During my annual/condition inspection, my mechanic showed me how the Rotax was designed and showed me the fitting adjacent the carbs that hot coolant flows thru. So, no need for carb heat it’s built in.
I believe RV12JT has a Sling aircraft. Sometimes important details are left out.

That being said I have used it except during preflight runup and have never experienced carb ice.
A lot of testing (including the use of temp sensors) was done during the early development of the RV-12.
This was more for evaluating what benefit in performance there would be if a cold air induction system were used (yes, even that was tested but found to not be worth the added cost and complexity).
This testing (and Van's is locate in the wet Pacific North West), along with the accumulated flight time of 650+ RV-12's flying many thousands of hrs around the world, in widely varied flight conditions, has provided data that indicates carb. icing is not an issue.
I?ve got hot-water carb heaters on my RV12

This was a recommendation from another UK-based builder and it seems very common on many 912ULS engines here even if not particularly on RV12s.
Scott,
I just installed the Silent Hitek VR and cowl. Will this impact the potential for carb ice?
