I modified a Double Horse 9104 to a 4 channel WL V913 by using the WL V913 PCB board, a 2nd stock 9104 servo, DH 9117 swash plate, and using my WL V911 controller to fly it. It flys for about 5 minutes on a stock battery. Left turns are nice tight and small, while right turns are wide and big.

Here is a video of the maiden flight still setting it up with wide big right turn crash into tree:

Last month, I crashed my Hawkspy LT-711 and the lower gear that turns the upperset of blades came loose. I had to take the LT-711 a part to tighten the lower gear back to the shaft. I had also found a bearing laying on the floor after the fix.

Then the lower gear kept coming loose and not staying tightened to the shaft.

I took the LT-711 apart again and looked at the area where both the upper and lower gears are on both shafts. I noticed that on the bottom side of the upper gear there is a hole for a bearing. I put the bearing I found (laying on the floor after the fix) in that hole on the bottom side of the upper gear. Put the LT-711 back together tightening the lower gear to the shaft. The lower gear no longer comes loose from the shaft.

So if your LT-711 lower gear won't stay tightened to the blade turning shaft, take it apart and verify that the bearing is still in place on the bottom side of the upper gear as this helps hold the shaft turned by the lower gear in position and keeps it from wobbling around that loosens the lower gear blade.

Followup to my May 2013 review of the Walkera Mini CP:
It is still working great and is a alot of fun. The only thing that has had a problem is the tail rotor guard has broken off. I took off a solid tail rotor guard from another small helicopter and put it on the tail boom of my Mini CP.

While I have flown 3 channel coaxial helicopters and 4 channel single rotor fixed pitch (FP) helicopters for more than 1 year, I am a beginner to 6 channel collective pitch (CP) helicopters. My first 6 channel CP helicopter is 450 size and not a good size for a begginer to start with. I have a small backyard and needed a smaller durable CP helicopter to practice with so I just bought a Walkera Mini CP Ready to Fly last week. I enjoyed the Walkera Mini CP so much I just bought a Walkera Master CP Ready to Fly this week. The Master CP is 200 size, it is bigger than the Double Horse 9116 and smaller than the Double Horse 9104.

Stock out of the box coming with 1 battery and a DEVO 7 controller, I charged the battery up and scanned over the documentation that came with the Master CP.

With the first charged battery and no adjustments, I turned the Mix switch to position 0 and the D/R swith to position 0. No trim adjustments were needed on the transmitter controller to get it to hover. As usual with single rotor helicopters, it flys a little left sideways when taking off.

It flys exactly like the Mini CP and is built with the same durable materials as the Mini CP. So with this Master CP I will get the pratice I want with a durable medium 200 size 6 channel CP helicopter to help me be able in the future to fly my 450 size 6 channel CP helicopter.

For beginners of 6 channel helicopters before buying the Master CP, I would first recommend buying a small 4 channel...Continue Reading

Here is the path I took going from 4 channel single rotor fixed pitch helis to 6 channel single rotor collective pitch helis.

Started with 4 channel helicopters:
It is good to be familiar with a 4 channel single rotor helicopter first. I have 3 different size 4 channel helicopters: WL V911 (small), Double Horse 9116 (medium), and MJX F645 F45 (large). The WL V911 is a inexpensive good small 4 channel helicopter to learn single rotor helicopters.

Intermediate step before going to 6 channel helicopters:
While flying 4 channel FP helis require more joystick moves to fly them than 3 channel coaxial helis, they still don't require as much joystick moves to fly them as 6 channel CP helis. I was interested in learning quadcopters also and bought a inexpensive small 4 channel Syma X1 Spacecraft quadcopter. The Syma X1 quadcopter requires more joysick moves to fly it and is much closer to flying a 6 channel CP heli than flying a 4 channel FP heli is like flying a 6 channel CP heli. I recommend the Spacecraft model of the Syma X1 because it is easier to look at it while flying and determine the orientation of front and back of the quadcopter.

Beginning to fly 6 channel CP helis:
Start with a small helicopter first. My first 6 channel CP was a 450 size and almost every time I crashed it, something was damaged and broken. So my second 6 channel CP is the Walkera Mini CP. It requires the same amout of joystick movements to fly it as my 450 size CP heli. The Mini CP is small and durable as I have crashed it several times with no damage yet.
Learn to hover first. I have a small backyard and am learning to hover the Mini CP first. I'm getting pretty good at hovering and keeping it in a small area. Soon I'll start flying it around.

