I've been flying the Stratos I got on eBay, used, a lot. Lately it has had some problems making right turns. Not as responsive. Yesterday it was just not as responsive turning in any direction. It seems that the differential thrust feature has stopped working. So, this morning after a difficult flight in wind that the plane would once have handled well, I made a few modifications, by increasing the elevator area to the max (there is provision for this, cutting through two little patches and using tape to make one large elevator) and increasing control movements on both elevator and rudder by relocating the clevis locations in the control horns. I still have rudder/elevator mixing. When I've got less wind, I'll see how it flies with these mods. It'll be more like a conventional rudder, elevator, throttle airplane. I have no idea why the differential thrust stopped working. It seems to have failed in one channel first, and then in the other channel. I've been storing this plane in the garage and it got really hot this summer. Could the electronics be heat-sensitive? I never store my lipos in the garage. That would be asking for trouble.
