Well, besides the problems with faulty sensors, one thing is for sure. If anyone mistakenly times the engine in the proper counter clockwise direction at the incorrect 46 degrees, they have a problem. The timing will be way too advanced both at starting rpms and at speed. It will definitely try to "bite" you upon starting, and the engine could be seriously damaged during use. Seems like Tower Hobbies has left themselves open to serious liability concerns with those improper instructions. Look at all the confusion just in this one forum and imagine how many people truly have been affected.....
