First run of a brand new motor on a cold day, Jeti telemetry shows nicely how efficient the rear cylinder cools. This will allow for very basic cooling setups with only basic (if any) baffle requirements when the cowl is installed.

With cowl on our cooling tubes will be used to guide the air to a) cold air intake for carburetor and b) rear cylinder head and top of cylinder. More videos including in flight footage will follow.
