Erdel

I buy a kit and the other plane on the picture is an ultimate with 90 four stroke
About the engine , I agree (de acuerdo) Acroman because i ask some friends and they said OS 90 have problems of power[&:], in Chile YS 110 is so $$$$$$$$$$$$$$$ but i know its very very strongers, think the power of YS on 3.4 Kg of Epsilon ,,,,, wwwooooouuuuu,,,,,,,SSUUUUPPPEEERRRR MMMMAAAAANNNNN IIIITTTSSS CCOOMMIINNGG
I don´t think like Acroman abuot WB is better, you have to see Epsilon on your hands and look the difference.

Acromann, you write spanish better than me write english.

Erdel tengo otro kit de Epsilon por armar en la bodega, si quieres fotos de alguna parte en especial dime y le saco fotos.
