I have a Parkzone FW-190 that I have been flying for the last 1 1/2 months. Everything has been working great with it. The last landing I did went without notice, except when I picked up the plane and started running down the motor to drain the battery. I noticed that the motor was running but the propeller wasn't producing any thrust. The propeller would spin at a relatively low rpm. I replaced the battery with a fresh one, and still had the same problem. I opened up the cowling and did not see any damage to the gearbox and nothing was loose, broken or bent. The only difference I found was that when I would turn the prop before this occurred, there would be some slight resistance in its movement. Now the prop spins very freely at the slightest touch. I can only guess that something has happened to some internal component of the motor. Does anyone have any ideas on this?

Thanks,

Chris

I might be wrong, but how you have explained it seems as if the prop has come loose and just needs re-tightening ?
Have you checked that ?

If it isn't the prop it is the black cog attached to the motor which has let go eg spur gear has done its motor attachment. You need to order a new cog. This a fairly common problem with the Parkzone P51 and FW190 in stock setup. Have a look at the FW190 and P51 threads on the Park and backyard flyers area (heaps of posts and info!) http://www.rcuniverse.com/forum/forumid_148/tt.htm

The P51 thread has about 2000 posts so you will need to sift through it but there have been many attempts/solutions from loctite to metal gears etc.
