I'm thinking I'm going to try some flips and stationary rolls soon. I just read the thread about flips but I was wondering if there are any tips for the stationary rolls?

Also, my throttle curve(os32 in a raptor) is 100, 50, 30, 50, 100 and pitch is linear 10 to -10. Will I need more throttle anywhere to prevent it from bogging down? From what I read these manuvers require a good amount of power.

Timeing is the secret. Easy on the collective stick and always try to be as 0 pitch when the heli is on its side with the disk 90 deg to the ground.

I have my machine set up with -9 0 +9 and about 85 50 85 throttle curve. I have cyclic to throttle mixing set up. This way I still have reserve throttle for the cyclic mixing to help out at full collective.

I am no expert by any means, but I think your throttle curve is a bit to deeply V'd if that makes sense... 30 percent at the mid stick will give you a jerky sensation when you go positive and negative on the pitch. Especially in Flips and Stationairy rolls where you hammer on the pitch and off fairly aggressively, going from 30 points to around 70 or so will cause harsh movements on the tail as well... I would say bottom out there around 50.

Better to be safe with a high rpm than have it die on ya... IMHO

The way I do stationary flips and rolls is to first give a small amount of up-collective. Then restore the collective and apply the cyclic, before the model has had a chance to appreciably move upward.

I don't try for zero collective at the knife-edge position at all. I hold the collective positive until the model is almost all the way inverted, then smoothly, but quickly, apply negative collective. The negative is held until the model is almost upright.

You will have to practise, varying the collective timing until the manoeuvre looks right.

Don't try for full cyclic either. That tends to load things up too much in 30s. Sometimes a brief pause in the inverted position to recover head speed can help.

I have no idea why zero collective at the knife position doesn't produce a nice, in-place roll or flip, but it just doesn't, for me at least.

Your throttle settings per your pitch setup will make you CRASH trying to attempt flips and rolls! The linear curve for throttle per your pitch setup should be in the range of 100,75, 50, 75,100.
Moreover, I would suggest you practice upside down maneauver first starting with a big loop. Once you get the hang of flying upside down, flips and stationary rolls will be piece of cake!!!!!!

Keep on flying and have FUN!
