Please note!
These figures have been calculated on computer and are definately not accurate.
The computer, ie, does not know what type of engine you are using.
A 50hp Rotax will outclimb a 50 Hp VW, but the VW can outcruise the Rotax etc.....
Final performance figures will only be available after proper flight testing.!!

Please keep this in mind when reading these predictions.
