Learning to Fly




Guys,

Is it necessary for a plane in a tractor config to have landing wheels? I mean if the wheels are not there, then how does one take care so that the prop does not break each time the planes comes in for landing? No matter what the size, if the prop remains parallel to the wing then it will not hit the ground, but if the prop stops perpendicular to the wing, then it is sure to hit the ground if the wheels are not there. Since I cannot control the position when the motor will stop spinning, then how does one do belly landings?

Second part of the problem is how the folding prop helps in this case.

regards
Pankaj

High spirits we have: gravity we flout.



Mostly people use prop saver in this scenario. On a prop save the prop slips out of the shaft instead of breaking.

Bellylanding a tractor?


In case of a folding prop, the blades of the prop just fold away when you turn the throttle off. You have to set the esc brakes On for it to work properly though. If the esc brakes are not on the prop keeps free wheeling after you turn the throttle off; in this case also most probably the prop wont break. I've never broken a folder either with esc brakes on or off. But a free wheeling prop will cause lots of drag that's for sure.
