Next one on the way.
Flybarless collective pitch. Going to move into idle up mode which will be interesting, once I've learned to fly it.
Brings a completely new dimension into flying. Positive cp takes it up and negative takes it down while the blades stay at roughly the same speed.
100% throttle on start and end of the stick travel and about 80% in the middle. So go down from 50% and you get negative pitch and positive above 50%. Then it will behave in the wind.
I'm flying the MSRx now pretty solidly so I decided to move on to the less steady world of CP and have something to fly outside that will bit the wind back outside.

Hi Ian Isn't it about time you paid someone like Mick for some lessons, and flew the real thing ? ;D Just think of what a timesaver it would be for you. You could even take a few little trips up to Caithness, and get a really first class wax and polish job in return for a couple of joy flights. Kind Regards Alex P.S. Mike did a bloody fine job on his new pre-loved car, didn't he?

Yes, his car looks fantastic, puts mine to shame, I have two cars and they're both the same colour - silver with brown streaks!!!
I have flown helicopters, Alex and I certainly wouldn't sit in one of these models, The don't fly the same way at all!!
It would be nice if I could get up there on a battery!!

That's a funny thought... imagine travelling up to Scotland in a Honey bee "upside down", good god man, you'd be as sick as a parrot... just before you land you could point the nose skywards and rock back and forth.... If I DID have to fly in one of these (a mini passenger) I think I'd choose to fly MCX2 airways! No WAY would I get onboard a Solo V2 or a MSRX! Helicopter club this Sunday, really looking forward to it, I've managed to persuade a nice local girl to come along, I'll give her a shot of the MCX2 and "buddy" her on the sticks

Good for you, Mike. Someone to share it with is even better. I'm lucky in that the wife does actually take an interest and doesn't think I'm totally balmy!! Well, I got the MCPx off the ground and got it to hover! It's verfy similar to the MSRx actually. At first, I spooled up and the damned thing wouldn't lift at all. I checked the pitch of the blades and the settings were fine, so I thought I'd got a dud one. Anyway, I checked to see if there was any lift atall and when I held the heli, it was pushing my hand into the floor - then I twigged. You have to reverse the Pitch on the reverse switches. Reversed the Pitch and then revved and it went up like a rocket and dead stable in the air. The really unnerving thing about it is that it goes into negative pitch when you lower the throttle, so it doesn't float down like a fixed blade - it PUSHES down and when it lands, there is no way that it moves on the floor. The blades stick it to the ground so it doesn't topple at all. The only thing is that if you put the throttle down quickly, it will dive down at the floor and stick like mud to the ground!!! I then went into 'stunt' mode using 'idle up' and boy, do the blades spin fast. Also, the heli is bloody responsive and extremely fast. It's literally like a rocket. It goes up and down so quick and stops dead in the air. It's quite strange after a fixed pitch which 'hovers' in the air, whereas this actually flies up and down rather than float up and down. Very positive up and extremely positive down. In fact, I may play around with the pitch curve to soften the coming down because it is so solid on the floor that the force could flatten the skids!!! It really PUSHES down. The wind won't move this bugger for sure. If it gets any transitional lift, touch the negative pitch and it will positively cut through the wind. Good heli, but takes a lot of managing. MSRx is slightly easier but I can actually fly the MCPx and it's not as daunting as I thought it might be.

It's perfectly flyable!!! I can hover, turn, forwards but you have to do an opposite motion for every command given, so all of your commands are in effect, doubled.
It hovers much the same as the MSRx which I really do like. It turns left better but boy, am I feeling the collective pitch. It positive steams up in the air if you're not careful, but equally, it can steam down as well because the negative pitch can literally 'throw it' down and it sticks to the floor.
You need the negative to fight updrafts and transitional lift. I think this will fly outdoors amazingly well but until I have full grip, I'll potter in here.
One thing you have to be very careful of coming from a fixed pitch. Lowering the throttle if you get into trouble is not advised. If you suddenly lower the stick, the heli will go down so fast with that negative pitch, it would be smashed. The only way out of trouble is to cut the throttle, so it is IMPERATIVE to have a transmitter with a cut on it or you will have no heli left.

This is even better than the MSRx. Yes, difficult to fly but I now have it hovering and I'm walking round the room with it and it turns beautifully.
I can virtually fly it now (thanks to MSRx) since it is really similar in characteristics, although it has far superior control.
I took some negative pitch off because it's a bit ferocious coming down and I have tried stunt mode for a brief moment.
One word for it - stunning. Smooth fly once you have it sussed and I think a perfect intro into CP world. This flies like a real one virtually, except it does everything more aggressively and the G forces would rip your face off if you were in it.
I really have a grip of MSRx now and it has paid off big time with this beauty.
This heli is really worth flying if you get into the hobby in a serious way. You learn a lot from it and once you have a grip, it's a real fun fly.
In fact, it's a hard choice between MSRx and MCPx. I really like both a lot. Gone off the MSR of old big time if I'm honest because I now realise just how limited it is, although I guess it's a good intro to single rotor flying.
This is stunning though and I'm having a ball with it.
Pitch curves and throttle curves work closely together and boy do you learn it from this heli. I've found a really good setting that keeps it in real check indoors, basically by reducing the negative pitch, but I may have to up that once I get it outside in order to combat the dreaded transitional lift.
This is going to be a ripper outside.
When I've settled with it, I'll video all of the helis that I think are really good confidence builders so people can see how they all fly and compare ....
Just hovers ect, but it would give an idea;
MSR- 120 sr - MSRx - MCPx - there's real progression in them, but since I have a lot of time, I'm able to learn them pretty quickly. (plus the fact that I have flown helis for quite a while really before I got serious with them)
Book the MCPx for next Christmas - it's a classic heli.

