Not enough negative pitch

[vertico]

My lines are aligned on the grips / head however when inverted I have to give it full collective in order to maintain a hover.

What's the best way to correct this? Adjusting servo links? Through Tx?

Adjust servo linkage: zero degrees pitch at 50% stick. Guess I was lucky; I didn't even check mine but it seems dead on...

[vertico]

according to the marking on the head, I have zero degrees pitch at midstick

Did you check your pitch curve in the TX? What's it look like...

[lovespicyfood]

Yes, sounds like your pitch curve is off...

Mine was the same way, I changed the endpoint for negative pitch at 125% and then positive at 90% it felt alot better. ALot more even.

I had the same problem. I adjusted the pitch travel to 132% on the low side, hovers inverted really well now and punches out inverted just as well as upright.

Be careful increasing the pitch travel,you need to check full cyclic throw at full + - pitch.You can ruin the servo if you have too much travel with pitch cyclic combined..If I set my pitch travel over 100% and aile/elev at 100% the servo will bottom out and bind...

Didn't think about that, thanks for bringing that to my attention. So, at mid-stick I have 0 pitch, full positive works fine, I've got enough blade pitch there. How am I supposed to get more negative pitch if I can't increase my negative travel over 100%?

EDIT: Just got home and checked, no aileron or elevator binding at full positive or negative using a pitch travel of +100 -132.

If it is a problem then you have to give up some cyclic travel to increase pitch.For me I wanted more cyclic so I decreased the pitch trvel and increased elev and aile travels for quicker roll / flips...

I have been running slightly higher ail/elev travels at 110. I guess i need to find the sweet spot with these values and negative collective end point.
