Been a little while since I have been on here. Classic example of "baby on the way." I had purchased a Ch650 tail kit, but had to sell it when the baby came 4 months early. With the extended stay in the NICU, Iwasn't sure how damaging the bills were going to be. Thank goodness for excellent insurance. Anyway, I have been re-researching aircraft to build and I have returned to Zenith. I just can't figure a few things out. I really like the looks of the 650, but I will be flying from my farm and have been considering the 750 STOL. I also like the increased gross weight of 1440lbs vs. the 1320 of the 650. When looking at the 650 specs/performance, many numbers are given with various power plant options. I looked at the 750 and it specifies the O-200 for the performance numbers, but it doesn't say what engine was used when it specifies the empty weight and useful loads. Any ideas? Also, I am looking for realistic installed weights for the Viking 130. Thanks in advance
