Lanxiang SR-71 Blackbird EDF RTF 2.4ghz RC
The Lockheed SR-71 is an advanced, long range, Mach 3 strategic reconnaissance aircraft developed from the Lockheed A-12 and YF-12A aircraft by the Lockheed Skunk Works as a Black project. The SR-71 was unofficially named the Blackbird, and called the Habu by its crews, referring to an Okinawan species of pit viper Clarence "Kelly" Johnson was responsible for many of the design's innovative concepts.
A defensive feature of the aircraft was its high speed and operating altitude, whereby, if a surface-to-air missile launch were detected, standard evasive action was simply to accelerate. The SR-71 line was in service from 1964 to 1998, with 12 of the 32 aircraft being destroyed in accidents, though none were lost to enemy action. Since 1976, it has held the world record for the fastest air breathing manned aircraft a record previously held by the YF-12.

Guy Glover - Tuesday, 27 July 2010Big box arrived vey quick and on opening, all the parts were present and correct. One or two minor 'dings' on the foam but no problem, the components
are few but nicely made. Throw supplied glue away and use epoxy on the 3 main glue joints (front fuse and 2 fins). It was worth spending a bit of time
making sure the front fuselage fits well and don't forget to put the wires through before mixing the glue. Build dead easy and all of 20 mins. Manual
pretty useless but does give C of G and 3 degrees of reflex on elevons and a selection of pictures. There again it is pretty straight forward. No
control throws mentioned which is a pain. All supplied radio fitted easily and the electrics worked fine, everything nicely labelled. It is worth
spending a bit of effort tweaking the U/C - nothing wrong with it but a bit of care makes it work better. I have fitted a servo speed reducer to make
the retracts work in a more scale like way. 4S battery supplied with basic charger with no power supply. Use a proper charger anyway and bin the
supplied one. Plane fully assembled looks great and any marks are easily hidden with matt black paint (Humbrol) applied with a bit of sponge rather
than a brush.rnI only had one major gripe with the SR-71 however which I hope was limited to my model as it could be seriously dangerous. The servo
arm splines were not a good fit on the servos in the wings which caused the elevons to slip when under load. I ended up cutting the servos out to fit
arms which were a proper fit on the servo splines and then re-gluing the servos back in. This was quite annoying and took twice as long as the rest of
the build.rnrnNow it is together it looks superb and the noise it makes is just brilliant. Not flown it yet but it should be quite an interesting
experience and a real conversation piece at the field.rnCan only give it 3 out of 5 stars because of the trouble I had with the servo arm splines but
I would have given it more........
