kindly give me links for reinforcing nose of skysurfer for protecting  while crash landing

give me links of same

and practical suggestion

kp

Maybe, you could try Fiber-Glassing the nose using epoxy?
If you choose to fiberglassify your nose, do fiberglass some part of the fuselage so even if you crash, you won't obliterate the aft fuselage as the strong nose will transfer the loads of the crash aft.
But that will increase the aircraft weight and the crash impact...

Edit: last line

Careful you will end up with diminishing returns if you make the aircraft heavier, it is designed to fly at a weight and more likely to crash anyway if you make it heavier. All aircraft would be made of concrete if strength was the only factor

Gary is 100% spot on. Increase the weight, increase the crash impact

Further, the material of the fuse is fairly resilient, and is designed to absorb some impact

Better just fly it as is, and focus on improving your flying skills. These models are easy to repair too!
