The high performance HK-500GT is 3D flight ready.
99% of parts are compatible with the Align T-rex 500
Much bigger than its smaller 450 brother, the 500GT is an exciting helicopter to see in action and even more exciting to fly. Its 2024 alloy head ensures hard core 3D pilots wont be dissapointed in the performance and the beautifully painted cowl and Titanium anodized components make this a visually stunning helicopter with performance to back it up!
You wont find unecissary or poorly fitting bling alloy components on this heli. Alot of thought has been put into the production of this machine as seen by the FRN* tail which uses alloy only where its needed; in the arms and partially hidden belt pulley making it lighter with no sacrifice in strength; proving the helis no-bling all-performance attitude.
All parts are 100% compatible with T-Rex 500
Included are main and tail blades & Carbon Fiber boom supports.

*FRN Fibre Reinforced Nylon
25% lighter than billet alloy and composed of 30% Carbon and Aramid fibers mixed with Nylon. This provides strength (modulus of elasticity) where standard plastics and 2017 alloys would bend. Check out the all ALLOY CNC Head detail now Click here
