    Since large Depron is harder to find, what is the best method for converting or using smaller sheet foam...like 20"x30" $store foam when the plans call for sheets of 27"x39" foam? (SU-35v5 plans for ex.) Beginner scratching head...
    1. Use more foam and glue together forming larger sheets?
    2. Butting sheets together and creating largeer sheets only for certain parts?
    3. Shrink the plans by a percentage to fit?

    As I tend to build "larger" planes these days I've found joining sheets together to be about the best way to do it.

    I try and place the joins on a part that is either not structural or can be re-enforced easily (or is already across a carbon spar or similar) but usually once the glue has dried (my current favourite is Gorilla Glue for joining) it's pretty strong anyway.

  3. Also cut the plans up and place them where ever you need to on your sheets of foam. If the part is to big by itself do as Sterling101 said

    Reinforce joints with dry wall tape / glue or thin packing tape ( never use heavy duck tape ) weight is your enemy, the less park jets weigh, the better they fly usually
