Put some extensions on my Durafly Stuka's flaps. Used my Robart pin hinge method. I had to reinforce the area that the pins went in the wing with fiberglass as there was a lot of torsional movement. Credit card material is key as it is flexible enough to let you take the whole thing apart if you need too.
Here are the dive brakes completed. All that is left is reinstall the radio and test fly. Unfortunately, my time this time of year to fly is getting less and less. Might have to wait until mid Jan to get a try.
