My first try longer-range build, 113g dry, still looking to cut weight.
Backpack STL, 2 versions:
1st for GPS mount only
2nd: buzzer & sma mount added


  • Custom sdcad cover for caddx turtle added, thinner lipo strap, moved r9mm out of stack for better cooling air, 110g dry now
  • Maiden flight: around 8 mins crusing with 3s 850mah, maybe worse with strong wind, still looking for cutting weight for better flight time, I want 10min+.

I really like your parts selection for the long range eclair. I may have to copy it. I have a eclair 3" I have been doing long range with but your set up makes more sense. the zeus is perfect for this application and opens up room for one more board. Having rth would have helped me a couple of weeks ago. Lost my Eclair about 1/4 mile out. luckily my girlfriend is relentless and found it. Is that gps mount up on thingiverse?
You could shave a couple of grams by ditching the heat shrink and are your fasteners steel or aluminum?

Yeah, the zeus board really makes everything much easier, but you have to rotate the board by 90 degrees to fit in the frame. I uploaded the backpack to thingverse just in case you need it.
For the fastener, I'm using nylon for stack, steel bolts for motor & prop mount, for included harware for the cage: 1x stand off + 2 screw ~ 1.4g, so something like 4-5g for the cage fasteners. I'm thinking to replace the cage with 3d printed canopy but not sure if it's worth.

Thanks for posting the print, got it printed and the quad rebuilt using a tbs nano32. Today took it out to 8/10's of a mile. Wanted to go further but my 4s 650's are toast. It was nice knowing the gps rescue was there to bail me out if the video failed.

This is the 4th installment to my popular "Wizard Killer" series, and is based on the popular Wizard X220HV 6S. As usual, the goal was to build a substantially better quad, yet come in below the retail price of the BNF kit. Here are some of the improvements: Higher quality EMAX ECO 2306 1700kv motors Foxeer's top-of-the-line Falkor mini camera Eachine 25mw-1000mw Leaf VTX with microphone Tools This..

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..
