Having been involved in the Baghdad Bronco project..and seeing the e huge effort that was put in by a few key individuals (I was not one of those individuals..all I did was build and ship the engine to those doing the heavy lifting) I offer one comment and one idea..that are related.
Yes, I agree 100% with those, including Jon, who have noted that project management by one or only a few is paramount. But thos few often end up donig most of the work too. which leads me to...
In this case..since what is being proposed seems to be running along the lines of more a good-publicity and charity project combined (which I like), I think that compensation (or call it reimbursement if you will) of key individuals for key efforts would be in order and would tend to motivate as well. Said compensation would come 'off the top' when the vehicle auctioned/sold and proceeds are in hand for distribution to charities. I'm not proposeing that HAS to be done..but it may be a good idea to consider it up front.
I am not proposing to be one of those that might be compensated either, mind you, - my plate is full with my business to run - but I'm on board for supporting this project if it matures under the right circumstances and withteh right goals. It would - or at lest could if managed properly - make the EB commuity look real good...much as the Baghdad Bronco project did.
