Re: mini pred uncontrolable body spin

Hi there, the problem could well be the gyro 'sense' is reversed...check the gyro..this is the small box mounted above the battery...there is a switch with 'rev' and 'nor'? I have the same heli anyway.

What the gyro is doing, by the sound of it, is that its detecting the swing but its giving the wrong correction..and this will make the tail swing around nice and fast.

Make sure to switch the sense....and make sure to not move the heli at all when you first connect the power...the gyro needs to sense where its pointing.

Advice...seeing as you dont have instructions?

Always switch the radio on FIRST before connecting the battery on the heli...if you dont the heli can easily start up and hurt you and/or destroy itself.

when flying about...once the power starts to fade...LAND the sucker and let the battery cool for a few minutes...then recharge...if the charger is the same heap of crap as I had then it wont have any LEDs so you need to charge for about 3 hrs...BE careful with this...and dont leave it alone...at least place the battery on a fireproof surface...not scaring you but its better to be safe.

If the radio battery starts to show a low reading...DONT fly...change the batterys..the heli WILL crash otherwise.

Make a training hoop for the heli...use light plastic tubing....aim to make a hoop about the same diameter as the rotor...use kebab skewers or something to tie onto the hoop...and then lash this to the skids using elastic bands...you will have a much better training aid which wont bother the heli at all. I use a hoop...much larger...on my Petrol heli...very handy for testing a gyro. It saves the hassle of the heli suddenly ending up on its side if something goes wrong...so make a hoop...very handy.

You might suffer from glitches with the heli and its radio gear...they are notorious for this.

I got fed up with mine doing this...and dont bother flying it anymore...got a Trex 450 instead. This still had issues with glitches...2.4ghz radio gear doesnt suffer from glitches like this...its to do with the motor and ESC dishing out all sorts of 'noise'

Flying...I dont know your level...but if you are learning...just take it easy..and concentrate on the hover for now...dont get carried away.

Other than that? I found the Mini Pred flys well...its quite forgiving from my experience...but for its price? the makers claim it 'rivals the Trex 450' a bold and silly statement.

It depends on what you want to do? if you are convinced the hobby is going to grow on you then you will outgrow the MiniPred for sure...but whatever happens I would enjoy it for what it is..its a useful introduction to collective pitch type rc helis.
