Overweight model airplane crashes

This B-29 fully loaded with fuel, smoke oil, and X1 parasite weighs more than the AMA LMA limit of 125lbs. Hot day, high humidity, high density altitude, number 1 engine running bad, and appears to have limited rudder control. This is the 5th or 6th time he crashed one of these, and this time almost takes 10 peoples heads off.

Aero Telemetry's Spruce Goose built for the movie The Aviator

The Spruce Goose flew several times over two days in the Long Beach Harbor. The first test flight took place on the afternoon of Sunday November 23, 2003.
Joe Bok's rendition of the Hughes Flying Boat made its' Hollywood Film debut on November 24, 2003. The airplane was loaded onto a barge and moved into a location near the Queen Mary.  Several vintage Navy boats were moved into a position that would align them with the camera and the model's anticipated flight path.  The Aero Telemetry Spruce Goose made several breath-taking flights that day.




Part of the crew launched and recovered the huge model from a floating barge, while the flight crew were positioned on a vintage World War II US Navy Patrol boat. Academy Award winning visual effects director, Rob Legato, filmed the amazing footage of the Spruce Goose as it passed by the stern of the PT boat to recreate the famous flight of the Spruce Goose.

Aero Telemetry's Hughes H-1 Racer


Great Article as featured in FLY RC MAGAZINE:

AERO TELEMETRY’S HUGHES H-1 RACER      By Tom Atwood



An extraordinary crew works at Aero Telemetry Corporation. Founded by Joe Bok, the Aero Telemetry Corporation (ATC) has been providing airborne electronics and custom built unmanned air vehicle (UAV) systems to the military since the early 1990s. Many of our readers also know that this remarkable company specializes in scale aircraft for movies and in UAV’s. Remember the movie, The Aviator? Joe's team provided 11 different models for the production. Notably, the giant scale Hughes XF-11 (30-foot wingspan), H-4 Hercules (Spruce Goose), and Hughes H-1 Racer were all flown safely and successfully.  As noted at the company's website, these models “are still considered to be some of the largest flyable scale airplanes ever built for use in a movie. Long hours of hard work, perseverance, and technical know-how by the Aero Telemetry team made these extraordinary airplanes possible.”

But many may not know the diverse additional areas of expertise Aero Telemetry has expanded into over the last decade, building on robust project successes in military based UAV programs. One of the coolest projects in aerospace today is the Boeing X-48 Blended Wing Body aircraft or BWB. Aero Telemetry was contracted by The Boeing Company to build the front landing gear for the X-48 blended wing body unmanned air vehicle. “The design and fabrication of the landing gear required the Aero Telemetry team to perform dynamic load testing with data acquisition sensors to match deceleration rates to acceptable airframe load limits.”
            
Aero Telemetry also specializes in vintage engine restorations. Joe Bok and his team took great pride in restoring an Allison V-1710-27 engine. That engine was once a starboard engine mount on a Lockheed P-39 Lightning during WWII. It was shipped back to the United States for overhaul in late 1943. It is an incredible piece of American history that has survived the years to be brought back to life once again by the ATC team—see the projects pages at www.aerotelemetry.com  for more on this and the other diverse programs at ATC. Their technology is also used at academic institutions and in one project, ATC designed a package to detect the impact energy of football helmets, while in use, on the playing field.




H1 RACER
As the AMA planned its 75th anniversary celebration, which will be held in Muncie this July, it inquired with Joe whether ATC might do something special for the gala event. Joe’s team came up with a 50 percent scale H-1 Racer. The H-1 in The Aviator, designed based on countless photos of the original at the Smithsonian, weighed 450 pounds. The new model looked to weigh in at 225 pounds ready to fly. “Too heavy,” said the AMA. It would have to top out at 125 pounds to be legal at the event. Joe’s indefatigable team went back to the drawing board—a 3rd plane had to be designed and built!
 
 And true to form, ATC developed new technology. Precisely engineered resin-infused carbon fiber cloth would comprise the new H-1’s skin. This will be the largest and perhaps the most sophisticated 50 percent scale model in the world, with custom engineered retracts and sophisticated electronic control systems. The 5-cylinder, 4-stroke radial initially envisioned for the project may have to be replaced with a lighter mill. But Joe, an aerospace engineer with a can-do attitude, is not fazed. He says this has been a useful challenge that has expanded ATC’s markets. 

We applaud this magnificent project, and also the contributions of the ATC team in other arenas. Joe and his people are making a difference by providing electronic systems to the military, and for this reason this aerospace group also wears a badge of honor.

Designing the XF-11

Completing the XF-11 airplane in less than 3 months proved to be one of the biggest challenges for the Aero Telemetry team.  Joe and his team had to design, build, and test a custom set of hydraulic, retractable landing gear, fabricate an ultra-strong airframe, coordinate a complex airborne flight control system, and integrate all of these systems seamlessly to overcome the aerodynamic stresses of high speed and heavy payload.

The primary scale models for The Aviator were the Aero Telemetry XF-11 and the H-4 Hercules or Spruce Goose. Both of these airplanes would be designed and fabricated over a period of 3 months by Joe Bok and his Aero Telemetry team. At the time, they were the worlds largest (unmanned) flyable scale aircraft ever flown for a big budget Hollywood movie.

The aerodynamic profile of the wing, engine thrust-lines, CG location, main airfoil angle of attack, incidence angles (between wing and horizontal stabilizer), counter-rotating propellers, and vertical stabilizer offset angles were just a few of the critical design criteria addressed and implemented correctly by the Aero Telemetry engineering design team. All these specific details contributed directly to the success and margin of safety exemplified in all the flights of the Aero Telemetry XF-11.
