It take more tools to build a great model then it dose a house. The only thing is they are smaller! LOL When you saw that Master scale P-51 on the flying feild you didn't know the guy had to have a full garage full of tools to get it there! LOL The only thing that makes sense is he bought them just like you will a few at a time till he has the garage full it takes to build like the big boys! Happy modeling!
