Depends on who you are, and who you've asked.

I wouldn't offer it to a beginner, actually. If you're wanting to go three-channel, stick to coaxial design, it's a bit more worked out.

If you're contemplating "Big Boy" copters, SKIP the 3 channel single rotor, and just get one of the low-cost coax 4-channels.


Both of these single-rotor 3-channels have un-used servo mounts. My money is on a simple upgrade kit showing up for them, to make them into "real" copters...

The 9101 is simply a large windbag, you won't have much forward flight power unless you perform some serious tinkering. Just get a fixed pitch helicopter, and take it easy - gradually learn to fly it. First you hover it 5 feet off the ground and trim, then begin flying it 10-15 feet above ground and slowly learn to maneuver it. In the end you'll have a much more responsive helicopter that can dice through mild winds.

If you want a coaxial, you should buy something small like a double horse 9102 which just became available recently - it's around 8 inches long. If you want an outdoor coaxial then I would recommend the MJX T-23 or T-34, MJX helicopters are much better then the large Double Horses.

Just a little experience I have with the few helicopters I've heard about or flown myself.

KB,

Would the included transmitters with any of these helis be capable of being used as 4 channel, if it were possible to install an upgrade for aileron function? What about the receivers?

Anyway, I had posted this video in the 9104 thread you started in the other section.

From the looks of it's high performance flight profile, definitely not a beginner's copter.

It needs ROOM, yes. The head-speed is HIGH.
If this hits you or anything at speed, it will "win".


I think a whole new radio would be req'd to make it four-channel.

But if that came from Double Horse, it could be cost-effective to do...

So it sounds like the 9101 has a "slow" and "fast" setting on the TX to make the tail motor supposedly spin faster for faster forward flight?

I just don't know why these 3-channel heli designers can't come up with a 3-ch that will actually go forward faster if you want it to. A two speed setting on the tail motor sounds like an attempt at that, but they should make that tail motor scream in "fast" mode to get some decent forward speed out of a 3-ch coax.

well they could by just providing a better tail prop with stronger pitch or more surface area which may or may not decrease the lifetime of tail motor but you are still limited cause even with such a mod you are not gonna really move much against 3-4mph constant wind let alone when a gust of 5mph+ comes in, forget it... i've been playing in these kind of breezes outside the whole winter with various props and mods and coaxes are seriously limited on 3ch even worse than 4ch, if you want to move in some winds then you will have to go fp or better yet cp and forget 3ch altogether.

More power leads to porpoising, the copter swings forward and halts, swings forward and halts. A coaxial's un-controlled upper blade set and flybar will always try to return the copter to vertical, and it's a fine balance to get one to fly forwards smoothly.
Also, a coax moving faster is more likely to death roll when attempting to change direction.

If you want to to go forward faster, you have to choose the DH 9104.

Does this one have any advantage over the 9100 other than its size?

No. I consider them equal except for size- I've owned both.

Both will fly to one side constantly, but there are fixes...kinda.
Super-Durable, both of em'.
But neither- can fly "forward fast", because there just isn't enough swash throw.



I had servos to fit the bigger one, and gave the smaller 9100 away so I could focus on the 9104. Update soon on the tinkering.

Incrediblerc: If I can afford to sponsor the forums when I don't even sell copters, maybe you can too?


AND, Are you Computility, the Ebay seller you've linked to?
Somehow, I think this question will be ignored...

Every one of your posts is selling something, isn't it.

Support RCGroups with their affordable advertising programs. I do.

is the forward speed worse then the 9053?
