This was discussed last year, possibly farther back in this thread; don't remember.

The reason the airplane tends to "stick" on take-off is due to the nearly flat angle of attack caused by the tall tailwheel. With hardly any positive angle of attack on the take-off run you have to coax it off the deck. No big deal, as long as you're aware of it. There were lots of complaints about "jumping jack take-offs" (caused by guys getting alarmed and snatching a lot of up elevator near the end of the runway), but it can be dealt with with.

Another advantage of my lowered tail wheel is I don't see this; the model lifts off as smoothly and gently as a real airplane.
