Hi Will,

Coloured smoke isn't uncommon in model jets...it was used at the SA JWM I seem to remember.

Red diesel will not do the job, you need a proper dye like the one Hank mentioned that the Reds use. I came by a couple of litres each of their red and blue dye a couple of years back and it did work quite well...but it needed a heck of a lot of dye mixed in with the diesel to produce a decent colour and the cost, if you have to buy it, is quite astonomic (can't remember how much, John Palmer researched and came up with a price for the minimum amount - 50 gallons - and he's at AB tomorrow so maybe talk to him about it). The other thing about this dye is that one small spot on your finger/whatever, will cover everything...it's a nightmare if you have a leak (witness the blue interior of my old Foxjet!), and it will not come off.

See you tomorrow,

Cheers,

Dick

PS...Mick...often wondered why you don't join the Swindon Club so you can stay over on the Friday and fly on Saturday too!
