REFLECTOR: Flying MT prop with bad brushes

[Andrew Judge]

That's the answer I was looking for! I just confirmed with MT and they stated the same. It would eventually go back to feather.

They also stated that there is now a high-temp block that does not melt as easily. The cost of a standard block is 260 and I understand a high-temp is about 450. Anyone have experience with the high-temp?

Andy, I don't have any direct experience flying with a bad brush block, but I did have to return from Denver to SE Minnesota with a bad motor once. My advice - Don't Do It!

What happened to me was that over time, usually 30 min. or so, the prop would drift from where it was set towards full feather... and my RPM would get higher and higher... and my temps would start to climb... and I'd have to land and reset. It took all day to make what should have been a 3-4 hour flight, and I don't think it was particularly safe.

My two cents...

REFLECTOR: MT elcoprop - burned out pickup - fly?

I've got my second burned out brush block after about 230 hours on it. It's stuck in a fixed position. I was wondering if anyone has flown one fixed like this until they were able to get a new brush block. Seems to be ok flying. Attached is the picture of it at 5000 and I got a static of 2580. I've got to get to MA...
