I have a Ohio R/C Giles 300. Thinking of using a Moki 2.1 for the engine. I would like to use a lighter engine, but will it pull out of a hover?

Here is the plane info:
Wing span: 76”
Wing area: 1100 sq in.
Weight (with Moki): just under 15 pounds (including fuel)

The Moki 1.8 is only 4 oz lighter, but the OS 1.60 weights about a pound less. How is the throttle response of the Moki?

Wing loading with the Moki will be about 31 oz/sq ft. With the OS, 29 oz/sq ft.

What engine would you use to get 3-D performance from this plane?

Thanks for the help,
Jim
