I've recently completed my review of the happymodel larva-x and have also covered off
  • Setup
  • Custom PID tune
  • Custom filters
  • Durability tests
  • Comparison of onboard DVR to goggle DVR

It's a great little quad but there are some durability question marks around the motors in particular and as you can see in my review, Happymodel are already working on a response. That aside it's a great value, fast, nimble and very quiet ultra light micro 'toothphick' that is well suited to park flying and other environments.

Here is my review of the Skyzone OLED FPV goggle which I think will make a real mess of Fatshark's dominance of the market at the premium end:


Here is my summary and recommendations snipped from the article:

As you can see from my testing these are very comfortable goggles with a great built in receiver and good menu system and most importantly, outstanding screens. Since your goggles are arguably the greatest sensory connection you have with you drone, these fantastic goggles make a big difference in enjoyment of the FPV experience. Not only that but I can also say that the extra clarity, contrast and resolution makes for a greater ability to see and hopefully avoid obstacles.

Like many other goggles on the market though the included accessories are disappointing; you will immediately need to invest in better antennas and a battery. See further below for my recommendations there.

Should you buy these? If your budgets allows I would say yes. Being around $400, they sit in between the new "budget" range of binocular goggles at around $240-$300 and the premium goggles at $500+. If you cannot afford more than the budget range I'd recommend the Fatshark Attitude V5 which are still great goggles as I reviewed here. For what it's worth the SKY03O have now replaced the fatsharks as my regular goggles...

I've recently completed my review of the fatshark attitude v5 including the obvious comparisons between the now competitive $240 - $300 FPV market. These have replace my Aomway Commander V1s as my regular goggles and here is why:
  • They have bright and clear OLED screen which allow me to see more detail
  • They have the removable module that allows you to upgrade to rapidfire etc. if desired.
  • They have very good antennas included as stock
  • They have the legendary Fatshark support
They do of course have their downsides including fatshark's stubborn refusal to integrate more of their "modular" design but I (personally) feel these are outweighed by their benefits.

See below on my full upgrade guide for the Happymodel Mobula7 / Eachine Traschan. None of the mods listed cost more than about $5 and most are free.

Areas I cover are:
  • Frame upgrades
  • Reception improvement
  • Bettery and connector upgrades
  • Propeller uprades
  • Tuning/filters/betaflight

Here you go: https://www.quadifyrc.com/tips-and-tricks/mobula-7-upgrades-the-complete-and-final-list

This has taken the Mobula7 about as far as I want to go and have better performance, battery life, range and durability than when I started. A lot of this is opinion based but none of the upgrades I've recommended are more than about $5 so take as you will.

Happy flying!

Recently I've built a 5" Freestyle quadcopter based on the best value components - not the cheapest but the best price/performance ratio (i.e. bang for buck). For me the price came to around $150 using typical coupons and discounts

This quad has since been built, setup, flown, adjusted and then flown a lot more. I'm now in a position to pass judgement over all of the components and will then cover as the quad in total. For each I'll look at the positives and negatives and then go into a little more discussion with my recommendations which you can see at the link below:

I've finished my tune for the Mob7 which has used a lot of Mark Spatz's (UAVTech) awesome work on betaflight.

Here is the article that has screenshots of all the new settings, CLI text and even a full Diff.


If it's good enough to make me look passable as a pilot it can't be too bad - here's the flight DVR

I've finished a fairly comprehensive long term review of the 2019 Aomway Commander V1s and the inevitable comparision to the V1 which I've owned for 2 years. I've also summed up the key competitors to this goggle and their advantages/disadvantages.

Hope you enjoy:

Full review can be found here:


Here is my summary and recommendation taken from the article:

The Sailfly-X is a very low cost "toothpick-class" micro brushless quadcopter from Happymodel, the same company that released the popular Snapper7 and Mobula7 micro quadcopters. It is well equipped with propellers, flight battery and even a spare canopy. It is ultralight meaning it can achieve high performance even with small batteries.

