I agree about entry fee situation,
£100-£150 per team is more acceptable if its based on 6 drivers per team
In comparison we have 2 teams booked in for UK Endurance masters which is a 6hr 1/8th nitro meeting.... entry fee was £125 per team and you get an engine and fuel supplied... but trying to get the drivers to cough up £25 towards it has been hard work...
R/C enthusiasts are a bit tight when it comes to anything that doesn't make a toy car go faster... entry fees is the classic... spend thousands on the equipment but moan about paying a fiver to race the kit!
We are looking at running a 24hr electric 1/10th offroad meeting next summer since fitting floodlights to our venue, but can't plan any dates until early next year when the BRCA calendar is sorted
I would try getting the meeting sponsored in order to boost charity contributions, some distributors or businesses may be interested in donating prizes towards a raffle etc.
Its a good idea though, so try and make it work
