Back around 2006, Robart was the US distributor for Funsonic Turbines, which were built in Luxembourg.

They apparently never sold well over here and quickly faded from the scene, although many German users liked them and some still fly today.

I managed to to find what was purported to be FS70, but looking at what little data I can find, seems to be the earlier FS52 .

The FS70 was an updated version of the FS52 with 18N more thrust, but the same dimensions.


Did anybody here have one of these, or know how to tell the difference between them? The FS70 was an updated version of the FS52 with 18N more thrust, but the same dimensions.

Either way, it is a nice little engine that I am going to try to restore to running.
