Some years ago someone offered an additive to model airplane fuel that would provided a vanila or peppermint odor to the exhaust. Does anyone know where this can be obtained today?

Yes, try Jegs.

Geistware,
Thanks! I checked JEG's website, but couldn't find it. I gave them a call and bingo, they had it! It should last me for quit a while. Mix ratio is 16 oz to 55 gals of fuel.

I use it and get the watermellon or bubble gum. They seem to be the best/strongest. I tried the apple and it is weak.

He said all they had was strawberry, cherry & blueberry. I ordered strawberry. Have you used any of these?

but why why ?? that good ole' nitro smell get's my blood pumpin' !

TxMaxxMedic,
I used something like this some years ago flying ducted fan jets when I lived in Texas (25 years in Clear Lake/Friendswood area, 12 miles south of south of Houston). I used peppermint and would also add extra Klotz oil to get a good smoke trail. The smoke trail and the smell would get people's attention. Besides, my wife appreciated a change in the "odor" when I would come home from a day of flying.

I'm finishing the assembly of a 1/4 scale, Hanger 9, Taylorcraft powered by an OS 160 FX (2-stroke) with a Slimline smoke muffler and smoke pump system.
Since this is a sweet plane, I thought it needed a sweet smell to go along with it.
