Default P38 new build 90" wing motor mount

I am building the plane now and have 2 maybe problems

1# the manual shows motor as a side mount and a lot of cutting of the cowl
but there is lots of room if you mount them upside down and less cutting is this a problem?
using 2 91=4s
2# will i have to reverse one of the motors counter clock wise one of the guys at the field said I would??
not sure?
I have a Twin Star and have no problem

Thanks and have a great day

1. Inverted motors run just fine, IF adjusted properly, use an OS "F" Type plug, onboard glow igniter would be a plus. 2. And NO you don't need to have a reverse crank in one motor for the plane to fly. Twins fly ALL THE TIME with two normal out of the box motors, spinning in the same direction....

Thanks I have a low sport wing and its in inverted and have no problem at all
and sure are glad that I don't have to reverse the motor never done that before would have to find out how to
then hold my breath if it would work.

Thanks again
