RE: Can´t get the static margin right
WS, thanks for the help!
The wing aerodynamic center (AC Right?) comes out at 5.88 inches back from the leading edge. and the prop is 26.3 inches to the front from that AC. The engine is an Aviomac 120cc twin and produces about 10HP. The prop is a mejzlik 28x12.
I don´t have the specs for the engine, as the manual doesn´t say the HP rating or static thrust it produces, but I have a ZDZ80 and that engine with a mejzlik 26x10 produces an easy 50 lbs thrust and has 8.5HP, so I´m gessing here that the minarelli will give me somewhere around the 60-65 Lb thrust range. It does give me 6100rpm with the 28x12.(and only has one gallon run on it)
I hope this is the information you need for the calculations and the help.... I´ll be standing by for your numbers
Thanks WS
John
