Thanks for the input. My kit has not arrived yet and I'm wanting to know how wide the fuse is at the firewall to help decide what engine to use. I'm thinking of an 18cc gas or a .90 4 cyle Saito or OS. I found a nice little Saito 90T twin, new in the box I'm considering, but it's about 6" wide and I don't know if it will fit without just hacking the nose off.
I think I'll do the curved tips as well. The canted ones look pretty cheesy and it is a simple mod to add a nice tip to a wing.
