The next level has been reached with the newly released 90mm Viper Pro II by HSD. With the latest advancements in RC, HSD has infused professional grade components for a well-rounded out of the box experience. HSD has achieved a streamline design on the airframe to reduce drag and boost performance with a powerful 6S 22.2V EDF system that easily breaks the 100 MPH mark. This model features all-metal e-retracts and landing gears, built to high CNC standards for robust quality. An oleo inspired strut design on the landing gears provides dampening shock absorption during touchdown for smooth landings. 12g metal gear servos with built-in anti-lock and anti-stripping features are installed across the entire airframe. To top it off, an LED lighting package including port and starboard lights along with a nose taxi light is included.
The latest version features several new changes. These changes have been made to continue HSD’s promise of a well-designed model. In the latest version, the top air intake has been removed and the fuselage has been adjusted to accommodate the needed performance. Because of this, the HSD 90mm Viper Pro II now has a more aesthetically pleasing appearance. The wing connection adapters have also been improved to increase reliability. Additionally, certain components like the internal horizontal stabilizer spar have been widened to make that specific section robust. Other minor improvements with the e-retracts and steering configuration have also been made to make this a model better than ever before. If you’re thinking about it, take the chance to go go the next level with the HSD 90mm Viper Pro II.
