MacAir,

In answer to your question there is no thrust required to the right. In fact there is none to the left. According to the specs on the Hobbico Avistar II ARF sheet on the Tower Hobbie web page there is only supposed to be a -1-1/2 degrees down thrust. If you haven't seen those specs you might want to visit that web site and have a look. It also gives some other valuable preflight checking info.

Good luck!!
