Hi Folks,

I have the GP J3 ARF and I plan on installing an OS FS-70II Surpass 4-Stroke. The instructions call for the engine to be mounted on its side which forces much cutting of the cowl. I think that this detracts from the overall great looks of this bird and I was thinking about mounting the engine inverted which will result in less cutting of the cowl and generally better appearance.

This is my first 4-stroke and I am wondering if there are any problems associated with running the engine inverted. I know about hydro lock - is there any other concern that would make side mounting a better choice? I would prefer a better running steup over a more cosmetically pleasing one, however, if I can have both I would like to mount the engine inverted. Thanks in advance for your assistance/opinions.

Steve
