What is difference between X-Frame and H-Frame?

FPV quadcopter racing becomes more and more popular, most of pilots like to diy FPV drones, but many beginners are hesitant what they choose the FPV frame: H frame or X frame? What is difference between X frame and H frame?

H-Frame

H-frames as the name suggest form extended arms from the body that form a shape of the letter H. The H-frame drones were the first drones and have continued to become popular to many over the years. They boast of very strong but heavy frames, they are capable of carrying maximum lots of FPV gear and running a LiPo battery. They have a relatively wider base guaranteeing them stable rolls.
I would confidently say they are good if you are a starting FPV race due to the capability and durability factors especially the batteries of H-frame drone tend to last longer since their positioning ensures they are not easily damaged.
It also makes a suitable best drone frame for racing as it offers plenty of room for easy build and modifications.

X-Frame

X-frames stand out as the big names in racing and freestyle. Configured in an X shape that characterizes its arms it guarantees stability from the centralized center of gravity.
They comfortably perform stunts, rolls and flips. They are also characterized by a symmetrical pitch and roll axis.
Their battery is however more vulnerable in case of a crush due to its location at the base of the done.
X-frames are the best FPV racing frames due to flexibility and predictability in their handling.
H-frames may stand out for beginners in FPV racing but X-frames are rated the best drone frame for racing.
Other popular frames include the v-tail, hybrid X and stretched X frames that are modified for different capabilities and performances. A disadvantage of the unpopular racing drones is that they require custom motors and some parts. That could be a real hustle when you require replacements and spares.

The different frame you need to choose the different battery. For H frame, you’d better to choose long size batteries, such as Tattu 450mAh 2S or 3S or 4S 75C lipo batteries, they all fit H frame perfectly. For X frame, I recommend Tattu 1300mAh or 1550mAh 4s 95c square lipo batteries.

Which battery for Mini FPV Drone: 2S or 3S?

Last week I received from Gens Ace two Li-Po batteries for review. The Tattu 2s 800 mAh and Tattu 3s 450 mAh. Firstly, I thought about making an individually test of each battery, but latter I found it more helpful to make a side by side comparison of them.

Both Li-Po batteries are suitable for micro class FPV drones like the Blade Torrent 110 and KingKong ET series. Weighing about the same (~42 grams), I’m curious to find out which one will perform better (top speed vs flight time).

For my tests I will use the KingKong ET125 drone, which weights about 120 grams and it is equipped with 4-in-1, 10 Amps ESC (2-3s rated) and?7500 KV brush-less motors. Roughly, the number before “KV”; represents RPM/Volt (under no load!), so higher battery voltage means more RPM, respectively higher speed.

2s-800mah-vs-3s-450mah

Which battery is best for micro racing drones, 2s or 3s one?

Disclosure: I received these two LIPOs as part of a product review collaboration with Gens Tattu. Although the batteries were offered for free, all opinions in this article remain my own and I was in no way influenced by the partner.

Both batteries came well packaged and, as I requested, with JST discharge plug. While both LIPOs weights about 42 grams, they have a bit different form factor. As usual for Tattu batteries, they came half charged, about 3.82 V/cell.

Tattu-2s-800mah-review

Tattu 2s 800 mAh LiPo specs

  • Number of cells: 2 (2s);
  • Voltage: 7.4 V (3.7/cell);
  • Capacity: 800 mAh;
  • Max Continuous Discharge: 45C (36A);
  • Discharge Plug (drone side): JST-SYP-2P;
  • Max Burst Discharge: 90C (72A);
  • Dimensions: 51.6 x 25.6 x 21 mm;
  • Weight: 42 grams.

Tattu-2s-800mah-review-vs-2s-GaonEng-550mah

As the stock battery of the KingKong ET125 has only 550mAh, I’m expecting at least 1 minute bonus of flight time for the extra 250mAh. Weight difference between 550mAh and 800mAh is about 7 grams only.

Tattu-2s-450mah-review

Tattu 3s 450 mAh LiPo specs

  • Number of cells: 3 (3s);
  • Voltage: 11.1 V (3.7/cell);
  • Capacity: 450 mAh;
  • Max Continuous Discharge: 45C (20.25A);
  • Discharge Plug (drone side): JST-SYP-2P;
  • Max Burst Discharge: 90C (40.5A);
  • Dimensions: 54 x 29 x 13 mm;
  • Weight: 41 grams.

Tattu 2s 800 mAh vs Tattu 3s 450 mAh

First off all, powering your drone with higher voltage batteries (like 3s instead of 2s) can produce permanent failure of electric parts. My suggestion is to check the “s” ratting of each individual component. For example, the motors and ESCs could be rated for 3s, but the VTX only for 2s.

2s-800mah-vs-3s-450mah-review-testing-tools

After five charging/discharging cycles, I fully charged the batteries at 1 Amp. As you can see in the comparison table bellow, both LIPOs ended well balanced.

2S vs 3S

Real world test

Next day, with confidence I went out to do some real world test. Firstly, I loaded the 2s LiPo into the KingKong ET125. As you can see in the video bellow, due the strong wind gusts, my flight was pretty erratic, so the results are not too relevant. I need to repeat it in more calm day.

Although, KingKong clearly says that is risky to use 3S LiPo batteries with the ET125, it worked very well. I noticed some improvements, but you need to be a damn good pilot to take advantage of the extra speed provided by the Tattu 3S 450 mAh. IMHO, 7500 KV motors are just fine with 2s batteries, especially with a light weight frame.

Tattu’s “Less is more” aka “Less weight, more flight time” slogan, proved to be pretty fair. While their 2s 800mAh LiPo has ~19.05 mAh/gram storing capacity, the 550 mAh Gaoneng LiPo has only ~15.71 mAh/gram. Compared to stock battery I got more than 1 minute extra flight time.

Tattu-2s-vs-3s-review-verdict

Final words

Whether you are looking for extra power for outdoor racing and freestyle or extended flight time for indoor practice Gens Ace Tattu has the proper battery for your micro FPV drone (Blade Torrent 110 / KingKong ET125). You can find the 2s 800 mAh for $9.99 and the 3s 450 mAh for $9.89. Free shipping to US is available for orders over $49.

FAQ About Basic Knowledge of Power Bank

What is power bank?

Power bank serve as an extra battery’ or external charger for your phone or other electronic devices. It is a portable power source built of rechargeable battery, packed in a small case that can be carried in a handbag or purse. It has at least one input for charging and another recharging port that can be connected to a standard USB cable that can recharge portable electronic devices like smart-phones, media players and tablet PCs.

Most of the newest power-bank models, arrive with built-in Lithium polymer battery, which known by high efficiency and long lifetime.

How do I know which power bank suits my device?

Depending on individual needs and requirements, there are several general criteria to consider when selecting a power bank:

a) Capacity

For example if your phone battery is 1500mAh and is 0% now, a power bank with 2200mAh can charge your phone 1 time. If your phone battery is 3000mAh and is 0% now, a power bank with 2200mAh will not be able to charge your phone to full because the phone battery capacity is higher than the power bank. If you require a power bank that is able to charge your phone several times, you need a power bank with higher capacity.

b) Number of output

1 output to charge 1 device, 2 outputs to charge 2 devices.

c) Output specification
