Bob,

I am building this very same Stick for a friend, however, we are installing the 15cc RCGF. I have found the 15cc RCGF engineon 15x7 propto be more than sufficient for my H9 Ultra Stick 60 providing unlimited vertical performance, hence, we are using the same set up. Your Stick with the 20cc will be an absolute blast once you get past the prop clearance issues.

Can you provide details on the hardware you use to connect the vertical fin to the horizontal stab? What length and size push rods are you using and what type of ends and fastners?

Thanks
