After waiting for almost a year for a frame other than the Armattan Chameleon, and my Xhover Stingy I found it.   The Astro X X5 Johnny FPV frame, super sleek, super strong and well thought out. Being the first Astro X frame I've built, I anxiously awaited the arrival from the second I saw the first teaser pics.

Once it came i have to say i ws shocked at the carbon quality, the fit and the finish.  Second to none!! The arms are skinny but ridiculously stiff. There's two holes in each arm. One for a 20x20 stack and one for the mounting screws which are 30.5x30.5 to sandwich the arm between th bottom plate and arm support x which has only 5 press nuts. The tolerance of the screw holes is tighter than any other frame I've assembled. Although the arms only have one screw through them they don't wiggle at all. Not even a fraction of a mm. Once the arms are slightly threaded with the screws through the 30.5x30.5 holes in the bottom plate then into the arms, you realize that the arms are made slightly long. This adds preload to the arms in the center of the frame against the screws. The addition of the X support pushes the arms perfectly flat with an amazing amount of tension. Finally you add the center screw to lock it all down. Then comes the camera side plates which fit so snug in the top and bottom plate you aren't sure they will even fit. A few wiggles and they slot it perfect. If you purchased the plastic parts kit, the rear standoffs are machined to fit the rear plastic vtx antenna mount. The arm skids, front and rear bumpers fit tight and match the curves of the frame perfectly, as do the landing skids.  The 3d printed GoPro mount is designed to fit the session or hero 5/6 without a protective case. But the quality is awesome.

Awesome build man love the colours and it's so tidy!
How did you mount your GoPro with the case did you cut that bottom lip on the 3d mount?

hi bro! nice build.
How much does the build weight? and how you put that RUNCAM Micro on there? have you used only one screw?

I had a few longer screws from the top plate of my old Chameleon. I have one screw in either side, but to prevent the camera from rotating I have a 1.5mm thick washer on either side of the camera between the camera side plates. This is slighlty wider than the two side plates, so when its fully assembled there is tension sqeezing the camera preventing it from rotating😉

The frame is ultra stiff super responsive. Still tuning the pids to get it just right but with Betaflight 3.5 rc2 stock pids and settings are pretty good.  Feels more responsive than the chameleon a little more hang time on floaty tricks...  better top end and faster punch outs over objects.

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..
