3G Problems

Re: 3G Problems

I had that with the pitch trim lever. At first had me stumped

[Tim Procter]

I'm 100% sure this is a setup problem because Matt Long had no trouble like what is descibed here.

Hope you get sorted.

Pitch lever is already inhibited, and the throttle one. Never used them on any of my set ups.
Like I said, everything works as it says in the manual, the tail servo reacts just like all my other helis (which all have Align gyros). I've have not had problems setting this up or fitting any of the parts, but it was very nerve racking flying it this afternoon, especially the second attempt when I knew things were not quite right.

It's a lot of heli sitting there, and when it kept swinging round violently I just called it a day before anyone got hurt. The was no tilting or oscillations in any other direction, it was just having no control on the tail.

I've re-checked everything 10 times, will have to have another go when it's quiet at the field. I'm more disappointed that I didn't get to fly the 700. It was flying so well before changing it to FBL. Maybe a lesson learnt there...if it ain't broke etc.

Thanks for all the ideas, will report back after I've tried again. just one more thing, I've read that you have to get off the floor quickly with the FBL heli's, has anyone else found this to be true ?.

Yes.!!

I had a near misshap one time when attempting to take off.

I have learnt that when engaging the power to the heli do all your cyclic and tail "checks" then start the heli up and do not check again before take off.

It seems to upset the take off proceedure in some way.

When I take off now I take it to the flightline and take off to head height at a great rate, Not the sensible thing to do in normal circumstances but eliminates this tipping over before you fly.

[Jamin_00]

I took off normally on my botched attempt and it was a bit wobbly but took off ok.
This was one thing I was worried about after hearing about this but was told by a friend on here not to worry and just take off normally.

Which I did, but I was told this is different for other fbl systems

This is what i do to prevent any mishaps/turning over when i am about to take off.

I don't use lots of cyclic while the machine is on the ground until its about to take off or has reached a high enough rotor speed.


I try and keep the cyclic inputs as neutral as i can until i am actually taking off.

large amounts of cyclic on the ground can cause the gyros to keep moving and cause a tip over.

This is what I'm worried about, if something is wrong with the tail and I get off the ground, I could end up with a wreck.

Happened to me, lost the tail

Sorry to see that, I'm going to get a cheap hot glue gun as this seems a sensible idea if the plugs are prone to coming out.

Benn looking on other forums, and there seems to be a number of people who have faulty short leads to the sensor. I spoke to Matt, and he was using the long lead, so I've swapped it over.

It wasn't the best flying day, I shredded the TT gears on my pro (came in to land to adjust something and the heli tipped back on a muddy soft spot ). Went to try my new Vision Comp, and the crankshaft nut span loose locking everything up (been waiting ages for the maiden). And finally the 700 problems, which included my starter repeatedly unscrewing the starter wand.

In the end, I just went home........just one of those days.

Re: 3G Problems

Yea it happens

I have a cheap one indoors which I will glue the lead in with and the way I got it set up I'm using the long lead anyway.

Better luck next time hey

[jimheli]

i dont have the 3g ,but i do use vbar ,when i first test eg maiden , i spool up slow get up to speed then i gently get the heli light on the skids , that way if any thing is wrong ,& the heli would start to tip or tail starts to move you can hit hold & sort it out , if all is well you should be fine , i would not just leap up because if something is wrong you may not save it. just take your time on the test

[Si_B]

That was my plan, but as soon as it get lights on the skids, the tail will swing round violently.

Very unerving.

[jimheli]

yes it is a leap of faith going flybarless for the first time , & a small learning curve as its new stuff , as i said i dont have that 3g unit ,but thair must be a way to adjust the tail , maybe you need to put a small amount of pitch to the tail blades if its to counter the main blades .

large amounts of cyclic on the ground can cause the gyros to keep moving and cause a tip over.

Does the Align system actually control full cyclic travel ?

I keep stick movement minimal on the ground and once at the right headspeed just give it a sharp punch of collective to get it into a low hover. I suspect this is more to do with initiallizing the heli on one surface, then walkout to takeoff then the attitude of the heli has changed so the centers are now off a wee bit.

[Tom Burgess]

What is your setup? servos on cyclic for example? reg and so on?

Could this be a case of the current draw being too high and the sensors crapping out like the reports on RR?
