A-Tail quad. Update: Netfab found a problem with the original file, so I have uploaded new ones. One piece print. Scalable. at 100%, fits 6" props. Designed with 5thGen Replicator in mind (scale to max size for 6" props). Scale up (115%) on larger printer for 8" props. or print the A-tail8-1 and A-Tail8-2 files. Made specifically for 8" props without scaling up everything else. 2 Versions. One Plain, the other has a FC tray. Suggested Load out: Motor : 1000kv/1200kv Props : 8"/6" Battery : 1800 mah 4-cell FC : KK2.1, etc.. ESC : 25Amp Q Brain or 4x30Amp ESC Print it. I would try 3 or 4 shells, maybe 50% infill. should scale up or down well for larger or smaller props and motors. At 100%, the front arm is ~9 inches long. 5th Gen Replicator, Scale to max scale. works with 6" props, 8" if you print and attach the extension plates. On Larger printers, scale 115% or larger to fit 8" props, or larger if using the extension plates. OR, print
