Scou:
The wing loading calculator I use is from the mini-iac website. It is an excel spread sheet and it works very well. The link is below. If it doesn't work it is on
www.mini-iac.com under site services then downloadables then excel files. In the excel program it has a paragraph that explains what good cubic wing loading is for an aerobatic plane. I put the numbers in that you listed and the cubic wing loading is 10.93 which is a bit on the high side, but smaller planes usually do have a higher wing loading for their size than the larger scales. 8-10 is listed as good for IMAC style planes. Hope this helps, Travis
