Cinewhoop made from Eachine Tyro89 components

UPDATE 3/23/20: I have created a significantly lighter version of the frame and top (files named Frame - V2 and Top - V2). The new frame is shorter and features thinner ducts. Without battery, it now weighs 102 grams, 19 grams less than the original. Flight characteristics are improved, although the V2 frame is not as strong as the original. It has held up well so far to minor indoor crashes I've had. ---------------- ------------------ -------------- ------------ ------------ -------------- I'm not as interested in photography as I am in flying outside among our trees and bushes without breaking props on every flight. Cinewhoops do provide great propeller protection. That said, I included a simple cube mount for my Polaroid Cube camera. I wasn't looking for the kind of performance the Tyro89 provides as stock. I just want to putter around the yard and stir up a few squirrels. I used Rimsler Dison's 3" version as inspiration: https://www.thingiverse.com/thing:3492360 Since I had a Tyro89 (2.5" props), I used all its components in this design. Just four parts: 1) Frame (will print on an Ender 2 or larger) 2) Top 3) Camera mount (for Vtx camera) 4) Cube camera mount Again, the electronics are all Tyro89 components. The esc mounts to the frame and the flight controller mounts at 45 degrees to the top. Assembly notes: * Most hardware is from the Tyro89 kit. You will need a few longer/shorter screws and nuts to hold the camera mount, flight controller, and top plate in place. * The esc uses the plastic standoffs - for the flight controller, cut the rubber shock tubing in half. * Wires are all long enough from stock connectors, but it's close. I suggest connecting everything to the flight controller (just like with the Tyro89 kit), and then mounting the flight controller to the top plate. * I hot melt glued the Vtx to the back of the camera and used hot melt glue to support the Vtx antenna. There is no need to access the frequency buttons if you set up Smart Audio. * Note the orientation of the top (front marked with "F"). This is because you must be able to access the USB port in order to make adjustments in BetaFlight. Weight: 121 grams without camera or battery. Flying characteristics: I now have over 20 indoor flights under my belt. As expected, it's not as nimble as the Tyro89, but the indoor flights I've had so far are very encouraging. I'm running 550mah 3S lipos and it has plenty of power. I stop at about 3-minutes with average cell voltage still at 3.7 volts. I think you could coax over 4-minutes out of it. I'm still using stock-like props that are not designed for ducts - got them coming. As I've said, I'm looking for something that will move around the yard with minimal breakage issues. I've been spoiled this winter by the sub-2-ounce tiny whoops - flying indoors and crashing into just about everything without damage. Hoping for the same experience outside.
