Tattu 1550 4s 95C review

Today we have the latest 4s offering from Tattu’s R-Line series of high performance fpv racer batteries.
Tattu R-Line 1550mah 4S 95CI’m already a huge fan of Tattu batteries for my daily drivers for a few reasons but mainly because they are quality that I can count on. What is written on the label is what you get and they can take more abuse than a ginger step-child with-out getting all puffy and dangerous.

Are quality high c-rated lipo’s really that important?
Hell yes they are, whether you are flying competitively or just for sport there is huge difference and while I am Not a battery nerd with a detailed breakdown… I can confidently tell you that you will feel every bit of power when its delivered that much faster. Check out this article on what’s in a C rating to understand exactly it means.
These R-Line go Hard!
After 3 days with my Furibee X215 I’m not going back, not to a regular non R-line tattu or anything else! These R-line go hard and not just with a massive punch right outta the gate. You get the full rip almost until the end of the battery, no joke 3-4 minutes in they still feel fresh off the charger. At the end of each run, my temps are noticeably lower as I’m just not stressing the battery further than its limits halfway into a fight to keep up my flow.
Would I recommend the Tattu R-Line 1550mah 4S 95C?
While more expensive than your average performance lipo, the solid c rating of the Tattu R-Line 1550mah 4S 95C is well worth the extra cash. These batteries have that punch you are looking for from a brand that we trust.

Turnigy graphene review: can increase flight time?

Why so many people looking forward to it and is Turnigy graphene lipo battery really can increase flight time for quadcopter? Today, I make a article about Turnigy graphene review for helping you to know what's the graphene battery and its performance.


What is the graphene lipo battery?

Graphene batteries is Newly developed a kind of new energy battery, which the use of lithium ion in graphene quickly a large number of shuttle between the surface and the electrode movement features.

There are at less 3 advantages of the graphene lipo battery as below:

  • High capacity energy storage
  • Shorten charging times
  • Longer cycle
  • Less weight
  • More cheaper

Turnigy graphene review 1300mah

 Turnigy graphene review

As above image you see, Typically I see the end temperature around 130F to 140F. Again, the Turnigy graphene pack performed much better than a standard LiPo. After more than 80% discharge at 27A it was barely warm at 108.5F! 


Can turnigy graphene increase flight time for quadcopter? Yes, but not exactly. In fact, according to our survey, graphene material just assisted as additives to increase the performance of lipo battery. So far, they are all more or less good for increasing the performance.

Gradually along with the mass production and large size problem, the industrialization application of graphene is speeding up, based on the existing research results, the commercial application of the first field would be on a mobile device, aerospace, new energy battery and drone field.

Now, there are many brands of graphene battery in the market such as Turnigy, Arris, Grazepony etc. Which one would you like to purchase? Please leave your messages on here, if you have any questions about the graphene battery.

Fisheye lens for UAV

How to make your UAV have wider FOV? You should make a change of your lens of your UAV. 
I ever purchased some kinds of fisheye lens to replace the original onein our UAV, but the result is not satisfactory, the FOV isn't wide enough for me, and I found the image is blur, especially the edge. 
Last month, I purchased a 1.05mm fisheye lens  SA-010528FEB  from Fuzhou Siaon Optoelectronic Technology Co., Ltd.
The lens is very goods, with 245°x245°x245° FOV, 10MP resolution, 1/2.3" format.
I try it in my UAV. the image is better than before. If you want to make a change of your lens in UAV, you could make a try of the fisheye lens from Fuzhou Siaon.

HK 450 GT beginner setup

Hey all

You´d like to join the huge rc heli community but don´t know how to start and what equipment you need? I hope to help you doing first steps on my own experience.

Forget all coaxial helicopters! Start with the 450 size one :) If you´ve got a lot of unneeded dollars you can buy a T-Rex and then (after crash) always expensive genuine parts… But I wouldnt…

My first idea was to buy a second hand heli… Forget it! It will be just trouble with it! A helicopter is a quite expendable toy and you will surely need to replace most parts of used one! For a beginner is a HK450 heli actually a very attractive choice. Replacement parts are cheep, T-Rex parts feet also if one wants to exchange something to get more precisious helicopter reaction. Now here is the best beginner setup! I crashed my first heli seveal times and no one servo was damaged for example!

Just order everything by Hobbyking (all links are to international warehouse but you can choose your favorite wh on hk webstore. Dont forget, for different warehouses you have to place different orders!):

All this parts you need to get your heli taken off. Of course you need a transmitter and a receiver, too. I use e.g. Hitech Aurora 9 with Optima 6 (or 7, or 9)

A little bit replacement parts statistics after some crashes could be helpfull for you:

Main shaft 4
Feathering shaft 4
Bearing 5x11x5 5
Stabilizer bar 5
Bearing 4x8x3 2
Bearing 4x7x2,5 2
Skid pipe 2
Linkage rod eye 3
Vertical tail fin 1
Main gear 1
Screw M2x12 3
Tail boom 3
Horizontalfin band 1
Landing skid 1
Landeschlitten 2
Main blade (pairs) 6
Tail support rod 1
Chassis 1

So it is recommended you buy some more replacement parts to get uninterrupted flying fun!

Mounting instructions of this helicopter you will surely find on youtube.

Hope this setup will be helpfull for you! Enjoy it!

AGM 30cc Engine Could be Option for RC Aircrafts Wingspan Ranging from 72-74 Inches

Released from AGM DISTIBUTOR LLC, the AGM30cc gasoline engine shows a great performance when installed on different model RC airplanes. More than thousands RC players have bought this engine from AGM’s online stores.

AGM 30cc gasoline engine 


While there are still some players who do not understand well about the specification and features of the AGM30cc engine, here I would like to make a small introduction about that:

AGM 30cc engine is a small gasoline engine specially designed for RC model airplanes, with the displacement of 30cc, this engine can get to a horsepower of 3.7hp/8500rpm and the idle speed is able to reach even 1600rpm/min. Using a walbro carburetor and rear carb, auto advancing electronic ignition, and CM6 style spark plug, this engine can be installed on RC airplanes wingspan ranging 72-74 inches.


For example, AGM30cc is suitable for the Extreme Flight 70" Extra 300 EXP ARF, and there are also some users who have installed them on other airplanes to have it worked perfectly. Like the 80" Sundowner, Precedent T240, Super Cub, RCPilot 3D Trainer 90, Hangar 9 Quarter Scale Super Cub, Hanger 9 P47 D-1 and more…


To know whether an  airplane gasoline engine is suitable for your model airplane, you should first make sure that the weight and size of the airplane, and then use the probable prop to support the airplane fly in the air. Of course, the diameter and stroke of the gasoline engine, the ratio of compression and lubricating capacity are always important. Meanwhile, the weight of the engine cannot be too heavy to affect the airplane’s performance.


Normally, we recommend RC players to choose the engine with strong power and match well with their model RC airplane to get the best experience. And the quality of the engine also should be great and fight with the strong wind and other elements to make your flying steady and strong. For most of RC hobbyists, AGM30cc gasoline engine no doubt to be a good choice due to it combined the best advantages and also affordable for them.
