We do improvement and upgrades to KDS Innova series helicopters. The quality and performance have been significantly improved compared with the original product according to our efforts.
First of all, there is a great change on the part of main rotor head. It adopts the popular structure, Direct Flight Control. This special design makes 3D aerobatics flight more flexible and the speed faster.
Second, the material of tail gear was changed to fully aluminum alloy material. It is more unbreakable and impact resistance.
All KDS canopies are hand-painted, and we also provide various kinds of hand-painted canopies for some commonly used designs on sale.
Third, the main shaft bearing block was designed with the fixed form of lower, middle and upper decks. This upgrade help eliminate vibration when helicopter doing high speed rotating.
The forth is that there is adding a fixed plate to both sides of carbon fiber frame, which improves its strength. We find that the frame is well protected and only has little damage when crash happens from testing experience
Fifth, we make a thicker, 25mm tail boom. The thicker tail boom reduces the transmission of tail unit resonance to the frame, and it also help provide more stable flight.
The carbon fiber board structure of tail unit is more simple and easy maintenance.
Innova 550 helicopter is a transition upgrade model for whom has flight experience of 450-size helicopters and wants to improve skills. Due to the low cost and simple maintenance, the helicopter is very popular with pilots all over the world.
The helicopter is provided with necessary electronics, such as Motor, ESC, Servo, UBEC, KDS FBL System etc..
KDS FBL System was developed with MEMS technology. The matching with N690 digital servo makes the tail rudder of your helicopter has perfect locking control performance. The helicopter has great spin control effect, and is much more flexible as well. You can adjust the model based on personal preference.
KDS BL5052-1200HV brushless motor provides a great power, and let all pilots with different flying skill levels have chance enjoy violence flight.
We provide the helicopter with three metal gear digital servos N680. The servo features high speed (0.11sec) and big torque (12kg) and was designed for bigger size R/C helicopters.
The flight weight of Innova 550 helicopter is very light, and the load current is only around 70 A. It seems that the equipped brushless ESC 120A HV is “big Marathi car”. But we don't have to worry about that the ESC will be over-current protection and lead to out of control due to the excessive current of motor.
One 6S 3300MAH lithium battery can provide a steady flow of power for Innova 550 helicopter, and greatly reduce the cost of the flight.
