I am wondering if the spoiler may induce turbulent airflow over the rudder and possibly the elevators and reduce control? Very nice aircraft all the same though.

@bluedog1976 I think that it is just what you say. The designer would give priority to the simplicity

Yes I need BRS when high attiude flite.

What is G rating?

@straighttailpilot If I recall correctly (haven't looked at the plans in years) it's a wood/carbon composite I-beam. The web is 45 degree plywood and the caps are based on spruce u-tube. The u-tubes are filled with carbon fiber and contain a spruce core to form the carbon into square-section tubes. The carbon is tapered towards the tips so the carbon tubes open into u-sections and finally flat sections.

@EngineeringFun G'day... Ah, well, that turns out to be about half right..! jim Maupin's Design IS INDEED a good aeroplane, & they fly well. Though not many people Foot-Launch them, as Jim intended...! But, the entire Tailboom is Carbon Fibre, as are the Control Bellcranks. To see one uncovered, search 'Aerotowing Rogallos', it's on my Playlists. The 1/4 inch Square Spruce is routed with a 1/8 " groove, & then filled with String & Resin. It's FULL of Carbon Fibre. !

the moment arm looks a little short to me!

Nice plane and flight behavior though it seems to me that "Plywood Dragon" would be a better name.

[straighttailpilot]

any tips on the wing spar design?

[bluedog1976]

@fledge2b Yew, something we a lacking in these days of modern technology. The more I have looked into these microlight gliders the more I am fascinated.

Thats a really nice aircraft well done, it floats so nicely.

Are you going to use a ballistic parachute when you do the high altitude testing?

Can you please tell what its G rating is.

Thanks.
