After building several miniquads I wanted something a little ‘different’ to work on, so I ordered the v4 tricopter from RCExplorer – that’s David Windestål’s site, you might recognise him if you watch Flite Test or Rotor Riot. I figured I’d share some pictures from the build, along with my thoughts. Overall I have to say that I love the ‘copter & it’s a joy to fly, but it was definitely the trickiest build I’ve done to date (despite being the largest overall!) & it left me quite frustrated in several places.
After some simulator time in Liftoff & FPV Freerider using my Taranis, learning how to fly rate mode, I bought a Fat Shark FPV setup to go on my ZMR. I figured having a second frame with no FPV gear on would be nice, so I could be reckless without worrying about breaking the VTX or whatever, so I grabbed the cheap ‘Spec FPV250’ kit from HobbyKing.
I was attracted by how simple the kit looked, what with the (almost) one-piece frame & bullet connectors on everything. But the design of the frame, which has almost no ‘internal’ space, meant that it was actually a bit of a pain to build while trying to keep components safe from crash damage.
The receiver’s antennas were a particular problem. Ideally they should be vertical, but I couldn’t think of any way to mount them vertically where they wouldn’t be at risk of damage (mainly from being pushed into the props) in a crash. In the end I resorted to mounting them horizontally along the rear arms, which isn’t ideal when it comes to maximizing reception, however as this is going to be a purely LOS frame I don’t imagine I will ever fly it far enough for this to be an issue.
Still going to do a range test before I fly it though! Hoping for some dry weather (& free time…) this weekend so I can go maiden it in the park :)
