Since stricter regulations have been moving in on the hobby, I've been very interested in making a sub-250g HD build to keep my flights in the legal end of the spectrum. On top of that, I'm a bit of a sucker for budget builds, so I tried to make some conscious choices there, too. Thanks to some help from Banggood, I've finally got the chance to make that a reality!

Here is the build I've spec'd out, and why I've made the choices I did.

I wanted a decent frame for this build that would handle some abuse (because I suspect this quad is going to get flown a lot!). I also wanted to make sure it had a suitable protection for the components inside. I settled on the GepRC Gep-PX2.5 Phoenix frame. This frame has enough room for a three-high stack (ESC, FC and cam board) and a 3d-printed piece on the back that will handle the VTx mount, antenna mount, and tubes for the receiver antenna. As well, the aluminium brackets for the camera mount should provide plenty of protection for the camera itself.

Control Stack:
For the flight controller stack, the choice was fairly obvious. I went with the Diatone Mini Mamba. This stack has been around long enough to prove itself, and it's done a fine job of that. The layout works great, it comes with all the wires you need (including a capacitor!) and the price isn't beat by any other product.

Here is my review of the ArrisHobby X140 micro quad. It's a budget micro available from Hobby-Wing, and I think it's worth a look if you're in the market.

Newest build video of mine. Built this quad to use the rcINpower EX2306 motors, and I am thoroughly impressed. These are 10 dollar motors, and they're beautiful. I hope they catch on!

See them here:

Here's a quick FPV video from the Arris X140. This was my first flight with it between rainfall, so it's a little quick and a little erratic. The quad performs fantastic on 3s, so I assume it will be amazing on 4s.

Full review video coming soon!

Got my fli14+ receivers and put one in a brand new build. After the usual cautionary maiden, I had my first real flight to see how it performed. Result: terribly. I expected good results from these, as they look exactly like the Flit10 receivers. But clearly something is different.

Eachine just released their newest micro VTx, the VTX03S, and this one has smartaudio. I was lucky enough to get to test it out, and I found it to be a very impressive unit.

First off, smartaudio works flawlessly, I had zero issue setting it up. Second, the video signal is super clean, I flew out past 250m on 100mW and had clear video. Finally, it's super cheap, only 10 bucks at the moment!

Overall, I think they've got another winner with this one.

The Flit10 is one of the new cheap micro receivers for Flysky. These have been a long time coming, so I wanted to do a range test to make sure they stand up. They do! The tiny receiver has diversity and has more than enough range for what I need. I'm happy to finally have some decent micro receivers for Flysky.

Here is some sample footage from the new Foxeer Monster Pro. Very impressive for a $25 camera.

The video was recorded from my Topsky goggles with an Eachine Pro58 module.

I'll have a full review of the camera coming soon.

I'll share my build videos here, and I'll keep the first post updated with the most recent.

Lots of people say to find a formula and stick to it, but I love building new quads with different parts and seeing how they perform. I think it's fun to see how cheap parts perform, and sometimes you will find a fantastic deal. I've been surprised more than once.

Here is the most recent build I've done.

This is a cheap camera available on Banggood. It has a very wide angle lens and records true 1080p30 video. It is smaller than a GoPro session and very light. I think it's great option for 130-150mm quads, and would make for a good practice camera on any quad, so you don't have to risk an expensive one.

After I received my Topsky F7x FPV goggles, I made this video to comment on how I perceived all the complaints made by people about them. I found them to be quite exaggerated. I have been using these goggles since I got them, and I love them.

I have since received an Eachine Pro58 module, which fits in the goggles like it was made for them, and with new firmware on the module, the image and DVR recordings are significantly improved. I will be making a few more videos concerning the Pro58 module in the goggles and the DVR when I can get some free time and I will post them here.

A quick and to the point review I did of the Gofly-RC CP90 quadcopter.

The frame of this makes it very durable and resistant to crashes, and it flies very well on 3s lipos. There is an updated version of this quadcopter available, and I think it is definitely worth considering.
