My Aresti 40 was purchased way back in 2001, powered by a YS63 turning a 12 X 7 APC. Assembled model per instruction manual. No problems. Airplane was used to compete in Sportsman Pattern. One suggestion, provided Hangar 9 hasn't already strengthened/modified the two piece landing gear in the current model, is to either add an aluminum plate over the existing gear parts before affixing gear with screws to fuselage bottom or ditching the two piece gear legs entirely and opting for a single piece fixed gear. Due to aerodynamics of the Aresti, it lands fast. Some landings can be harder than others. Avoid full stall landings and running off the runway. In conclusion, the two piece gear will eventually pull away from the fuselage. So do yourself a favor and correct the problem before it occurs. The old saying "if it ain't broke, don't fix it" don't apply here.
