John Roberts 9 Posted September 25, 2013 Share Posted September 25, 2013 Hello Last year I bought a secondhand Precision Aerobatics Katana MD but I have only recently started flying it. The instruction manual says that "the centre of gravity range is 95mm-103mm measured from the leading edge of the wing root" and goes on to suggest that the optimum CG is at 101mm. Inittially I set the model at 101mm but it was clearly tail heavy in flight. Things were better at the forward most position of 95mm but the aircraft still felt & looked tail heavy in flight. I need to experiment more with the battery postion but I think that I will probably end up with a balance point around 90mm-92mm. Has anybody else experienced similar issues with the same model? I wondered at one point if there was a misprint/mistake in the owners manual or maybe there is some set up trick that I have missed? Any advice or suggestions gratefully received. Thanks, John Quote Link to comment Share on other sites More sharing options...
