I saw a Grob 115 take off from Compton Abbas a couple of weeks ago. It was two up and there was a 5 kt headwind. I had flown my 5 year old daughter down their for some lunch and she was the one that said "Daddy, is that plane going to take off or not".
I looked round and this Grob literally became airborne 80 yds before the end of the runway!
Someone once mentioned on a previous thread about their lack of power and the next circuit this guy did proved that.
He lined up and gave full power. The accelaration was remarkably slow. So slow in fact that someone sitting outside having their lunch actually jokingly held their finger up as if to check it was actually moving!
Are these a/c supplied with very coarse props or are they typically in need of lots of runway?
