Does anyone know where to add weights to the prop or hub when balancing the V530 prop (original Russian) for tricycle Yak 52?
Engine mounts are replaced. Any other items that should be reviewed before balancing?
Thank you

The key to getting the Russian paddle prop balanced is how close the weight of each blade is when removed from the hub. If the weight is more than a couple of ounces, you will have a bit of difficulty. I would suggest removing the blades and having them weighed on a precision scale to see what the actualweight difference is. Then you will know which side of the hub you will have to add the most weight. (add to the lighter blade side of course). I actually took my blades to the local post office and had them weighed!
Most of the time the hub and blades are static balanced off the airplane. Weight plates made especially for the hub are affixed to the large castellated nuts on the side of the hub with appropriate screws and safety wired once finished.
Before you begin any balancing, it is important to measure the blade length once installed in the hub and positioned close to the proper blade angle or at the center whisker mark on the collar under the counterweight clamp. I measure from the edge of the cuff under the counterweight clamp out to the tip of the blade. They should be within 1/8" or so. Next, be absolutely certain the blade angles are the same to within .1 degree when finished setting the blade angles. Even a very small % of a degree difference will cause vibrations that can not be balanced out.
Lastly, to fine tune the balance, determine the lighter of the two blades and use spray paint on the back side of the blade, putting light coats from about mid-way on the blade out to the tip. After each coat (let it dry first), run the engine and see if the vibration improves. Keep going until it is smooth. Most of the Russian props vibrate the most between 46 and 54%. Some more, some maybe less. So find the point where you feel the most vibration and test at this point after using the "high tech prop balancing spray paint" available only at your local aircraft spray paint supplier, like Autozone aircraft parts or National Aircraft Parts Association (NAPA) or Lowes Yak Parts, etc.  ).

If you have a spinner, its put on the spinner back plate.

Weights on the spinner - this is done during a dynamic balance and does not negate the weights on the sides of the hub. Weights on the hub itself can be added on the large castellated nuts to static balance the prop and hub regardless of whether there is a spinner on the airplane.
