Great flying plane... I set my CG at 90mm originally but it was a little tail heavy for my liking so I added .5 ounces to the firewall and seems real good now..
Works fine without the struts... They are easy to use though.. I bolted mine on at the fuselage and never take them off.. When I take the wing off I just swing them back and tie them to the fuselage.. On the wing I instilled !QUOT!trailer hitch!QUOT! ball joints so the struts just pop on and off there... Very quick and simple... Doesn't take more then a couple minuets to do at the field and I like the look of the struts.
