Bruce:

I am very familiar with the runway at Magaliesburg and have had some anxious moments myself over the kopje and power lines to the north when launching my heavily ballasted Jantar-1 with a weak tug (I seem to remember a 150HP Cub?), especially when the grass was a bit long. It's also possible that I have flown the Janus of which you speak (there aren't many in South Africa). Heavy, yes, but a decent cross-country ship.

I am surprised the Lambada does as well at towing (I have flown an identical 100HP Lambada) and while it does perform well, I wouldn't have expected enough surplus thrust for towing, especially a Janus
