Ok, I get what you are saying, but what I am talking about is different props with different diameter and pitch, which of course give me different levels of performance, not to mention a high rpm timing and compression compared to a low timing and compression ratio...
If I am running a cf prop, then I can only try new timings and new head spacing, but I am talking about making props that have different levels of performance, some are good in the turns, accelerate good and reach top speed half way down the straight away...
Then the next up is a prop that accelerates a little less, but is a few miles an hour faster and reaches top speed at 3/4 of the way down the staright... Then I have another prop, it accelerates even slower, but reaches a top speed 2mph faster than both previous props, but does not reach this until right when its time to turn... I was hoping you would have some theory behind this and what prop would be ideal for our course.... I now realize I should not be discussing this on an open forum and there by giving away all my prop secrets!!!
Thats funny.... I cannot even make a prop that goes as good as the V-2 cf prop, oh wait out of 15 props I made, 1 was about as good, I better get to it, I broke that one, if I make 30 more at 2.5 hours a piece, I will have 1 or 2 as good as a 7.50 cf prop!!!
Wow, even at 10.00hr thats 750.00 bucks for 2 props... 35.00 bucks does not sound so bad now!!! Whats Delponto's number???
