We had a lot of fun today racing the Semff planes around two simple Pylons. Zero, Bearcat and Mig 3. No matter who ist fastest, we get a lot of close stuations because the planes have similar top speed.

Air Race (3 min 16 sec)

Here is a test flight of my bat, 80cm, Kfm 2 airfoil:

Fledermaus Rc (1 min 18 sec)

Here is a video of my bigger Radius with 55cm span. It is fast. GPS says 160 kph with Gaupner 6x6 prop, 180 kph with aeronaut 6x7 prop.

Radius 275 Speed (3 min 5 sec)

My beautiful Zero lost a dogfight against a Bearcat today. Surprisigly it still flew well after the hit.

Here is my flock of small (40 - 88 cm) and lightweight ( 206 - 255 g) Kfm 2 birds.
