RE: Flutter
G'day
My friend was recently flying his new Balsa USA Student Trainer when it suddenly started to make flutter noises. Friends of his told him to land NOW as they could see the elevator fluttering madly.
He managed a pretty normal landing on half an elevator.
On inspection he found that the join between the two halves of the elevator had failed and also that part of the built up horizontal stabiliser had also suffered damage. Did the flutter cause the damage? Did the failure of the joiner cause the flutter? We are not sure but I think the model would have been better built with either a more substantial joiner or one servo for each elevator half. They are quite large.
