My loops are not loops anymore. My loops are not even flips anymore. They become some entangled "#!@ get me out of there" mess on the sky. WHY?! What am I doing wrong? What to do to get into the loop not being leant on one side?

Is forward speed (fast forward speed) crucial for good loop? I seem not to be able to make my help going faster anymore (problem is in me I am sure).

Is it possible correcting being bent on one side just as going into the loop - while being in the loop?

Did you have this 'period' when suddenly things stopped working for you? :(

I don't know if you're just starting doing loops or not, if yes, try to have a buddy look at your stick movements when you loop, maybe you've input some aileron while pulling your elevator. I said it cus it happened to me once when i first started to loop. Hope that helps.

Might want to go back to a "beginer loop". Start with trimming the heli so it will fly fast forward with little or no aileron. Now fly by at full speed, collective all the way up. Now pull aft cyclic graduallly, timing it for full aft cyclic at 12 o'clock. At around 3 o'clock begin to ease forward on the cyclic until your straight and level. This will give you a more egg shaped loop. I have found forward speed is helped by a little nose heavy balance, higher head speed, and longer blades. If you are not going fast the loops will be hard to get looking round.

May I ask stupid question? How? What "with little or no aileron" means? O: )

Now fly by at full speed, collective all the way up.

Maybe I need to practice that first. Also, after crash I have set heli slightly differently (have not idea what I have done aside to, maybe increase rotors max. pitch) - now motor is having trouble at full cyclic...

Now pull aft cyclic graduallly, timing it for full aft cyclic at 12 o'clock. At around 3 o'clock begin to ease forward on the cyclic until your straight and level. This will give you a more egg shaped loop. I have found forward speed is helped by a little nose heavy balance, higher head speed, and longer blades. If you are not going fast the loops will be hard to get looking round.

But, shouldn't I ease off collective near the 12 o'clock? I thought that might save me another set of rotors O: ) LOL

Anyway thanks :) . I have, for now, decided to practice stall turns only and see what I am doing incorrectly going into vertical.

I often ended up "sliding" to side while being vertical. Now add some tail movement (involuntary) and loop or flip will end up in position close to 90 deg on at least one axis of not more... My brain is not trained to handle those yet... LOL O: ).

So, FFF and proper stall turns for now + to see why I am bogging my rotors so easily (physical settings, software settings or defect in brain! LOL)...

No Ail is no left or right yaw (I think) Go striaght fast with no lateral input ...

Yes, you want the heli to be trimmed so that in forward flight you are not having to hold aileron cyclic. It makes it hard to loop with a heli that wants to roll. If the heli's motor is unable to sustain full collective you can back off to a point where it can sustain rpm. Or redo the setup to where you are able. Its not essential to be at full collective, the goal is to go as fast forward as possible. The faster you go into the loop the less you need to reduce collective at the top to make a round loop. I usually stay at full collective until about between 10 and 11 o'clock. Then reduce collective slightly over the top and hold until about 3 o'clock. And increase collective to pull out to level. I try and concentrate more on elevator cyclic to make the loop round rather than useing much collective (I would guess about +2 to +4 pitch around the top of the loop). If you go into a loop with the heli not going straight the HH gyro can turn the tail out. One way to help is to reduce the gain on the gyro. To find the cause of the rotor bog can be some work. I would start with checking the pitch.

I start the first quarter with collective only, then feed cyclic until I'm close to level inverted at 12 o clock. That should get you going.

Also doing the loop against the wind definitely helps.

I've practiced going straight into stall turn for two-three sessions now. Going up and correcting it while it is going into the stall turn. It is still not perfect but I am getting there.

So - when vertical and it is not sliding to any side it is far easier for me just to continue without messing with collective a lot until nose goes through it and starts pointing down again...

Now I need to sort out the problem with bogging the motor and practice FFF... I still cannot make my heli going as fast as I would like in forward flight. Not sure but somehow I thing that these two are somehow connected - I can hear head speed going down as I push collective which is bad...

Thank you for all you help :)

This is really good advice, I fly mode 1 and at the beginning was inadvertently inputting rudder due to being too tense. The worse my loops became the more tense I became and the worse my loops became. This set me back months.

Also make sure you enter into the loop nice and straight. To test this try doing stall turns on your left then your right, you should be able to fly back and forth along the exact same bit of sky if you are tending to fly wide of this line you are probably not going up straight to begin with.

Strangely enough I am flying mode 1 too! :rolleyes:

I have done more or less that same: started practicing stall turns and making myself correcting it while I was entering it - so as soon as I notice that it won't be straight I would start correcting it and continue correcting it until being vertical. That helped a lot! :D

Thanks everyone :)


BTW I've practiced it on simulator and deliberately went up with some roll and was making myself correcting it as going along.

We expect vids of expertly executed loops soon ... :)

LOL. I could have almost provided it today if I knew I was being filmed and if my Mini Titan worked properly. But I almost have a video almost crashing it (not my fault this time) and I did only one loop... But this deserves proper new thread...

As soon as I fix it I will make sure someone tapes me making loops :D

PS Today I realised that slightly more powerful motor plus time on sim did me good - I was making loops - even one after another - with an ease today... (Mini Titan permitting it...)

Power does help, well done.
