The Reaper has always been on my list to design, it was actually the tomahawk that put me in the head space to build it. I was thinking about a prop tomahawk and it gave me the idea to make a prop Reaper
It was a really fun project to design, one of my favorite parts of designing planes is making the munitions that come with it. By far the most fun. Building the Reaper is very satisfying due to the size. It’s the perfect size to hold and throw. I cheated the wings enough to where it flies really nicely.

Build tips and pre flight info
I used 100% travel on the ailerons and 20% expo
125% rate on elevators and 0 expo
*The model doesn’t like to fly really slow during landing, I would avoid flying in very still or no wind conditions. It’s much preferred to land and hand tossed into a moderate headwind. I have included optional air fences to glue on the wings to help this.
* with a headwind hand launched the model with a stiff throw on a 45° angle.
Use servo screws to attach a standard motor mount to the rear motor mount. I never needed any glue, the screws held great.
