Anyone have info on how to fix the servo if the top "collar"/"nut" seemed to have slipped allowing the servo shaft to have a small amount of play (probably 1/16"). Note, the servo was working, but I recognized a slight "unresponsivness" which caused me to check it out. That's when I noticed the play in the servo. Can I just screw that "nut" down...maybe I'll just pull that setup off of the servo board and replace with a new one...

Tighten the nut then add a very small drop of glue on top of the nut, should work

also apply glue with a tooth pick or xacto knife. Probably a "duh" statement but I've gotten glue in the servo gears and its nothing but bad news. It seems to find itself there even if you think your being carefull. You'd be suprised the little drops that get loose (probably notice them on your work bench )
Mine seem to have a larger gap as well. But I'll leave them for now

Ya, but does your "larger gap" actually allow you to move the servo arm up and down with a light amount of pressure?

I'm going to say 1mm on the right and rear servo none on left.

I was jjust looking at the box and it says 45.5g is this without battery?! I'm at 44.6 grams with all the mods... pretty sweet.

I wish I did, thinking of buying it but with the new gee bee beast and hyper taxi I'm going to be tapped out through the hollidays and first of the year. Maybe I can trade one of my v1 beasts for someones phoenix :-)

STU - I think my servos are sittin low because when I pulled the battery the throttle was all the way down. DUH such an idiot sometimes :-) Oh well I learn something new about the heli everyday. I'm trying to center the swash but I'm nervous I'm screwing something up.

Yes. Make sure both the sub-trim and main trim are centered for all channels before making any mechanical adjustments. That's pretty much a universal truth when setting up any heli.

You were supposed to flip one blade and rotate them both off to the same side. That way, the TIPS are right next to each other and it's much easier to see when they are exactly parallel to each other for zero pitch. At max (or min) pitch, the blades will form a "V" to the SIDE of the heli and not across it, which appears to be what you have done if both blades are angled downwards. With the method I suggested, one will go up and the other will go down. They will meet in the middle at zero degrees pitch.

And, if your mCP X has a flybar...you're doing it wrong...

Not all of them. I have two 3-in-1 boards and neither one ever exhibited any weird trim drift. I'd blame the servos or a sloppy head over the AS3X system.

Newer v3 Tail

How is the tail holding with v3 tail on the Mcpx? I want to learn/practice some flips,roll and inverts and is debating if I should get the stock or BL MCpX. If the stock motor is capable then I don't wish to go BL. Actually I am debating on getting stock mcpx vs Genius also. Durablity and 3D flying are my goal here.

But, where was the collective stick when you last pulled the battery? If it was all the way down the servos will be below center if you have any negative pitch at the bottom of your TH curve. Centered stick should equal centered servos which should equal zero pitch at the blades. Looks like you have some negative pitch in your TH curve if the collective was all the way down.

Edit: Just saw your other post where you figured out your throttle/collective was all the way down.

Unless you find one used, you can't "get" a brushless mCP X. Well, unless someone is now selling turnkey conversions, but I haven't seen those if they're out there. You'll have to do it yourself or find someone to do it. As for the stock motor, a lot of people are happy with it, but I hated my mCP X with it and didn't fly it for a long time because it wasn't any fun. And the beautiful summer/early fall weather had me flying the bigger stuff anyway. I've only recently rediscovered it after having a LOT more fun with the brushless conversion. Just yesterday, I logged 7.5 minutes with a new 550mAh battery and the extra weight didn't appear to affect anything at all, which is nice due to the extra power from the brushless motor.

Ok I'm leaning towards bad servos take a look at the chatter at mid stick. They can't find center AND I just cleaned them.. one of the servos, the fingers were bent a tad (one of them was a hair lower than the others)
McpX Servo Chatter at MID STICK... :-/ (0 min 17 sec)

I know you probably don't want to hear this, but often the "easiest" way to troubleshoot is to throw parts ($$$) at it. If I were you, I'd pick up some new servos and see if that fixes the problem. If so...you're done... If not, you have some good spares that you'll need in the future anyway...

Just a thought... Have you checked the fit between the swashplate the the main shaft at that point? Try disconnecting the swashplate at the servo links and moving it up and down by hand with the rest of the head as normal. Check for any roughness or binding.
