This review is from: 38cm Double Horse 9116 2.4GHz 4CH 4 Channel RC Single Blade Helicopter Gyro Big 450 Size (COLORS MAY VARY) (Toy)
Someone already wrote a really nice review of this copter so I'll keep this fairly short. First and foremost, if you think you know how to fly helicopters from flying 3ch coaxial helicopters, you don't. Although they have provided you with some of the physics of rotary flight, they've also provided you with a huge comfort level in that they are able to hover continuously. Forget most of that with this one.

A 4ch single rotor is getting the user closer to collective pitch flying will still providing a greater degree of safety via being able to hover for brief periods and with some input from the flyer. More challenging but a lot more fund when you've mastered it. This is a great beginner copter for someone who hopes to progress to 6ch CP and likes to fly outdoors. Most coaxials do very poorly in the wind, this does better. Still not great but able to be confidently flown in 5mph breezes.

The copter itself is very well made IMO. Real hobbyists will probably tell you differently but for the price, it really can't be beat. The transmitter that comes with it has far more features than anything else in this price range with the ability to fly in two modes (slow/fast) that changes all the controls. You can even go in under individual controls and get throw rates and percentages to soften the initial flying - make all those adjustments under the slow setting and use that to train yourself. Don't get impatient trying to figure out all the ideal settings for flying - it took me three battery charges to get it right and even then, I still have to use the minor trim buttons to get it perfect for each flight.

Suggestions: Buy the spare parts kit, either on here or from and overseas supplier and buy an extra tail boom/motor combo as the tail motors are not real durable from what I've read. Personally, I bought a DH 9100 here on Amazon for $45 shipped to use as a parts copter - about 85% of the parts are identical to the 9116 plus you'll get a spare battery. It ends up being about the same as what you'd get from various vendors and plus you'll have all those little screws leftover when you're done and they are extremely nice to have.

Double Horse is never going to produce the highest quality on the market. If you want a more well built unit, get a Walkera but if you think you're eventually going to progress to 6ch, get this and save your big money for the next step up. Durability of this unit hasn't been proven yet, might even be described as a little sketchy if you read the radio control forums. I think some of that is unrealistic expectations that it should fly perfectly right out of the box like your coaxial did - isn't going to happen.

One very strong suggestion - always buy this from Amazon where Amazon is actually doing the fulfillment. Most vendors not selling on Amazon will not take returns unless it's absolutely DOA and you call within a day of it being delivered, even then some will assume it worked and you crashed it and may not be as accommodating as you would like. Amazon has basically a no questions asked return policy where if it is defective, they pay return shipping and the refund is very quick.

UPDATE: Having now flown this copter for many hours, my initial impression remains - great value for the money. I have since learned how to make some mechanical adjustments that allow it fly much better and hover almost hands off. If you join the rcgroupsDOTcom forum, you will find a long thread dedicated to this copter and how to make it fly better than it does out of the box. Basically, when you get into 4ch and above flying, there is no such thing as ready to fly perfectly, they will all need some adjustments. Playing with the sub-menus on the controller really makes a difference in training as you can slowly increase various features as your skills improve and then finally go into the "quick" mode where everything is preset to 100% (although can still be changed).

If you're on the fence about this copter, get it. Unless you are an accomplished flyer already, this will be challenging enough to be be fun and durable enough to put up with amateur mistakes. I've flow it into the house, crashed it onto pavement and even got it trapped under a car upon landing. The blades are unbelievably strong because they have taken a beating. Now that I'm a bit more accomplished, I can see one set of blades lasting for the life of the copter.

Do yourself a favor and order a 900mah battery to replace the one that comes with it. Increased flight times will be the result and it fits perfectly in the existing battery cradle. Little bit heavier so you may have to dial in some forward trim to offset it but that's no big deal.

I completely agree with your review. Also thanks for the updated tips. I would also add that if you plan on getting more, better quality batteries you might consider investing in a quality charger. I've got the "BlitzRCWorks xr6ac pro power." Chargers like this prevent damage to batteries, decrease charging time, and increase the life of the battery. Also, that charger I've mention is capable of charging the stock battery in about 10 minutes.

Great review also! I ordered me one a day ago and can't wait to fly it. I'm very new to this RC helicopter hobby but always wanted to fly one ever since I was a kid and they weren't even invented. (I'm a 50 year old kid)... I did order an extra battery because I want more flight time. I ordered what Amazon suggested for a replacement battery but now wonder if it's the correct one for my copter. I ordered Replacement 7.4V Li-ion Battery For New Double Horse 9100 "Hover" 3-Channel Sports R/C Helicopter #9100-23. It has a different helicopter model number than the one I ordered however it has the same specs as the original so it will work won't it? Hate to think I'll have to send it back as soon as I get it but I looked everywhere on the Internet and basically could find no clear answer except links kept coming back to the one battery I ordered. Thanks again with any info or suggestions. Keep writing honest and accurate reviews because people like me really appreciate them and respect them.
