Review: Mobula6 Tiny Whoop – The Best Ever Made?

One year on, the Mobula6 from Happymodel is still one of the best Tiny Whoops on the market. I broke mine and got myself a brand new one, so I though I should take some pictures and talk about why I like it so much.

Where to Buy?

You can get the Mobula6 from these vendors:

• Banggood: https://oscarliang.com/product-htw5
• GetFPV: https://oscarliang.com/product-489e
• RDQ: https://oscarliang.com/product-skdt

There are two KV options, 19000KV and 25000KV. I recommend the 25000KV version as it’s more “future proof”. If that’s too fast for you, you can always turn the power down by scaling down motor output in the flight controller software (betaflight). If all you care about is efficiency/flight time and not speed, then 19000KV is perfect for you.

It comes with the following items in the box:

• 1 spare set of Gemfan 1219-3 Propellers
• 4 x 1S 300mah 30C LiHV Battery
• 1 x S Lipo/LIHV USB Charger
• 1 x Propeller removable too

Why I Like the Mobula6 So Much?

Love flying the Mobula in the house on a rainy day, you can challenge yourself and fly acro mode, but I normally just fly in angle mode. Not doing any flips and rolls next to my TV! :D It’s easy to control and setup, should be great for beginners as well as experienced pilots.

It’s not really suitable for outdoor flying because it gets blown away by the wind easily, and the range isn’t great either due to the low power VTX and SPI radio receiver. But that’s totally okay for flying around in the house.

As a tiny whoop running 1S LiPo, this thing is fast! It hovers at around 45% throttle and yet it’s very agile and has so much control. Default rate is a bit sensitive, so you probably want to adjust it to your liking, but it’s just a ton of fun flying this indoor.

The Mobula6 flies very smoothly out of the box, I didn’t have to change any of the PID or filter settings. And it’s quite efficient as well, I get about 4:30 minutes of flight time using the included 1S 300mAh LiPos. Those batteries definitely aren’t the best quality, but enough to get you started. If you want better 1S LiPo check out my round up.

The Mobula6 is super easy to setup: bind your radio with the quad, assign an arm switch, and you are ready to fly! It took me less than 5 minutes to set everything up.

It’s pretty durable because it’s so light. Like I mentioned, I only broke my last one after a year of flying and constantly hitting the walls (damaged frame), if you are just starting and fly slower, yours probably will last longer LOL.

Camera angle is actually adjustable which I absolutely love, it’s great for different flying environment, and that’s not possible in a lot of tiny whoops.

Everything is integrated into a single board: FC, ESC, radio receiver and VTX. This results in a super clean looking build and it’s easy to troubleshoot. Yes, if one of those things broke you have to replace the whole board and it gets expensive. But I haven’t had a single failed board yet, it’s been pretty reliable so far.

It even comes with a simple USB charger for your LiPos!

How to Setup Mobula6?

The included manual is very detail on explaining how to setup the Mobula6, here are the steps I took to setup mine for first flight.

If you got the Frsky version, here is how to bind it to radio transmitter (mine is the TX16S). First, go to CLI in Betaflight, and enter:

frsky_bind

This puts the Mobula6 in bind mode, then on your radio, select a model profile that uses the Frsky D8 protocol (you can create a new profile if you don’t have one). Scroll down to Internal RF and select “Bind”.

The quad should bind within 5 seconds, then you can just exit Betaflight and remove the USB cable.

There are a few things that I had to change in Betaflight:

• In Receiver Tab, change channel map to default (AETR), and increase RC / YAW deadband from 1 to 3 (this is to reduce stick jitters)
• In Modes Tab, assign a switch for arming. In fact i didn’t have to change anything here as the default was already what I normally use

That’s it :)
