These add-on heatsinks are just what the doctor ordered, for installations in helicopters, in models lacking good cooling airflow, for sweltering summer days, or whenever you need to push your controller harder. The heatsink comes with a section of strong, transparent shrink tubing, allowing you to remove the stock thin heatsink and install this new heavy-duty unit. Fits Hyperion Titan 50A and 80A Controllers, and many other-brand controllers with similar size, in the range of 40A to 80A.
