I hope this doesn't come across the wrong way, but speaking from past experience, while the awards may be 'fun' to get and to also see what other users have done/achieved, it does take a fair bit of work for a small group (or even just one person). The problem then gets compounded if/when that person moves away as this void then needs to be filled by someone else.
For me, flying multi-rotors and being involved in projects like this needs to be about fun, and keeping things in perspective.
My concern is that the time taken for rewards may not be that rewarding for those directly involved and may take away their time that could be better spent in other areas such as working on future developments or just being able to get out and fly.
Hope this makes some sense and I also hope that this is not taken in a negative manner as that is not my intention.
