I need help with my Burdov WinStar F1B. The problem I am experiencing is that the DPR prop hub is distorting under a fully wound motor. This was occurring from day one but when I was trimming and learning to launch a DPR model. I was using older rubber that didn’t have as much poop as the newer stuff so the blades stayed feathered, so it was not a problem. Now with newer rubber and the hub locked I can put the blades in the feathered position and everything looks great. BUT when I unlock the hub, move the wire in the “L” slot to the DPR flight position, one of the prop hangers will no longer stay feathered and the other blade is barley on the hub lobe.
I’m dumb founded on this one. I disassembled the front end several times and don’t see anything wrong but then I am far from being an expert on this. Does anyone have any suggestions besides buying a new front end?
I have some excellent before and after close up pictures but naturally the pixel count is too high and I haven’t figured out how to attach them yet. I would be more than happy to email the jpegs to you….like they say, a picture is worth a 1,000 words.
A fellow flier resized one of my photos so I could post a picture...it's nice to know there are people willing to help others that sometime are computer challenged.
