Hi!
For a newbie it is! Bad to mount the engine inverted that is...

And let me advise you that the plane you have choosen is not a good one for a first one... be it either glow or electric.

I agree fully with John in the above message.

A much better plane would be a high winged trainer like the Kyosho Calmato or anyone like it. There is lot's of them!

The best way to mount an engine is to mount it side ways!!
