IVO InFlight Adjustable

[av8rps]

I'm glad to hear of success with the 70 inch. I think that just might be the best compromise overall. However, as stated, if I had a 72 inch I'd try that before cutting it down.

When I had to cut my blades down (due to water erosion when I tried the plastic prop-guard) I measured as accurate as I could, and then when done I weighed them with a really accurate scale, which told me I had to sand some off one blade yet (not even measurable however). My new cut down blades run really smooth doing it that way. So that would be my recommendation if you decide to cut your blades down later.

It's ironic how different we all operate our planes that are so similar, but apparently yet so different. I commonly will fly my 912ul around under 5,000 rpm, as it operates so smooth in the 4600-5000 range. And with full pitch and only 4800 rpm I easily cruise around at 105 mph with still probably an inch and a half of throttle available (and remember, I'm on 230 lb amphib floats). At 5200-5400 I feel like the engine is not as smooth. Oh, and for anyone wondering, I have verified both my ASI accuracy multiple times, as well as my tachometer accuracy. So these are real numbers.

I would love to see how my plane would do with an IVO prop and a big bore 912 putting out 110+ hp. I think that would be really SWEEEET!!

Has anyone out there flown a model 4 with the 100 hp 912 and the IVO IFA? If so I'm curious what performance you are seeing.
