not a guru obviously mate but if you want to bring it to the field tomorrow I'm happy to have a look. I have the laptop with me as I was going to be having some more Srimok vbar flights tomorrow. I have a few ideas as to what might be going on. You can always give me a ring too Jamie has my number.

can you post pics of your head setup and vbar mounting fella and i'll try to help.

did you follow the setup videos to the letter?

Sense of Deja Vu here!

Did we not see a similar thread on your Srimok?

No offence intended but maybe learning to walk first would be a good idea FBL is not really for the faint hearted at the best of times?

yes, IMO: forget about flybarless if you don't have the time.
you're better served with a conventional FB heli that flies straight out of the box.

There is nothing worse than a badly set up FBL heli. I'm afraid you'll have to become an expert, since the rave isn't exactly mainstream. Sorry.

That said:
- there's some information here:
An inofficial Mikado V-Bar (V-Stabi) FAQ

- a trim flight won't work any miracles. Make sure that the swash is leveled in setup mode, and the center-of-gravity is right.

- unless you have a ready-made rave setup that is reliable, you have to do the cyclic gain calculation using the spreadsheet tool (see FAQ). Most likely you'll get values outside of the 80..110 window in the first round, and that means you have to change the linkages and do it once again.

- if you had crashes, check the basic setup (the videos on the Mikado website. Most of it should be also covered in the FAQ).

- Flybarless is quite unforgiving with regard to bad mechanical setup. The V-Bar itself is actually rather well-behaved, compared to some competitors' products.


>>and there are many different opinions on how to set these up
to say this very clearly: For the most basic setup, there is exactly one way to do it right.
There are then a dozen remaining parameters to fine-tune the heli to individual needs. But as long as the gain settings etc are in the right ballpark, it will fly already pretty well.

PS: It has happened quite frequently that two servos got mixed up (the one that should be left is on the right). This can in the worst case cause sudden loss of control in the middle of a flight. Double-check the servo layout.

Sort of what I was trying to say but nicer

Hi Chaps

Thanx for posts - yeah, the Srimok turned out to be a personal disaster. urned out to be a broken wire inside a servo....go figure eh!

Ok, well I think that I am convinced - sell the vbar.

BTW, I have many heli's, and thought I would see what the fuss was about fbl - bad move.

Gareth

Just saw your thread on the vstabi forum,did you get sorted past that point.

According to your setup the unit must be mounted upside down with the cables to the front as shown in the latest pc software which shows how to mount unit.

Cannot help much other than to say unless the unit is actually faulty there has to be something set wrong..

>> thought I would see what the fuss was about fbl
FBL -is- really worth it. I don't love my FB helis anymore... the small 550 gets thrown around by the wind, no-can-do about that. In all other respects, it handles just like a .90, for the cost of a .30.

But, you need time to get it right. If you'd convert a more popular heli, it would be rather easy, use the Mikado conversion kit and follow the instructions.

Take a look at my vbar file that I posted for my Rave.

Flies really well with these settings and with the Next D head.
I've got +-13 collective with these settings so try and adjust your servo arms lengths until it matches roughly.
