Hi scimitar, you've got the gyro mounted the wrong way. I just re-read the instructions to my 401 and it clearly states that it must be mounted "floor-like." You must read the instructions for these things - especially as you need to do some switch-flicking to get it set-up correctly too

Where to mount it - I'd make a small platform on the boom close to the crutch. But that's looking at it from my IC version's set-up, I don't know about the Corona at all. Here's a pic of a similar installation: http://www.mh.ttu.ee/risto/rc/logo20...images/011.jpg (took a couple of attempts to get the correct address here!)

Good luck
