Thanks for the comments, guys.
I was recommended this model years and years ago (I built 90% of it about 7 years ago, then my first son was born and it's been in storage until now...). I wanted one that involved quite a bit of building as well as good to fly for a newbee. But there you go.
I've never flown before and I don't have much experience neither in modelling nor the 'science' of flying. I have a club nearby so I'm hoping for some help in getting started. Based on your comments, I think I definitely need to get someone to buddy with me.
The model is quite heavy and, again, I was recommended the 53 engine.
Pete - yes, I've read your build thread with interest.
John - I've downloaded the supercup from FMS website and will updated the .par file with what you suggest. Meanwhile, I'm sending you a PM for the v8 version you have written.
Thanks again, all.
Lars
