VX1N Problem

[Rick H]

Hi Guys

After a lot of thought i decided to go FBL. Brought new head new servos and the VX1n and have had my first flight today. I spent many hours reading the instructions(because this is my first FBL) and setting the heli up.

The problem i have is that when i give right rudder (stood behind heli) the heli will tip to the right and also start to move backwards as well, this is the same if i give left rudder the heli will tip to the left and also move backwards and i am not moving the cyclic stick at all fingers off the stick.

When i make no inputs the heli will hover very nice.

When the heli is on the bench everything is working fine. Swash level all linkages at 90 pitch 12 top and bottom and so on rudder also spot on.

Looks like i have missed something somewhere, has anyone got any ideas what i can try.

The heli is a JR Vibe 50nex nitro. 3 new Jr SLS01 Swash servos, new JR SPG01 Rudder servo.

Thanks Rick.

Im assuming you've done the trim flight

Im looking for a vid that Angelos has done on piro optimisation and I can't find it, sorry

Have you set the correct gyro correction on the swash? Tip to the right and the swash goes left and the same to the left and the front and back. Each way should correct by moving the swash the opposite way.

It sounds like you have the sensor selection wrong in the menu, if its all set up wrong it will still fly like it but will handle like a sack of crap.

I should know I did it myself and the tail was crap like yours.

Go to the spartanrc web site Angelos has a seperate forum for the vortex and its setup inc videos made by himself and BobO in america. They help a lot.

Hi Guys

Thanks for your reply's. Have not done the flight trim as it was about 10mph wind here.

Do you have to do the flight trim even thou the helis mechanical setup is spot on.

I will check everything again but i am sure the correct gyro correction on the swash is right tip to the right swash goes to the left, tip to the left goes to the right and the same for the front and back.

Will have a look for the videos.

Thanks Guys very much appreciated.

Kev D is a bit of an expert,i'm sure he will come along and put you right

If you look on you tube you will find all the BobO videos, follow through them great for the first set up.
They are on the VX1 but mostly the same for the VX1n and are using older firmware, so best having print out of latest firmware as well.

One of these videos? I've done the cross calibration on mine, but not a trim flight as I didn't see anything about it in the documentation. Are you the MK Vortex guru Dave?

bugger you beat me too it

Sounds like pyro optimisation to me. A trim flight is a measurement flight it will just give you figures to adjust the mechanical set up of the heli, it has no other influence.

I can smell it, its on its way, maybe the farmers have been muck spreading again?

Your like a piranha when you get the bit in you teeth lol

[raptorheli2]

piro compensation may fix this but the way you describe this it doesn't sound like normal drift to me, unless your heli is WAAAAY out of balance???.

can you replicate the fault on the bench? put in rudder and does the swash move? also try to yaw the heli on the bench and see if the swash moved, if your table is flat then it should be ok.

depending on what you find will depend on where you need to look.

cheers
