Thresher pup 4" from Good Venture Drones. I designed a custom race canopy with a patriotic theme to it (although, it also reminds me of Crest Toothepaste... :D ). Runs HQ 4x4.3 props and 1606 3300kv motors. The stack consists of an ori32 esc and omnibus v7. For now, it has a runcam nano 2 and a runcam backback vtx. The 4s 850's are a good size and give enough flight time to get around the track.
