closer ones lessens the throw. i am using holes closer on swash and the middle hole on servo arm,this looks like a better link geometry.
Ok I missed Mk's first catch on that. Thanks MK too!

Main blade tightness

OK just joined the 4#3B "club" and I have a couple of questions.

I can hover ok but a slight pitch oscillation sets up sometimes any suggestions as to what may be causing this.

How tight should the main blades be in the grips ?

What size screwdrivers do I need for this heli and where can i get them ?

TIA

the pitch oscillation is likely just getting used to the heli but check for loose linkages and that the head looks centered on the button, if its not a c-clip may be missing on the orings .. the blades do NOT need to be tight but they need to be tightened evenly .. i tighten the screws until the screws just feel like they are grabbing .. if u crank them down it will bend the bladegrips and that WILL cause problems and make it much more difficult to get the blades even and possibly make a tracking problem .. and the screwdrivers u can get at radio shack, just a little precision jewelers set ..

No it's not magnetized, but you could make it magnetized.

Hi, I am new here. I have bought a 4#3B couple weeks ago. Seldom crash, perfect condition. Today, I flew it and it screwed up suddenly in the mid air while I was hovering it. Of course, it crashed....and the servos were un-controllable movement...
I disconnected the battery cell and off the TX~~~re-bind it and hope the servos back to normal. But I never get it binded again.

4#3b bind failure (0 min 32 sec)


Does that mean I have to get a brand new 4 in1? Anyppl here got the same exp. like me b4?

Thankz all

Charles

I usually have my blades "just tight enough or snug" so when spooling up they'll straighten. If the stability changes I check the blade first.....

I have a set of those jewelers tools mentioned, a few craftsman and just picked up a MIA tool kit.

These look handy....

If the servos were still trying to move and was stuck then yes you may have fried your 4in1. Did you smell anything after the crash?

I just touch my screw driver to the stock motors and it magnetizes it just enough to pick up the tiny screws. Only holds for a few screws though.

No, nothing at all.
Should I go for the 4 in 1 or TX now? What cause the problem?

Guys, I just use a small magnet (from a kids Magnetix set) and stick it to the blade of the screwdriver part way up. Gives you a strongly magnetic tip for holding screws, and remove it when you don't want the magnetic effect anymore. And you can use one for keeping those teeny screws safe inbetween times. I also use a sheet of thin, dense black foam from a craft shop as a working surface, gives a good contrast for not losing screws and the screws don't bounce on it.

ychar, in your video i notice the heli is powered up before the TX. standard procedure is to power up TX 1st. i doubt your 4 in 1 is fried, try removing the leads from it and cleaing them with some type of cleaner that is safe for palstics, maybe even a silcone spray. make sure the leads are all connected securely and try again. on my blade cx2 sometimes this happens and i just move the lead wires to the 4 in 1 without disconnecting them to the left or right a little and then it binds.
