my larger H9 EDGE- is just now getting a full pipe installation - I moved the engine forward -to clean up prop cowl interaction but the setup also allows 1" more space up front -behind the engine and shifts c/g forward a bit -the spacer is balsa block sandwiched between ply plates and screwed n glued to the cowl
The look is scale like as more new full scale performance craft have extended spinners .
The header is a stock aluminum one - but the KS ones really fitin closer - I have used many of them
the cowl originally was reworked for a Supersonic in cowl (excellent power but a weeeeeee bit loud)
Once I have the installation all boxed up- I will replace with my other new cowl
The performance with the Supersonic was not a problem the plane is a VTO setup 21.75 lbs and propped for 8400 in level flite.