My first 6 channel CP helicopter is 450 size and not a good size for a begginer to start with. I have a small backyard and needed a small CP helicopter to practice with so I just bought a Walkera Mini CP.

Stock out of the box coming with 2 batteries and a DEVO 7E controller, I charged both batteries up and scanned over the documentation that came with the Mini CP.

With the first charged battery flying in a 3+MPH wind, I adjusted the trim on the transmitter controller to get it to hover. As usual with single rotor helicopters, it flys to the left sideways when taking off. The trim adjustments required were a slight forward movement and about half way to the right sidways movement, perhaps because of the wind. When I get a calm day, I'll try to make adjustments to the servo pushrods that connect to the swashplate, if needed.

The second charged battery, I got some flying in and only crashed it 2 or 3 times. See the video below. It performs as I wanted and will give me the practice I need to be able to fly my 450 size CP helicopter. Both these 6 channel CP helicopters I have require alot of joystick movements to keep them flying compared to 4 channel helicopters.

Perhaps we should try not to let the news media call our fun hobby aircraft with the name drones. There appears to be a negative public perception of military drones and law enforcement drones and the media seems to be putting our fun hobby aircraft in the same category with them. What do you think and is there anything we hobbyist can do about it?

I already owned a couple of 3 channel Double Horse 9104 and a 4 channel Double Horse 9116. The Double Horse 9117 uses the same controller as the 9116. So all I had to buy was the 9117 swashplate and 9117 4 channel PCB board to convert a 9104 to a 9117 which cost about $30US. I moved the servo from another 9104 over to this heli to finish the 4 channel conversion.

After converting the 9104 to 9117, I took it out for some flying. There was a major problem with the battery power for the 9117 PCB board. The 9117 would not stay up in the air, it would lose power like the battery was running down and lower to the ground or very low close to the ground. I flew the 9117 several times with a full battery charge. The power problems happened every battery charge that I flew it. I read posts by others on this forum that said they used more powerful batteries and it burned up the motor or PCB board so I did not try a different battery.

The power issue was a major disappointment and I was happy I did not pay the full price to buy a 9117. I converted it back to the 3 channel 9104 and there are no power problems. It appears the power problem was with the 4 channel 9117 PCB board.

All 3 helicopters are attractive, powerful for 3 channel coaxial helicopters, and about the same size. The DH 9053 is between the size of the S033G (slightly larger) and S031G (slightly smaller).

The decision as to which one you will enjoy depends on whether you like to perform maintenance or like doing no maintenance.

After almost a year of experince with all 3 of these helicopters, the Syma S033G and the Syma S031 do not need maintenance, while the Double Horse 9053 requires maintenance.

The maintenance on the DH 9053 started with needing a modification of flipping over upside down the blade grip of the lower set of main rotor blades. This was to increase the distance between the upper set of blades and lower set of blades to reduce/eliminate blade strikes. It was frustrating to be flying and have a blade strike that caused the DH 9053 to fall to the ground and result in damage depending on how high it fell from. It was frustrating to have a crash and damage that was not a pilot error but a design error until the lower blade grip modification was made. After the modification to the lower blade grip, the maintenance was freqent replacement or repair of the lower blade grip.

Both the Syma S033G and Syma S031 have been enjoyable and flown great with no problems and no maintenance needed.

This is a flying video of my second time to fly a MJX F645 F45 helicopter. It is stock with no mods. I was flying in a small area and there was a 5+ mph wind blowing so it is being blown around a little. Video ends with crash of helicopter being blown into a small tree or perhaps pilot error No damage to the helicopter.

I bought the assembled ready-to-fly (RTF) Aerosky quadcopter as my second quadcopter. If you have never flown a quadcopter buy a small less expensive quadcopter to learn how to fly with first. I bought the Syma X1 to learn with first.

The Aerosky I bought came preassembled RTF except I had to put on the propellers and put the velcro tape strip on the side of the battery. Also it did not come with a wall power adapter, it has to be purchased seperately. It comes with a power adapter with 2 aligator clips: one red clip and one black clip.

The instructions are very bad, only 1 big fold out sheet. However, there is enough information that I managed to figure out how to operate it.

It flys well and is very fun.

I crashed it hard a couple of times and it appears very durable. I bent a couple of the plastic propellers and just bent them back into shape.

Pros:
Flys well, fast, and fun
Durable

Cons:
Instruction manual is bad but enough information to fly it
Spare parts, I'm not sure where to find Aerosky quadcopter specific spare parts but should be able to find generic functional spare parts
Does not come with a wall power adapter, it has to be purchased seperately. It comes with a power adapter with 2 aligator clips: one red clip and one black clip.

