Newby with a wiggling tail & helicommand

[sooren]

I have a 450 SE with a helicommand with a 401 gyro. I bought it fully assembled and ready to fly out of the box. And boy did it fly! The first 6 packs quickly whent buy. Just gave it half throtle and it hovered by its self about 4 feet off the ground. It was then easy to start to practice circles, banking to the sides and other simple manovers. on pack seven I got to close to a wire fence and chiped the tail rotors and the drive pinion for the tail rotor came off. Oh well i guess it could have been worse. I replaced the tail rotars with some nice carbon blades, locktite the tail drive pinion back on and refitted the belt and put it all down to the learning curve.

My problem is that I cant get the tail rotar to keep stil on take off. When I get close to the take off point the tail spins roundlike a top.
I looked at the gyro and a light is flashing and I think this may be telling me that the 401 gyro is not in holding mode although I am not sure. Maybe it is ment to be set up this way with the helicommand.
One thing is for sure, no amount of trimming on the Futaba 6ex will stop it.

Please can anybody through any light on it.

As to the hellicommand it is an amazing piece of kit and i am anoyed at myself for flying in a limited space. For newbies they give you a lot of confidence. My son who has never flown before had a battery packs worth and within minutes you would have thought he had been practicing for ages.

What are the gyro setting's in the TX, helicommand has no control over an external gyro..........

[sooren]

The gyro setting is -35%. I noted the settings when I got it. tried it with the gyro set to INH (inhibited) but made no difference so i put it back to the original setting.

Tail wag is a sign that the gain is to high, reduce the gain slightly and try again, it really is a trial and error process.......

My setting are -61 and + 78

[Tim Procter]

35% is very low for a 401 mate..

[Buccaneer]

Have you tried using the helicommand gyro????

[sooren]

I can't understand why it is doing this if I have not altered any settings? Would the carbon rotar blades make a difference?

hi soonen as Buccaneer said the helicommand. as no control over 401 , if you hit the tail and locktite the tail drive pinion , then its probley not set as was before,+ you may have bent the tail shaft aswell, ollso the servo could have moved a littel if its on the boom so its worth a look .

[steve b]

have you checked the mechanical set

[glen_j]

is the tail rotor spinning the correct way?

[sooren]

Well done Glen j

It was indeed the tail rotor going the wrong way round. All I can say is check when fitting or refitting a new belt!

Helicommand and 450SE - difficult to install & set up?

Sooren, sorry to hijack when I've nothing to contribute on your problem (newbie).
You mentioned you used Helcommand - I'm thinking of buying this to save me some of the heartache and money I invested in a less expensive heli than the 450 SE I just bought (I have no clubs nearby with brains to pick).

Sounds like you recommend it - you mentioned it came RTF so you probably had no installation. From your observation would you perceive it as difficult to install and set up? It sounds like it's easy in use?

Thanks!
