Same as the old one. 90-120. The 2 meter one will be suitable for the 140 size motors. The two prototypes are flying with YS 160's. As for the smaller 120 model changes. Main change is that the wing sits higher on the fuselage and control surfaces are stiffer. The rest of the changes are cosmetic or for practicality.
Having flown the prototype of the boys I can say I am really impressed how such few changes improved the flying of what was an already good flying model. The boys is set up a lot more tail heavy than I have mine and it is capable of some seriously hardcore 3d while still being manageable to fly (Takes me some getting used to) But good fun. Scheme looks good in the air also. Underside is very simple and bold so it stands out well in any sky.
