I will buy him this engine then I am going to build him a 4mm coro airframe, that will look remarkably like I followed the dimensions of the Tiger 60 kit or something,no no inspired by, not copied...
Look at this thread

I also fly with my brother. We have a great time together and share a lot of equipment. If one of us needs a servo/receiver/prop/etc the other usually has one in the drawer.
