This is my third year flying, and my first year at 3D. I have a UCanDo 46 with a Magnum 70 four stroke, and a 14x4 APC prop, with Omega 15% fuel. I have about two gallons of fuel throug the motor, so I would consider it broken in. I have the high speed needle adjusted with a Tach exactly as per the instructions - about 200 rpm below (richer) than peak rpm. *Note: I do not have my engine inverted as the airframe design calls for, I mounted mine upright (see photo).

The engine has been running fine, except for the last three times out I have dead sticked. The motor seems fine and then about 5 or 6 minutes into the flying it just quits. I checked everything, fuel filters, different fuel, glow plug, high speed needle, fuel clunk seems freely moving, not out of fuel etc. Everything seemed ok. And then I started to realize that I had been doing a lot of hovering the last few flights, and I remember that the last dead stick was right after hovering... I decided to do a flight without hovering, and I made it through the whole flight (about 10 minutes) without a dead stick.

My question: Does hovering contribute to dead sticks? Is that a known problem with 3D?
