    Could you please explain?

      I used the "zip tie mod" on my 1700mm FMS P-51D. It was sorta a dog, especially at 6000' MSL where I flew out of. What they recommended was take a small section maybe an inch or less long of a zip tie. Then you put the zip tie lengthwise on the prop hub where you will lay the prop down to screw it onto the prop hub. You put the zip tie underneath the forward (leading) edge of the prop. This essentially rotates the prop just a bit to give it a bit more pitch, or bite into the air for more power.

      I think it might have worked although I never ran a gun on it to see the difference in speed with the zip ties under each blade.

      You can try it to see if it does any good. It didn't hurt anything when I tried it.

      • The blade root on the FMS is flat so you could do that. The spit has a round root so you can’t. Maybe drill the bolt holes and alignment pin hole angled? In wouldn’t because it may weaken it.

        • Hey guys, I wasn't sure about the Spitfire, but all my stock FMS props have the zip tie mod, at 5000 feet, it made a difference at least to me. I have also used it on the Freewing P51D with good results. When I took some of the planes to Muncie, WOW, at close to sea level, there was a big improvement in performance, mind you I didn't fly them without the zip tie mod there so it may have just been the altitude.
          Have to take a look at the spare prop I have for my Spits and see if there's something that could be done.

          • So here's a little tip that I almost learned the hard way. A few weeks ago, one of the retracts on the new Spitty popped out as I'm sure most of us have experienced. So as not to have it happen again, I used E 6000 glue which several of the guys here have used. I reassembled and didn't think anything of it. Turns out that E 6000 can seep out from under as it dries. It glued the retract to the wing and I had a heck of a time getting it loose. Finally managed and peeled off the 'rubber like' glue from the retract case. Got into the case and sure enough there's another blob of 'rubber' on the bottom of the circuit board, 'gumming up ' the travel of the the retract trunion. Popped the stupid thing out and reassembled the retract, tried it out and it works fine. If I have a retract pop out again, the whole darned thing stays apart for a few days so I don't have this happen again. Yes, it was in the air, but stuck in to down position. After landing I goofed around with it and it finally stuck in the up position, but it labored something awful to get there, and there she stayed. Thank God it was on the ground and not in the air, bellying in a Spitty anywhere on our field would not be an enjoyable experience.
            BTW, post # 6800, wow, didn't know I had that much to say!
