the head till the flybar was in alignment with the boom that puts the head at a perfect 90 degree then with the blade holder holding the head loosen the block and adjust till the 8 balls on the swash are in alignment then tighten that is as mechanically straight as it can get thats just my theory im no expert but i have 0 mixing and it flys sweet allthough i dont fly like i3dm im trying like hell!!!

by the way i got your vid on my pc thats bad azzzzz first you did the pyro loop then a back flip then the coolest move i have ever seen it was like a hard banking turn while piro chaos havent a clue what to call it but it was just simply killer !!!!! chet

Chet, first of all thanks a lot for your compliments. im very glad you like my vid.
second, i founf that the method you mentioned is easy enough, but not 100% accurate sometimes, my method can give you a second look on the alignment to make sure its perfect though.

carcrasher about my X-spec vid, its here:
http://www.runryder.com/helicopter/t104029p1/

Enjoy ! i know i did !

PS - Chet, if you wana tell me at what point in time in that vid that move was made ill try to find it and explain it for you guys.

Chet, Ok i see you meant the edited version thats located here:
http://www.runryder.com/helicopter/p769679/

anyway that manuver is similar to the sudden stop but while piroing. i fly fast backwards and then initiate a hard "down" elevator pull right into a chaos and the machine would fly through while chaosing because of its former speed.
you have good taste, this is probably my favorite 3D move !!

not to burst your bubble or anything like that but if you read you
assembly book it tells you where to set your timing if im talking about the same thing as you are
thanks jeff

thank's jeff this post was for a easier way so i doubt if your bursting any bubbles.

try this do it the way the book tells you if its your first time building one it will take you 10 mins to decipher what your reading and 1 min to do the job

then try it my way and you tell me what you think is easier!!!! chet

I3DM -- This tip should be one of those that never finds it's way to the bottom of the posting list.

I tried it on my Freya, EVO, and two Caliber 30's. It's QUICK, SIMPLE, and ACCURATE. It sure beats having to stand over the heli, and try to keep the flybar over the tailboom while trying to line up the swashplate balls! Thanks for taking the time to post it.

Maybe i'm missing something here,but don't
you still have to line the flybar or bladegrips up with "something" even with I3DM's method,it doesn't just adjust/check itself with no point of reference
If you don't ,there will still be paddle interaction seen even when the radius block is spot on,because that's what the mixer base unit does.

You got it wrong dude.
if the radius block is not spot on, the final result would be paddle interaction.
it works both ways, since the final result is whats important ! whats why you can just align it by the paddles. i found all of my machines to be slightly off, and they fly better now !

try it - you'll see what i mean. no reference point needed at all !

SteepCurve.

Try it first.

It's much much easier to simply set the heli on my workbench, line up the flybar with the tail boom (something that can be done easily with the heli at waist level), then simply move the "elevator" stick through it's motions and watch the flybar paddles.

Much easier than it is to stand above the heli, try to keep the flybar lined up with the tail boom, sight around all the stuff in the way (head, radius block, washout assy, linkages) -- and then make a good determination that the inner swash balls are lined up with the outer swash balls.

I3DM's method also tells you how much and which direction you need to move the radius block. I set up four helis last night in about 15 mintues.

Go ahead and continue to do this adjustment however you wish -- frankly I3DM's method is so easy, I can't understand why anyone would ever want to do it any other way after having tried this method.

I also tried this method, but I did line up the swash balls and then moved the elevator up and down while looking for paddle movement. It worked great for me.

Brian, it would work even if the swash balls arent lined just as good.
