HD Helicopters of Germany known for their premium HD500 helicopter will be releasing their latest model, a competition grade 750-size model that can swing up to 766mm main blades and 126mm tail blades. This new HD750 benefits from the same level of uncompromising precision and thoughtful engineering that exemplified their HD500. From a full, real carbon fiber frame and tail boom to 7075 aluminum, the airframe is built to be extremely strong, rigid, and lightweight. The canopy is constructed of hand laid fiberglass into a streamlined shape. The on-purpose exaggerated belt powertrain is designed to handle the massive power that 800-size motors can output without skipping or stripping.
Likewise to the HD500, the HD750’s low vibration powertrain, oversize gearing and versatile main rotor damper system supports a wide range of motors, blades and head speeds. Beta testers flew the model down to 1250 RPM before tail performance started to degrade and all the way up to 2250 for outrageous air shredding performance. Thanks to the versatility of the airframe, you just pick the motor KV, blade type and batteries (up to 14s) for your desired flying style.
The airframe is receptive to all manner of outrunner motors for 700-800+ size models running on 12s to 14s LiPo packs. One of the prototype testers even sport flew the model on 7s for 6 minutes. The HD750 was engineered for the ultimate in flight performance adaptability.
For $1600 you’ll receive a hand-built model by the staff of Superstition Hobbies out of Queen Creek, Arizona.
