Subject: KR>Weight & Balance Flight Data
There were some questions about C/G Range last week.
I would like to add my two cents to that.
I ran some calculations yesterday about my first 12 flights of a stock KR2S
with a GPAS engine.
I have a 1,4in engine mount spacer installed, and had problems during the
first flight with nose up trim.
I installed a lead weight in the tail.
Now I will remove the spacers and calculated an anticipated C/G Range based
on the first data.
I will add a spacer (1,4in) between the prop and engine.
And sorry guys, it is all in KG and Meters (1kg = 2,2lb) (0,33m = 1ft)
The Range is still in percent, that is the most important figure.
Here is the data (out of an EXCEL Spreadsheet):
