450 how to 90 servos on a sport v2 with angled servos placement

[johnrc]

I put my sport v2 away for 3 months and it did fly at that time but checked the bird and had 0pitch at mid stick and 9pos and 9 neg pitch, But now it won't come off the ground now. and is the flybar cage suppost too be really lose or stiff

That 90° on the servo arm should be in reference to the horizon, (or table top, if that's closer). Use the main gear as a reference point on that top picture and match the other arms to that level.

I will do that EyeStation thanks for you that info

I have flown the same heli for a year now. There are times I enjoy the flight more especially in some 5-8 mph wind than my 450 Pro. Seems the flybar handles wind better than the pro V2/3GX.

Regarding the flybar cage. Parts do wear and become loose within the cage. Especially the seesaw assembly. Particularly the screw that fixes the seesaw holder (Align Part: H45140T). I would keep an eye on this part since it will effect blade tracking. Otherwise, the cage fixed points should be tight and without play. Play in any fixed portion of the cage will cause vibration or throw blade tracking off making it impossible to get good blade tracking.

Regarding servo 90. The servo arm should be parallel (90 degrees) in relation to the main shaft.

The heli should come off the ground at about 5 degrees positive pitch.

When the blades are at about 5 degrees and you have enough head speed she should get light on the skids. If your cage is loose this may be effecting the blade pitch and could cause her to hit the dirt before lift off depending on the pitch of either blade.

Check the blade pitch at mid stick (with motor disengaged of course).

Ok i now have a 00.1 pos And a 00.1 Neg mid stick And 11.4 pos And 11.4 Neg is this ok to fly and it is the same for both sides

Just put new parts on the blade holder and the cage and i do have a flybar lock and everything involved

Your pitch degrees should be fine. My personal preference is 12 +/-. However, I have my radio (DX6i) pitch curve settings at 43% and 45% and 50% and 75% and 100% to prevent too much negative before lift off and landing while not in idle up mode.

Make sure to check your blade tracking. This will confirm a solid setup (without loose parts) and a smooth spool up.

Let us know how it goes.

Hey just want to say that i darn sure i have everything set on my 450 sport now 0 pitch at mid stick and everything else is level also i have 11.7 and neg 11.7 and 8.0 just got to check with a flight tomorrow if not to windy here?

Good luck on the flight. It'll probably feel like a whole new bird.
