Hubsan H202F FPV Invader Co-Axial 4CH RC Helicopter with 2.4Ghz Radio System RTF

About the Hubsan H202F "Invader" Helicopter

Hubsan has two helicopters that has the same "Invader" canopy, one is Hubsan H102F and the other is Hubsan H202F, what's the difference? The Hubsan H102F "Invader" "Invader" is a Co-Axial Helicopter, the difference is H102F is made for Experienced flyer, H202F is made for First Time flyer. Both have the professional like "Invader" white canopy, made with quite thick plastic, this gives extra durability, we crashed on grass for a few times, the aluminum frame and this thick canopy are still intact!

What is Co-Axial Rotor System?

There are one Upper rotor and one Lower rotor, they spin in the opposite direction at the same speed to counter the rotation force and heli will stay pointing at same direction. To change Heli diection, it simply changes one of the rotor's speed, and heli will make a turn. And there is a distintive Flybar on top of the rotors, it is a thin metal rod with a weight block at the end, so when it spins, it will generate a rotation force to level the helicopter, it act as a flywheel, it helps a lot to stabilize the helicopter. Thanks to the two rotors and this heavy flybar, Co-Axial Helicopters are great for first time flyers.
