I'll be using 7inch and 6inch props :

  • DAL T7056C
  • Master Airscrew 6045 RS
  • Gemfan Flash 6042

I normally use CL Racing F4S on all of my builds but decided to make an exception for this build and instead used JBF4 v2 FC, it's basically identically designed flight controller (even using the CL Racing F4S firmware) but it's rated up to 240A and probably more suitable for this setup with 7inch props and potentially 4000mAh 65C 6S battery. One major disadvantage is the fact that JBF4 comes with no SD card reader for the blackbox, instead only onboard dataflash memory is used and at 16MB it's not very usefull (it can record only one 5min flight before it gets full and then it takes 15 minutes to download the log file).

AUW with GoPro Hero6 and 1800mAh 5S battery is 855g.
Built as a long range surfer it's actually reasonably agile quad even on a tight track.

Beautiful build! I like the painted carbon.... need to try it out one day.

Can you post a picture with the battery plugged in? I like the idea of the rear battery connector

I usually feed the antenna between the battery leads to prevent leads getting tangled in props, probably wouldn't happen anyway with short battery leads, but some batteries come with longer cables.

The iFlight XL5 V3 is a fantastic freestyle frame for the price. It features chamfered edges on some very nice quality carbon fiber. My goal for this build was to use high quality components at a relatively low price. Not only that, but I managed to reduce the number of solder points to the bare minimum. I've never built such a plug-in-play quad! The flight controller has an integrated VTX and doesn't..

Update! Happymodel has released a new V2 Frame which uses a more durable plastic. The Happymodel Mobula7 is one of those rare treats to hit the micro scene. Countless models hit the market every month, but this one just happens to check all the boxes. It's a 2S brushless micro with a 75mm motor stance. It's slightly larger than the more traditional 65mm brushed micros, but it's still quite small...
