In 1946 the company experimented with a motorglider conversion of the 1-19. This was attempted because the company had acquired a used
Andover engine that produced 12 horsepower (9 kW) at 4000 rpm. A 1-19 was modified by bolting the engine in pusher configuration over the wing/fuselage junction.

Once the war had ended the availability of cheap military surplus gliders severely limited the market for sales of new gliders. By the summer of 1948 it was obvious that the boom was not going to occur and this left manufacturers with surplus inventory of powered light aircraft and, in the case of

During one flight
Schweizer test pilot Frank Hurtt was able to find a thermal at ten feet and climbed the aircraft up to 2,000 feet (610 m). Other than one flight where the aircraft was auto-towed with the engine running at full throttle, this was the only time that the altitude achieved

Construction of the constant chord 1-19 wing was of wood and fabric. It utilized a two spar, double strutted design. The fuselage and tail were made from welded tube covered with aircraft fabric. The 1-19 was originally produced with an open cockpit, but in service most were modified with the

With production of the SGS 2-8 and SGS 2-12 military training gliders complete in 1944, Schweizer
Aircraft did studies of a series of utility and sailplane designs, trying to determine what would best suit the post-war market. Design studies conducted in this period included:
265:. The additional wingspan brought the glide ratio up to 18.5:1 from the 1-19's 16:1. A single factory-built 1-20 was completed, NX-91840. Two additional 1-20's were created by private owners who converted their 1-19 by replacing their stock wings with the longer wing.
185:
Many economic forecasts had predicted a post war aviation boom, with thousands of military trained airmen returning home to the US to fly civil aircraft. Like many aircraft manufacturers
Schweizer planned to produce new aircraft for the boom.
363:
Distance flying in the 1-19 is challenging, given its 16:1 glide ratio and red-line speed limit of just 75 mph (122 km/h). Jim Hard flew an SGU 1-19 190 miles (308 km) to qualify for a Gold distance and
Diamond goal flight.

Schweizer quickly identified a need for a version of the 1-19 with better performance and designed a new set of wings for it. The new aircraft, with an additional seven feet of span, was designated the

The 1-20 was never certified in the US and these aircraft are flown there as experimental aircraft. The SGU 1-20 was issued
Canadian type certificate G-53 1960-10-27 in the name of Cu Nim Gliding Club of Calgary.

addition of canopies. The 1-19 is very light, with an empty weight of just 320 lb (150 kg), but it is complex to assemble and disassemble as this requires use of many small pins.

The resulting aircraft displayed disappointing performance. The combination of the low-performance 1-19 and the low-power engine left the aircraft unable to climb out of

In May 2008 there were still 25 SGU 1-19s registered in the USA along with one 1-19A and three 1-20s, the factory prototype (serial number 1), and two converted 1-19s.
812:
334:
SGU 1-19s assembled from factory kits were accepted as certified aircraft and were designated as SGU 1-19A. They were otherwise identical to the 1-19.
354:
The 1-20 is the long winged version of the 1-19. One 1-20 was completed and a number of 1-19s were converted to 1-20s by installing longer wings.

The 1-19 first flew in 1944 and was quickly ordered by
Schweizer's 15 US dealers in large numbers for use as a trainer. Fifty were completed.
