Build log Alien 5″

Hi Pilots!

Here is my Build log of my current FPV Acro/Racing boat. Generally, I am very happy and impressed by the Alien Frame, coming from a ZMR250 v2 from FPVModel. I love my ZMR250 Frame, its very sturdy and was a good frame for my first flights I did in FPV. As a first step into FPV Racing, I still recommend a ZMR250 v2 frame as its very cheap and hard to break ( I actually wasn’t able to break it at all ).

Part List:

  • Lumenier LUX Flightcontroller
  • xNova 2204-2300KV Motors
  • Flyduino KISS 24A Race ESCs
  • HS1177 FPV Camera
  • TBS Core PNP50
  • ImpulseRC Alien 5″ Frame
  • HoTT GR-16 Reciever
  • Lumenier TX5G25 VTX
  • Some build materials

Let’s get started!

All Laid out

This is how everything started.

Important to note that I had Issues with the ESCs later. I had to replace them as I don’t have a flashing tool for the required software update in my setup. For anyone facing weird spasm issues and no line to go anymore, replace your ESCs, it helped me.

All Motors are now cleanly soldered to the Frame

Time to place the TBS Core PNP50. This OSD/Powermanager is stripped down, I removed the case around it and changed the jumpers for 12v Output for VTX and Camera. I also switched the cables for thicker ones. I am not going to use the supplied XT60 Connector for the PDB, I directly go to the TBS Core for Power measurement. I covered all solderpoints with Plastidip to protect them from water,

Added the stripped down GR-16 Reciever. I have not found any review on how to strip it down online so I might do a small guide on that soon. I think its very usefull to safe space and some grams of weight.

Now everything is at its place, holding on tight!

Now everything is at its place, holding on tight! Probably not the best soldering, haha

After going through the wiring and soldering twice to check all connections for mistakes, it's time to do the first test! It works!

It works! Note that the ESCs are shining green because it’s the old firmware. Firmware 1.0.1 and higher are blue!

Placed the FC Shield... Next would be assembling the camera where I don't have any pictures - but there are enough guides on the internet on how to do it.

After a final assembly and connecting the VTX and Camera, I can finally add the top plate to finish it up. LEDs are already working here.

After the Initial Maiden Flight, I decided to buy the Lumenier Neoprene Landing Pads. To secure the screws a little better, I decided to dip them in plastidip. So far, it's holding!

So this is my small Build log! Anyone getting an Alien Frame: It’s a beautiful and very nice to build!

    Wow, Amazing Build! Nice Job! Quick question: does the XT60 lead from the TBS core ever get in the way of the props?
    I have a TBS Core Pro (with the 100a current sensor) and are thinking of buying a 5″ alien; my concerns: will it fit and will the props chop up my battery lead :)

    Thanks, and congrats on your AWESOME build!

      Thanks!

      Check out the second to last picture: It won’t hit the props at all! You can use it just fine =)
      Now after some time of using, I also put the power cables under the first strap, just to have it closer to the battery and thus even less likely to hit the props!

      Cheers!

    How did you plug the hs1177 to the TBS core PNP50? did you solder the wires together like you did with the VTX?

    • Schemen Schemen says:

      Hi Michael!

      Yes I soldered wires together. However, I am not using a PNP50 anymore, I switched over to the RROSD which makes everything a lot cleaner.

      Cheers!

    Just stumbled across this build log… thanks for posting. My first Alien 6″ build used the Core PNP50 but I’m putting together a second Alient 5″ build and am exploring other options. What made you switch to the RROSD? It seems like the RROSD and Alien PDB become redundant… did you use a blank plate in place of the Alien PDB?

    • Schemen Schemen says:

      Hey Peter!
      This buildlog is indeed a bit older and thus the RROSD is redundant. I will need to create a new one, which will come soon!
      As for the PDB, I was interested in the OSD part of the RROSD, I wired a bridge from alienpdb to RROSD so I still got readings of my consumtion. Check out for the gear I am currently using, as you can see this build has been decomissioned long ago =).

      • Peter says:

        Love it, thanks for the feedback. The PNP was so convenient but it’s awfully bulky for what you get. I do like the builtin microphone. Decisions, decisions!

        • Schemen Schemen says:

          For the OSD and Mic I use HS1190 on the alien, directly built into the camera, no need for OSD board! =)
