Those control are set with the gain at the gyros on the KK board at 50%?

Yes you should set the gains at 50% for all gyros to start.

After testing and trimming, my gains ended up around 47%, 47%, and 60%.

Custom throttle curve

Which allows for finer control around the hover point of the craft. It's like expo for throttle.

It never occurred to me to not use a heli model, I was surprised to hear most people used plane mode. I think it's probably me being mainly a heli pilot and being comfortable with that Tx mode, whereas some of the heli features could be intimidating to a plane guy.

I want to disarm my KKboard, but when I plug my lipo, the red LED is flashing quickly and the board doens't want to disarm! What is wrong?

Turn your transmitter on BEFORE you power up the board!

I've tried that too, but the same thing happen...that's why I'm a bit worried. Just before, I calibrated the throttle range, and from this point everything went wrong.

I've had the BMS-385DMAX Digital Servo on order for weeks now with HK. Getting ready to cancel the entire order long with it. Does anyone know a great alternative to this?

I don't like that servo - mine stripped in a crash. I now use a standard size servo, it's bigger and a bit heavier but it hasn't broken after quite a few crashes. You won't be able to mount it the same way though.

Another good alternative is the MG-90 servo.

iv tried a few different servos but the best for your buck so far has to be this one . its crazy strong http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=20571

Thanks guys, I think I'll cancel or order of BMS-385DMAX and give one of those a shot.

Maybe it's better, but then he would have to wait for it again

thats true .
at firs i used a 2.5kgcm servo then a 2.2kgcm serco . both broke quickly . i checked on rcexplore and david uses a 4.2kgcm so i then bought that one coz it was the cheapest digital mg with high torque

When my BMS servo broke I took it apart - and one of the gears was nylon and had stripped. I hated that, as $20 is a lot for me. The servo I'm using now isn't even MG or digital.

 

[jamiedco]

all metal gear servos have one nylon gear in them . the high end ones are replaceable . this saves the electronics if the servo is stalled and it allows that gear to strip . i used hxt900 gears in my small 9g size metal gear servos wen they stripped

Is it normal that I always need to trim (a lot) my tricopter on my transmitter because my yaw makes it drift to one side and my yaw gyro is set at 75% ?

If it's always doing that to the same side, maybe you should adjust the linkage itself? Are you using direct drive? Or a linkage?

 

[jamiedco]

You can also use sub trims to try level it out aswell as if you have a kk2.0 you can trim it in there by adjusting the servo offset but i dont recommend that

 

[Nic]

What's the difference between linkage and direct drive?
