Gosh, It’s A Gobosh

With a name derived from the phrase, “Go big or stay home,” the Polish Gobosh is an LSA with attitude

goboshIf there was ever any question regarding the viability of the LSA market, Cirrus and Cessna pretty much erased those concerns with announcements of their own LSAs at AirVenture 2007. Both companies obviously hope to lure new pilots to their step-up models.

The Gobosh is offered in three varieties. The top-of-the-line Elite Plus features the Garmin 496 GPSMAP (below, right) and GTX 327 transponder, PS Engineering PM-3000 Stereo Intercom and Beyerdynamic HS 300 headsets.
The Gobosh sits low on the ramp, with a swept tail, spiffily spatted wheel pants, a signature mackerel-mouth air scoop beneath the cowling and a semi-bubble canopy for maximum visibility in every direction except straight down. Regardless of how it does in the sales race, there’s little question the G700S is an aesthetic winner.

Pilot and passenger climb over the sidewall and reside abeam the main wing spar, the most stable position and prime location directly above the normal CG. The canopy hinges at the front and folds down to enclose pilot and passenger in a roof of Plexiglas.

Performance is about what we’ve come to expect from LSAs. Climb runs between 750 and 850 fpm from sea-level, standard airports. Level at 7,500 feet, the Gobosh offers about 116 knots max cruise. Fuel burn at 75% with the 100 hp Rotax out front is just under 4 gph, so you can reasonably plan to range out 3.5 hours before you’ll need to stop for fuel. That should allow a radius of operation of 400 nm at max cruise. Service ceiling is 13,200 feet.

The Gobosh climbs between 750 and 850 fpm and reaches a 116-knot cruise speed at 7,500 feet. Fuel burn at 75% is nearly 4 gph, allowing for a 3.5-hour range.
Almost by definition, LSAs are committed to better short-field performance than normal-category airplanes. The type has been employed on private grass and turf strips in Europe for two decades. Gentlemen farmers and owners of wineries and country homes in the UK and on the Continent often clear away the brush and use personal aircraft as private transport from their back door to major terminals.

Handling is light and fun, with pitch by far the most sensitive control axis. Roll rate is good, but not nearly as quick as the elevator. This is a rudder airplane, so you’ll need to keep your feet moving during maneuvers to avoid embarrassing yourself as I did.

With a 39-knot dirty stall speed, the Gobosh sports predictably excellent short-field performance. Stalls are no-brainers with no tendency to roll off on a wing, so you can make approaches as slow as 55 knots without tempting fate. If you accidentally decel into a stall during approach, the plane recovers with a slight reduction of back pressure and a little power.

Perhaps surprisingly, the airplane can jump off in just over half the runway required for landing. That’s exactly the opposite of most aircraft, STOL or not, that can land in a short distance but require more runway for takeoff.
