I recently bought a IV-1200 speedster with the 80hp 912ul/GSC tech 3 blade prop, all around 1999 vintage, first flight 2001. The TTAF/engine/prop is about 80hrs, but now I see that GSC says to replace prop after 5yrs(bummer). From what I can tell from reading on this forum, the IVO props seem to be most popular, but are there other suggestions? It would seem that the cost to replace the GSC blades is not that much less than a new IVO ground adjustable (and easier ground adjustment) or am I missing something? Is there any specific problems with the IVO? I can't see how GSC can keep selling props that have to be replaced after 5 yrs if competitors don't have those kind of limitations? Also, I would like a "skull cap" type spinner, so is the IVO ground adjustable and/or the in-flight adjustable compatable with these spinners and if so is there a particular spinner/supplier recomended? I realize this is a lot of info to ask for, but one of the first things I did was order a Hegar 5" spinner for the GSC, only to find out that the GSC hub does not have a hole in the "center" and the back plate of the spinner has a 1" diameter protrusion on the back side. While I could make the necessary modifications to make it work, as stated earlier, it appears I need a new prop anyway which is why I looking for as much info as I can get.    Thanks to everyone for posting so much valuable information... by the way my name is Paul Perry ,I live in Southeast Missouri and frequently fly over to the Kentucky Dam Airport. I mention this because a saw a post mentioning this airport as a good choice for a fly-in ( I agree!)

Hi Paul

 I had the three blade GSC on my Kitfox 5 912UL when I bought it. It did a good job and I really like the way they look with the wood prop. I replaced it with the IVO and it performs about the same or slightly better. I only have the small scull cap on the IVO. If you get the IFA option for the ground adjustable IVO you can really get much better results. Better climb out and much better cruise speeds and fuel savings. Still miss the looks of the GSC.
