To express it simply:
Modern profiles create a bubble because the max thickness is put way to the
leading edge in order to increase the laminar flow length on the lower
surface, and turbulators help to destroy this bubble. Earlier profiles are
designed differently and don't tend to have this bubble, so a turbulator is
completely useless (at best).

I just bought a DG-101 and was trying to figure out if turbulator tape
would help the performance.

I sent that question to the general DG factory email account
) and got a nice reply from Wilhelm Dirks (Chief
Designer!).

His response was succinct; "Turbulators won't make sense on the
profiles used." Nuf said...but I wonder why.

Thanks, John
