Event Launches
Just an idea for those holding launches you may want to use the Calendar to announce your meet. The new calender is laid out by the half hour or so. Mick

Re: Motor Temperature, Heat Transfer and Epoxy
Hi Gerry, Vinyl ester's have a Tg of around 125°F, motor temperatures can reach and exceed 200°F, so unless you are using low power motors not a good idea.
