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.

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.

Tattu 1800mah 4S 75C Battery review: long flight time for FPV drones

Today we’re going to find out how long it takes to charge the Tattu 4s 1800mah 75c and what the real world flight time is, in comparison to 1300 mAh batteries which are more common for racing drones.

When it comes to racing quadcopters, flight time is not as important as it is in the case of cruising drones. More important is the take-off weight and you need to keep it as low as possible. More weight means less agility and lower speed.

By comparison, the Tattu 4s 1800mah 75c has 193 grams and the Tattu R-Line 4s 1300mAh has only 165 grams. I’m very curious to find out if the extra capacity (500 mAh) will counteract the increased weight.

Review of the Tattu 4s 1800 mAh 75C Li-Po battery

Although I received the Li-Po about a month ago, only now I had the time and mood to review it. You know, battery testing/review is pretty time consuming.

Battery comes well packed with charging plug protector and safety instruction. At first look it seems very well made with good quality terminals.

Battery pack measures around 90 x 33 x 30 mm (L, W, H). Due to the aluminium envelope, the Tattu 1800 mAh weights a bit more than other 4s Li-Po batteries with same capacity. After a bit of research I found out that this producing technique provides not just better heat dissipation and impact resistance, but also compression, in order to minimize puffing during high discharge.

Tattu 4s 1800 mAh 75C battery technical specs

- Suitable for FPV racing drones;
- Minimum of 1800 mAh storage capacity;
- 4 cells of 3.7v. Total voltage of 14.8V;
- Total power of ~ 26.64 Wh;
- Up to 5C charging rate (do not exceed this value!);
- High discharge rate (75C);
- Max Cont Current of 135 A;
- Maximum burst discharge rate of 150C;
- Max Burst Current of 270 A;
- JST-XH charging plug;
- XT60 discharge (drone) plug;
- Net Weight: 198 grams;
- Dimensions: 90.30 x 33.27 x 29.90 mm (L W H).

Battery came about half charged (48%), which is recommended for storing. I measured 15.34V on the XT60 plug. Cell 1 – 3.83V, Cell 2 – 3.845, Cell 3 – 3.83V and Cell 4 – 3.83V.

Is it worth to upgrade from 1300mAh to 1800mAh?

In order to make a fair compassion I used same charger (SkyRC iMAX B6 Mini) with same settings. Both batteries I used for the test had less than 10 charging cycles.

Firstly, I fully discharged both batteries, rest them for 1 hour, then charged them up at 0.5 A. As you can see in the comparison table bellow, the R-Line 95C finished the discharge process more balanced. At the end of charging, both batteries were well balanced. The two batteries remained cold during the charge.

In order to test how these two behave in the real world I used my Kopis 1 racing drone. I tried to fly them with similar amount of throttle in order to get the most accurate results.

As I'm not a Pro racing pilot, I haven't noticed significant performance dropping from 95C to 75C while flying at top speed. Also, the extra weight doesn't seem to be an issue for the 2450KV brush-less motors. Frankly, it's hard to get an objective measurement of true "C" rating without professional tools.

 

I ended my test flights when OSD shown 14 volts (~ 3.5V/cell). While my flight with the 1300 mAh LiPo lasted about 5 minutes, the one with the Tattu 4s 1800 mah ended after almost 7 minutes. Unfortunately, I forgot home my infrared thermometer and I can’t confirm if motors and ESCs became hotter after the longer flight.

Those who need extra flight time for their FPV racing drone, this Tattu 1800 mAh LiPo can be ordered from EU and USA (delivery from both, EU and US, is available). Now genstattu Black Friday Sale coming soon. Begins 22nd and ends 30st Nov. Don’t miss! More the biggest sale is HERE

Pros

- Well packed, with included plug protector;

- Aluminium envelope for good heat dissipation;

Cons:

- Suitable only for larger FPV drones (210mm and up).
