Ok so I have a big dilemma. Myself and two other guys I work with bought honeybee king 2’s. All of them were setup and we all went through good preflight checks on everything. But all of us are having the problem with the tail spin. One of them you pull to the left until she gets light on the skids, then she starts to jam in circles the opposite direction. On another guy his just spins no matter what. He can pull full right pedal and she still goes spinning like crazy. Mine is not as bad, but she still requires a lot of input to keep the tail from spinning. I have to constantly pull right and that keeps the nose straight. So we have all gone through all the forums and tried all the different things that have been suggested. From the servo movement fore to aft to ensure 90degree, we have checked the belts and the tail rotor spins in the right direction, we have checked and replaced gyros, we have them set on normal then reverse, we have checked the tension on the belt, ect ect ect… I am at my wits end. We cant figure out what is going on and since we are currently deployed in iraq, we cant go down to the lhs and have them look at them. So I am desperately asking for someones help on something else that we may have overlooked or maybe we have collectively gathered the wrong information. Any help would be greatly appreciated and advice given will be implemented. Thanks in advance for reading all this and trying to help us out.

I started out with one of those. Those come with tail problems. I had a heck of a time with mine. You say the tail spins in the right direction. If looking from the right side of the heli, it should spin counter clockwise. What gyro are you using? Stock? If so, it should be on reverse. Turn the heli on (unplug the motor) and manually turn the heli to see which direction the tail blades move. The servo horn should be on the left side of the boom. Make sure the directional switch on the transmitter is in the right direction. The tail blades should be around 7 degrees with no stick input to keep it straight.

Try to give a little more detail about the exact set up and equipment.

details

aaron,
thanks for the input. the tail is spinning the right way. we are all using the stock gyro, esky ek2-0704 set in reverse. we have random setup on the directional switch on the transmitter assuming you are talking about the "gyro sw" on the stock xsmr. we have messed with that one and not seen any difference on either setting. belt doesnt sound or feel like it is binding and tail rotor is going in the right direction with the rotation of the mains. not really sure what our tension is supposed to be set at, but they have very little play and seem pretty snug. everything appears to be installed correctly as far as us noobs can tell. (although between us we have like 80 years of military aircraft experience it isnt helping much...)

particulars of the aircraft:
mine- cnc head and tail and landing gear/43tooth pulley/stock blades main and tail/stock transmitter/brushless motor/stock servos and gyro

coworkers- all stock.

training gear installed on all aircraft.

hopefully this will help some. what about the pitch in the main blades? would this cause tailspin? we are stumped bad...

Tail

Hey, I was at Al Asad for a year in 07 and I had a Belt CP to keep me occupied in the down time. First, make sure your tail pitch is right when you move the sticks. Right rudder should move the nose right and left moves the nose right. I'm trying to insult you but I have seen many get this backwards. Your co worker with the constant spinning, probably has his rudder reversed and gyro reversed so when he tries to compensate it just spins maximum in the opposite direction. Yours is most likely just just the gyro is reversed. If they lift off and then start spinning it is the gyro being reversed. Make sure once you plug in the battery that the helo does not move until the gyro is initialized either. If I remember with that gyro the LED will be solid once set up. Also be sure to set your tail blade pitch to about 5- 7 degrees right rudder with the trim set to center. You have a rate gyro so you need to set it up this way so you trim less when you lift off. It takes some trila and error but you can almost get it to be perfect with minimum trim this way by moving the rudder servo bracket up and down the boom the adjust the initial setting. I would also get a pitch gauge if you don't have one. The mains should have about 5-6 degrees positive at hover. Thsi is normal set-up not 3D. So half stick is 5 degrees, zero throttle should be about -2-0 degrees(preference) beginner should be zero. Max would be no more than 10. 8 is plenty for basic flying around. If you guys have the brushed can motor, the first upgrade I could recommend is the brushless motor. The Esky 3900KV is perfect for the King. The brushed is fine for now but the brushless motors have gobs of power. HeliDriect out of Mass is a great site for parts and I used to get parts to Al Asad in 7-10 days. The guys there are great and when I had an issue with my Belt, they sent me a new motor for free. If you need anything else, let me know and I will help you out.

