I just joined this forum and i'm new to the rc scene but I do know this methanol will only condense into droplet at extremely low tempratures.

Methanols evaporation point is around 75 degrees f and it freezes at -126 degrees f. You can pretty much bet that condensation build up on the inside of a bottle is from the air content inside the bottle from infrared heating.

I use methanol extensively in my occupation and at temprature down to -75 degrees f and I have only scene it condense to droplet at temps below 0 degrees f.
