A couple of planes worth looking at and are top notch are the
Extreme Flight 88" Yak , the
Somenzini 86" Yak and the
AeroWorks 260. They all fit the good power:weight requirement and are great flying planes. Extreme Flight also has a Extra 300 coming out in 50cc size (yellow and blue with DA-50 on cowl). I think by the end of the year. All 4 of them are perfect matches for the DA50.
