Hi Jorge
Warp drive props are a bit hit and miss. I have tried 5 different new ones, all of which were not acceptable, until I finally found one set of blades that all had the same amount of twist/washout. I made a simple gauge to check the blade twist.
I'm not sure how they are made but there always seemed to be two blades the same, and one with a different amount of twist. I wanted a nickel leading edge prop, but gave up after three attempts and settled for a standard one.
It meant that it was impossible to set up the blades properly, and no matter what you did you would always have some vibration at a certain RPM.
The prop that I have now has the same amount of twist in each blade, the individual blades are 5 grams difference in weight , but when built and set the prop is perfectly balanced, within 0.1 grams, and it tracks within 1-2 mm :-)
Before you do anything, try a different prop, maybe borrow one to try.
This is after you have checked you carb balance and engine mounts first.
Cheers Mark
