A second opinion and a new perspective can help you eliminate flaws, and suggest possible improvements. I am offering pro bono courtesy testing. To be constructive, I will tell you what I both liked/disliked. Take these friendly suggestions, or leave them. In the end, the choice is yours. The very least I will do is give it a fair trial, and report the results. Simply contact me and tell me what to test and your goals.
By "goals", I mean desired capabilities and specifications. I tend to judge airplanes by their own merits against the designer's intentions. I need subjective benchmarks as established by the designer.
