Setup Tips for your MCPX

I have received a number of PM's and emails about the MCPX and there appears to be one common theme..

Out of the box the MCPX has too much negative pitch and not enough positive.

I have just created a video on how to correct this.

Mine flies really well now and I'm very happy with these settings.. hopefully they might benefit others.

Step 1 - Remove thethree Cyclic links and wind them out by 720 degress (that is two full turns) anti clockwise.

This will lengthen the distance between the servo and the swashplate, reducing negative pitch and increasing positive pitch..

Step 2 - In your radio..

Normal Mode

Throttle curve - 0 40 60 80 100

Pitch Curve 30 45 70 85 100

Idle Up

Throttle curve - 100 100 100 100 100

Pitch Curve - 0 30 70 85 100

Pitch Servo Travel adjustement 70% and 74%

These settings give me a really nice flying heli that flips, rolls, and flys inverted really well without the risk of over pitching positive or negative and getting tail blow out.

Here is a vid of all of the above..

And another of how it flies with these settings..

And it flies nice inverted also

HI, does it matter at all what Radio i'm useing for these settings? I have a dx6i

The settings will work perfectly on the DX6i

Rob i thought i heard on one of you vids that you did a mix on your DX8 for the tail. what did you do and how did you do it. I have the dx8 and have never done a mix. If you could make a vid like you did up there that would be beyond spectacular

Thanks. love the vids keep them coming!

Hey Rob, should the pitch be same for pos and neg,like u said approx.9 degrees. mine has a lot more pos. and i havent changed it ,but i had sent it back to horizon for servo noise,maybe they changed it?

Speaking of the mcpx. went to the hobby store yesterday to snap one up as their catalog said they had one bnf left. proprietor said the supplier told him to take them all off the shelf and not sell any for 10 to 14 days as the head was being refitted and he was getting a shipment of replacement parts in. anyone else heard of this. or know whats going on. thanks for any info. Dave

have any of you received your replacement grips from horizon hobby yet? I just got mine the other day and I noticed that they sent instructions on how to send back the old pair of blade grips. They even sent a pre paid ups packing slip so I can just drop it off at ups to send back for free. Is it necessary to send the old blade grips back to Horizon hobby, because I just assume fly my helicopter as it is until I have a problem with the old blade grips. Either that or replace the old grips with the new ones they sent and keep the old ones for a temporary back up. Have any of you sent your old blade grips back?

Sounds like since this is a fairly serious safety issue, Horizon would want to get all of the old grips that may fail out of circulation, thus the free shipping label, so as to encourage people to return them.

I'm not speaking on Horizon's behalf, just my thinking on it.

I can see though, that you'd be reluctant to send a good set of blade grips back. they might make a good backup, like you mentioned. but do you really want to take a chance that a blade may fly off unexpectedly and injure yourself or someone else. [X(]

Just something to think about.

hi, yes ideally the pitch should be the same positive and negative. they may have adjusted it for you..

Hi, sorry, just saw this post now.. I will do a vid for you tomorrow.

its 4.30am here and I gotta go to bed.. I spent all night building another 450 Pro.

Hi, I tried the above settings on my DX6i, and the new mCPX I have acts really weird, I dont know if its the radio settings or the bird itself.

I thought the cyclic should return to center with the stick under power, and this one doesn't, at idle it does. Instead when power is applied, if you apply left forward, right, or back cyclic, it stays there when you return to center. I have to move the stick to the opposite side to bring it back. I dont think this is normal. I also dont have throttle unless I press the throttle cut button on the transmitter, so I think I have something screwed up, not sure what though. Is this all radio, or is it bird?

Real quickly, it's running late and almost time for bed.

I love to experiment, and wasn't overly thrilled with flying in the house. The heli seemed a little irratic when flying in NORMAL mode, with a DX6i and the settings in the manual for throttle and pitch curves. So, for the fun of it, I changed the pitch curves to 30, 40, 40, 40, 40. The heli flys much better and hovers even better yet. Similar to a fixed pitch heli.

Of course you can adjust the 40 to any setting you like. I tried 40 first, but I'll probably try others tomorrow.

im still not convinced my blade mcpx can fly upside down. I can fly my trex 600, 450, and 250 upside down in a hover and around but this mcpx will not do it. Every time I flip this helicopter over the tail just wont stay still. It always ends up on the ground and then I more than likely end up replacing one or both of the pushrods to the blades that always pop off.

Have you measured the pitch in neative and postive? Stock mine had WAYtoo much negative pitch until I adjusted all three pushrods out by 2 turns..

Too much negative pitch and you are probably bogging down the motor and the rotor drag would be too much for the tail rotor and it blows out..

What radio are you using?

That is an interesting pitch curve, I guess it is Fixed pitch..

My helis would not even lift off the ground with the pitch at 40%, that is Does your radio go from -100 to + 100 or from 0 to 100?

Mine at 40% would be about 4 degrees of negative pitch.. have you adjusted the linkages?

PS.. LOL.. I thought I was going crazy as I'm sure I had replied to this post.. but just realised it was a different thread.. Doh!

Hi, just got my mcpx and I would like to use my hitec "eclipse" w/ a spectrum modual on it to fly this with. I fly my other heli's with it but this is a much advanced machine. Has anybody used a hitec and set up with this machine? If so could you send me the set up? I have never had a machine that I could use "Heli" set up on my hitec. I have tried to set it up as a noncomputer setup but I don't think I have it right!

Thanks Rob
I have used the above pushrod and transmitter settings thats a great improvement i wonder why they all come out of the factory with so much negative pitch .

My first post on this forum …

ust got an mCPX RTF, my first foray into RC for about 35 yrs. This thing is a lot different from flying a big fuel-powered plane around in circles on the end of some bits of string…

welcome to flybarless gair heres a tip 1 the servos wont recenter like normal servos on this bird tip 2 spool it up slowly and slowly counteract the way it wants to tip etcetc as far as the first post these are settings on the users preferance ! its a good starter point but you may not like it if your first time user then u wont see any differance in this the point im trying to get by is wether your a "pro" or "beginner" the settings provided by eflight work fine ! take for instance the expo settings in the eflight suggested i DONT like the way the bird flies with the settings so i turned it back to 0 and fly without it sooooo i guess its all the way you feel comfortable with the bird and how it react and handles ! i have read all over about the bullet blades and non bulletts i prefer the non bullets bottom line ITS ALL ABOUT WHAT WORKS FOR YOY AND HOW COMFORTABLE U FEEL WHEN FLYING !