chris,
thanks for the info. im glad to report that it worked. the only issue i have know is that once i take her up i have to constantly give her right rudder to keep the tail straight on. but there is no uncontrolled spinning. i tried adj the gyro, but it didnt do the trick. i guess i will mess with the blade pitch tomorrow. hopefully that will fine tune the problem. now two of the other three are up and flying. the problem with one of the birds was odd though. the gyro was set to reverse and when he would lift her she would spin like mad. i spun her up slow and looked at the servo as she was going through her wild spin and noticed that when you put left or right rudder, the servo would stay full forward or aft. so i figured the gyro was toasted for whatever reason then thought wait. i flicked the gyro to normal and bam! steady as a rock. then the battery died! but it appears that the gyro is wired wrong internally maybe or mislabled? dont know, just know that it fixed it. but his batt died so he was done for the night. the drawing that you sent showing the angle of the tail was awsome. that helped out the most. now we know where the tail blades are supposed to sit. so thanks for the assist. the other other guy has a busted main rotor head so he is waiting for a cnc that he ordered. but at least three of us are up. thanks for the help! btw, we are in camp taji.

The pitch adjust will fix your issue. I found also, that on the Belt with that gyro, I wouldn't turn up the gain past like 60% or she would wag in FFF. Once you set the pitch you can almost get it perfect and just fine tune it with the rudder trim. The ESky HH gyro 0704A is good HH for cheap. It is just really sensitive to adjust but it holds better than the 0704 rate gyro. A telebee or EFlite G90 is also a good match for these little birds. Just keep the dust out of the bearings as best you can. By buddy used to do brown out landings with his and smoked his tail bearings in about 30 flights. It looked cool but the bearing wore right out as they are not sealed.

Also, don't run your Lipo batteries completely dead. It will kill the life of them. Pick up a cheap LiPo alarm or gauge.

United hobbies has the best prices on LiPos as well.

Another good read, especially with ESky single conversion radio systems. My Belt had some glitches till I fixed the ant routing.

I plan to get a Honeybee3 and I'm responding to this thread because some of you are familiar with this type. It's just about all I can afford now although eventually.. So the honneybee tail spin can be adjusted out - its not a big problem? Also, a flight simulator is offered with it for a few dollars. Is that one going to be good enough?
Another question: how long between flights to avoid burning out the motor. In other words if you have thre batteries can you run it back to back for 3 flights?
Also: If I really need to save up a half a grand in order to not completely waste my money could someone tell me. I already wasted some money on real cheap birds.
Thanks for your advice.

ottoblotto,

Several of us that fly the HBK2 hang out over at the Esky Forum. Come on over. We are glad to help!

I've been flying the HBK2 for about 10 months. The HBK2 was my first CP heli. The HBK2 isn't a T-Rex; however, it's still a quite capable heli when coupled with a good setup and flying skills. It isn't a highly recommended heli for a beginner; however, it can be done. I started out on the ESky Honey Bee FP heli, then I moved up to the HBK2. Anyway, there isn't any one perfect route to learning to fly helis, though.

By the way, if you are interested, below are a couple videos of me flying my HBK2.

racin, thanks for the tip. ill go there and check it out. we are still having a plethora of issues with our acft. mine was doing well until i plugged the 2200mah batt into her and not thinking about the increased torque/power i slammed her quite well into a wall. so im about to leave here and am just going to pack her up and send her home. the other guys are still having a bunch of various problems. so ill point them there also. again, thanks for the tip!

Honey Bee King 2 Tail Spining

Hi All,

I am facing the similar problem of tail spining with my HBK 2 and I have tried evertyhing except replacing the Gyro or the servo. I have a CNC upgrade, with 3800 Kv Brushless and 25amp esc and 1350 mah Lipo battery. The tail blades n servo adjustment looks fine but still it spins towards left (tail in)

Thanks
Amit
