Near crash --- has this happened to you ?
[8D]
Was training a new flier on his Alpha ARF . Sometime into the third flight of the day he began to have a steering problem . Being on a buddybox , I took control and found I could not get the Alpha to turn left . After a lot of rudder and aileron input I was able to land the plane . Upon checking the plane over he found the colored trim on the right wing was loose . It was held in place on the inboard end by the rubber bands and on the outboard end by the Alpha decal . The air flowing over the right wing was interrupted by the trim that had turned 90 degrees causing a partial stall of the right wing . ( almost like a spoiler ) We removed all the trim on both wings as we found some more that were becoming loose . The plane flew great . Wondering if this is a common problem or if anyone else has ever heard of this . If this plane had crashed we probably would never have found what caused the loss of steerage .
