The coaxials are not real helicopters because it has 2 smaller motors driving 2 counter spinning rotors. I think the setup waste power and you also need a extra motor at the end to push the thing around. I would rather have those that has only 1 rotor that can fly out door, but of course even harder to fly.

the 4ch ones do not need extra motor at the end anymore.

are they real cheap in HK? I'm bidding one on eBay... The toy-ish ones are ~20-60.

ACC-HE 發表於 2010-8-31 22:36

But still 2 motors for the 2 rotors and therefore I think still waste power on the extra weight and gear. Also 4Ch is more expensive too.

I saw one in LD for $99, but it is still a 3Ch.

so you fly a Fixed Pitch / Collective Pitch?

作者: saotome 時間: 2010-9-1 10:41

Hey ACC-HE you wanna get one?

I have a 4ch coaxial ultra micro chopper which I only flew a couple times. It's true 4-channel just like the bigger ones and this one is only at your palm's length. So you can fly in the living room. Lemme know if you are interested.

FYI I fly everything from FP and CP heli to 4' A380 electric jet

作者: saotome 時間: 2010-9-3 10:46

Intro to heli flying:

Please note that learning to fly a helicopter is a staging process, you need to go thru the following basics:
- Hover (tail facing yourself)
- Hover (sides facing yourself)
- Hover (nose-in)
- Forward flight
- Backward flight

It can be a very lengthy process so take your time, and you WILL crash a lot. It's best to do it in a simulator. Some people (like me) will find it too boring to complete the training only in simulator, so it's okay to pick a stable, durable heli to practice.

For complete newbie, I agree with BarF1 that they should start with coaxial heli. Coaxial helis have the natural ability to stabilize themselves when you don't give any input, which makes it perfect for inexperienced pilot.

to be continued

作者: ACC-HE 時間: 2010-9-3 10:49

what skills shall one learn with Coaxial, in order to 'graduate' to flying FP?

作者: saotome 時間: 2010-9-3 11:02

Almost virtually all coaxials in the market are fixed pitched and they are not designed to fly outdoor or in any environment with air current. Some wouldn't even handle the slightest breeze.

Eflight MCX is a nice little coaxial with precise controls and feel. It's operating with 2.4Ghz radio makes it very tolerant with interference. On the other hand it leaves a big bite in your wallet, while I think it's an overkill to have 2.4Ghz as the heli is mostly flying within 10' radius around the pilot in the living room.

IMHO, any real 4 channel (Elevator, Aileron, throttle and rudder) heli will do the job, regardless of the frequency it's operating in (IR, RF or 2.4Ghz digital). sub-Micro heli is preferrable because it's very light and it does not cause much damage when you crash.

to be continued

本帖最後由 ACC-HE 於 2010-9-3 11:11 編輯

I had an IR one, kindda sucks 'cause sometimes when it goes behind something, line of sight is gone, and it'll drop or fly into things with blades spinning non-stop.

At first I was looking at G.T. 5888, but I like MCX2 much better.

[youtube]2blE32Ng6DI[/youtube]

The cheapest I can find is $119 + tax locally. I can't believe they don't include an AC/DC adapter at that price though...

作者: saotome 時間: 2010-9-3 11:22

Once you are able to do the basic maneuvers; allow me to repeat again:
- Hover (tail facing yourself)
- Hover (sides facing yourself)
- Hover (nose-in)
- Forward flight
- Backward flight

You can then upgrade to a single rotor heli once you can do the above with ease. Be warned, I know you pilot-wannabes want to get cocky and go for those flashy sub-micro single rotor, fixed pitch heli such as the Walkera 4#3, and my advice to you is: DON'T EVEN THINK ABOUT IT. They are in fact experts' toy and not for the faint of heart. They are super twitchy, super fast and you will end up with a super repair bill.

Single rotor heli does not "stabilize itself" as much, comparing to coaxial, when you give no input, thus you must be on top of it at almost all time. Bigger helis are more stable and easier to fly than smaller ones, and you should be looking at models with simpler structure, fewer moving parts such as the Walkera #4 or Compy FP. Walkera CB100 is good too but it has some metal parts and they tend to bend instead of breaking in crashes, which affect flying performance.

I strongly suggest to get yourself a good set of simulator before moving on. Again you should practice the above drills with your simulator or your newly acquired single rotor heli and make sure you can perform them comfortably.

to be continued

作者: saotome 時間: 2010-9-3 11:49

ACC-HE: Yes the MCX is the best choice if money is no object.

