This is great erans, thank you! You took out a lot of time to document your work and I appreciate it. I will use some of these ideas on my current project that I am just finishing up, a Sig 1/3 scale Spacewalker with a Saito 300 twin. I am just starting on organizing the batteries, rx etc. There is more room than in the Pitts. For such a wide fuse on the Pitts, my big hands can get cramped in the Pitts pretty fast!
