its time to buy a stabilisation system...

what differences are in behaviour between HC in HORIZONTAL MODE and AP2000i ? where drift will be bigger problem? it is true that Helicommand works like a COAX heli and stabilisation is not so good like in IR based system ?
if i want to fly with Ap2000i in distance closerto building than f.eg 50m it will be a problem or not ??
i read all info in many threads and i still don`t know which one to buy
whitch one will be better option for AP if anyone tryed both ??

sorry for my english

50 meters away from a building you are not going to see much of an effect. 5 meters you might see an effect but it is still doable. Of course it makes a different on the size of the building and its potential heat signature. I haven't used the Heli Command but I would suspect it stabilizes as well as the APi. They each are going to have their plusses and minuses. You have to weigh all the features that are offered and make a decision. I don't think either one is wrong.

Here's a review I received from another member.

Here are my impressions of the HC3A as you requested:

I was going to post an in-depth review of the HeliCommand 3A, but a search shows others have achieved the same results as me. So the info is out there.

Basically, it works as advertised for me.

Setup was easy without the PC interface. I followed the steps in the instruction manual and was done in less than 20 minutes. Later I used the PC interface to fine tune the gyro settings. Easy.

Position hold works, optimal height seems to be just below eye level. I will probably only use this occasionally for novelty effect. Once it oscillated quite a bit, had to turn it off in a hurry.

Horizontal stabilization works well, in my opinion just as well if not better than the IR devices I have used (CPD4, FS8, General Laser Stabilizer 3D). The key difference is it does not matter if you take off beside a tree, in the dark etc., the heli will stay flat.
This very significant to me. I flew in clouds, rain, strong wind, bright sun at different times of day and all from right beside a stand of trees facing a field. No IR-type leaning issues.

Autotrim took a while to figure out, but that ends up being easy too. Hold the heli in flat hover for about 10 seconds, hit the trainer switch (just a blip is all that is needed) and you are done - calibrated. Do not use tx trims. If you do not want to use autotrim, use the tx trims to achieve a flat hover, land, press the "set" button, cycle power on the rx and you achieve the same thing. Once trimmed either way, the hover will remain flat no matter what the wind conditions are. Yes it will drift with the wind. I did not enable autotrim until after I had decided not to use the internal tail gyro.

I believe the HC3A has a sort of "stick priority" built in, as you use the cyclic commands, stabilization is reduced - it is strongest with the stick at center. This may be why some say the AP2000i has "better" (stronger) stabilization. I used mixers to reduce the stabilization effect on cyclic input on all my prior devices so I am used to the effect.

The tail gyro in the HC3A is good. It worked really well holding the tail of the Bergen. It was too sensitive at first and I had to adjust yaw rate and expo in the PC interface before I achieved good results. Hold and response was as good as my 401, but I experienced noticeable tail jitter at times, probably due to gasser vibration, so I have since gone back to the 401. I would think in any electric or smoother heli the tail gyro would be more than adequate.

Better than an AP2000i? I have no idea as I have never used one, but definitely better than the other devices I listed above. I was going to get an AP2000i for comparative purposes, but I am not so inclined now as the HC3A exceeded my expectations.

... But honey it was only $$$

Get the helicommand, you'll be happy with it. I have the spartan ap2000i.

Hows the helicommand at height? Doesn't it have a "low" recommended max height limit?

Which is worse, ignorance or apathy? I don't know and I don't care!

I just tried one out while I was in Toronto.

I had two people PM me their opinions and I cut/pasted them here.

After testing it out in a river bed with tall cliffs on both sides, I was very impressed.

So much that I just ordered one.

I won't give up my ap2000i just yet though. I have yet to test the HC out on my heli's but when I do, I'll let you guys know.

It does work great and feels like a very very large coax. It does drift like my ap2000 but I need to spend more time with it and set it up on my birds.

I would recommend one just by the 20 mins of flying.

The position hold is only good for 4-8feet off the ground and is more of a novelty thing.

The position mode on Heli Command won't work past 3 meters in altitude. As another poster said it is really a novelty item than a useful feature. If you want to use Heli Command in AP work you really need to spend a lot of money to get the commercial version.

It works fine as a 3 axis gyro. However the tail axis doesn't work quite as well as a dedicated heading hold gyro like the Futaba GY401. JR, CSM all have similar HH gyros that work better than the Heli Command. I bought the Rigid version and it costs me over $600. I can hold my heli a lot better in the wind than the Heli Command can.

I can see that is a good aid to help flyers when visibility is limited and the weather is poor.

OTOH the Spartan is a lot less expensive and if it does similar 2 to 3 axis dampening it should be a better deal.

My opinion is definitely bias but I did use a few so called "autopilot" starting with the BTA to the FMA to the Heli Command. I have to say both the BTA and FMA worked excellent in a fixed wing trainer. It is just not quick enough to keep a helicopter in a stable enough position for my work.
