top flite cessna 310 engine question.
 

hi there I jist got from a friend a top flite Cessna 310 arf, very nice plane.
in the manual it say that for 4 stroke engine it recommends two 70 size 4 stroke, I have a couple magnum 52 4 stroke lue heads new in box and will like to get your opinion about if I should use the magnum engines considering that they sra smaller than what the manual requires?
thanks.

To small...

For sure, way way too small. I did go with two .46 fx's in mine.
