I have had this idea of a large scale F22 with twin pusher props. Most large scale f22 foam pusher planes seem under powered and this seems like a logical way to achieve more speed with minimal prop extending under the body.
Current design is 52 inches wide and the prop opening can hold two 9" props.
Surface controls: elevons, ailerons
I want to use two 9x8 props pushed by this NTM 1300kv motor on 4S. I want to use counter rotating props but the largest I can find are 9x6. I have not found many other motor options that can push a prop this size any faster but I am still looking.
I currently plan on using 1" foam for the wing and 3/4" foam on the rest of plane. If weight is not an issue I would like to use 3/4 oz fiberglass as a covering with poly acrylic.
I have spent many hours trying to get the design as close to a scale look as possible while trying to keep the model as simple as possible to build, which is not easy. The model below is not perfect but shows the concept and is to scale.
Does anyone see any potential pit falls or issues? Input is greatly appreciated.
