Well that'll be another night as work in the morning and in the evening it's meal and theatre. My brand new tail servo is faulty so sending it back under warranty and ordered a savox servo to replace it with. Then set up the MEMS gyro as previously stated. Have final bit of thread lock to do on frame and then she'll be finally ready for testing.

I'm not getting it now I checked again and not the right one. I've been refunded and order cancelled. I really want to thank everyone who has commented. This is tough for me not only because it really the first ccpm heli I've built but I'm a stubborn person that wants to learn. I've taken on board what you guys have said and now looking to get correct servo. This is impacting the speed of the build which in its self is frustrating but I'd rather be safe than have an accident. Oh and Tony.... One of my club members suggested I dial down negative pitch so that if I panic I don't throw the stick down and suck it to the floor. You suggested 10degrees of positive (or between 7-10) would you just suggest I set equal pos and neg in pitch?

What I do is I set the helicopter up with a linear pitch curve and set the positive and negative pitch the exact same (within a half degree). Then, I set my pitch curve to 46 48 50 75 100. This will give you max positive, but only about 2º of negative pitch. But ONLY do this in normal mode. In IU1 and IU2 I always run a linear curve. Same with TH as well.
OK last question on the tail, I have installed servo connect gyro and centered everything. the tail blades and slider are in the middle. IE I've not put any positive pitch in tail blades at all they are dead straight with the boom. And what tightness should I give the tail blades so their tight like main blades or just enough that they will stay straight.

You should have some pitch on the tail blades at centre stick to resist torque. The linkages are usually designed so that the part of the lever arm that goes between pivot and pitch slider should be aligned perfectly parallel with the tail boom at mid stick. This gives roughly the correct pitch angle.
The blades should be just tight enough that they can stay horizontal without pivoting down. Main blades should be the same, with heli held on it's side they should stay horizontal but drop if you give the heli a slight 'jerk'.

Ok I see what you mean, so I'll keep the slider in the middle I've where it is in the picture but I need to adjust the control rod so there's some pitch in it to counter the rotational toque. Ok well that's an easy fix ta very much

Oh and Tony I can't get the mems gyro to work so mate gave me a Futaba gy401 which I've now fitted and seems to be working well. Still not got round to lock tightening frame bolts and link rod supports on the boom but that's it as far as the build. Off to mates tomorrow so he can go through it and check I've not missed anything out. And program the YEP 150a ESC. Beginning to see the light at the end of the tunnel. Cheers Tony and guys.

Is it me or does it looks like your tail rotor hub is twisted? Your tail blades aren't parallel with each other. As for swing, Lee has a video in general helicopter chat.Cheers fella, my mate was supposed to help but he's about as much use as a one legged man in arse kicking contest. So looks like I'm doing this on my own. Tomorrow night I'm going to go through frame bolts and thread lock them all re attach my tail fin (painted it) re check my pitch and then she's done. To say I'm bricking it is an understatement. Waiting for new fly bar as mate bent mine (don't ask)
