I myself have built 14 different ARF's All needing something to satisfy me! Could they be built stock some yes / some no. My own experience with these models is as most. Think they are a great Bang for the $ Yes, they are some work, but my ZERO 120 I love! Great flying plane. I have not finished the P-40 yet, but after checking it out seems like it will be another winner. I've had just as much problems with my GREAT PLANES STUKA with paint coming off as my zero. There is good and bad in all... We just have to figure out how to make them as "WE" want to make it to our standards. If you need A+++ out the box buy that $700 arf. I spent $800 to get my Zero in the air, not bad for a 72" wing warbird gas powered.

All I can say is ask questions, sort it out and have fun...
