I did the KBS a few years ago. Initially it seemed good but proved to be not fuel proof. In addition, it's shelf life was short. To prevent myself from trying it again and ruining another plane, I threw it in the bin. Y2K is great and you can refrigerate it for at least a couple of weeks.
And, don't forget fellows, even though there are no official events for nitro fuel, sometimes it is fun to tip the can and let 'er rip! TS

we are starting to consider a retro D ship with Dooling and 2 lines to blast around with.
