Gaba gets his for about $18 a gallon. But, that is buying from those that make a bulk buy of about 6 gallons at a time. If you do a single gallon, you are looking at $25-$30.
well if it was that cheap here .... I would definately do it! but I am floored by the costs.
My mate flies planes and helis Nitro (old school Rate only stuff) and he make up his own mixtures and buys it in 20L containers .... not sure if I can use his stuff ... he gave me 20L of it before he sholt through to Australia to live
