it seems ok lets see after a crashSurprisingly well made for its price. The arms aren't detachable or replaceable, so if you break them you gotta replace the whole frame.A great first timers frame like me and very durable and well balanced. Nearly unbreakable considering that my quad stopped violently by a wall and dropped 1m high onto the ground. Not a single scratch.
The PCB outputs 5v so you can use OPTO escs and power your flight controller and your RX.
However you might need:
1. screws for the motors
2. a few more screws for mounting your flight controller in the middle of the quad.
A great peace of kit overall. Great buy for the money.I'm very happy with this frame given its price and the availability of replacement parts. Overall, if you're just starting out, or you just want a light frame for a fast quad, this is a good frame. If you're looking for a frame for racing/technical freestyle/high speed proximity, you'd probably be better off with something more durable.
-Plenty of room for electronics
-Comes with a PDB that includes a 5v regulator
-Not very durable (I broke 3 frames before switching to a carbon fiber frame)
-Motor holes need drilled out to fit some motors (specifically the zmr/rcx 1804 2400kv)
-Tight fit for FPV camera (had to dremel out plastic to fit a PZ0420M)
**Options for mounting the FPV cam at an angle would be nice, but for the price of the frame, I can't really knock it for that
5 crowns for value
3 crowns for quality
4 crowns overallGreat frame to learn on! Super easy to build and the price is awesome. I've been crashing this thing all over the place and its still in perfect shape!this is what I'm learning how to FPV flight on rather use this over a more expensive frame . flys really greatNice little frame. I just finished building it with the multistar elite 2204-2300 motors with 12a speed controllers and a naze32. I opted not to use the power dist board as it's a bit thin, instead using the king Kong board from my previous biild. And a 5a hking micro ubec.
It assembled easily and once it's together seems to stiffen up. https://goo.gl/photos/BhonHk5cGFGJnEWQ7Simple, fairly robust, and the price is perfect!Great frame, it came with some extras like a spare stand off and a spare anti-vibration ball. I did have to trim a little plastic from my board cam to get it to fit between the front two stand offs. One word of warning though... the box the frame comes in says "best choice of casual FPV" and the title says "racer" may not be a big deal. So far so good! Thanks HKim very happy with this frame, i love it, very light, resistant, and the best is that you can buy all the parts
