Hey Marvin,
Got some ideas for the fowler flaps. I have a set of the C-130 Plans that was designed by Skip Mast. I looked at the flap slides for that
airplane. In fact i found my pictures when i built the flaps for my Quality Fiberglass C-130 and Im sure they will work on the ASM C-130 with some modifications . i got spare wings for the ASM C-130 so i just might give it a try. tried to upload some pics but having problems. Also i noticed on your main gear your using the stock spring. I modified mine with brackets i got from Troy. they work excellent with no bending and the gear doors are closed with small springs. Ill try again later to upload pics.

Jerry.
