gyro problem

[D21FTA]

hi guys, i have expereince flyin rc helis but none on building etc.

i have a raptor 30 and my gyro is deffinatly messed up.

il get it up to hover and after 3-5 seconds it goes mad and tail rotor just makes it spin in circles.

i think its just a cheappy gyro, gws 03 thing.

im using dx7 spekky tranny and rx. anyone know of anything could cause this or how tos etup the gyro etc

thanks

check the reverse on your gyro and its orientation( is it mounted like it should) and also check your mechanical setup against the user manual then check your gain settings start at 50% if tail is still not holding increase gain bit by bit till it starts to wag then dial down a touch, but best advise i can give is either get someone who knows what they are doing to set it up or buy a decent gyro can get decent used gyro for around 40-50 mark

also after reading your first post about doing 3d with a blade 400, i would strongly recommend u dont attemt 3d with your raptor 30 just yet, main reason is your gyro, its not a headlock gyro its a rate gyro so if u tried to do flips with it the gyro would go mental, another reason is the raptor 30 aint the best at 3d because it lacks in power, if you want to do 3d with a 30 u will need to do a 30/50 conversion to give you the power and a headock gyro and high speed tail servo to keep the tail in check

wasnt really goin to use it for 3d to be honest i would get a t-rex i think but as mrs got me it i wudnt mind throwing it about a bit if u get me. i was thinkin of ditching the gyro as looks a bit cheap n nasty tbh. i will try what you said killer, im kinda thinking it may be upside down as does seem when gyro kicks in it changes pitch of tail wrong direction thanks

I don't know whether your gyro is actually a heli gyro so to speak. Most of the write ups are of plane installations. If I were you I'd give it a miss and fit something made for the job.

I would fit a new heading hold gyro as above, normally if a gyro is reversed wrong it will go into a death spin as soon as it takes off.

A good tail makes a massive difference on a heli.

I don't think that gyro you have is heading hold.

Got a wee rappy 30 myself mate and like already stated "ditch the gyro you already have" and go with something like a futaba gy401, i had one of these and they work a charm. really easy to setup. also what tail servo are you using as this will make a massive difference.
There are bargains to be had with gyro's now most peeps are going FBL .

You will be able to pick up an align gyro for circa £40. Stretch the budget a bit and for approx £60 you will get a spartan ds760, both of which would be perfect for you

Yeh fink deffo guna ditch the gyro. I know not lot bout the fings so can anyone gimme a idiot sentence of headin hold n normal gyro. Fink i got it by the name lol

[LaurenceGough]

Heading hold will as the name suggests keep your tail in one place until you move it. A normal gyro the tail will kind of weather vane with the flight direction.

It is hard to find a heli these days without a heading hold gyro on it.

SOLVED: this has solved the problem, i have no idea why etc but it deffinatly has, i changed from my lipo rx battery back to normal nicad and it works fine ? any reason people ? also high torque servos plugged into gyro whilst on lipo power dont work but do with a old 4.8 (or wotever it is) nicad ? wierd or wot ???

any ideas

[killer4557]

were u running the gyro and tail servo directly from a 2s lipo without a voltage regulator ? if u were it was probably over voltage most tail servos run on 4.8v to 6v any time on 7.2 will burn them out

ah of course, how bloody stupid could i be (embarresed) lol thanks guys
