NV is not sensitive at all , again I do not have one but have friends who have the PA 75
and said that it was pickey on NV setting ( they had pipe Expert pilot )and have since gone to Brett Buck RO Jett 61 and like it better as
they said that it was much more user friendly. PLEASE don't start a pissing match over these statements about the PA. This is what I have seen with my own eyes and ears. I know Dave Fitz PA 75 runs very steady and is very impressive .
Hi Walter,
That is great news about the K77, I am very very happy to hear that the stunt world has yet another choice. Kaz is a great guy, and I am sure he will be great to do business with.
I concur, that we don't want to start a pissing match over your, or your friends, PA75 statements, yet, I would like to at least add some clarity to their statements for others that will read this thread, since I, and several others never had the issue with a "picky needle" on our PA75's. Since I run one personally, box stock, recommended quiet pipe, recommended prop, etc, I know that they can run just dandy when used as directed. If anything, my needle is so broad that I am too conservative in my adjustments and have been known to not turn it far enough during big weather DA swings.
The one time I saw a PA75 go off to the races, like your K77 is currently doing, is when someone tried to put a small 12" 3 blade (a typical PA 40 or 51 prop) onto a PA75 to see what it would do.
An abundance of power needs to be harnessed somehow, and that is usually done with diameter, under camber, or de-tuning the engine with small venturi, changing rpm range on the pipe and pitch on the prop, etc etc.
Personally, I would find it hard to blame the engine if I buy a super powerful 75 and expect it to run like a 40 without a substantial adjustment to the setup.
Once again, congrats on the K77, it sounds like it will be great once you get it adjusted, and I am glad you will have more patience with it than your friends did with their 75's.
I look forward to hear more once you get it where you want it, and what your final setup on it will be.
Thanks again for sharing,
EricV
