  The combination of the Grayson Hobby 3D EPP Sukhoi ARF and our new Shock Absorbing Motor Mount, create the ultimate crash resistant 3D plane! Anyone who flys with EPP, Depon, or Blue Core foamies knows that the biggest breaking point on these planes is the motor mount. The plywood breaks, the glue joint comes off, something has to give in a crash. This plane is perfect for the guys that just like to fly. Builds in an evening using common components and is light and slow enough to fly in the yard! It's the perfect plane to build with your son or daughter who have always wanted learn to fly but are afraid to crash. In fact, crashing is the funniest part with these because they just won't die!

HOW IS IT SO CRASH RESISTANT?
   
 
  - EPP foam bends not breaks.
- The carbon rods distribute the shock.
- The prop saver absorbs minor hits.
- The new shock absorbing motor mount
"gives" instead of breaks.
- It's slow enough and light enough that
the forces from a crash travel all through-
out the plane, are mostly absorbed by
the systems above, and then travel back
down and cause the plane to just bounce!

(See below for what
electronics to get.)
1) I used hotglue for the build and repairs.
2) Slightly nose heavy CG makes it more stable.
3) Shim the motor down and to the right about 3 degrees to counter torque roll.
