Flew the other day. Took off from a gravel road. It is very dry here and thus the ground, particularily a gravel road is very dusty. When I took off and landed I noticed a lot of dust. When I got home and was givinng the bird a close examination for cracks etc, I noticed a film of dust covered the bird. I also noticed that when I manually spun the motors there was a slight catching/grinding sensation. I beleive this fine dust got inbetween the contacts in the motor. I gave the bird a slightly damp wipe down and I blew strongly directly into the motors. This seemed to get the grit out of the motors.  Anyway just thought I would post, to perhaps have other avoid these conditons.

Always best to hand catch for this exact reason. When you feel up for the challenge you can also hand launch.

I agree you probably had some grit in the motors. There are no contacts aka brushes in the motors though. Clearances are pretty tight and i can see how sand could cause noise/binding. I have a small square of plywood i use if i am going to take off and land in dirty areas.

For cleaning dust off the Phantom and from the motors, I would used compressed air they use for cleaning electronics.    In addition, as Rigworker states, use a 2'x2' piece of...well...anything really (cardboard, plywood, floor panels, etc) to launch and land your bird.

Since I hike in the mountains with my P3, I carry in my backpack a rolled-up rubber mat.  Works great for dust-free take-offs and landings.

the one we use for work is always in the padlock.  I now use auto take off and hold it well above the ground  its a great way to launch... no dust..   and catch it on auto landing, as soon as it stops descending it shuts down in your hand.  very easy to do

After having experienced flips on auto-take off and even arming, not sure I'd be too keen to hand launch.

It that sucker flips those blades could do some damage if they hit you in the face and eyes.

I launch all the time in dusty, sandy areas but that rubber mat idea sounds like a winner!

How thick is your rubber mat and where did you purchase it?

I made a Heli-Pad out of Plexi-glass and carriage bolts.  This might help too!

thanks for the suggestions everyone.  i would prefer to stay away from the hand catch/take off method. I cut the tendon in my finger with a chisel years ago and am paying the price. rather not risk another injury, plus i am using carbon blades !!!! the plywood is good idea but when hiking into remote locations, carrying that extra stuff is not practicable. the rubber mat sounds good,  or just off my phantom backpack, but I still think given  how dry it is, dust would likely still fly.

From Home Depot - $6.97 a roll - 48 in. x 20 in. Black Ultra Grip Drawer/Shelf Liner.  I also cut a large piece for the backpack to lay down on to keep it outta the dirt, which you can see rolled up on the side of the backpack below.  The landing pad piece is folded inside the backpack.

I launch off my backpack case if it looks too dusty.
