A training glider, manufactured on a constructive-technological basis of the Aviatika-MAI-890 aircraft. The Aviatika-MAI-890 parts and units make up more than 90% of all the glider parts and units. Its basic difference is that the glider has a wing aspect ratio, increased in comparison with the aircraft and simpler design of the chassis. The glider is adapted to towage by the Aviatika-MAI-890 aircraft. With the glider appearance it is possible to speak about the organization of a «club triad»: a single-seater training aircraft and the towing Aviatika-MAI-890 in one, two-seater training Aviatika-MAI-890U aircraft and the training Aviatika-MAI-920 glider.
