SR-71 Blackbird display model

  • Sale
  • Regular price $6,399.00


This is the SR-71 static display model based on our World Class scale RC model!

The Ultimate Jets SR-71 is not just the only large Blackbird commercially available on the market. It is also one of the best scale model of its generation!

This models won at Top Gun 2018 in Master class and a achiveed second place at Top Gun 2017 in Expert class including a stratospheric static scoring of 99.125  as well as "critics choice" and engineering awards! 

 

 

 

The airframe is built in-house by our team of very skilled aero technicians. It uses a proprietary layup and production technique that we have used extensively on our UAVs.

The building technique and materials used are one big step forward compared to the techniques popular among the current JWM winners and has never been used in the model industry.

Technology:

Our CloudTech laminate technology uses the highest modulus carbon fiber strand available on the planet from Torayca. This strand is the exact same one used by Boeing on the 787 and is 100% made at their USA factory.

It is laid up in a series of uni directional layers oriented according to CAD computations. The UD fabric is made specifically to our order and is 0.3 mm thick.

The core material is a specific ultra light weight aerospace grade PEI foam ( used in the future B-777X ) that is thermo formed to the plane shape at 300 c and is certified to sustain 120 c continuous without de-gassing. This foam is 3 times lighter than the Airex grade used on the best models being currently sold to the hobby market but features the same resistance to compression.The skin created using these materials is infused in one step with a very specific resin gel sheet technique. A super high modulus epoxy resin is used and post cured for 48 hours at high temperature, offering a resistance of 120 c continuous. The laminate is 100% carbon fiber from Torayca.

Architecture:

The plane internal structure was designed and specced using finite analysis simulation to offer 10 g resistance with 280 N total thrust. The internal structure is CNC cut and 100% made of Airex/ carbon fiber laminate with the same gel sheet epoxy resin as the skin and post cured in one step with the remaining of the structure. The wing and fin tubes are also aero grade carbon fiber made and post cured in the same step with the structure to fuse the glue joints with the spar/ ribs. This is a unique process allowing both the skin and the internal structure to cure together and fuse with the epoxy joints, creating a virtually monocoque shell

 

The plane is 100% made from carbon fiber/ PEI/ glass fiber.

 

Optional fixed Landing gear:

The optional fixed  landing gear was CAD drawn by Oli and is using our now famous hybrid 3D printing/ machining process.




The struts are completely in-house CNC machined on our Siemens milling centers to 5/100 mm precision. We are using 100% USA produced and certified Al 2024 T351 rated at 47,000 PSI yield strength and Al 7075 T651 rated at 73,000 PSI for all the gear components.

The hyper scale landing gear covers are laser 3D printed to 25 micron resolution and can be replaced in case of damage.

 

 

The tires are 3D printed in a very scale light grey high abrasion resistant rubber. They are hollow but not inflated. A 3D graphene internal structure insures the stiffness of the tire. This technique allows to save an amazing amount of weight on the landing gear.

The plane can also be ordered without the fixed landing gear, to be dislayed gear up on a pole

 

Plane transport:

The plane splits in 6 parts: the nose section, the rear fuselage, the wings and 2 fins.

The bulkiest part ( rear fuselage ) is 47 in/ 1.2 meter wide and 78 in/ 2 meter long when dismantled.

We ship the kit in a bespoke 47" x 78" x 20" plywood crate that can be re-used for international transport. This crate can be dismantled for storage and is fumigated.

An 80 in wide trailer or pickup truck is recommended for transport.
