The radiator door is an excellent idea. Light Sport Aerotrek airplanes also have a large radiator with a manual door, and it works very well.

The Rotax manual tells us normal operating oil temperatures are 190*-230*F. Unfortunately our TSi’s rarely operate in this range as the oil thermostat usually regulates the temps in the 160*-175*F range. Too low in my opinion. Therefore when the OAT is 60*F or below I add 1 7/8” blue painters tape a...

This is usually good practice, especially in a bumpy runway, but it can sometimes be a problem in a TSi.

For example, stopping for breakfast in plus 90* temps, or stopping for fuel in plus 90* temps. This is happening to other TSi’s and in particular, one i...