Let's backtrack a little; as I stated earlier, IR is okay for sub-micro coaxial that flies in the living room. Remember the idea of having a sub-micro heli is to train your reflex and finger muscle, while minimizing the cost of repair.

To get your started, I would suggest to get a cheapo IR heli with true 4 channel. and a battery charger like this:
http://www.dealextreme.com/details.dx/sku.12618

You want a dedicated, good charger because the one that comes with the remote (transmitter) tend to put too much current on the battery. And a good charger will continue serving you well as you move on from heli to heli.

I can talk about simulator and transmitter later if you just want to get airborn at this moment.

作者: ACC-HE 時間: 2010-9-3 11:57

I was thinking to myself, why waste the $20-60 when I know I'm going to get the ~$100 anyway? if I go straight to ~$100, then it is like having $20-60 off.

Still coaxial, but I think I'll enjoy it more. And with the controller, I can buy BNF models later cheaper.

Digital Balance Charger and Discharger? what do they do? Really needed? MCX2 come with a charger with AC/DC port, just no AC/DC adapter.

作者: saotome 時間: 2010-9-3 12:30

ACC-HE: I know exactly how you feel, because I was once in your shoes.

Of course you can blow all your budget on the MCX. However, please understand that heli flying is *NOT* a one-off thing but more like a staging process. The MCX is a good heli but you will grow out of it in very short time. So you should conserve your resources and get something cheap yet functional to start with, and something you will be using for a long time (e.g. good charger) regardless of the heli you will be switching to.

作者: saotome 時間: 2010-9-3 12:36

Don't waste your buying power on a coaxial, cuz you will want to blow your hard earned dolloars on something like this later on

作者: ACC-HE 時間: 2010-9-3 12:40

Thanks saotome. Is your A380 finished? Is flying planes more fun? or helicopters?

作者: saotome 時間: 2010-9-3 12:48

You are more than welcome ACC-HE.
Yes the A380 will have her maiden flight (again, since the converting from the pusher prototype from last year) this weekend.

They are both fun and they are very different animal. Heli is good flying in smaller space in relative terms while planes can handle more wind. I mostly fly plane now because they look better in the air, they are cheaper to build, to maintain and to repair.

作者: ACC-HE 時間: 2010-9-3 14:14

cool, are you inviting LYK's to your maiden flight event?

MsR are selling like crazy ... nine eagle's coaxial flies exactly like the mcx2 .. but a lot cheaper ...
So ... get a nine eagle coaxial to learn how to fly ... so the initial start up cost is lower.. then go get a MsR or SR 120 ... ( I cant wait to get my hand on a 120 to try) ...

Try to stay away walkera, from what I've seen, part support is scarce. While its pretty easy to get nine eagle and blade parts ...

ACC-HE: Sounds like you've been making good progress, how's your nose-in hover doing? ;)

CB100 is actually a variant of 4#3b, yes it is nice but again I have to stress that it's another expert's toy - you will always need to repair and to replace something in every crash. Oh the other hand, the 4# series are of course a lot more precise and provides more performance than the 9 eagle.

i'm flying at full speed, tried to do a tight 8, then hit the wall. Pick it up, and fly again, haha...

I'm not too sure what's nose-in exactly yet.

I see, ya, usually i'm fine with that, but since the NE Solo Pro is not that stable even when proper trimmed, I just fly it around. More fun then just hovering.

作者: saotome 時間: 2010-9-8 15:45

It is imperative for RC heli pilot to be able to hover in all orientation. This is especially important as hovering isn't just the foundation but also safety measure; when you move up to bigger and more powerful heli, you must be on top of it at all time or you could seriously hurt or even kill someone if not sabotage the surroundings.

So, are you ready to get your first simulator now? ;)

作者: ACC-HE 時間: 2010-9-8 20:14

Seems like none of the RTF tx can use with a simulator though... correct?

作者: BarF1 時間: 2010-9-9 07:32

The point of hovering is to stablize a bird, single rotor wont sit there like a coaxial ... so it will require inputs ...

Get the Phoenix ... It comes with a DX5e ... inexpensive and very fun ...

back in the days when there is no gyro sensors.... controlling it needs 1000% concentration...it was pain in the ass that i have to make constant adjustment to the wind..

but i am still afraid the paddles like the 4#6s.... i always afraid that the paddle is not aligned well.... its is how i crashed my last one... i think.. the paddle went loose.. and i am not know how is at the right angle..
