Landing gear : it will be a tricycle gear, it has maybe less "sex-appeal" than tailwheel, but the performances are quasi the same and it will be easier to use. And we're not building a racer.
Canopy : tip-up, mainly for esthetical reasons. The access to the instrument panel is easier, but ventilation on the ground might be a small problem, it's not possible to taxi with your elbow sticking out.
Freins : dual brakes, and parking brake
Trims : electric for elevator, electric or manual for ailerons.
Flaps : electric with flaps positionning system.
Steps : the aircraft we have seen show clearly you need steps, so we will have two.
Engine :Van's is recommending using a Lycoming engine . However, there are Lycoming clones on the market, auto engines conversions (Subaru), some diesels are in the making and even a rotary engine (Wankel type). So the thinking is going on..
It is to be noted that Van's is only supplying engine mounts for Lycoming type engines. Depending on engine type, there will be at least one electronic ignition or PMAG.
Propeller : fixed pitch for ease of maintenance.
Electrics : As per Bob Nuckolls (The AeroElectrics Connection), maybe we'll go with the small stanby alternator..
Avionics : At least some good engine monitoring, no vacuum instruments. EFIS type instruments are making great progresses at attractive pricing. To be followed
Nav lights - Strobes - Landing and taxi lights : we'll certainly go with some type of integrated fixtures, as those sold by CreativeAir.

Every options remain open, some will be discussed in later articles.
