Xlpower Specter v2 latest model from Xlpower.
Rotor head lowered by 10mm compared to the Specter V1, the helicopter benefits from improved vertical mass distribution and agility. Like its predecessor, the Specter V2 rotor head consists of double row angular contact bearing rotor head for incomparable bearing life and smooth operation. The Specter V2 also does away with tailboom supports and instead opts for a with 32mm diameter tail boom for a cleaner look and extremely rigid design. the third shaft bearing support arrangement has been simplified, making rotor head installation and removal much easier and faster.The battery tray design has been completely revamped. It loads from the rear, effectively removing the need to remove the canopy to install the LiPo pack. An optional upgrade offers a built in connector in the tray, so when you insert the battery the helicopter powers up and there no need to remove the canopy between flights.The gyro tray has been moved to the front, making wiring easier and cleaner, and reducing vibration transfer to the gyro. The Specter V2 also has a wider and lower landing gear which helps reduce tipovers during autorotations and rough landings.The Specter V2 comes default with a wide 8mm custom tail belt with extreme long life. In addition, the size of the tail belt pulleys has been increased, from 80T/16-17T to 100T/20-21T, which significantly reduces bending radius of the belt improving belt life and reducing belt drag and power loss, which can especially be noticed during autorotations.The V2 comes with the same durable 15mm thick main gear as the V1 airframe, and can optionally be upgraded to an ultra heavy duty 18mm gear for a nearly indestructible power train.One of the more noticeable changes on the Specter V2 is the tail control rod, which has been moved to the top of the tail boom. This allows the tail servo to be mounted as high as possible, once again improving on the vertical Center of Gravity. It is mounted directly opposite the center cyclic servo, offering a clean symmetrical look.Like the Specter V1, the V2 has a simple one piece billet aluminum tail box. The design has been optimized for easy assembly, quick maintenance and low part count. A new super lightweight tail fin also helps reduce unneeded weight. The Specter V2 comes stock with a 21T rear pulley offering a 4.76:1 ratio, and can be upgraded to a 20T pulley for even better tail performance for low head speed flight . Because of the larger pulleys, the tooth contact on the belt is higher which greatly reduces the chance of tail belt slip on extreme tail loads and reversals.
