I witnessed launches using the 100-HP Samba (cousin to the Lambada) at the 2000 Worlds in South Africa. As I recall, they restricted it to 15-m ships.. With heavy ships at high density-altitude, acceleration and the take-off run appeared long. Climb rates were a bit lower than with more powerful tugs, as you would expect, but seemed to be satisfactory.

This class of aircraft should work fine as a tug at sea level with light gliders, but might be under-powered for launching ballasted ships or two-seaters at higher density-altitudes.

Let the experiment be done!
