You're right Jim, the entire premise of this model was for it to be dead stable, and bearly responsive. Jerry Brach was a club member of the Michigan Radio Control Society ith the sixties when he designed it for his son to learn on. Funny, he wanted royalties but the best Carl would come up with was his picture on the box. Don't know what ever became of him, the club disanded when the Farmington Hobby Shop went out of business.
