Two (2) Replacement Main Rotors for Mini Infrared Remote Control Electric Helicopters

I bought this as a replacement for a Yiboo mini Euro Tiger Airsquire, which broke one of the connecting arms between the main rotor and stabilizing bar. These new rotors have a slightly different stabilizer - it has more of a wing profile than the original type. I wasn't sure if they would work but for $4 what is there to lose?
Once fitted, the helicopter flies a lot a better than it ever did before! It is much more stable and doesn't veer off into the wall when attempting to take off (which is what broke my original rotor). Some reviewers here said that their models would not fly any more because of the weight of the new rotors, but the Yiboo is OK.

No instructions came with the new rotors so here's what worked for me (For the Yiboo anyway). Getting the old rotor off is not easy! If the old rotor will not simply pull off:
Cut across the plastic shaft of the old rotor just below the stabilizer bar, and above the tell tale hole with wire cutters or similar. You...Read more

The rotor blades look fine. However, when I installed them on my son's helicopter, the helicopter wouldn't get off the ground. It's spinning in the right direction, and it is close to lifting off, but just not quite. The new blade doesn't look any heavier than the original, but both are so light that it is hard to tell. Maybe weight combined with a little different lift angle on the blade is just enough to prevent it from flying.

This is the correct part if you have a PicooZ/Air Hog Havoc 2-ch heli.
Make sure that the rotor fits snugly, because a loose fit will not provide adequate lift to get your heli up and running even though the rotors seem to spin . You also have to adjust trim and make sure that the tail rotor is clean of wrapped hair or fuzz, and perfectly perpendicular to the main rotor- these are essential for proper functioning of the heli, and typically have to be checked/adjusted after each crash.

This replacement is definitely sturdier than the original rotor, as well as the single spare that came with the original heli.

This product has restored my little heli to full function and made me a happy little child again, much to my wife's chagrin.
