I'd be down to 3D print parts for a drag race as this progresses
Speaking of progress -- Yesterday I spent a good part of the day modifying and printing parts for the X-Wing.
In construction, I confirmed the rocket is plausible. Fitting an engine mount in a plausibly sized X-wing will work. There is a path the ejection charge to blast all the way thru the top part of the scale engine. Four small parachutes will be contained inside the scale engines. The weight is in range of plausibility. For the engines, I want to properly size the mounts to use Estes retainers because the black end tips look cool anyway.
The forward fuse is long enough a small amount of clay should keep GC forward of the wing LE (which is forward of the CP experiments)
Through printing iterations, I made several significant design improvements and changes to rev 1.0 -- enough to conclude 1.0 is not going to fly but remain a construction, test, and improvement version. Here's a picture of Rev 1.0 in its "final" form:
Note: The R2 unit will be printed and painted separately on all revs. The Canopy will be printed in clear PLA.
Rev 1.1 will include the following known changes:
1) Balsa wings will no longer go thru the fuse. 3D printed internal wing mount plates were added to the rear fuse. This will save weight and increase strength.
2) Rear fuse was clipped (non-scale) to reduce tail weight.
3) Almost all internal fuse structural supports removed to save weight
4) Engine mount scale detail will be removed, reducing weight and drag. A purpose-driven design sized for the Estes 18mm motor mounts and screw retainers will be done.
5) Cannons will be narrowed and slightly altered from scale to reduce wingtip drag.
My 3D printer is about done with the Rev1.1 fuse upgrades. I should have some Rev 1.1 photos later today.
