Back in Ladder Logic there was a question posted about a helicopter robot. FIRST replied with a list of concerns that the judges would want answers on. Some of the non obvious ones were blade containment and stability, also keeping it in the field. It ws pretty clear that while they didn't want to say NO, they would look very closely at all such attempts from a safety perspective.

What was really fun was all the people running around the National trying to find the "helicpter robot"

Personally I think the battery is the biggest obstacle. While remote controlled electric helicopters have been built, they never weighed anything near what the kit battery does, let alone the rest of the hardware you would need to use from the kit just to control it. I'm not sure a full up R/C helicopter with a gas engine could lift that battery.

I won't say it can't happen, but I don't think the power density is there with the current kit. Though I admit I haven't done any calculations to verify.

Just my $0.02
