Cooling shroud for the Minari
by Had Robinson
Various manufacturers make cooling shrouds that dramatically lower the running temperature of paramotors which do not have forced air cooling systems, like the Polini or Top 80. Engines running at over 200C will now run at 140C or less. Unlike forced air systems, there are no moving parts because the propeller acts as the fan which forces air through and over the cylinder head. Disassembly of the engine, less weight, fewer parts, and the problems of starter guts getting sucked into the cooling fan and destroying it ARE GONE. All paramotors should incorporate these passive types of cooling systems.
Miniplane-USA should have the shrouds available soon (spring 2019). You cannot use ordinary coupling nuts to replace the OEM cylinder head nuts, they must be class 8 metric. If you need the correct hardware, we have a complete kit $12 + shipping.
