Horse Hockey! The G62 is way too much power for this model and you will end up carving up the cowl for the carb and muffler.
The real plane is a gentle personal home built , not an Extra for pitys sake! If you want to do the dreaded unlimited climb or hover maneuvers you picked the wrong design and you are going to be frustrated with that huge,thick,constant chord ,ironing board of a wing.
I have a 38cc Quadra 400b in mine,and it will jump off the ground in 50 feet and do most inside and outside maneuvers from level flight.The design of this particular engine allows a Bisson side mount muffler and the carb to be completley enclosed in the cowl,and use of the scale plastic engine for total realism.
Depends what you want I guess.........
