Hey guys, I was kicking around using a parallel valve io 360 with whirlwind prop. The 360 with higher compression Pistons would get me to about 195hp based on a few engine builders I have talked to at snf. The advantage is 25plus pounds lighter then the angle valve for only 5-10 hp less. With the prop you may be 50lb off the nose which is substantial weight savings and seems to me would be better than the hp difference. I know the Eagles CG sensitivity. I am using the stinger tail spring and Api tail wheel which should be about 2lb off the tail to the good. I cut out the battery tray behind the seat and moving to firewall with lightweight battery. Lightweight starter and alt. I tried using Cameron's W and B spreadsheet with some of the other Eagles data that I thought was close to mine and if I were doing the W and B correct, I only had a one inch movement on the cg but still better than some of the Eagles that people posted. That is a big IF for me doing the W and B correct! Just wondering if anybody thought about this approach? Thanks,
Cary
