Gyro Issues on HBK2?

[Talisa]

It might not even be a gyro issue at all (lack of experience to think what else it could be)

Although this question relates specifically to my HBK2 I guess the question stands against any heli unit. I was flying my HBK yesterday and everything was fine. No crashes, tips or anything.

Today I hooked it up to practise and the thing was spinning like a mad thing and no amount of input from the DX7 would stop it spinning around.

Can something literally change overnight to the physics, or do Gyro flip out sometimes, or what? I just can't understand why yesterday all was cool and today it was acting like a wild thing.

Any thoughts on this?

plug in the battery on the flight line and dont move the heli till it has all booted up and initialised (this includes fitting the canopy if necassary)first make sure all your switches are in the correct positions and you have no trim applied

Thanks. I will try that first thing tomorrow. All I noticed was that the red light on the gyro was flashing the whole time.

with ron have had that problem before from being a bit impatient after turning the heli on. The other possibility is that the belt may have got looser, this also happened to me. Somehow i hadn't tightened the tail up properly and it had slipped slightly. but if the gyro is flashing it definately sounds like the former.

[Talisa]

I did as suggested and the thing still spins like a looney thing. The light on the gyro continues to flash the whole time also.

Guess it is back to the model shop tomorrow and see what is wrong. Unless anyone has any other ideas?

has the tail servo slipped up the boom?

edit - forget that - its a gyro problem because of the flashing red light. what tx are you using?

[Boggy]

concidering its so new and set up by SMC take it back and let them have a look Toni

[Talisa]

Hi Boggy, I am intending on being down there first thing with it. Juts hoping it is somethig simple.

I am going to check that the servo etc hasn't moved though as suggested. One thing, should the light on the gyro constantly flash do you know?

Thought I had solved it with a battery problem, however I think it is a gyro problem now as when it works fine the light on the gyro is solid (1 out of 10 times) and then it flashes (9 out of 10) it spins round like a looney.

HBK2 should now be sorted. When I explained to SMC what the symptoms were, the guy I deal with there hooked into my DX7 and removed 'Sub Trims'? Apparently this can on the HBK prevent proper gyro initialisation.

I am confused about one element in that he said that I may have to fly it with constant right applied on left stick.

Would I be correct in thinking you should be able to set it up with the servo possition to not require any rudder trim? Therefore would be a non issue?

Same thing happens with my 450 if I try and attach the canopy while during the gyro/ESC beeping stage.

Once I connect the batt I leave it still until the beeps stop, then attach the canopy and lift off.

Works everytime that way.

yep any sort of trims/subtrims on the rudder channel will prevent the gyro from initializing. always keep them in the middle a leave them there even when the gyro has set and the heli is ready to fly.

also you can fly the king2 and get the tail to hold without having to put in any rudder stick input. all you have to do is hover the heli and note which way the heli turns. if it turns to the left then land the heli and give it some right stick input and note which way the tail servo arm and linkage moves. you want to slide the tail servo on the boom as it it would got the same way as putting right rudder input.

if it turns right then do the opposite. you only need to move the tail servo a little bit or you might go too far and the heli will start turning the other way.

also you want to keep turning the gyro up a little bit at a time untill the tail starts wagging. when it has started wagging the turn it down a little.

if you need any more help or dont understand then send me a pm and we'll got in the chat and i'll talk you through it while your looking at your heli.

cheers

i do the same with my belt cp - only takes a couple of secs with the 401 - takes abit longer with the esky gyro. put the heli on a flat surface and then try and plug the battery in without moving the heli at all untill the gyro has set.

Thanks Matty, I shall try your suggestions and let you know. Hopefully I will be able to work out what you mean without having to pm you and take up your time. I will see how bad it is first. It might be that I can give it some right on the main rudder trim and then look at the setup with no time limit.

Regards & Thanks,
