I used to love flying my CX2s (had 3 of them during last year), but darn it anyway, I could never get them trimmed out to hover hands off for more than a few seconds. Then the dreaded tail drift and other problems related to that weak 3-in-1 / receiver set up would occur as the motors and electronics heated up during flight.
But now I'm having a ball flying the CX2's little brother, the mCX2. With the newer 5-in-1 electronics, this little guy flies hands off right out of the box! No more frustrating tail drift and if you're a good pilot you can fly this thing in a closet without crashing. I also fly a Blade 120 SR but always find myself going back to my coaxials for relaxing indoor winter fun. |

Since you have experience with both... Does the mCX2 get as HOT as the CX2 with the motors? Any problems with the gyro losing "hold" on the 5-in-1 unit if/when it heats up? I ask because I have an mSR, which also has pretty much the same 5-in-1 unit (different T/R mixing, of course) and I think the drive motor for the main rotor is the same as the two in the mCX2. It doesn't get hot at all. Not the motor, battery, etc. In fact, it's barely even noticeably warm to the touch immediately after flying a full pack. I flew four batteries in a row several times yesterday without a "cool down" period in between. No problems at all. Now, my CX2? Those motors get HOT and I have the heat sink installed with Arctic Silver thermal paste and I cut/opened up the canopy for better ventilation.

You simply cannot compare the mcx2 motors to the CX2 motors. With these two helis, you are trying to compare apples and oranges. You flew 4 batteries back to back without any cool down between flights. This is an absolute recipe for disaster on your mcx2 motors even though they don't get hot. Are you aware of the fly time and cool down period for each of your helis? For your families safety, have you been educating yourself on lipo batteries and their care?

Thanks for the info. That's great on the batteries and motors not really heating up that much. My mSR is awesome in that respect. I have four batteries with two being larger 150 mAh ones and I flight them straight through with no cool down period(s) and zero problems. The gyro remains predictable with just some minor trimming throughout a flight as the battery wears down. I'd love to get an mCX, even though I find co-axes somewhat boring, just because I really appreciate the neat design and I can fly it in some pretty tiny spaces.

And, those 4 batteries flown "back to back" were on the mSR and NOT my CX2. Zero heat issues and I've read where many people do the same thing with no problems. I don't even own an mCX2... |

sviking, Pardon'. By the last sentence of your post I assumed you flew out 4 batts back to back in your CX2. My mistook

As I said before, those CX2 motors do get HOT, even with the heat sink and thermal paste applied. The batteries get warm, but that's about it. I do let that one cool down. However, I haven't flown it a single time since getting the mSR. In fact, I wish I'd have just skipped the expense of the CX2 and the batteries/extra parts for it and went straight to the mSR since I already knew how to fly full scale and R/C helos. I just didn't know much about indoor electric helos and figured the co-ax was the best place to start. I had NO idea how stable the single mail rotor micro helos could be and I was blown away by the mSR. In fact, I hardly even "land" it anymore. I just pluck it out of the air by hand and launch it the same way from my fat ass lazy chair. The CX2 is still a cool design, though, even if it flies "weird". The mSR flies MUCH more like what I'm used to. |

May I ask, which you think is more difficult? Real or RC? I know, what a question. But, I have had two copter pilots tell me if you can fly a rc copter, you can learn the real thing. Any thoughts? Lee

My situation was different but, looking back, I'd have to say full scale was harder because of the "Navy flight school" thing. Very academic and having an instructor breathing down your neck all the time. And, my job depended on it because, if I failed out, I'd have most likely been forced to go SWO and ended up driving ships. *barf* |
