I have flown both and own an ELA Eclipse. I am 6'4" tall and cannot close the canopy whilst sitting in the pilot seat of a Calidus, so that was ruled out. The Eclipse is a great aircraft but has a couple of problems which can be sorted fairly easily. There are two fuel level sensors low in the fuel tanks that indicate below 25 and 10 litres which have a tendency to leak. However, there is a visual level from 45 litres to zero so the sensors are not necessary. I have had both holes in the tank completely sealed and the sensors removed. Also I am just fitting a DUC Helices Flash-2 propellor as the E-Props six-bladed-propellor has not proved to be reliable. It takes off well, climbs at over 1,100 fpm and cruises at anywhere between 140-160kph with the 914 engine. Seat very comfortable, visibility superb, landing spectacular. Pre-rotate works perfectly. Mine even has heated seats now, although flying in Spain in the Summer does not require such luxury. Space for storage in three separate locations. Must be one of the best out there right now with a few tweaks.
