As far as props go, an 8x4 probably will fly it, but it would be underpowered. Something like a 9 inch or 10 inch is going to make a big difference. I have flown my Simple Stick (roughly the same size as the scout) on a b pack (985 kv) on an 8x8 prop and it flew well - slightly underpowered but still a lot of fun. Cutting out parts of the tail and fuse should work.
