why is is that?
 
you have to fly ur cx2 when theres absolutely no wind isnt there something we can do
to fly it in a lil bit of wind?<input type="hidden" id="gwProxy"><!Session data></input><input type="hidden" id="jsProxy" onclick="jsCall();" /><div id="refHTML"></div>

RE: why is is that?
 
it's because of how it's made. you can try and move the linkage on the servo horns out farther, this will give you more throw. just be careful and check that you don't have any binding issues when your done. if your really looking to move up, check out some fp heli's. something like a blade msr or the new blade sr 120 when it comes out. i fly mine little msr in some wind all the time. the msr has some longer ball links on the swash plate that you can move the linkage to, and you will get more throw. making it faster

what about the blade sr wouldnt that be good?<input id="gwProxy" type="hidden"><!Session data></input><input onclick="jsCall();" id="jsProxy" type="hidden"/><div id="refHTML"></div>

RE: why is is that?
 
yes. it's ok. i have one. if you think your ready for it, go ahead. it's alot harder than a cx or msr. those will hover pretty much by themselves. a sr or any cp heli won't, you have to fly them

RE: why is is that?
 
Have you ever flown a CP (collective pitch) heli before?

If not i suggest you take the 200 you gonna spend on the SR and buy a flight sim. or at the least buy a cheap sim and the SR. I strongly suggest if you have never flown a cp before to get some experince before you jump into a CP and crash it your 1st flight. When i first started and I am still new only been doing this since last christmas i bought a cheap 20 dollar sim it tought me how to hover some what but then went out and bought Phoenix flight sim and that was well worth it imo. I would not be able to fly my helis if i did not have phoenix flight to teach me.

Another option for you is to wait for the New Blade 120 SR comming out in August made by Eflite. The Blade 120 Sr is just a bigger version of the mSR and can handle more wind then the mSR for outdoor flight.

<input type="hidden" id="gwProxy"><!Session data></input><input type="hidden" id="jsProxy" onclick="jsCall();" />yea i was thinking about that. i mastered the cx2. i like it i have alot of fun with it. but i just wnna try something different in the near future. and why are cp helis so hard to fly?

Hi Flyboycx2,

A coaxial heli (like the CX2) uses the upper and lower blades to counter the turn of the tail that a CP heli experiences. So basically a CP heli requires you to 'be on the sticks' all the time, so to speak. Just a bit more demanding. When you do go to a CP heli, make sure you get one with a good gyro above all else. You'll need it.

Ask away, were here to help.

Buy a SIM and learn all day long.
Then you can jump into a TREX500 right away after hours of practice on the SIM

Flew a TREX500 and I love it, lots more $ than my Blade 400 but it's insanely nice with all the cnc...etc

Flyboycx2 07-27-2010 10:28 PM

RE: why is is that?
 
sounds like i need to get a simulator then. and i was wondering how does the whole positive and negative pitch work. and a trex500 is out of my price range maybe the sr to start with. or the
blade 400 i ALSO READ ABOUT A TREX 250<input type="hidden" id="gwProxy"><!Session data></input><input type="hidden" id="jsProxy" onclick="jsCall();" /><div id="refHTML"></div>

RE: why is is that?
 
After you learn on a SIM the Blade 400 is a great bird because it comes RTF with a DX6i, yes the TREX is a good one, but if you want the mini size like the blade 400 you will need to step up to a TREX 450.

If you want to save the $ for your first CP Heli go Blade 400, I have enjoyed mine as this is what I have been learning on and still am
The bigger the bird the more stable and precise but also the price goes up too :shrug:

<input type="hidden" id="gwProxy"><!Session data></input><input type="hidden" id="jsProxy" onclick="jsCall();" />well as of right now im thinking
about the blade sr. not sure yet

The Blade SR would be a good choice for you: not too big and intimidating and also not too expensive. It will also give you a chance to learn how a CP heli is built and functions.

IMO anything around $300 and above you might as well just get a 450 or 500 class heli.

One thing to include along with your simulator is a pair of training gear for your heli. Look on Horizon's site: [link=http://Here]http://www.horizonhobby.com/Products/Default.aspx?ProdId=EFLH1500[/link] Training gear will help in preventing some tipovers and help in your learning curve.

You may want to look in the classifieds here on RCU and see if anyone is selling a used simulator, could save you some costs. Everyone will have an opinion on which is better, do a search and you should find lots of info.

To answer your question on + and - pitch: simply, positive pitch allows the heli to move upwards (such as take off) whereas negative pitch allows the heli to do inverted manuevers. It just involves changing the angle of the main rotor blades from 0 degrees to + degrees to - degrees while in flight. You'll learn quite a bit when you get your CP heli and begin tinkering with it.

I go straight to a Blade 400 if you can't afford a TREX500 and all the electronics as it will be at Least 2+ times as much $ to get in the air once built.

Flyboycx2 07-28-2010 10:00 PM

RE: why is is that?
 
yes so it seems blade sr and 400 is my best bet. one question why are cp  helis 6 channels?<input id="gwProxy" type="hidden"><!Session data></input><input onclick="jsCall();" id="jsProxy" type="hidden"/><div id="refHTML"></div>

RE: why is is that?
 
Aileron, elevator, throttle, pitch, rudder, and gyro

Jon DesJardins 07-28-2010 10:48 PM

RE: why is is that?
 
Yup, more servos along with the Gyro.

I would skip the SR and go for the Blade 400 if you have SIM time and are confident enough to do so.
The larger the bird the better it handles as the parts are larger and more true.

The TREX with the all CNC upper and Solid Chassis are the most stable I have hovered but also cost a grip more!

RE: why is is that?
 
Skip the SR, it's a waste of time IMHO. If e-flite hadn't crippled it with a tail motor, it would have been a decent trainer. As it is, you'll be spending a lot of time and money replacing burned out motors, or worse, fixing crash damage caused when your tail motor quits in mid-air.

Take the money and buy the simulator, as others have suggested. Then save up a bit more and get a Blade 400, or better yet, a T-Rex 450. The Blade 400 isn't too bad, but it has weak servos, and the ESC and gyro aren't the greatest. By ther time you replace that stuff with better gear, you'll have spent more than you would have getting som,ething better to start with. And by building your own from a kit, you'll have a much easier time repairing damage than if you buy something that's already assembled.

I just flew the CX2 I have for a bit outside at a local park with plenty of space for it, no wind.. Had it going okay, till I pulled back on the stick from full forward.. Blade strikes! Looked like it was having a seizure. Lost the lower blades, the head they attach to lost one of its blade pegs. AND being a fool when i took the screws out of the busted blades to replace them.. I put them on top of the (yeah.....) flight box's parts box. Then proceeded to open the parts box.. flipping the screws into the grass.

Lesson learned... open parts bin first and put screws in one of the bins..

Agreed, the only thing is that when you do crash the Blade 400 will probably be cheaper than the TREX450.
But the TREX450 is nicer hands down.
