Hara Springs Measured
After sitting on my desk for a year - I finally got around to measuring the Hara Springs. I measured two springs and took an average.
I'm impressed - these spring actually measure very close to the rating on the package - that's rare in the RC world.
The graphs show that the springs are completely linear (with best fit R squared value between 0.9988 and 1.0000 for you technical types).
The measurement was done with a Chatillon 10 lb load cell and a test stand with accuracy within .001".
published = 12.88, measured = 12.97
published = 14.00, measured = 14.37
published = 15.12, measured = 15.44
published = 16.24, measured = 16.41
published = 17.36, measured = 17.57
I used to be a spitter, now I'm a swallower. I graduated.
