looks like we can ask just one question at a time with multiple options........isn't it?
Yes, basically. But it can be a poll with many questions and multiple answers/votes, but there is no guarantee that the user will "do one vote per section", where "section" is a set of questions/options that are related.
BTW, I do feel that all this analysis may be unnecessary, just from the discussions here. Because ...
1. There are already polls on EPP planes, including price points.
2. First you need to have a fair idea on how economical you can make them. That should be your STARTING POINT. Figuring out margins would really be a second step.
3. It is obvious the 4ch planes would be the most preferred option. It is OK if ailerons are just in the mould, but not active initially.
4. You will need both versions (bit and ARF), to maximize sales opportunities.
