Hi Paul,
I’m flying this La7 since 2011.
29 flight hours.
Last time was.... Today !
Always great.
I’m running it with a Moki 250.
My cowl configuration is very simple. Baffling at the front (baffle wood piece given in the kit), no hole in the cowl exept for the two Moki exhausts, exit of hot air via the side gills.
Temperatures at my flying field are typically between 10 and 25° celsius.
Never had problems with engine overheating.
