Which speed mods do you have?

Aileron & flap seals
stabilator seals
flap track fairings
wing root fairing
landing gear/brake assembly fairing
wingtips with landing lights

There is definitely some speed increase, which is nice. However, in
my opinion the best value(s) are the wingtip landing lights followed
by the improved pitch/roll authority with the aileron and stabilator
seals.
