Just wondering if you guys ever used or tried the nova rc colling heads if so could you post. thanks

I have the Nova heatsinks for the STS30, Mach427, and LRPspec3. They are durable and work as advertised to keep the engines cool on hot summer days. However, they should not be used on colder days as the engine cannot not get up to running temperature.
