Hi Guys,
OK here is the update. I put on the new head button with the Nelson plug and it works great. 6 Flights and it was still good. Tachs up just about the same, but it puts out more smoke in the exhast. Looks great going by. Another strange thing is the needle is much easier to adjust with this head/plug combination. No idea if it was any faster or not, no radar gun to play with today. I can tell you one thing, I reall can't see wanting to go that much faster. OK maybe 200 just a couple of times
By the way, I am going back to the CF APC prop. The Taipan prop satrted to show a white area half way out in the blade. I did not like that at all.
