Hi,Not sure this is the right place to post this, but has anyone calculated/estimated the moment of inertia in pitch (Iyy) of the easystar.Thanks.Patrick

"At the moment, i have just put in a reasonable values for the lift and pitching moment coefficients due elevator deflection seeing as I had no data. I would be interested if you have more realistic data that you are willing to share. The simulink…"

"TCIII,

Do you know if it is possible to do this with the futaba 6ex or would I have to modify the code to read the mode selection from two input channel (6 and 7) on the APM for the two (2 position) switch on the 6ex radio?

Thanks.

"Hey James,

Thanks for the info. I am only doing a longitudinal model of the easystar in Simulinkg to check elevator responses based on an optimal controller. I am using your datcom generated tables for the lift, drag and moment coefficients needed…"

"No, I don't have the equipment to do so. It might be a software issue, i will try to look into it.

Good luck."

"@Kristofer

I am having the same problem as you are. Xbees are working properly but I cannot send/receive data from the APM. Have you made any progress?"

"Thanks for the answer Chris. However, will it work better with added ailerons?"

"Hi,

Do we need to add ailerons for the easystar for it to work with the new ardumega+oilpan?

Thanks,

Patrick"
