Too long a story to get into, but while work remains busy, I have been trying since March (the CrazE) to get in some real world flying. Need a more expendable model, as flying has to be from within the perimeter chain link fence at work in the summer. Finally zeroed in on a foam board wing and a cheaper motor, in the event the fence is hit. Still learning the details on building a wing like this, so while others may build it in an afternoon, free time and learning has resulted in a build time embarrassingly longer...
Anyway, the flying wing calculator site says this thing should fly, and the CG is set to the most forward %MAC. To help prepare, I've also been using a RF version. The physics have been set as close as possible to the RW model, so when maiden flight time comes, am hopeful the results will be close to what I've been seeing in RF. The RW plane is pretty much done, and am now setting up the control throws, and soon will set the throttle limits to keep the Park 480 happy on 4 cells.
The RF version is still a bit rough, but it is coming along as well, so figured it was time to share some progress shots. The RF version will get posted, but as its main purpose is to be a guide to being as close as possible to the flight characteristics of the RW plane, the maiden and some more test flights will happen first-- hopefully there will be more than one flight... .
Note: the three polygons represent the CG range as shown by the on line calculator: green is the most stable and red= the "danger zone". I find such markers useful in setting up the physics, as I now tend to model planes from plans and start with the recommended CG location. The polygons will be removed before posting as shown in the Max renders.
Note: I use to see the picture displayed in posts, now just the file name is shown. Has there been a web site change??
