If we have anough numbers interested we could certainly approach the Wicksted at War organisers with a proposal for something bigger and better. We would need circa 20 people to put their hands up and commit to being there both days,
and battle twice a day at a set time so that the organisers could draw attention to it over the PA and get a crowd going.
After that, the considerations in my mind would be:
1) shelter for all of the gear - 'Grantham and friends' filled 2 4m x 3m gazebos with display tables down both sides last year + a whole bunch of diorama outside that also needed putting under cover at night to stop it getting ruined by the morning dew, which filled the space that visitors would stand in while viewing the static display in the gazebo's during the day. We could squeeze a few more in but not an additional 15+ tankers worth of kit.
2) Lots of Trees and building to hide behind. (plus bridges etc) The ground is very flat, and if you want to have a proper battle with manoeuver and objectives to fight over, then you need a lot of cover. Denzil and I have quite a bit that can fill up the local hall we use in Grantham, but not enough for the kind of space you need to get away from the static sniper warfare that small spaces dictate.
Danville is listed at 6000 sq ft, I reckon you'd need at least half of that for 10 per side - from experience 2 basket ball courts is barely sufficient to allow you to flank an enemy in a 5v5 (tho again that might have perhaps worked better if we had more trees and buildings?)
3) Access to power for charging - last year there was a model railway display next to us, and a genset had been provided for us to share. We might not be so lucky another year.
4) Camping space for all those extra bodies - there won't be room for all of us on the pitch we had last year.
5) we would need some kind of PA system and somebody to talk the crowd thru what they are looking at, otherwise its just a bunch of toy tanks crawling around a field in the eyes of Joe Public - racing is exciting to watch becuase you have a leader board and a number of laps counting down (and presumably the vehicles aren't all painted in a similar shade of green or whatever

) - everybody can understand what is going on with racing. The finer points of how IR battle works, what the point of the game is, etc, all need to be explained for the crowd to become invested in watching for more than a few minutes.
6) Some kind of pyro beyond tossing smoke bombs around (and hoping nothing catches fire) I've looked into RC pyro before, its not cheap for the control boxes to get started, but if the consumables are only the plumbers candles and igniters than it might be do-able?
7) some kind of barrier to stop small kids rushing in and grabbing/sitting on stuff (yes, it has happened before), or joe public just wandering right through whilst glued to their cell phone...
8.) Inspections need to be done either a people arrive on Friday or first thing Saturday. Must check:
a) their emitter works(!)
b) they take a hit on all 4 sides at a set distance
c) their hit lights are clearly visable in the sunlight - I've seen plenty of 'custom' installs that aren't
d) Their tank is set to the correct weight class (as defined by the RCACN standard - its old now, but comprehensive and is based on average armour thickness which at least lends consitancy to it) The reasons for this are (i) you know how many hits it will take to kill the other guy, and (ii) you know how long his reload is.
Inspections are a ballache and usually most people get bored halfway and start goofing off, much to the frustration of the guys trying to carry them out.
9) Some kind of marker to tell the 2 sides apart - at Danville it was a cocktail stick with a little coloured flag at one end, and a mini bulldog clip at the other
10) We would probably need to know by numbers by November at the latest so that the conversation with the organisers could be held in good time - suddently suprising them in March with a request for access and camping for 40 people, and an area 10 times the size of what we had last year probably isn't going to go down too well...
Plus I would need to talk to Dave and Frank, because they are organising it - if they don't want a weekend of herding cats, resolving bickering, dealing with/setting eyes on certain 'personalities' in the hobby etc, then it ain't happening at all
Anybody got any other thoughts? Various game types have be tried over the years, so there is plenty of info out there (tho some of it might have been lost when they shut the old H*E*A*T forum down?).