Oh ... the joys of a programmable transmitter.
I've been playing around with pitch values and throttle curves and there's a huge amount of help to be had, holding these things securely in the air by getting the balance between the two right.
I've changed the blades to some KBDD blades, which are white and so easily seen outside. That itself makes a big difference - being able to see the rotor circle.
The other thing I've found is that if the revs are a little on the low side and the pitch a bit aggressive, as the battery drops, it starts to wobble under the strain. ie: the blades are spinning too slow for the aggressive pitch. (lift)
I tried lowering the pitch but then I couldn't send it up quick enough. (for me) So I stuck the pitch back and lowered the negative pitch so that it doesn't dive at the floor and upped the throttle curve quite a bit.
What a difference. I can now fly it - although I have to be very careful indoors because of the blades speed. They are capable of serious damage!!
I ended up with:
Throttle 0, 50, 80, 90, 100. That gives a solid kick in the bottom and a good hover area between 50 - 80. Goes up nippy too. Pitch - 50, 60, 70, 85, 100 This gives a good lift at the top but gentle in the middle so you can hover without doing yo yo's.
This also translates well to the Blade 450. They seem to be pretty good for me.
I am absolutely loving the DX6i. When you work with a CP, it's a godsend.
The MCPx is now becoming a flyable bird. It is a seriously good learning heli and imo prepares you brilliantly for bigger and better.

I've taken a step back from the DX6i to the DX5e. The reason was, slowly, as I get used to the MCPx which is a difficult thing to fly, I have been adding more and more negative pitch so it comes down as fast as it goes up.
I got to the point where it was set as standard -11 degrees and + 11 degrees pitch, so in effect, I didn't need the programming any longer.
The result is that it's much more ferocious in the air. It goes up like a rocket, but also down, so that 3d is a distinct possibility. (Upside down flying with negative pitch)
Indoors, it's a bit scary in that if it hits you, it's going to cut so I have been very wary of it.
Today, I took it outside for a proper fly for the first time in a small breeze, just to see how it feels when it's being pushed around.
I'm using extreme blades because they're heavier and give a bit more stability and I must say, the negative pitch is just as important as the positive. When a gust catches the heli, it does exactly what a fixed pitch does. It goes up like it's in a lift, but the negative pitch just pulls it down with no problem. So in effect, you're no longer flying on a flat plane and cutting the motor to let it float down in the wind; you're actually flying down in the wind. That way, it's much more stable. You just have to be careful with the amount of negative pitch that you apply.
With no walls and free space, this heli is brilliant. Damned fast - way faster than anything that I have and there is NO cop out. You can't just cut the throttle and ditch if you're in trouble. If you do, you will hit the floor so hard that it will disintegrate!! The only thing you can do is cut the motor out so it flops with no engine running and to be honest, if you're in trouble, the accident will happen too fast for you to find the engine cut switch.
So it's a make or break flight!!
I got it into the air dead easy since I've been hovering and piddling around indoors for ages. I felt that the extreme blades are more secure and the heli is less twitchy so I've settle for them. You can see them better outside as well. Mine are white but I may get some red or orange ones so I can see the rotor disc more clearly.
Up she went and lovely hover. A gust of wind took it further up so I used negative itch to get her back down to a sensible height. Switched in 100% rotor (Stunt mode) and boy do those rotors spin. Result ..... loads of extra stability in the wind. It's rock solid.
So I hovered around and did some back and forth over the grass. Nothing too high or too far away since if you lose contact (ear wise) with this bird, you could crash extremely easily.
This is a superb heli to fly outside. The CP is the key. At first, you feel that CP is a pain and makes the heli mad, but once you begin the learning process, your flying comes to life outside.
I've also found that the size of the heli and the space are closely related. I'm regularly flying the Taxi 100 yards left and right and 50 to 100 feet up on occasions when I feel brave. Then again, you can see it. The 120sr is faster so I tend to keep that nearer at about 50 yards left and right, doing fast circles and figure eights. I can send it a long way up and still see it, but it's less stable and I kind of get wobbly up there. The MCPx is close quarters for me. It's too small and fast so you could easily lose sight of it at long distance. (That's why I want orange blades) Perhaps when I feel more confident, I'll send it up but small steps or else I'll end up with a heli in pieces.
The MCPx is a definite learning machine. It's really pushing my flying and because it's small, I'd say that it was more difficult than a 450. The biggest problem with the 450 is just its size, not flying it. In fact, it's more stable.
Getting there slowly and it's really easy to be impatient but the more I fly all these helis, the more I realise that they are all designed for different flying conditions. Nowadays, I don't even think of taking the CX3's outside - they just don't fight the wind well enough. If it's totally flat - then fine.
So ....
Outdoors
MCPx, 120sr, MSRx, Taxi. The conditions dictate which one to use.
Indoors
MSRx, MSR, CX3, MCX and MCX2.
I rarely go out of their comfort zones nowadays - it's just not worth it.
I'd like an intermediate size CP for outside now. Something a bit bigger than the 120sr but not a 450 (yet) The sr comes to mind, but I hear that it has all kinds of flight problems.
There is a bigger Nine Eagles but I'm not confident of them following the sx which was a piece of crap.
