Adaptable ballast spreadsheets, using array formulae

[updated 30 October 2018] 

F3X pilots love ballast - it makes our models fly faster! The problem is knowing how much to add, and where to put it to achieve a particular CG.

One option is to employ a trial and error approach, with the help of a CG gauge. However this can be very time consuming, especially with complex ballast configurations. It's so much easier - and far more flexible - to use a spreadsheet as the primary method, with a CG gauge to check the results.

Here's a publicity shot by MKS, using two of my images. It shows Joel West winning the recent Welsh Open. I think their graphic designer has done a rather nice job!
