FOD problem

Benovitch · Oct 30, 2009, 11:55 AM

Hi,

Is there anyone that uses some kind of FOD screen on their EDF planes to prevent damage to the rotor, something like they use on the turbine engines.

Too restrictive, Ben.

Touhgt so, next time when I go flying I take my vacuum cleaner with me to clean the field

Kinda obvious, but you can limit damage to the rotor by having zero throttle when and if you belly land. Only takes one small stone to hit the rotor when it is under power to break a blade. When you pick the model up, hold it nose up and then nose down to let any debris fall out so you don't damage the rotor next time you fly.

I make it a point to look into the ducts and shake and blow into the outlets too. (We have a rough grass field).

I use a window screen wire mesh to cover the huge cheater on my J-10. Ive blown two rotors due to a gravel piece getting kicked up by the nose wheel before putting the screen on. Sometimes its just a necessity.

I kill the power altogether before touchdown. Haven't lost a rotor yet.

I have had grass clippings stall the rotor. Sometimes it is neccessary to carry a little power for a successful/safe landing. With no brake being used, the fan could still be turning on touch down. So as Kelberts pointed out, it is a good practice to check the ducting for FOD. A stalled fan is a good way to ruin a ESC or just trigger the overload shut down. Either one completely avoidable with good preflight practices.
