Myasishchev M-101T Gzhel
Meant as air taxi aircraft for the vast Russian territory, Myasishchev made the M-101T Gzhel. It is somewhat modelled after the SOCATA TBM series, and even looks like it. Like the TBM the M-101T is a single engine turboprop aircraft, with the engine mounted in the nose. It also a single air intake below the prop spinner and rectangular cabin windows (more high than wide). The cockpit side windows are only slightly different. The horizontal stabiliser is placed below the vertical stabiliser and the nose gear doors are small. Not many were built, hence there is only one version.
Confusion possible with
The TBM series appear to have been the model for the M-101T. However, the TBM has a somewhat more pointed nose and longer nose gear doors than the M-101T. Also the horizontal stabiliser is placed further aft on the TBM.
Piper PA-46 Malibu Meridian
The PA-46 Malibu Meridian (currently M500/M600) is Pipers entry in the single turboprop class. It can be distinguished from the similar Myasishchev Gzhel mainly by the larger, rectangular cabin windows (wider than high), but also by the air intake(s).
This single engine turboprop has big winglets, two large exhausts under the nose and a higher placed stabilo. That should be enough to avoid a mix-up with the M-101T.
The Ae270 looks a bit like a stretched TBM-700 with winglets. Thus it also has a resemblance with the Gzhel. It is a bit bigger, has winglets and six cockpit windows (instead of four).
The Epic LT has two very characteristic curved cockpit windows and (nearly) round cabin windows. Also notice the nicely curved leading edge of the vertical stabiliser.
The Farnborough F1 (a.k.a. Kesterl JP10 and One Aviation K-350) is very similar to the Epic LT. Both have two very characteristic curved cockpit windows and (nearly) round cabin windows.
When you put a single turboprop in the nose of a Cessna 402 you immediately get a look-al-like. However, the tip tanks, cockpit window and tail are still clearly original to the Cessna, and as such key feature for recognition. (photo Kevin Cleynhens)
