UK Rans S4 with reliable little Rotax 447 can use (my 8+years ownership) under 8 L/h, at 57 mph. Slow, but nice flying characteristics. Max cruise ~60.
In USA & France etc. some have the '503' which gives a bit more speed, perhaps safe cruise 60 mph.
Rans S6 all sorts of motors and wing sizes from microlight to S6-116 Gp.A. Plenty of room for two people plus a bit of baggage inside. Cruise from high
60's to ~100 mph. Consumption obviously varies, say from ~10 - 20 L/h.
All have Dacron skins so need inside under cover storage - Chilbolton might be the place to chat up folk if you need (to build) a shed. All 'Permits' catered for LAA whether micro or not, LAA also have web list of willing Inspectors.
