Exian's composite planes

[Richard Roller]

Lovely airplanes. Your technics have my brain working overtime, so many interesting ideas.

Look into the Twin Power series of Lithium Iron Phosphate light weight batterys.... I went from standard motorcycle batterys (lead acid) to Absorbent Glass Matt (AGM) to the Twin Power version of Lipo batterys after repeated battery failures in short lifespan issues.
Very pleased in the reserve power, starting power, ability to hold charge, and rapid charge.

do you have a blog or website , or FB page?

None of the above .... sorry... nor do I have any of these specialized low weight/ high power batteries for sale... Just another fellow passing on some of my actual empirical / experience based knowledge learned the hard way (ie: trial & error...LOL).

I will talk about my composite planes in this dedicated thread.

First project : EXIA, completed and flying well for almost 2 years (70h)
- single seat, under french UL regulation
- wing span 8,2 m
- lenght 5,15 m
- empty weight 130 kg
- MTOW 210 kg
- engine AIXRO XF 40, wankel type, 35hp, consumption 9l/h at 70% power
- tanks in the wings 36l total (wet wings)
- glass sandwich skins with some carbon parts (spars), made in typical composite molds
- special equipements : ballistic parachute (GRS)

Current performance (to be improved with adapted prop that I built but cannot test due to flight bans with COVID19 in France...) :
- Stall speed 65km/h (tested)
- Cruise 180 km/h (real, tested in long cross country flights)
- Top speed 205 km/h
