I have never lost a link in six months. The first mod I did was to tether the links with thread and glue, and did the hot glue dab on guide forks. Last week I got the MH head so well see if that proves to be as useful to keeping the links. When I installed the head, I finally retired my original links as they had bent a little.

I was looking at the fixes that everyone else was using for the "lost linkages" problem and was about to start tethering a set together with fishing line when I came across this post doing a Google search for other fixes.

I really like this method...should render the lost linkage problem almost non-existent. I've already been through more crashes today since implementing this fix than I have in the last two days.
Not the best fix. These blade links are going up and down 4000 times a minute. This fix will add extra friction to the ball joints and possible rubbing on the mainshaft and also possible interference with the rotor hub anti-rotation forks at full pitch up and full cyclic. If you have to use rubberband, do it at the forks on the rotor head and don't let it touch the links. I use fishing line and it's been working great. Never lost a link since.

And I want to know if the Ebay price made it worth not going to HH and paying the 160 with free shipping.. So if they are going for 130 shipped than it's about a toss up I would say..

I've owned a mCPx before but I basically tried to go right to doing flips and stuff with it before I could effectively fly it. I was mildly successful but ultimately got frustrated and sold it.

SO... now I'm going to try and master normal, scale flight first and THEN jump into 3D once I'm ready. Today was a very successful day. Zero crashes and I learned a good bit about flying it. I figure if I keep it up I should be decent with normal controlled flight in a few weeks - maybe a month, maybe two. But I'll keep practicing as long as it takes.

If you tame this heli down enough it's pretty darn docile and it's rock steady. The gyro is awesome.
That's basically my story and my thought.. I can do figure eights at the park, and some circles.. it's difficult, and I don't trust myself to do it in the house yet.. but I'll get there.

Thanks for the tip - I have V2! Now at least it seems like the heli is talking to the servos... Unfortunately now it's not acting correctly... On spool up the tail was starting to go counter clockwise and I used the rudder to bring it back and it tried to flip over again! I didn't bang the rudder or anything...

Hope you follow the manual instruction changes and bind your DX8. It happens to me before. After I follow the new procedure and rebind the DX8, it works fine for me.

heli newbie here with a dumb question...

Just picked up an mcpx2 and bound it to an oh so advanced dx5e. Getting off the gound's okish and the heading holds pretty well, but I wanted to make sure the rest is responding like it should. It drifts left a little, give it a touch of right cyclic (rates on lo, normal not stunt mode) then recenter stick. It heads off to the right and keeps going sometimes at the same rate sometimes picking up speed as it continues on. Same responses right/left/fwd/back. I can keep it within a 10ft square for up to 20 seconds but that's been it after some practice. I'm pretty good at chasing flys with a coaxial, but maybe I just need lots of practice. Thanks!

correction correction correction, Yep the stiicks will be moving all the time. When you give a correction once the heli starts moving you actualy almost over correct opossite to slow up the heli or it will keep heading the same direction. If that makes sence. If you just bring the sticks to center you are just leveling the the swash with no correction to stop the foward motion. use small stick movements and after awhile it just comes as instinct and with no thought. Sounds like your findihg it doesn't fly like your coax Good luck

+1 on the last post - the mcpx's 3 axis gyros hold attitude not position.

It is pretty good at keeping in a hover though with only a little correction needed and some have managed a hands off hover for a few seconds and I have done so at times but as mentioned you need to fly the heli, once you get used to it look out flies!

hi i have a mcpx, with upgraded metal/carbon frame, and XL aluminium tail boom, it has shudder or vibration at slow speed, is this due to the extra weight if there is extra weight..
i have another one stock standard... and it doesnt appear to do this.

I wouldn't think the weight is causing the shudder, this is more likely from the main pinion not seated or a bent feathering shaft. When you say slow speed are you meaning slow forward flight or low head speed?

Have you upgraded the blade grips to aluminium ones? A friend just took some off his as they caused more vibration that the stock set.

low head speed, still using stock blade grips, and main gear is seated ok.
i will check out the feathering shaft, and possibly try the rubberband trick on the blade grips...

I wouldn't fly with a low head speed and use 80%+ throttle for all of my flight settings (actually I might just use 100% flat for flight modes 1 & 2. ) To check the feathering shaft take one blade off and spin the f/s screw if the other blade moves up/down as you spin the screw the shaft is bent.

Check the blade tension as well as if they are too loose then this may cause a shudder at low speeds.

Yep, that's so true..
1. Main Gear not seated properly
2. Feathering spindle slightly bent
3. Main shaft splitted
4. 1 of the Servos dying slowly

1&2 happens so frequently that Eflite should publish it in its Troubleshooting SOP.
I did not believe 3 until I had a shudder that wouldnt go away with 1&2 fixes already applied. And I experienced 4 only after several hard crashes that required rebinding to the tx to arm the servo that wouldn't move after the crash.
