THIS THING IS PISSING ME OFF SHOGUN

[Hellboy]

:bomb: :arggg:

IT HAS YET TO HAVE A DECENT FLIGHT!!!!
bought the shogun heli about a year ago....have tried and tried to fly it, i even questioned my setup so i had a pro check it out, a week later and some minor adjustments later.......on throttle up the tail rotaes clockwise until the gyro catches up...my main problem is when i get airborne the heli starts a continious gyration,
nose dips and rises heli tilts left and right in a clockwise sequence about the heli in a matter of seconds the heli is so unstable a landing usually means a tailstrike....i have played with the gain on the gyro, blades are balanced and heli is balanced...some one please help before this heli takes its only good flight to date right to the garbage can....

all the help you pros provide will be appreciated....

This question is not meant to be an insult or slight of any kind. I don't know you so I don't know what kind of experience you have flying helicopters What flying skills do you have? Have you flown anything other than the Shogun? Small electric helicopters are harder to fly than larger ones and large ones are hard enough. All helicopters with tail rotors will rotate to the right until the gyro catches up. Actually it's not the gyro that has to catch up it the tail blades. When you first apply power to a helicopter, especially an electric helicopter, a lot of torque is applied to the head and the helicopter trys to spin in the opposite direction. Since torque has been applied to the head and the tail rotor speed is essentially zero the helicopter trys to yaw and will until the tail rotor comes up to speed. The other movements you describe sound a lot like inexperience as well. Helicopters are basically unstable and their mastery takes a lot of practice.

Although the Shogun has some weak points, properly set-up and flown by an experienced helicopter pilot it flys very well. I fly my Shogun at least four flight a week and since I've replaced the original torque tube with the new one with the bevel gears it has become very reliable.

One more thing. I assume the "pro" that set up you helicopter did a demo flight. If not get someone to set it up and demo it for you. Flying is much harder than setting up once you've set several up. :D

i have a raptor 30 and can fly it decently ....the tail rotor was the least of my troubles, the servo was the problem....
the main problem still occurs and its not a control issue the heli becomes unstable in flight....

[capebob]

Other than a setup problem the only thing I can think of is that your ball links are a little stiff. Properly built and setup the Shogun is no more or less unstable than any other small electric helicopter. Perhaps someone else will have another idea or two.

thanks bob

Hellboy,

I think capebob is right about the tail issue, it's a matter of instant torque transfer from the electric motor to the main blades--until you have sufficient tail rotor authority it's hard to prevent the tail from swinging around as you spool-up.

Regarding the oscillation in the rotor head, I'm assuming you have checked your linkages and head assembly. It may sound silly to you since you're already flying a .30, but light gusts can play havoc with these little helis. Your control problem could be as simple as not being used to the profound effects gusts can have on a heli weighing less than 2 pounds! It's possible you're over correcting. You may want to crank in a little Expo on aileron and elevator till you get used to it. If you're sure that's not the problem, here are a few other things to consider:

Feather Shaft--The Shogun's got a weak one. A bent feather shaft will cause blade tracking problems which could be what's causing your stability problem
Servos--Are they centering and staying centered? I have seen the HS-55 servos "hunt" for center and not follow xmtr stick inputs
Canopy--Make sure the swash plate balls are not contacting the upper cowling at any part of their travel

Let us know how you're getting along with this.

[Hellboy]

I fly indoors in a large sound stage, no gusts....the heli lifts off fine hovers ok for a few seconds then the oscilation starts....slowy it starts.....the nose and tail start doing circles in the verticle axsis while still holding the heading i have checked the linkages and the tension in the main rotor mount....changed radios and the tail works perfectly.now....thanks rick ia appreciate it

[smokin]

Hellboy,

OK, so your tail problem is fixed. What about the controllability issues?

[Hellboy]

same issues the heli does nose and tail go up and down in a circular motion while holding the heading,probem starts small and in a matter of seconds into a hover is going full bore.

[Wardy]

Hi HELLBOY, Im no expert but I do have a shogun v2 2 that flies very well,this was my first ever heli and I didn't have much trouble getting it stable except for HA HA the two straight months of the problem you describe. Under very close inspection i found the bearing in the plastic swashplate had separated from the swashplate itself whilst still being in its seat it was free to move which ever way it wanted under load and it was difficult to detect until i manually put load on it by hand.Check yours out I hope this simple little gremlin is the cause of your probs.
Regards Wardy. :D

[Data]

I think after not posting for almost one year he might have found the problem :wink:

[WillJames]

Wardy was trying to help David.

Or he could have given up the Shoguns like I did for 50 cents on the dollar like I did. :DOH

Valerko has never talked to me again since he bought my Shogun stuff..... He got a damn good deal at least.....

[Wardy]

OK Im new to this forum,I have just noticed the posted date and feel like a goose.
Thanks for not punishing me to much.I will be careful not to put my foot in my mouth in the future. :arggg: :arggg: :oops:

[Tioli]

Don't worry about it wardy, other people read these posts too, so anything you can contribute, even if it is a year late for the original post-er, will surely help somebody new. In fact, if you do a search, who reads the dates? It's the info that's important.

[RICHW]

How tight are your main blades? They should not be locked down, this will induce oscilations.

[tnreefguy]

MY .02 sell it and buy a Trex and never look back. I got tired of working on mine a week just to fly it into the ground. Trex SE baby and never looked back. SHOGUN = CRAP

[Tioli]

I wouldn't call shogun crap--it is what it is. I fly a shogun, a trex se, an mx-400 and sceadu 50. I really enjoy the shogun, but just for cruising around the patch. It makes me smile. I don't try much in the way of aerobatics with it, but it a kick to fly.

[tnreefguy]

Its still crap :smokin:

[borneobear]

I for one would like to thank Wardy for pointing out the swash plate issue. I'll keep that in mind. This kind of tips help.
Thank you. :D

[Tioli]

tnreefguy.

Okay, I guess I gotta admit it is... :smokin:

[tnreefguy]

The reason i call it that is I really put alot of effort into my shogun, and when it was right it flew great. But when it was wrong forget it. My trex has now been through 3 crashes and for less than 100 bucks and minimal setup time its still flying.

[raynmaker]

Well I had been thinking about a trex guess Ill step that up, but I have got to see this shogun fly before it kills me! :dontknow

The swash tip and the blade tip were very usefull thanks. :noteworthy

I have also noticed that you need better servos in these things and a dampened control on the radio (very touchy heli). :glasses2:

[HeliVt]

I have had the same gyration with my walker 35. Its almost the same thing as the shogun. It always happens when my headspeed is to low for being in the air. If you adjust the thottle curve to get the main rotor spinning faster before heli lifts off it should go away. Near the end of the power in the battery pack it will start to Gyrate because the rotor speed drops off but the pitch is high enough to keep the heli in the air.

My first heli was the shogun v2. I still fly it as much as my trex se. They are really different set ups one being norm and one 120 degree. My big problem with the shogun was the gyro and when I read a post I reversed the gyro (switch on gyro) and the shogun flew great. The T-Rex is a huge :) step up and I love it but I will keep my shogun and fly it often as well.
