The 29" wingspan twin 64 mm EDF rc SR 71 for sale by Huayu Hobby. It is 46 1/2" long and comes as either a RTF or ARF. Weight is about 2 1/2 lbs.
The fastest, highest flying manned jet aircraft ever to take flight, the SR-71 Blackbird aircraft had an outer skin that heated to temperatures in excess of 2,000 degrees F. The effect of this was the strengthening of aircraft components with age.
Huayu Hobby Limited, China, also has a rc SR-71 ARF for sale. Its wingspan is 38" and length is 48". It needs from .46 to .53 two stroke or .65 to .80 four stroke engines turning pusher props for power.
Chris Good's rc SR-71.
The scratch built rc SR-71 Blackbird by Chris Good. It has a length of 91" and a weight of 30 lbs. Power comes from two O.S. 91 VR-DF engines with tuned pipes.
Interestingly the Lockheed SR-71 Blackbird fuselage shape and radar absorbing paint would make it hard to detect on radar were it not for its exhaust. The aircraft was never hit by missiles due to its speed, not stealth capabilities.
JetCom rc SR-71.
The rc SR-71 for sale from JetCom. It has a wingspan of 29 1/2" and a length of 57". For power you should use either a Wren 44 or EDF engine unit.
To better withstand high temperatures, the outer skin of the aircraft was made of titanium. Conventional aircraft usually have aluminum skins.
Flyboy Models rc SR-71.
The rc SR-71 ARF for sale from Fly Boy Models. Wingspan is 38" and length is 47". You will need a .46 two stroke engine for power.
Due to extreme operating temperatures, the Blackbird lacked sealed fuel cells. The aircraft would seep fluids when cold. It would be fueled on the ground just sufficiently to be able to take off, warm up the air frame, and then meet with a refueling air tanker to take on sufficient fuel for its mission.
A rc SR-71 from Wang Dong.
The rc SR-71 from Wang Dong, China. It is a foamy that comes ready to fly, including retracts, twin 4300 kv motors and 64 mm EDF units. Wingspan is 29 1/2", length is 47 1/2" and weight is around 2 lb. 2 oz. This scale model is being sold at numerous retailers who put their name on its box. If you are interested in this rc SR-71 Blackbird, shop around.
The first flight of the Lockheed SR-71 Blackbird was on Dec. 22, 1964. It became operational in March of 1968 and was retired in 1998. On July 27, 1976 it set the still standing speed record of 2,193.167 mph.
Pence Aviation has a giant scale SR-71 for sale. Its wingspan is 56" and length is 107". Construction is all fiberglass. Power comes from twin turbine engines.
Ben Dalstein sent us this email:
"I am very pleased with the SR-71 for sale by Pence Aviation. I feel that it represents an excellent value. It can perform with the best of them, and looks great too. It is not difficult to put together for anyone who has turbine power rc experience. If you want your scale jet flying project to be of excellent quality, unbelievable value, and offer you a finished product that is truly a lot of fun to fly, then you can't go wrong with the Pence rc SR-71."
The SR-71 Blackbird used a special alloy of titanium that could be worked at lower temperatures to reduce costs. Fuel was used for cooling the leading edge of the wings.
StreetJet makes a 21" wingspan single pusher prop rc SR-71 that is for sale.
The shock wave from compression coming off of its nose flowed into the engines, making them more efficient. Movable cones, called "spikes" in front of the engine air inlets directed incoming air at maximized angles to achieve the greatest efficiency. A jack screw controlled by a computer actuated the spikes. A spike could move as much as 26 inches in total.
To reduce the pressures to the engines at high speeds, bleed holes and bypass doors were incorporated. Chines, originally intended to lower the radar signature, were found to significantly increase lift. This aided in maneuverability and slowed landing speeds.
Altecare has a 29 1/2" wingspan, 51" long single EDF rc Lockheed SR-71 for sale.
The unique engines used on the Lockheed SR-71 Blackbird had a two stage design. Turbojet engines, inside of ram jets, enabled the aircraft to fly at slower speeds. The J58 engines could operate continuously on afterburner; the only military engines that were ever designed to do so.
Two 455 cid General Motors engines turning a single shaft were mounted on a cart and used to start the aircraft engines. The noise was deafening. This was eventually changed and the aircraft were later started with a conventional start cart adapted for the J58 engines.
Toysonics appears to have the 29 1/2" wingspan rc SR-71 Blackbird from Wang Dong for sale as a ARF or RTF.
ASARS (Advanced Synthetic Aperture Radar System) were the high-resolution mapping systems used in all Blackbird aircraft.
There is a SR-71 for sale on eBay. We do not see any information about wingspan, length, type of motors, or weight. The only information given is the radio frequency.
A corrugated titanium sheeting was used on the inner portions of the wings. It expands and contracts better than other materials used on conventional aircraft.
There are several mentions in RC Universe of a rc SR-71 from Yellow Aircraft. The model appears to be a pusher prop. However, a check of the Yellow Aircraft site doesn't show it.
The original designation of the Lockheed SR-71 Blackbird was the Lockheed RS-71. That stood for reconnaissance/strike. However, the Air Force brass recommended changing the designation.
Foshan Jun Feng Model Shop, China, appears to be selling the popular rc SR-71 with a 29 1/2" wingspan as a RTF.
A total of 32 of the aircraft were manufactured. Accidents claimed 12 with no lives taken.
Dario from Italy writes about his scratch built rc SR-71 pusher prop radio control airplane:
"My rc SR-71 is all balsa wood and is powered by a Super Tigre G45 2c engine. It is equipped with 7 servos: 1 for nose wheel steering, 1 for both rudders, 1 for throttle, 2 for elevators and 2 for ailerons. The propeller is an APC 10x8 pusher and the landing gear is fixed (at the moment). It will take the first flight next week because I need some other hour for fixing the plastic engine's covers (which simulate the real engines) on the wings. The dimensions of my rc SR-71 are: 1,200 mm length, 900 mm wingspan, and a weight of 2.5 Kg."
