(No turbo because of excess heat that has to be delt with and oil return problems when inverted) I posted this same question on the "alternate" website several months ago and did not get a response so I am glad to see it come up here. My preliminary plan is to pick up hot/cold air in front of and in back of the water radiator ala P-51. I ruled out a small radiator in the cabin because I did not want any hot liquids in the cockpit. So, my question, is the radiator exhaust air hot enough to do this ? If there are any problems with this plan please let me know. Like most of you guys I am here for what I can learn not what I can contribute, at least for awhile.
