Any Aerodynamicists here?

[Jim H]

Good morning , a long shot I appreciate.

I’m looking for any advice relating to aviation aero. Ok, it regards a model Radio Controlled aircraft, however the fundamentals surely apply.

I had a huge crash with one of my RC aircraft this week, and I believe the source could be flutter associated with the design.

Basically the elevator servo failed, resulting in total loss of pitch. However, I consider it to be an aero imbalance in the design, which resulted in the failure of the servo.

Rather than single component failure and poor installation off.

I’m trying to understand horizontal stabiliser (tail plane) positioning relative to the trailing edge of the wing axis.

TIA

I believe in real life control surface flutter is addressed by weights or dampers.

Good afternoon Simpo. I do hope all is well with you?

I originally posted this in the Scale Models section.
I’m a member on the RCM&E forum where I posted, about this very issue.

Some very informative posts there, which are kinda supportive of my suspicion..

You never know? Adrian Newey might have a look over this forum ( anyone got his WhatsApp)?

I mean? Dafter things have happened ..
