Thermaleers Free Flight Club
The Thermaleers are a free flight club that meets on Tuesday mornings at Buder Park, year-round. Models in the 7-gram weight range are “catapult-launched” into the air and minute adjustments to control surfaces change the flight dynamics. Many designs include a “de-thermalizer” to help the model exit a thermal at a pre-determined time.
MVSA members Nelson Itterly and Mike Johnson are also members of the Thermaleers.
