Now that was simply unfair. Your criticism was that I should rely on the board to tell me which engine is suitable based on my chosen aircraft. However I'm telling you my aircraft is a one-off, so if anyone is going to discover a prop-sizing issue (as you mentioned), it is likely to be me. How is that arrogant?
amaurer,
It wasn't unfair (to me, anyway and I am an engineer as well), it was based on your extremely vague question and nasty responses to some pretty reasonable answers. You should know that if you want a specific answer, you must ask a specific question. Some of the people on this forum have thousands of hours operating R/C aircraft and you WILL find the answer you need. You don't give the aircraft size, weight, mission envelope, your piloting experience, expectations or goals and you ask about a range of engines that will fly aircraft from 13lb up to full scale ultralights. It is rather hard to provide an intelligent answer to a question that vague. Be specific and you will get specific answers.
