this is my workhorse. source one, smashed to death the on a rock. I had to replace lens, front standoffs, top plate cut by a friend of mine. broke few arms, replaced motors from bh r3 to xing E. tramp hv has always been solid for me.i got some hglrc 28A single escs from prmo sales, these are in fact 30A rated with 40A burst. blhelis now lets you use the rpm filtering with either JESC or JazzMaverick so I still use them. I prefer single escs, even the slim ones over 4in1 everywhere except pure race breed drones where wheight is priority. my plan with this build is to slam it, I just need a 3d printed mount for fpv cam. I still have mounted fully addresable LEDs, 3 on top and two on the bottom of each arm. I made those for some long expo photos and the last wintertime when it got dark pretty fast. now theyre usually turned off, but on a switch :D ( LED_low FTW!) I usually rock gemfan 51466 , I jut got some S5 to try as I heard theyre great, what do You guys think?
