My wife has an Aresti 40 with a Saito 72 in it. I test flew it for her a couple of weeks ago. About halfway through the flight the engine quit. I landed deadstick no problem. We tore it down and found the tank was split. Anyone else having tank problems with this bird. My wife had the same problem with her UltraStik 40 with a Saito 56. The Aresti seemed to fly well the 4 or 5 minutes I flew it. Much like a pattern ship. Not a 3D type airplane, but might work for beginning IMAC type work.
