Hi All:
Today I wrote to Mookie for the same questions I posted here, and he reply with the following:
"I think I had pictures on my thread for the front wheel door. It's a spring hinge that holds it open then a wire pulls it closed with the gear. I left the rear hatches off for cooling of batteries( also I read they were a real pain to finish). Use a proportional servo for the flaps so you can control the movement. Mine are all standard size. Good luck, send photos."
So I understand perfectly. I´m going to put all standard maybe hitec or futaba. and low profile aileron servos for the flaps. I hope the flaps come down with enough torque.
I´ll keep you posted, and photos are comming.
