The ASK 13 is probably the best and simplest glider to operate effectively
as a twoseat trainer. not necassarily the best for prepping pilots to fly
slippery glass single seaters. However it does exactly what it says on the
tin and if, you can fly a K13 well and accurately then you can prpobably
fly most other gliders too that the potential pilot will progress to
next.



About the only thing keeping the ASK-7 and -13's from being the best
trainers for the money is that their cockpits were not designed for the
"modern" physique.
