Hello,

I have been racking my head over this since I purchased my "Topflite" Prop Balancer.

Now when I use the balancer as the instructions state, I place the cones so that the narrow ends point towards the hub and eachother (Left Photo). However, the cones touch and do not securely hold the prop in place (not enough clearance between the two).

Ok... Below I have posted three pictures displaying three different combinations of installing the prop on the balancer using the cones provided.

Each combination has a different effect, meaning the prop balances totally different on each setup.

I read somewhere on RCU that props have a "precision" hole (smaller hole I believe) and a "non-precision hole)

In this case, the "precision" hole is on the left in all pictures.

Considering that all results vary greatly, what combination is the correct combination to use?
