F4U corsair mods to make it suitable for carrier landings.

Interesting. A vortex generator works by delaying a stall wheras a
stall strip works be inducing a stall.

Can you tell me what direction your propellor rotates (viewed from the
rear) and what side you have the vortex generator (viewed from rear).

Do you know if the wing section is NACA 5 digit to scale or a special
model type.

Due to their small size airflow over small wings tends to be laminar
over much longer part of its length.

(Hence insect wings are thin and due to testing on too small a models
WW1 fighters were too thin as well)

I should have said a stall strip on the right wing.
The prop turns clockwise when viewed from the rear.
I don't know what the NACA# is, scale wings do not work very well and the
models that have them don't last long.
This model also has the same flap arrangement as the the full scale F4U and
works well.
