Another amazing design by Dave_C_FPV! Worthy enough to cut in 3.5mm carbon :) I originally printed out this frame in petg and a friend printed some out in carbon fiber pla but I didn't think it would be strong enough to with stand a crash with heavy 1404 motors on it. I edited the center of the fame just a hair to accommodate the Primo style battery holder, but I ended up using a battery strap instead. Being 1404 3850kv motors they are pretty quick and efficient on a 3s Tattu 650mah. But if I really want to crank it up I use a Helination Talon 650mah 4s. The down side to the 650mah 4s is I can really feel the added weight. I need to get more 4s batteries for testing. In the meantime I am going to try some GNB 520 mah 2s in parallel, just like my friend did here https://rotorbuilds.com/build/19874.
