Default Self Leveling with collective

So I got my brain to self level and add some collective when I hit my trainer switch. I feel this is safe because the brain only self levels to a right side up position so no need to worrry about it when being inverted, it will just go right side up and climb.

And frankly it works pretty good!

AT :25 i did a quick push forward on the elevator and then hit my bail out switch as you can see soon after it levels and climbs. Yes there is a drift, but thats from the momentum of the movement im bailing out from. Starting at :40 i go into an inverted hover and then hit bailout. it quickly turns over then ascends to a vertical climb.. i released the bail out switch and it soon descends due to the fact my collective was below mid stick. after release of the switch you go back and adjust your collective to positive pitch. i repeat this at :58

How it's done. My tx is a DX8 and here is a video tutorial.

Cool idea. So did you do it via mixing trainer to collective? How safe does it feel considering increased pitch during recovery? A brief instruction would help. Thanks.

I would like to hear more as well! Is this something electronic in nature or a new maneuver you taught yourself, like getting all the hovering points down?

Ill explain in detail later. I woke up in the middle of the night with a brilliant idea. I just tested this morning in the right side up position and it worked pretty well. I'll be going in about 2 hours to the field to test the inverted. Ill be sure to take some video.

My setup is a dx8 transmitter and I am using all 3 banks. only 1 bank has the collective pitch and it is activated via the trainer switch.

We are testing that too and we are having good results too

If tests go on well we would like to implement it as an option, something like a check box to check if you want to add collective after recovery and a slider to set how much collective to add.

The good thing about it if we implement it in firmware is that we apply collective only when we are sure the heli is right side up

guessing he toggles fmod/pitch curve with aux signal changing banks.

Highfreq,

What product do you sell?

I'm having a terrible time with my align 450 pro v2 3gx, even after spending an hour at align HQ in Cali we still can't get the shaft or one way to rotate freely so I'm looking at other stuff, but still fbl, so I'd like to take a look at your product.

Regards,

Steve

I found a way by myself:

- switch selection: gov-switch to K7, trainer to K8

- mixer K8>K7

-> switching between all 3 banks with gov-Switch (K7), if i press trainer, it mixes up to K7 100%
(Bank 3 with Selflevel).

Can you add a delay on the collective part of the mixing..? If I remember the Helicommand start to add collective only when the heli is close to level.

A 450 is very fast and quick, but with a 700 size heli it's not the best scenario, if you add collective with bail out at the same time when inverted, first this will bog the motor badly and the heli will make a big arc while it recover.

I would test and start adding collective only in very small increment with big size heli.

On the dx8 there is a servo speed function, but doing this will also just slow down the switching into the bailout bank.. You have to understand that these 2 actions happen simultaneously and very fast that the downfall is very non-existant at a inverted position. In your mind go over the action if you will..

You hit bail out and the heli starts its right side up movement while pitch increases. It may go down but for a fraction of a second but the outcome will be it climbs out.

Rather then slow down the movement, what you can do is under advance menu under the bank which contains the bail out, increase your cyclic rotational speed.

you can do this with a dx7, you just wont have a momentary switch, you will have to remember to toggle back to a normal bank once it self levels and climbs to a comfortable position for you.. It will just get some getting use to as your muscle memory build up.
