Status: offline 		hi everyone, i just got a zoom heading hold gyro for my blade cpp. first off i have a futaba 7C tx and in the gyro page, it'll have 0~100 gain in either A or N, i have no idea what A or N is, so it's like this A100 ~ A1, 0 , N1 ~ N100. my guess is that A is for AVCS/heading hold and N is for normal... the manual has either a typo or gramatical mistakes, for i have no clue what it says in the manual.

second issue, i have to turn the gain way down (30%) to stop the tail wag, and when the gain is this low, the tail won't hold during a climb out, is this suppose to be happening? i tried both A mode and N mode and disable remote gain, but still the same. if the gain is high, ie. 80%, the tail will wag badly but will still hold really well during a climbout. please help here, i had it better with revo mixing and stock gyro than this hh gyro.

anyone using eflight G90, this gyro, or the telebee hh gyro, please help me

Status: offline 		Yep, I can give you a lot of info, I've got the G90 on mine.
First off the radio just thinks the gyro remote gain is like another servo, the travel to the left sets the gain in one mode and the travel to the right sets the gain in the other mode, sounds like you got that part figured out OK.
Second the problem you are having is most likely not the gyro's fault but the tail rotor's fault. There is so much inertia with the stock tail gear and big blade that the thing just won't accelerate fast enough to keep up with the gyro input, so if you have enough gain to do any good, the tail will twitch, I call it "ratcheting" because with that gear that's what it sounds like.
And on descents, when you throttle back, the best the motor can do is just stop totally, and that big blade keeps turning for a bit so the tail really will drift.
The best solution that I've seen is to go for the GWS direct-drive tail system. It is unbelievable how much better the tail will hold, and it sounds a lot better too. Plus the tail motor is more reliable and of better quality for about the same price.
Another very important thing to consider is the voltage drop. The stock 800 mAh battery just can't keep up with the heavy demands of acro flight. If you can get a 1320 mAh 13 or 15 C LiPo, it will also help hold the tail better no matter which motor/blade you decide to use.

Dude, you are doing this right. A bunch of us have been fixing our birds up, changing this and that, blinging and souping and pimping, flying sims, but you are out there in the real world flying stock, and you have far surpassed me in flying, for sure. That's the way to go about it. I've got so much time and money into mine that I'm almost afraid to try anything radical because I might bend a little blue blingy thing or something, so I'm not progressing nearly as fast as you are. Keep it up, you are an inspiration. When I assemble all my spare parts into another stock blade, I'm going to start flipping and rolling too.

Status: offline 		I second the motion on the DD setup!

I had the dual motors when I added my zoom HH! Same result!

Added the DD, and BAM! Held like a champ!

My DD parts were like 27 bucks...... I am buying another motor for back up it's so good. Prop is probably not as tough, but they are 89 cents...

I balance out with the stock 800 battery not even all the way forward.

The authority and speed of the tail is the big difference from the dual motor setup!

Tail almost seems weightless compared to the dual, IMO!

Status: offline 		right now, i messed with it abit, found that it works best without the remote gain, and i still have to add like -30 revo mixing, i know i shouldn;t have revo when using hh, but dunno why the gyro would respond so slowly though. the tail definitely still has plenty power to hold it during a climbout. i'm using a 1050 batt right now. i didn't go outside to try it yet, still have to get everything setup correctly, only hovered in the living room, and quick jabs of hard throttle to test out the gyro. it holds better than the stock with revo mixing, but still don't understand why i'd even need that much revo if any with a hh gyro.

Status: offline 		Here is my analogy!

CA a 5 lb. sledge hammer to your pro as the tail boom and you have a dual motor setup!

CA a tooth pick to your pro as the tail boom and you have the DD setup!

1. The response is not even close.
2. The single motor is still only 10 bucks, duals go in pairs, 20 bucks..
3. My personal favorite. Balances with the 800 battery not all the way forward AND I removed the quarter taped inside the front canopy! LIGHTER HELI!
4. Props are 89 cents. Black or the beautiful day glow orange!
5. Fits in the stock motor mount! Yes I still have my stock tail boom and mount.
6. It is quieter and sounds really cool.
7. It doesn't look as cool as the dual motor, but oh well.
8. My LHS stocks all the parts.
9. I did by a 19.00 set of allen head screw drivers to get the right size for the set screws on the prop adapter. It's a .035 inchx40 hex head! Wiha brand , german...
10. Out of ideas, but you need 10 reasons, right!

Quit putting it off and spend the 27 bucks. You can always go back and sell your DD setup on this forum...

I may have to order up the parts to try it.

I shy'ed away as a lot of what I read was not super favorable, but now after hearing a direct compare, you have me wondering.

How is it on climb out etc?

i'll say it still has enough power to counter the torque produced in climbouts, that's because when i use revo, it does hold very good. so i'm guessing it's the gyro's fault due to very low gyro gain.
i've been tempted to try the dd setup many times, but my lhs doesn't stock parts for dd. and if i order online, i'll have to pay shipping AND the border crossing fee, and i dun have any other things to buy from helihobby. so i'll come out quite expensive actually, about double the price of the base price.

i do know it holds alot better, since nick maxwell used it with brushless main and a hh and it'll hold insanely well. and can still piro blistering fast to the left (tail) even with full throttle climbouts with brushless main. but too bad my lhs doesn't stock any parts for that. i'll have to mess with it some more. right now, when i jab the throttle for climbouts, it'll hold quite well, but when i back off the throttle, then the tail will wag, my guess is that the tail gain is still too high.

and if any of you are using futaba radios, can you tell me what A and N stands for in the gyro menu? is my guess above right?

Much better on mine because it has less weight and more instantaneous power, IMO!

Tail Rotor blade with mounting hardware 7.00
Two Large Tail Props for Direct Drive 3.50

but i dont see the motor. and if i do make up my mind to get it, what do i need/dont need?
