    gyro

    Assuming you have a tail rotor with adjustable pitch, rotate the heli by hand about the main rotor shaft and watch the pitch of the tail rotor blades. They should move in a direction that, when rotating in the normal direction, would counteract your input.

    gyro

    Seems to me it is very similar. You can just confirm that the tail rotor rotation speed is counteracting the heli rotation in the above test.

    gyro

    Here's something else you could (very, very carefully!) try to be certain you at least have the right sense. This is definitely NOT recommended for anything but very small helis!!!

    Dismount the gyro from the heli but leave it connected. Ensure you can hold it clear of the blades. Run the heli at low speed. Rotating the gyro one direction should cause the heli to rotate in the opposite. If it goes the wrong way, reverse (or invert) the gyro and try again.

    I don't understand what you are trying to say.

    I recommend you seek out local help.

    I got the same prob

    I got the same problem and my Hummingbird is brand new , once the heli is 2 feet off the ground it won't stop spinning..
    I give it counter ruder but just slows it down it still keep spinning.
    Sooo weird, Im ready to throw out the window and getting a Picolo..

    It sounds like you have it backward. When (standing behind the heli) you move the tail to the right (counter-clockwise) the tail motor should speed up.

    i did this

    I did this test you sugested and you are right , when i moved the tail the right the tail rotor speed up...so its not bakwards.. maybe the main motor has too much torque for the tail motor, I replaced the stock motor with a Speed 300.
    I think I will put the stock motor back, bye the way with the stock motor it worked fine...

    gyro

    flyflie,
    I am running a 9-tooth pinion on my Speed 300 (6 volt) with a stock tail motor and it works just fine. I used to have it running with the (old style) stock mixer (I'm running seperates now) with no problem. It almost sounds like the new mixers don't have enough mixing of the tail motor...

    gyro

    Sounds like the guys who got the early ones got a better product kenru, could be some subs being used to meet demand on the mixers a posibility if these guys are having this much trouble then this will make the decission to go seprates or not easy, I'll just order the base kit and do the seprates right from the beginning

    Im thinkin

    Im thinking of doing the same, I think I'll get an electric plane parkflyer instead... I had high expectation of flying the heli in my living room I guess that is just not possible...Im out 500 Plus bucks since I got the complete package and I invested in li-polys and charger and upgraded swash plates and mods and motors.. Grrrrr

    Would someone tell me

    Would someone tell me if I need a new TX for going separates, I have a Hitec-laser4 , I was reading the article on helihobby.com and he is talking about REVOMIX, as a must have for "separetes"
    If my TX is no good which TX would you recommend? I like to be able to use the same receiver I already have "Hitec-feather"
    Thank You!

    gyro

    Don't give up on the Heli, You need room for a parkflyer I've got 2 and the problem with wind etc. In fact I just toasted the Motor on my AirBoss this afternoon nosed in from about 30ft. up didn't do much to the plane but the pack went into the motor a speed 300 with the ESC built on the back shorted the ESC and the Pack fried the motor. plane I can fix in 10 minutes burned electrics about $60 dollars worth. I don't belong to a club so I fly at local parks problem this time of year more people plus the better faster the plane the more room needed / as far as the seprates if you use a Heading Hold Gyro it dose the mixing for you so you can use your 4CH Radio you only need Revo for a standard Gyro, dosen't matter what motor used. only thing is cost of HH Gyro the CSM200 is about $90.00 for the lightend version

    I won't give it up

    I won't give it up Im just a bit frustrated The cost is not a major problem I have spent way more money in stupid things like the casino LOL...90 bucks for HH gyro is not that bad. Ok so with a HH gyro i can use my 4channel thats good news.. So if I was to get a basic Picolo just the frame and use basically the same motor (speed 300) from my hummingbird and the electronics, all I need to get is 2 ESC and a HH gyro?...I got 2 hitec hs55 micro servos, 4 channel Hitec Feather RX,.... i bought 3 packs of 1200-li-polys...and i have the aluminum collar and metal swashplates mods too....
    Should i give it a go>?

    The reason I went to separates in the first place was because the early mixers were very "glitchy" and tended to cook pretty easily.

    Get the HH Gyro and separates. Your Hitec-laser4 will work just fine.
