TTGT S - for 16x16mm FC/ESC stack

thingiverse

I remixed Gophy's awesome TTGT S freestyle quadcopter frame to use a 16x16mm FC/ESC stack. This quad is an absolute blast to fly! I get around five minutes of flight time with a 550mAh battery. Total build weight without the battery is approximately seventy-five grams. UPDATE: I just added TTGTS_bottom2_16x16_remix_v1.1.STL, which adds fillets to the areas where the arms intersect the main body. I had my arms break in a crash right at that acute angle, so I added the fillets to try and better distribute forces in a crash.

Total parts cost (not including filament for the actual frame) came out to be around ninety USD. Notes: - I was disappointed that the TeenyF4 Pro stack doesn't have an extra UART to use for Smart Audio control of the TX06. I tried resource mapping the PPM pad and the buzzer pad, but couldn't get either to work. If I were to buy again, I'd get this FC/ESC stack: HAKRC 16x16mm Flytower F4 - https://www.banggood.com/HAKRC-16x16mm-Flytower-F4-2S-Flight-Controller-AIO-OSD-BEC-2S10A-BL_S-4in1-ESC-for-RC-Drone-p-1447083.html. It has a spare UART RX/TX pair, and it also has 10A ESCs. - If you're looking to run 3S, you could use this FC (https://www.banggood.com/FullSpeed-F408-Flytower-Part-16x16mm-F411-2-3S-Flight-Controller-AIO-OSD-BEC-for-TinyLeader-75-RC-Drone-FPV-Racing-p-1435359.html) with this ESC (https://www.banggood.com/FullSpeed-16x16mm-FSD408-Part-8A-BLheli_S-1-3S-4-in-1-ESC-for-TinyLeader-75-RC-Drone-FPV-Racing-p-1435360.html) - Here's an alternate battery if you want to save a bit of weight at the expense of flight time: https://www.banggood.com/Gaoneng-GNB-7_4V-2S-450MAH-80C-Lipo-Battery-XT30-Plug-p-1151985.html
