Britbrat,

It is true that I did not need them. It is also true that until I removed them, the plane would not fly properly and one of the problems was that it would climb unless excessive down elevator was applied. The other was that it would not fly in a straight line. I do not see any problem with the spin devices if the plane flys properly, however in the beginning of this post Jeckelbro stated that he had the same type of condition. As these parts are only taped on, it would be easy, with the help of an experienced pilot, to remove them and see if it helps this problem. If it does not, they can be easily replaced.

The conclusion that we came to on mine was that they were not installed quite the same on both sides causing different amounts of lift and a "crab" to one side. When adjustments were made to correct this, it caused the plane to climb.
