Most versatile wing I've flown IMHO is the teksumo from hk. Mine has been set up as a powered glider to catch thermals, a flat out 100mph +screamer on 5, a cheap fpv rig! and now finally a 50 mph night flyer.
The current setup is light, fast, and efficient. It's running a park 370 outrunner on 3s with a 1500mah pack. At full throttle I get 50 mph flat and level on my Doppler app and 5 mins of flight time, ease back the throttle and it will come in so slow you can catch it out of the air. I can run 30mins at slow speed. At night I run hk red fiber optic cold light strings on the bottom and LEDs on the top. It's a real UFO that gets the neighborhood kids going.
Bar none the best do all plane I have.
