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.
