I finally did my first loop ever today perfectly with my Mini Titan. When I came to do the second one the heli did the loop almost but went into the ground nose in. My pitch was +10 and -3... Should I have like +10 and -10, and idle up mode for doing something this basic??? Could this have been my problem?? Any thoughts. thnx. Now I'm scared to try again!!

Yes, anything other than hovering should be done in idle up so that u have your +10 0 -10 pitch but also have your motor spinning at mid and low stick.

Otherwise u will drop out of the sky like many members here have............

If you have enough speed up FF going into the loop you can carry it all the way through without any negative pitch other wise YES you will need some negative and I would suggest doing it with Idle up becaue if you don't do it right well you already found out the hard way

Runway? what runway??

NO...you dont need "much" n0egative pitch for loops but you definitely need it to come down...eventually as mentioned.

Visualize what the heli will do based on its position and blade pitch angle.

When going up...you have speed and lift...eventually you want to reduce your pitch as you get to the hight end of loop...to the point where the pitch becomes zero...then some negative to maintain height and as the loop continues you will ADD positive pitch again.

Good job on the first loop and next time fly three mistakes high!

Best of luck!

-6 +5 and 10 are fine for idle up and doing rolls and loops. Have your throttle curve 100 75 50 60 or what ever keeps the rotor speed under power when u are inverted and -6

Any thoughts.
Set up your idle ups.

In you situation, sounds like you were in normal mode? If this is the case and your pitch was linear, I doubt if you put in much, if any negative pitch. And, if you did, you were losing head speed? So when you went to positive pitch again, your heli wasn't at full head speed? I would think that would make recovery difficult.

IMO, normal should be used for hovering only. If you go inverted without power, looks cool. But..... I'd leave it to the pros.

Set your idle ups, and do one loop at a time.

Practice, practice, practice.

recovering from the crash is the hard part.
