I bought 3 sets of these for each servo on my 150. They were easy to install, but you do need to leave the plastic ring out of the servo casing. You could file it thinner if you still want to use it, but is is too thick to use with these gears and the hole is not big enough for the servo horn mount to go through it. Just leave it out. The servo did feel a bit more authoritative after installing the gears, but I did not notice a difference in performance. I really purchased it for durability, and have yet to challenge that with a crash yet.

I installed this gears to my servo and... it doesn't work. After some researches I find out that the reason is shaft is too big for white ring and it makes too much friction that servo can't overcome. And servo gets stucked. You can see that spot on image:

Don't buy this product. Waste of money. Shame for hobbyking engineers making such a stupid mistake.

Works perfect! Well done. It flies the same way as with the plastic gears. I advice put some grease among the teeth.
