Our Austrialian importer (with some South African roots) is installing the D-motor LF26 on a Tri cubby (tricycle version of the Cuby).
On the photos he send us we can see a very special installation of his radiator. With ducting he is planning to send fresh air to the radiator mounted behind the engine. If this is working it will result in cooler air intake. We wish you all the best.
We already want to congratulate him on the design of the cowling. Great job.
