Better than a 3G for my 830mm ap heli????
Hello to all.

Actually i fly my 800 e ap heli for solo shoots, im using rotortechs 830 with the align 3g FB unit. The problem i have is that i cant take much time to take the shoot with the camera because the 3g doesnt has Self leveling feature, its only help with rate stabilization.

Because i cant aford an ace one and forget all the issues, im looking forward to the H3 helicommand and the skookum 720, both has inertial help, but in the sk720 they say isnt for ap use (i dont know why)

My final goal is when i let out my finger in the cyclic, the heli get self leveled with inertial (gravity) help. so i can take all the time i need to look trough my googles.

I know the drift phenomenon because isnt gps correction, but this is not a problem for me

Thanbks in advance for the inputs.

Nice flights and Xmas too!!!!

Just because the heli is level does not mean the heli will stay in position...

The Helicommand 3A/3D/Rigid systems WILL keep the heli level, as does the AP 2000I from Spartan RC, but neither one will hold position or altitude above a certain height from the ground. The heli will still be blown around by wind (if any). If a dead calm day then they do work pretty well at staying in one spot once trimmed out.

For position hold you will need GPS....

Chris, he clearly said he understands the drift problems without GPS.

helicam1980, check out the new helicommand HC-3sx. It will hold a level hover exactly like you are looking for and according to reviews it works better than the older helicommands.

What Chris ^^^^ said.

FBL units do not detect drift, they are 3 gyros combined to sence and control rate of rotation.

Most hover very poorly.

You need a full blown autopilot with GPS in order to park your helicopter work hands free, and then recover. (I recommend having an observer when flying autonomous)

The basic package from DJI Innovations will do that, if you are flying line-of-sight. All that for a mere cost or around $3000.

Don't know there is anything cheaper and simpler (and reliable) than that.

Gee you guys aren't even reading past his first paragraph.

Helicam1980, you are on the right track. You don't need the Ace One or GPS for a simple hovering aid. I use the helicommand in "horizontal" mode and it does exactly what you are looking for, levels the heli to aid in a hover while you do other things (like aim your camera or look away quickly at your subject).

You will have drift with wind and you have no altitude hold but of course you already know that, I know you know because I actually read your entire first post.
Most hover very poorly.
Haha, far from the truth! I think either you haven't actually flown one or you haven't flown one properly setup. My helicommad works excellent for what it is intended to do, keeps the heli level.

Thanks all of you for the inputs.

I wonder to know if the helicommand hc 3sx can maintain level flight for long periods of time without drifting (in the cyclic axis)

i can accept lateral drift because of the wind or tailrotor thrust

Helicommand will hold heli level but it will drift. It will drift while maintaining level. It will also move up and down without Altitude Hold aid.

So just look at it as there is no position hold.

If its not windy you can maintain position fairly well with stick corrections.

Hope that helps.

HI DJ!!!!

The 3sx manual says : "Additionally this unit features the well-known and patented Horizontal mode (self-leveling), which brings the heli back to horizontal attitude anytime you let go off the sticks."

so, did the 3sx has inertial sensors?? because if not i wonder to know how can remember and hold the horyzon all the flight

helicam1980, I think you are getting the terms mixed up.

The helicommand will hold the helicopter level almost indefinitely. But in this level hover, the heli will naturally drift with wind.

So when people say the helicommand drifts, it doesn't mean it drifts into a turn from level. It will stay level, but will drift with the wind. Does that help?

The HC has a autotrim function that you can set each flight. That tells the HC what "level" is.Robert

The HC seems not to be very stable. Also how far up will it work. Curious because this is fairly low cost.

It doesn't care how high up your are, only how low you are. They don't recommend using it less then 3ft if using the version with sensor in addition to gyros (green mode if I remember)...

I use one and it works great, I don't look away from helicopter and back up, but probably could if it's not too windy. Would love a position hold system, but cost has been out of the question...

The Skookum 720 is supposed to be getting a gps add on this year that will hold position and altitude. Also it sounds like the newest firmware version is supposed to be much better that the older versions.

I am planning on getting one in the near future.
