Anyone have a Koll Rotor Pro?

I just got one and I have some questions about setting it up. There is an instruction manual that came with it, but the pictures are very dark and almost impossible to see. Plus, the manual explains the balancing process, but does not give directions on where the 8 machine screws go that came with the balancer.....Help I see that there are 8 threaded holes in the base of the pivot cradle so I am assuming that this is where they will go....

I just wanted to know what to do with the 8 machine screws, nut and washer that came with the balancer. I see the threaded holes in the base, but what are the screws used for? Is there something that they are supposed to hold in place? The only thing that came with my balancer is the long rod for supporting the blades, and a small bag of 8 machine screws, 1 washer,1 nut and a bubble level. Like I said, the manual that came with mine was made on a copy machine and it is so dark that I can't make out anything in the pictures.

the screws arenot used all at once....
they are for different sized blades.
one of them i thik is for balancing fans, it´s the one with the funny shape and some tubing.
the bubble level goes next to the calibration nut on a small recess.
here´s my first run at photoshop... no laughs please.....

anything else?

Nitro crusher ..I will take some pics of balancing some woodies and send them to you if you like .. It will take me awhile though ... I had the same problem when I got mine too .. I did see a web site somewhere ( I cant remember where though ..I had to reformat since then and lost it ) ..Maybe someone out there will remember where it was ..It showed step by step with pics on using it ..

pepito9,

Thanks for the picture
That looks great. I will print that out for a reference.

crash1953,

That would be great if you could get a couple digital pics of the balancer as it is set up during the balancing of main rotor blades and/or TR blades. Just e-mail them to me when you get a chance

Hi Dirt Dummy!!

Have you had your Raptor out this year yet?

No problem. I sure appreciate the help

As oaksmith mentioned, it might be a good idea to post the pics here rather than e-mail them to me. There may be others who are having the same trouble that I am.


Thanks again

ok here it is the pics

here you go.
first balance the koll on it´s own with nothing attached use the balancing screw for this. a little hint, look at the koll, i´ve glued some 500 sandpaper to add some footing for the blades. also you might want to add a little grease to the balancing screw, this will help you by making the nut a little harder to move on it´s own.

1. since i don´t have a precision balnce i use the koll to find the heavy blade. i will use the heavy blade for setup and all corrections on the light blade. the havy blade is on the right of the picture (see the bubble level)

2. now this is the setup for finding the heavy blade cg

3. the cg has been found, without moving the blade you can mark it from the bottom of the koll through the big hole in the middle.

4. here is the metal rod used as a guide, after the first blde cg has been found, tighten the nut holding the rod (lightly), remove the blade and place the light blade in the same position.

5. the light blade in position, the bubble level shows that we need to add weight to the tip to get the same cg location. the tip is to the left in this picture.

now i go back and put the original blade in place to make sure nothing has moved. the i add weight to the light blade on the balancer until the cg´s match.

the procedure for chordwise balancing is about the same, only the setup changes, here it is:
look at the screws that will act as a guide, the leading edge goes against these screws.

here´s the blade in position:

when this is done i place both blades on the koll, and see how the weight has changed, and add weight on the cg of the light blade to get them the same. remember always start with a balanced koll on it´s own.
remember the weight at this stage has to be added at the chorwise and length wise cg so you don´t change any of the previous adjustments.

the same applies for TR blades, only in a smaller scale and using the smaller screws.

don´t tighten the screws to much, the koll is made of aluminum and you could strip the threads.

hope this helps, if you need anything else just yell.