The instructions I figured out:
How to start flying it:
1. Turn on the controller then plug in the quadcopter battery. Not sure if the order matters.
2. Unlock the propeller blades by moving the left stick to the lower right corner position and hold it there (about 2 seconds) until the propellers start turning slowly
3. Start flying

How to stop flying it, if crash, the battery runs down, etc.:
1. Lock the propeller blades by moving the left stick to the lower left corner position and hold it there (about 2 seconds) until the propellers stop turning

I wanted to buy an Aerosky quadcopter but, I have never flown a quadcopter. So I bought a less expensive Syma X1 Spacecraft quadcopter to learn how to fly a quadcopter.

The Syma X1 flys well but if you have never flow a quadcopter before it take a few minutes to get use to the flying characterics of a quadcopter. It flys like a 4 channel or 6 channel helicopter and the controller has the left/right sideways flying on the stick with the forward/backward movement and the left/right turns on the stick with the up/down movement.

It is durable as I crashed it hard a few times while I was learning to fly it. Fly it outdoors while learning to fly it. It can fly fast so I would not try to fly it in doors until you are very good at controlling it.

There is no on/off switch. When you slide the battery into place it connects and the power comes on. Next you turn on the transmitter controller.

I also taped a keychain video camera centered on top of it to get some onboard aerial video from it. Worked great.

Pros:
Durable
Easy to fly
Good to learn to fly quadcopters with before buying a bigger more expensive one.

Cons:
No on/off switch

Have fun flying!

Here is the path I took going from 3 channel coaxial helis to 4 channel single rotor fixed pitched helis.

Started with 3 channel coaxial helis:
Flying 3 channel coaxial helis is fun and they are easy to fly. I have several models in size from 8 inches up to 36 inches. The coaxial helis float off when the wind blows, you have to land them and go get them.

Intermediate step before going to 4 channel helis:
As I began researching 4 channel helis, I came across 3 channel single rotor helis with a vertical tail rotor: the Double Horse 9104 and the Double Horse 9100. Due to the larger size, I picked the 9104. It is fun to fly and flies in winds up to 5mph. It flies faster foward than the coaxial helis so it requires a larger area to fly it. The vertical tail rotor swings the tail end of the heli right or left quickly. It is more challenging to fly than the coaxial helis so it helped having experience flying the coaxial helis before flying the 9104.

Beginning to fly 4 channel helis:
As I researched the 4 channel helis, I narrowed it down to the Double Horse 9116 and the V911. I like to get aerial video from my helis by putting a video camera on them so I chose the Double Horse 9116 as it is bigger than the V911. There is good 9116 info here on RCGroups in the blog by “stormforce” http://www.rcgroups.com/forums/member.php?u=384746

4 channel controller different than 3 channel controller:
The 4 channel transmitter control has a switchable setting from Mode...Continue Reading

I removed the screw from the bottom of the canopy connecting it to the bottom of the frame. This has helped to reduce the Double Horse canopy breaks.

Have fun flying

Here is my beginner's review of the stock (no mods) 3 channel Double Horse 9104.

A little about my experience with helis:
I started flying 3 channel coaxial helicopters around the first of February 2012. In March 2012 I bought a 3 channel Double Horse 9104 and a 4 channel Double Horse 9116. This month of April 2012, I just bought a 6 channel 450 and am learning 6 channel helis now also. Helis are great fun and addictive.

The Double Horse 9104
The 9104 takes off to the right. See my flight video below. Be aware of it and watch out what is to the side when taking off. Once it is up start flying it forward. This is something I can live with for an inexpensive 3 channel single rotor heli.

It flys great in up to a 5mph wind. At greater than 5mph winds, it begins to drift off like a 3 channel coaxial heli.

It flys leaning to the right but it flys straight just with a slight lean to the right side. Again not a big deal to me for an inexpensive heli.

(added 2012/04/15 1:19pm) The durability is very good. The blades, canopy, and landing skids are very flexible. I removed the screw from the bottom of the canopy to help reduce canopy breaks also.

(added 2012/04/15 3:51pm) It flies faster than a coaxial heli and needs more space. It needs to be flown in a field and not a small back yard.

Pros:
Inexpensive
Flys great in up to a 5 mph wind
Durable (added 2012/04/15 1:19pm)

Cons:
Takes off going to the right
In greater than a 5mph wind, it...Continue Reading
