Viper Mk2 RS

so this is my Emax build of the Viper stretched X micro class racer.. Currently rocking 3s and working through the tuning process with the goal of taking the build to 4s. I'm going to change the cut direction in relation to the carbon grain with the Mk3 frames as i suspect while the arms are a bit stiffer the motor vibrations are been transmitted more strongly to the fc with the mk2 design where the arms were cut at 0 degrees to carbon weave. Unfortunately one of the ECSs died on me this morning so until i get a new one i can't continue to try and eliminate the PID loop noise I'm getting on high throttle settings.. i'm also doing a super light 3" version for either the EMAX Rs1106 or the new Sunny Sky 1106 motors for 4s
looking forward to getting it dialled though as they frame is fast an if i can get it flying as well as the spintech powered version it'll be a real weapon

last flight before the esc packed it in

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
