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.

The CNY specials have just started at banggood and they are pretty darn good with a few historical lows including:

Taranis X-Lite for $99
Flysky Nirvana for $119
Jumper T8SG for $19
Tyro99 for $79
DYS Samguk 2207 $7
Eachine Wizzard TS130 $99

All codes are on my website here:


There are only limited numbers on these items, will keep the page updated for international specials as they come up.

The Taranis X-lite has been a very successful controller for FRSKY but it does not physically support use of the TBS crossfire module even though it is supported in Open TX software. The simple solution is this $8 adapter which I've reviewed below:

It's been a while since I published specials on my page but I have 3 I quite like below:

Emax Hawk5 Bind and Fly $175
SKYSTARS G730L 7inch FPV quadcopter $169
FATSHARK Recon V2 FPV Goggle Glasses 4.3 inch LCD

The Hawk 5 is great value at this price and still a great quad. The 7inch G730L is a heck of a lot of value for a 7" quad having just gone through the expense of building my own. Fatsharks are a little bit of an unknown to me but seem like good specs and a great brand for a budget goggle.

The new Gemfan 1635 (40mm) props are now available worldwide on Gearbest and Banggood. They are available in 3 and 4 blade options with 1mm centre hole for 06xx, 07xx, 08xx motors like on the snapper7, mobula7, trashcan beta 75pro 2 and 1.5mm holes for 1103 and larger motors like on the beta75x and fullspeed tinyleader.

I've ordered in 1mm in 3 and 4 blade to try. I'm guessing by the popularity of these small brushless quads that they'll go in and out of stock fairly regularly so you may need to shop around.

Here are the links below:

1.0 mm centre hole 3 blade 40mm

I've completed my review and DVR for day and night flying at the link below. After reviewing all the 2s (and 3s) "whoops" it's nice to say the the tinyhawk is still really relevant given the excellent design and solid tune for most users out of the box. I didn't test the RTF kit but that sound like a great option for someone wanting to dip their toes into the hobby.
