This design along with my A6 intruder should be in the elite series if I had one. They print perfectly, are fun and easy to assemble and fly great on the first throw. The Vampire has always been known to be an easy to fly platform due to the very light wing loading. It has great stability due to the twin tail booms. Its easy to hand launch due to the easy to hold exhaust. The vampire will plop pillow land at almost zero airspeed.

Assembly tips. Only tricky aspect of the build is running the elevator servo wire through the left side tail boom. BEFORE gluing the left side tail boom parts, run the servo wire with NO extension through the L horizontal tail hole, then you fish that wire through the back side of tail boom 3. You then send the extension wire through the front of tail boom 3 and connect both and tape them together. then resume assembly. Here is a video :
Pre flight info. The only thing you should be aware of is the elevator has alot of pitch authority. I would run the elevator at 80% rate and 20% expo to be safe. be away you can easily overcontrol the airplane with pitch if you pull too hard.
Full rate on the ailerons is good.
