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.

How to buy a good red & green laser pointer as your Christmas gift?

Still thinking about what you should buy for your friends since Christmas is just only less than two weeks? Here you can take a few minutes to look for a laser pointer which is also a good choice for you:

More than thousands of laser pointers in the market, well, how to choose the one with high quality and will work best for your needs are more important.


Most of the laser pointers we can see are come with 5-heads, or some only have one head. If you buy this kind of laser pointer, you may need to make sure that what material does the head of the laser pointer made from. Metal laser pointer is more durable than the plastic heads anyway. Other elements you should take into consideration are that the battery of the laser pointer, if a laser pointer takes AAA batteries, then that item is said made of good quality.

While for the beam of the laser pointer, we can see that there are red beam, green beam and multi beam laser pointers. Also some of them are come with multi-color lasers like 3 in 1, 4 in 1 or 5 in 1 laser pointers, these beams can change by pressing the relative buttons.

Except for the above elements, you may also consider the mw rating on the laser pointer. If you are using it in the USA, the laser pointer must be rated less than5mw to be legal to buy and use without a permit and this must be printed on the warning label that goes on the laser pointer. Also lasers with power higher than 5mw can be very dangerous and are not safe to use without special safety equipment and taking special precautions. So you should make sure that the laser pointers you are going to purchase are legal and safe.

For these laser pointers, if you are a new user, you must read carefully about the safety specification, do not put that in the place where Children can touch.
