Hey there. I believe that george miller used to plan a a-10, and is now offered by iron bay in kit form, or aka craig aviation. I was going to buy a jet kit from john craig at craig aviation and he was so kind, His prices arent too shabby either. I believe the a-10 is in the vecinity of 500.00 for the kit. It is a twin .46 powered and has a 70-some inch wingspan. Also i would recommend jet hangar hobbies for .46 size jets, but i have heard that these aircraft req alot of building (cutting hatches), but once you have them done they are really nice. If you are looking at GREAT jets, i would recommend yellow aircraft and their f-18 hornet single. I am currently building one that i bought from shaun evans (YELLOWAIRCRAFT SCREENNAME). The kit is great, the instructions are awesome, and it shall fly very nice, i have seen many. I would recommend staying away from .46 jets, only for the fact that once you buy the engine, fan and pipe, that is it, pretty much they are non transferable, because not many kits are made for these size units anymore. That is just my input, hope it helps.
