Okay, a few things. 1st, the Stryker is not, I repeat, is not a trainer or a plane for an outright beginner.
Delta style wings are difficult for a newbie to control.
2nd, the Stryker has a 480 motor for power. To really scare you out of your underwear, dump in a brushless
motor like an AXI or Hacker.
3rd, for repairs on foam, use either epoxy, CA (like super glue) for foam or, Elmer's Probond.
The Probond will actually fill in gaps in the foam while it cures.
My Stryker has about 100 flights on it. I run 8 cell nimh's in mine. Wrecked it once. I hit a pine tree coming out of
a double roll at full throttle. The motor mount cracked the foam where it attaches. I used probond to fix. Aint had
a problemo since. I am going brushless in it next year.
