I have seen this stuff in Home Depot also. It was cheap, less than $3.00 a gallon. Called methylated spirits I think. If you were to make your own FAI fuel it would be very cheap, $6.00-7.00 a gallon. Great for that Moki 2.10! Also on this mix the Moki could fly a lot, it gets very good economy on no nitro fuel for the power it puts out.