The quad is very well balanced component-wise and offers excellent control and power on 2s and outstanding power on 3s. The light weight comes about from the simplified components namely the main board which includes flight controller, 4xescs and a receiver plus an all-in-one vtx-camera. Being lightweight it has excellent durability from my testing so far. A further advantage of the low weight and high thrust is the exceptional flight time - a low cost 2s 300mah battery offered strong performance for 4-5 minutes of flying time.

This is a very easy quad to recommend - it offers breathtaking performance given the size, is extremely durable and offers exceptional flight time. This is even before we consider the price which around $88 at full retail which is remarkable and worth buying just for components to use on you own build (components which are not often discounted at time of review...). One of the sacrifices made to

After completing a full build article here I have been flying the Hobbymate Asteroid for a few weeks and have completed my review. This review is text/pictures and embedded DVR so it's much easier to scroll through than a video review (IMHO)


The full article above but here are my key findings:
  • This is a very premium kit for $140 and genuinely capable of 3-6s (you can choose 2700kv for 6s or 4300kv for 4s)
  • It is capable of 91mph+ on 3s or 106mph+ on 4s (GPS readings)
  • I feel the motor kV is a little too high for 4s but this can be resolved with a throttle limit
  • I was sceptical about using an EOS2 cam for FPV but the 4:3 ratio variant actually works well
  • Given the power of the motors and strength of the frame it is light at under 140g

The Hobbymate Asteroid is a new 3 inch quadcopter that is available in kit, BNF or PNF formats that is available with motors and electronics suitable for 4s or 6s (!) operation. The purpose of the blog linked is to show how I have built in close detail and how I have set up betaflight software for optimal performance. Note you can spend an extra $30 to have this build with a FRSKY receiver but I always like to tinker and optimise my build which is why I have chosen this path.

Personally I prefer to build myself, part of the fun of the hobby. Documentation not so much but now it's done!


I'll follow up with the review shortly but boy this is crazy quick in a straight line. With a CNHL 650mah 4s and a 80% throttle limit it's faster than anything I've flown. I plan to put a GPS on to verify.

Unfortunately it sounds like Kabab got shafted by happymodel on this one but for what it's worth I've written an article below analysing the components they have chosen and my thoughts on them in some detail.

I've just finished writing a step by step tutorial to add USB charging to your Taranis X-Lite by installing the $10 Fullspeed charging module.

There are about 30 pictures with 24 steps to hopefully make this straightforward. If you can solder up a flight controller then you can probably install this.

Full tutorial is here:

The Emax Tinyhawk is a 1s brushless whoop-style quadcopter that has steadily grown on me since I first reviewed it here. It's certainly not the fastest but is probably the most well designed ducted quad available at present. It comes stock with very good 3-bladed emax props that perform well except that lack thrust when running in reverse meaning "turtle mode" does not work. I've installed and reviewed their new 4-bladed props where turtle mode works and how they perform in general.

Read the rest of the article here including flight performance, weight, impact on efficiency etc.

I've finally finished my build, setup and review of the Eachine Tyro79 in text/picture format.

Given the spec I was expecting it to fly like a pig but it was much more nimble and certainly more effecient that I'd expecting.

The camera started off ok then lost the ability to see in shadows at all so I'd budget $15-20 for a replacement. Is it still a good deal for $95-100? I think so but it is closer to the price of other 3" PNF quads.

If anyone is looking to upgrade to the V3 (trashcan) frame I can strongly recommend it, even if you do mount it backwards.

It gives the strength I was always looking for in the frame without hurting the weight or flight performance.

This step by step walkthrough was written to help newcomers or those less confident - no soldering, cutting, drilling etc., just bolt on an 5-20minutes.


I'll be puclishing more articles shortly on bang for buck upgrades on the Mobula 7 to improve performance, range, efficiency and battery life as well as durability.
