.40 Size Exta 300S with a .60 Size?
 

I have an extra OS .60 FS sitting around that has never been run or mounted and am thinking about buying the GP .40 Exta 300S kit and putting in my .60 size engine in.

Too much engine?

Will the airframe handle it?

Sounds like unlimited vertical to me.

Opinions are welcome and encouraged.

Yes the airframe can handle it. I have an OS .91 surpass in mine.
I did however replace the wing spars with spruce spars. It must be
ten yrs old now, one of the first kits.
