Hello Eric

When you say under the cowling. Do you mean inside of the cowling? Or hanging below the cowl. The normal place is below the floor board about 10" ahead of the gear. If you go to member photo albums you will see lots of examples.

I mean inside the cowl.

Mine is not a Rotax but my radiator is mounted where the lower cowl opening is. It works great.

I designed and had built for me my own radiator. I had an all aluminum one made with 1" wide tubes (2 rows).

I use it for the 914 so it would be larger than what is required for the 912.

I chose aluminum because I wanted to save weight and I chose the 1" wide tubes because I run Evans coolant and wanted to get as much cooling surface area for the heat transfer to take place.

My idea was to mount the radiator in place where normaly the oilcooler is mounted.
Do You think it wouldt give temp problems?
I don"t have a radiator yet and an original kitfox radiator is very hard to get in Europe(from the USA the shipping costs are abnormal high)
I am thinking to use a radiator from a motorbike.

Eric, I followed instructions by the Forum, and bought one at McBean's (I can help you with some workable ideas about the cost, if you like). Don't think it is a good idea to not use a radiator in the Netherlands, though.

Hallo Hans

Ik wil wel een radiator gebruiken alleen wil ik die onder de kap monteren.
Volgens Rotax moet hij ong 500 cm/2 zijn.

Vwb de oliekoeler,ik lees vaak dat de koeler het gehele jaar afgeplakt wordt om de olie een beetje op temp te houden.
Olie die niet op temp komt vervuilt erg snel door vocht.

Een radiateur en de buizen kopen bij Kitfox kost een vermogen aan verzendkosten.

Hi Eric, Ik vlieg met [een ander toestel met] Rotax 912 motoren het hele jaar door - en die koelers doen gewoon goed werk. Ze er later op zetten lijkt me lastig en een knoeiboel.

Not being able to read Dutch, would you do that again in English. I feel culturally deprived, being able to only read English (and not all that well either). Thank you.
