F-8E Crusader 1/7 scale

 

 

 

 

 

 

 

 

 

 

This is the first 1/7 scale fully featured jet powered F-8E Crusader available on the market.

 

The plane has been CAD designed and CNC cut from the original Vought Aircraft blueprints.

 

The airframe is built from our GlassTech processes. It uses a proprietary technology that allows us to fuse the epoxy glue  joints to the shells at the closure of the molds.

The fuselage is made from monolithic glass/ carbon fiber with the highest quality aircraft certified Finnish birch plywood available on the market.

 

All the flying surfaces are made from Airex/ glass fiber/ carbon fiber laminates.

The wings internals are full carbon fiber.

 

 

This plane has been the object of a thorough scale design. the fuselage is engraved with all the panel lines and panel joiners rivets ( both flush and protruding types ). But it also features ( and this is an industry first ) all the intermediate stiffeners and stiffeners flush rivets. When looking at the skin at a shallow angle, the waving pattern of the stiffeners and skin wrinkles are subtle, but apparent.

 

 

The optional landing gear is ultra scale and features many laser 3D printed parts with a 50 micron resolution. It is 100% cut in-house on our Siemens machines from Alcoa USA certified Al 6061 T6. 

 

The wing is in 3 parts.

The center section incorporates the tilting mechanism ( operated with 2 servos or screw jacks ). Two Al 2024 large tubes are dimensioned to support high G loads. It also includes the operational inboard flaps.

The two outer panel include an integral leading edge slat and the outboard flaps. Both are operated by standard size servo. The slats can be deactivated and glued in retracted position for people looking for simplicity. Both flight controls are live hinged.

The stabilizer shaft position and stiffness have been extensively studied and optimized for strength. The stabilizer tube is a certified 1/2" Al 2024 unit turned down to 11.994 mm. It is supported by two very large ABEC 5 needle bearings of 14 mm wide. 

 

 

The entire plane was the object of a thorough CFD study and optimization. The wing airfoil is a modified Michel Selig S6063, optimized for the required Reynolds numbers and for the use of leading edge slats.

The stabilizer configuration and airfoil combination was specifically very carefully optimized to avoid tip stall at the high angle of attack required when the wing is tilted up at slow speed with flaps extended.

 

 The plane is currently in the test flight phase and we will take pre-order as soon as we have finalized the kit.

Ultra scale landing gear, pneumatic.

Ultra scale landing gear, electric.

Ultra scale cockpit
