Got my Speedo Pro Lite Mk. II yesterday and now it's nearly ready build.
Just trying to balance the plane to your reported CG between 80-82mm.
This plane will no longer be a lightweight thing, that's for sure.
By using a 3S 1000mAh LiPo there's still about 130g of lead needed in the nose. It seems that it's more useful to take a little more lead in the nose to be able of relocating the battery for balancing after the maiden flight - although there are only about 1,5cm for moving the battery...
By using a 2S 1000mAh Lipo effects more lead but more place for relocating the battery...
Is this correct or is my thinking wrong???
