I was looking for some opinions on which size engine to use on this plane. Pondered a decent .46 ( say a TT Pro .46 with the Tower Hobbies muffler ) or possibly a Magnum XLS-52 although I dont know a whole lot about this engine. Would like to get into MVVS's and place a .49 on it but dont want to deal with the 5% nitro issue when the other engines I have / plan on buying use 10 to 15% happily...... read in some other forums about using an extra head shim and 10% nitro but not sure how well this works. I'm not an overly experienced pilot and figured that a 60 sized engine might be too much. Would greatly appreciate any and all thoughts pertaining to these issues. Thanks !!
